IMPORTANT - READ AND UNDERSTAND

ERECTING A TOWER SAFELY

Tower safety factors can be determined from the information and engineering details submitted to the local building authorities when applying for a building permit to erect a tower on a particular site. Equally important is the close conformance by the operator to the approved load acceptable for the specific tower design. ALWAYS SEEK ENGINEERING SUPPORT TO

CONFIRM THE APPROPRIATENESS OF THIS TOWER FOR THE INTENDED USE.

The following is an outline of major considerations to be reviewed prior to erecting a tower. Some of this information will be repeated elsewhere in this manual as it is of great importance.

1. Design of the Tower Safe tower erection depends upon the engineering design of the tower for an intended load. This tower has been designed for general use, not pursuant to an operator’s specifications. Therefore, it is imperative that the operator obtains necessary engineering conformation that the tower’s design is appropriate for the operator’s intended use. Consideration must be given to the final tower erection procedures as this involves the installation of the load (antenna, instruments, lighting, cables, platforms, etc.). The installation of the load during this final erection stage is hazardous. Consequently, selecting a tower and assuring that its design is adequate for the intended load is critical to erecting a safe tower.

2. Site Conditions The environmental condition at the tower site is very important to consider before erecting a tower. High winds may swing tower parts while they are being raised and fitted into position. Care must always be taken to avoid the hazards that might occur with wind-gusts. As it is impossible to predict when wind-gusts may occur, caution should always be taken.

Soil conditions at the tower site should always be investigated. The stability of the soil dictates the size and type of trailer jack support footings and guy anchors if utilized. Swampy or wet soil requires a different jack support footing and anchor type than normal or usual footings. The soil conditions should be checked to see if special considerations are necessary. If the appropriate jack supports and anchors, if utilized, are not in place, the tower may become unbalanced.

When erecting a tower on a rocky site, the usual procedure is to drill into rock and install steel anchor tie-points if guying is required. When this is done, the rock should be carefully inspected for fractures. If the anchors are attached to rock that contains fractures, the tower may become unbalanced. Always use caution and inspect tie-points during the erection process and often thereafter.

3. Erection Stresses Towers are designed to hold specific loads when fully erected. During the erection process however, the tower is not at full design strength. Tower erectors should keep this fact in mind when erecting a tower. Heavy loads should not be placed on the tower during erection, or on the tower in places that are not designated to accommodate such loads. If either one of these considerations are ignored, the tower can become over stressed. Over stressing could lead to tower failure during the erection process, shortly thereafter or if bad weather or other adverse situations occur.

4. Basic Safety Procedures For safe tower erection, the following questions should be asked and answered:

a. Has the tower been designed for the intended load? Has an appropriate engineer been consulted?

b. Have the tower site conditions been checked for adequate jack support footings? Has a soils test been made?

c. Have provisions been made for wind-gust during tower erection?

d. Has provision been made to monitor the use of safety equipment while the tower is being erected?

Corrective action is required if the answer to any of these questions is "No".

CONSIDERATIONS / DELIVERY & RECEIPT OF THE

PORTABLE TOWER TRAILER

Section

ITS Model SR-106 Proper Transportation Procedures & Considerations

The SR-106 with no ancillary equipment (i.e. generator, radio equipment cabinet, etc.) weighs approximately 9,800 lbs. The trailer has a Gross Vehicle Weight Rating (GVWR) of 15,000 lb; GAWR 6,840 lbs. each axle. A recommended tow vehicle has a 1-ton or larger capacity.

Always confirm actual weight of load before selecting a tow vehicle.

Towing a tower trailer is a special driving situation that places additional demands on driving skills. Do NOT exceed trailer posted speed limit or recommended trailer tongue weight or tow vehicle capacity!

ITS suggests a few basic tips drivers should know in order to safely and comfortably transport the SR-106 tower trailer:

Weight Distribution For optimum handling, the trailer must be properly loaded and balanced.

Keep center of gravity low for best handling.

Load should also be balanced from side to side for good handling and proper tire wear.

Load must be firmly secured to prevent shifting during cornering or braking, which could result in loss of control.

Prior to Starting Practice turning, stopping and backing up the tower trailer in an area away from traffic.

Backing Back slowly, with someone outside at rear of the tower trailer to guide you.

Place one hand at bottom of steering wheel and move it in the direction you want the trailer to go.

Make small, precise steering inputs, as slight movement of steering wheel results in much greater movement in rear of trailer.

Braking Allow considerably more distance for stopping with the tower trailer attached.

If you have a manual brake controller, “lead” with trailer breaks if possible.

To correct trailer side-sway, touch trailer breaks momentarily without using vehicle brakes.

Downgrades and Upgrades Downshifting assists braking on downgrades and provides added power at the drive wheels for climbing hills.

o Whenever possible, vehicles with trailers should not be parked on a grade. However, if it is necessary, place wheel chocks under the tower’s wheels as follows:

o Apply the foot service brakes and hold.

o Have another person place wheel chocks under the tower trailer wheels on the downgrade side.

o Once the wheel chocks are in place, release foot service brakes, making sure that the chocks are holding the vehicle and tower trailer.

o Apply the parking brake.

o Shift the transmission into P (PARK) with an automatic transmission and make sure it is latched there. If your vehicle has a manual transmission, put the gearshift lever in R

(REVERSE).

NOTE: With 4-wheel drive, make sure the transfer case is not in N (NEUTRAL) (Where applicable).

o To start, after being parked on a grade:

o Apply the foot service brake and hold.

o Start the engine with the gearshift selector lever in P (PARK) on automatic transmission or N (NEUTRAL) on manual transmissions.

o Shift the transmission into gear and release the parking break.

o Release the foot service brakes and move the vehicle uphill to free the wheel chocks.

o Apply the foot service brakes and hold while another person retrieves the chocks.

Acceleration and Passing The added weight of the SR-106 tower trailer can dramatically decrease the acceleration of the tow vehicle-exercise caution.

If you must pass a slower vehicle, be sure to allow extra distance. Remember, you have the added length of the trailer, which must clear the other vehicle before you can pull back in.

Make your pass on level terrain with plenty of clearance.

If necessary, downshift for improved acceleration.

Driving with an Automatic Overdrive Transmission With certain truck automatic overdrive transmissions, towing- especially in hilly terrain may result in excessive shifting between overdrive and the next lower gear.

If this occurs, it is recommended that the overdrive gear be locked out to eliminate the condition and provide steadier performance.

When there is no excessive shifting, use the overdrive gear for optimum fuel economy.

Overdrive also may be locked out to obtain engine braking on downgrades.

Driving with Speed Control When driving uphill with the portable tower trailer, significant speed drops may occur.

A speed drop of more than 8 mph to 14 mph will cancel the automatic speed control.

Temporarily resume manual control through the vehicle’s accelerator pedal until the vehicle levels off.

7 7

Tire Pressure Under inflated tires get very hot and can lead to tire failures and possible loss of vehicle control.

Over inflated tires can cause uneven tire wear.

Tires should be checked often for conformance to cold inflation pressures recommended on the Safety Compliance Certification Label for tires.

On the Road After about 50 miles, stop in a protected location and double-check:

o Trailers hitch attachment.

o Lights and electrical connections.

o Trailer lug nuts for tightness.

o Engine oil- check regularly through trip.

High Altitude Operation Since gasoline engines lose power at a rate of 3% to 4% per 1,000 ft. elevation, a reduction in gross vehicle weights and gross combination weights of 2% per 1,000 ft. is recommended to maintain performance.

Metric Conversion- To obtain information in centimeters, multiply feet by 30; to obtain information in kilometers, multiply miles by 1.6.

Weights to Check Base Curb Weight is the weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers, cargo or any optional equipment.

Cargo Weight includes all weight added to the Base Curb Weight, including cargo and optional equipment. When towing, trailer tongue weight also is part of the Cargo Weight.

Payload is the combined, maximum allowable weight of cargo and passengers that the tow vehicle is designed to carry. It is Gross Vehicle Weight Rating minus the Base Curb Weight.

Gross Vehicle Weight (GVW) is the Base Curb Weight plus actual Cargo Weight plus passengers. It is important to remember that GVW is not a limit or specification- it is the actual weight that is obtained when the fully loaded vehicle is driven onto a scale.

Gross Vehicle Weight Rating (GVWR) is the maximum allowable weight of the fully loaded vehicle (including passengers and cargo). This number- along with other weight limits, as well as tire, rim size and inflation pressure data- are shown on the vehicle’s Safety Compliance Certification Label.

The GVW must never exceed the GVWR.

Gross Axle Weight (GAW) is the total weight placed on each axle (front and rear). To determine the Gross Axle Weights for your tow vehicle and the tower trailer combination; take your loaded vehicle on the scale to get the front GAW. For rear GAW, weigh the tow vehicle with the tower trailer attached, but with just the four wheels of the vehicle on the scale. You get the rear GAW by subtracting the front GAW from that amount.

Gross Axle Weight Rating (GAWR) is the maximum weight to be carried by a single axle (front or rear). These numbers also are shown on the Safety Compliance Certification Label. The total load on each axle must never exceed its GAWR.

Gross Combination Weight (GCW) is the weight of the loaded vehicle (GVW) plus the weight of the fully loaded tower trailer. It is the actual weight obtained when the vehicle and the tower trailer are weighed together on a scale.

Gross Combination Weight Rating (GCWR) is the maximum allowable weight of the tow vehicle and the loaded tower trailer-including all cargo and passengers- that the vehicle can handle without risking damage. (Important: The tow vehicle’s brake system is rated for operation at the GVWR- NOT GCWR.

Separate functional brake systems should be used for safe control of towed vehicles.) The measured GCW must never exceed the GCWR.

Maximum Loaded Trailer Weight is the highest possible weight of a fully loaded trailer the vehicle can tow, based on a minimum tow vehicle GVW. It assumes a towing vehicle with any mandatory options, no cargo, and driver only.

Weight of additional options, passengers, cargo and hitch must be deducted from this weight.

Tongue Weight is another critical measurement that must be made before towing. It refers to the amount of the trailer’s weight that presses down on the trailer hitch. Too much tongue weight can cause suspension/drive train damage, and can press the vehicle down in back causing the front wheels to lift to the point where traction, steering response and braking are severely decreased. Too little tongue weight can reduce rear-wheel traction and cause instability, which may result in tail wagging or jackknifing.

For optimum handling, tongue loads should meet the following requirements (variance for heavier trailers allowed):

For trailers up to 2,000 lbs., not to exceed 200 lbs.

For trailers over 2,000 lbs., 10-15% of trailer weight.

For fifth-wheel trailers, approx. 25% of trailer weight.

To measure actual tongue load, disconnect the trailer and place only the tongue with the coupler at hitch ball height on a scale.

If the tongue load exceeds the upper weight limit, move more of the trailer contents rearward to achieve the recommended tongue load. If the tongue load is less than the lower limit, shift the load forward.

Metric Conversion- To obtain information in kilograms, multiply the pounds by .45; to obtain information in centimeters, multiply feet by 30.

Transporting the Portable Tower Trailer

1. The operator is responsible for any special license or operator permits that may be required. Please check with motor vehicle authorities for any restrictions or regulations.

2. Check the maximum legal towing capacity of the tow vehicle before transporting the equipment. A fully loaded maximum vehicle towing speed of 65 MPH is recommended.

3. Before moving the Portable Tower System with the towing vehicle, check the hitch attachment, chains, electric brakes, all wiring, and attach the emergency breakaway devise (electric brake units only). Check tires and their inflation. With the tow vehicle hooked up to the trailer, check the trailer and tower rear lights and their operation.

Replace any broken or damaged safety lights at once. The equipment must be checked for any loose hardware that might fall off during transport. The overall width of the SR-106 is +/-8'2", the tow length is approximately +/-31'0", and height approximately +/-10’6”.

4. Check that the trailer’s four (4) outriggers are fully retracted and locked. The tower must be in the horizontal position and securely locked to the tower’s frame. Check that the tower control cabinet and storage box are closed and locked. Secure any/all loose deck mounted equipment or accessories. NOTE: The rear outriggers on the SR-106 trailer have two (2) telescopic stabilizing tubes each with their own lock mechanism ~ utilize primary outrigger first ~ confirm that all locks are engaged and secure.

5. The tow vehicle must be equipped with a commercial towing hitch attached to the vehicle frame not the bumper ~ CHECK INDIVIDUAL VEHICLE RATING so as not to exceed towing capacity. The tow vehicle must also be equipped with an electric brake controller. After the trailer is secured to the tow vehicle and the emergency breakaway devise is connected, the trailer’s landing gear may be raised.

6. When towing the Portable Tower System you must obey the trailer mounted safety decals and warnings as well as speed limits and other posted regulations. The trailer may at times, sway from side to side due to road conditions, tires or improper weight distribution. You must slow the trailer and vehicle down to allow the motion to stop.

Delivery and Receipt of the Equipment

Upon receipt of the Portable Tower System, a thorough inspection of all components should be done. If any damage is found, the trucking company that delivered the equipment should immediately be contacted and ITS should be notified of the damage. An extended delay in reporting the damage may result in a rejection of claims by the trucking company and therefore a thorough inspection of all goods received should be conducted at once. If the shipment is damaged it should be noted on the bill of lading. If the damage to the shipment is severe, the shipment should be refused and ITS notified immediately. If damage to a portion of the tower is discovered, DO NOT attempt to operate the tower before advising ITS of the damage. Substitution or use of damaged components is dangerous and could result in equipment failure or serious injury. Modifications, unauthorized material substitution, or failure to follow the safety and installation guidelines will void any warranty.

11. Never try to tilt the tower if the tower is extended ~ Never try to extend or retract the tower with any objects attached to the tower section legs

12. Never allow equipment to fall in a state of disrepair. All damaged equipment must be repaired before operating.

13. Never wear loose clothing that may become caught in moving parts.

14. Never erect the tower in the known flight path of aircraft or around an airport.

15. Never let the tower unit be erected in an area for an extended time without warning signs and a fence to keep the area safe.

Always:

1. Always choose a smooth, level and solid surface area for tower erection.

2. Always check the trailer outrigger and jack locking pins as well as tower bolts to insure they are secure and tight.

3. Always double check trailer mounted levels for jack slippage-double check that the tower is level.

4. Always stay clear of any moving parts.

5. Always stand back if the tower begins to fall or encounters power lines.

6. Always lower the tower to the retracted/horizontal position if the wind is expected to exceed 50 mph.

7. Always use proper tools and safety equipment.

8. Always call the power company if the tower or any other object comes into contact with power lines -

DO NOT remove the object yourself.

9. Always keep the trailer, tower and all components well maintained and routinely inspect for wear and damage that may lead to equipment failure or injury to personnel.

10. Always wear hard hats when working around the Portable Tower Trailer.

11. Always check the Portable Tower System site after a storm for standing water - if found, lower the tower and wait for the ground to dry.

The installation and maintenance of the Portable Tower System can be extremely dangerous due to inexperience, poor planning, or underestimation of dangerous situations. The installation of a tower near power lines can result in serious injury or death. Always use common sense and be aware of your surroundings.

If someone is electrocuted, do not touch the person, the tower, the trailer or the power lines.

Immediately call for emergency services or (911) and notify the power company of the incident.

Under no circumstances should you attempt to remove any tools, parts of the tower or trailer, or any objects that are in contact with the wires until the power company has arrived and declared the situation safe. Always be aware of the possibility for severe injury and/or death that may occur if a person encounters a power wire or any other object that is electrified.

Portable Tower System Site Safety

The selection of a site for the erection of the Portable Tower System is the first step in assuring a safe installation that will provide the operator personal safety and low equipment maintenance. The following are several factors that must be considered when selecting an appropriate site.

1. The proximity of electrical lines to the tower installation is extremely important. The nearest electrical line should be at least two times the tower height from the tower centerline.

2. The site should be smooth, level and hard packed with good drainage for water run off.

3. Other obstructions such as trees that may interfere with tower guy cables, erection and operation must be avoided or removed.

4. The site must be clean and free from debris and any other concern that may present a safety risk.

5. Post signs at the site and guard the guy cable and anchor points from being hit or damaged.

6. Always keep a fire extinguisher and first aid kit at the Portable Tower System site.

7. If the tower is to be erected for an extended period, lights may need to be installed for additional site safety.

Trailer Hitch Point

Site Selection: (Guy Area if Applicable)

** Only a PE Analysis can determine the optimum guy configuration for a client’s specific loading Min. 77’ Radius

If the Tower is to be guyed, the site selected will require an area of at least 154’ circumference/77’ radius to allow for the guy cables. Once the site has been carefully chosen the Tower Trailer should be towed into position and the trailer secured by lowering the trailer’s front jack and deploying the outriggers. Three guy anchor points will need to be installed 120 degrees apart from one another as shown in Figure 3.1 to the right.

DO NOT GUY TO TRAILER’S EXTENDED OUTRIGGERS

Figure 3.1

Guy Anchor Location (If Applicable):

Should the site require that you guy the tower; three points for the anchor installation will need to be determined.

The first anchor is located directly in line with the tongue of the trailer. To find this point, start measuring from the center of the tower forward over the hitch to the maximum distance recommended by a PE analysis (if provided);

no less distance however than 77’0” - this is your first anchor point. The second and third anchor points will be at the same radial distance from the tower with a 120-degree separation between the three (3) anchor points – See Figure 3.1 above and 3.2 – 3.4 below. Never attempt to raise the tower with guy wires secured to anchors.

Determining 120-degree Guy Cable Separation for Rear Outriggers:

- A typical configuration (requires PE confirmation) would utilize a radius of +77’ measured from the center of the tower

- Utilizing a pre-cut minimum +77’ length of cord or cable, loop one end around the bolt head installed at the rear of the trailer; See Figure 3.2 below

- Extend the cord outward from the bolt such that it lays inside the groove cut into each extended rear outrigger;

See Figures 3.3 and 3.4 below

- Keeping the cord inside the groove, extend the cord to its minimum 77’ length; an anchor point has now been established that should have a 120-degree separation from the other two (2) anchors points

NEVER INSTALL GUY ANCHORS LESS THAN 100% OF THE RECOMMENDED DISTANCE

FROM THE TOWER WITHOUT CONSULTING A PROFESSIONAL ENGINEER

ALWAYS TEST FOR APPROPRIATE SOIL CONDITIONS FOR BOTH TRAILER AND OUTRIGGER

JACK PLACEMENT AND GUY ANCHOR INSTALLATION

Guy Anchor Installation & Removal (If Applicable):

The tower may have been equipped with three (3) 60" long earth anchors to secure the tower guy cables. You have located the points that the anchors will be installed in the steps above. Now it is time to put the anchors in the ground. This is a two person job. If installed by hand, a +3 foot long drive rod may be slipped through the eye of the earth anchor with both persons standing and holding the rod. With the anchor attached, you will need to walk in a clockwise circular motion holding the anchor at a 40-degree angle as shown in Figure 3.5 below. The persons turning the anchor will need to keep a constant pressure down in the angle the anchor is to be installed in.

This operation will take about 15 to 20 minutes per anchor to install. In some areas the anchor may need to be installed with a power wrench due to soil conditions. A contractor with the proper equipment will be needed to perform this work. After the anchors are installed, mark the shaft with a grease pencil level with the undisturbed ground around the anchor. You will use this mark to check for anchor creep.

Min. 40° Angle

Notes:

Check the soil conditions at the point where the anchors are to be installed. The soil must meet class 5 soil or better - "Normal". If the soil does not meet the requirements, you will need to relocate to a better site or have a Soils or Civil Engineer define a new anchor to be used, or soil improvements that can be made. Without anchors, the tower cannot withstand the maximum conditions it has been designed for.

ALWAYS TEST FOR APPROPRIATE SOIL CONDITIONS FOR BOTH TRAILER AND

OUTRIGGER JACK PLACEMENT AND GUY ANCHOR INSTALLATION

Anchor Removal:

To remove each earth anchor, use the approximate 3’0” long anchor drive rod and start turning the rod and anchor counter clockwise until the anchor is out. Do not try to pull them out, as you will damage the anchor.

The site of the Portable Tower System after being removed will have holes and indented areas. These areas must be back filled and packed.

Figure 3.5 Earth anchor installed at an approx. 40 degree angle – always install anchor to its full length

WARNING:

DO NOT OVER TORQUE THE EARTH ANCHOR USING

PORTABLE TOWER SYSTEM

OPERATING INSTRUCTIONS

Planning the Tower Erection:

The threat of injury or even death is very real and every precaution should be taken to avoid electrical hazards and the other hazards associated with erection, operation and maintenance of this equipment. Proper tools, equipment, training and adequate experience is essential. All work must be done in accordance with local codes and safety regulations in effect at the time of installation. The operator is responsible for confirming all local zoning restrictions and codes as well as confirming that this tower is appropriate for the intended loads and environmental conditions.

Tilting and Extending the Telescopic Tower:

1. Make sure the hardware (turnbuckle/cable locks) that secure the tower to the tower base has been released.

2. After lowering and securing the trailer’s front landing gear and unhooking the tow vehicle, disengage the release/locking pin (Figures 4.2 & 4.3A) that frees each of the four (4) trailer outriggers (Note that the rear outriggers have two sets of locks and two separate telescopic tubes). Extend each “Primary” outrigger approximately 6” then twist/pull each release/locking pin handle back to its original locked position.

Continue to extend each outrigger until the release/locking pin drops securely into a hole bored into the outrigger tube (extend approx. 1” beyond red line on outrigger – See 4.0 below) ~ the outrigger is now locked. Be careful not to over extend any of the outriggers – confirm that the locking pin has penetrated the hole in the outrigger. Unlock and extend the secondary rear outrigger in the same fashion as the Primary. Attach the adjustable height jacks to the stubs at the end of each outrigger and secure. Using the three (3) or more trailer mounted levels (located on two sides and at rear of trailer - Figure 4.1). Adjust the trailer’s front landing gear and four outrigger jacks until the trailer appears to be level. Start leveling the trailer from side to side turning the jack hand cranks as needed. Once the side-to-side level is achieved, using the front jack and outriggers, level the front to back of the trailer. Do not extend the jacks more than what is needed to level the trailer. Use the jack’s interior drop leg as opposed to the crank handle to achieve your initial height requirement. DO NOT lift the trailer completely off the ground, only apply sufficient pressure to level and stabilize the trailer.

3. With the trailer now level, the next step is to set the tower up with antennae, coax and/or guy cables if utilized. The ITS tower system may have come equipped with a three-arm antenna mount. Three (3) individual mounting arms may be secured and bolted though a separate top hat to the tower’s top plate (Figure 4.3). Client furnished antenna can then be bolted to each of three mounting arms. It is recommended that all the coax/cables run through the tower's cable rings (Figure 4.3). If the tower is to be guyed, snaps on the guy cables may be connected to the color-coded guy ears (Figure 4.3) and extended out in a straight line away from the tower and toward each guy anchor point.

4. Be aware not to exceed the maximum horizontal or vertical load or weight capacity of the tower. Once client provided items are attached to the tower and confirmation has been made that transport locks are released, the tower may now be prepared for tilting into the vertical position. The power control switches are located inside of the tower control box situated on the driver’s side of the tower frame (Figure 4.4).

5. Confirm that the tower’s transport locks (turnbuckle locks) have been released (Figure 4.5) below.

6. Confirm that the tower’s servant bolts have been removed from the tower base assembly (Figure 4.7) below.

WARNING – Always Place Toggle Switch in OFF Position Before Changing Tower Direction

Tilting and Extending (Raising) the Telescopic Tower (Cont):

7. To tilt the tower, a 120VAC/60Hz/1PH power supply must be provided. If a generator is furnished, follow the manufacturer's instructions described in the generator manual. Once the generator has warmed up and is operating within the Manufacturer's requirements or a permanent source of power has been established, place the key in the tower control panel and rotate into the ON position (See figure 4.4) ~ the tower can now be tilted.

8. To begin tilting the tower into the vertical position, place the TILT toggle switch (See Figure 4.4) located in the control box into the TILT/UP position ~ this will engage the hydraulic cylinder and begin the tilting motion.

The tower will tilt from the horizontal to the vertical position automatically. The tilting operation will take approximately 1.0-1.2 minutes. Allow the tower to tilt toward the vertical position until it rests securely against the tower frame – the tower will automatically stop as a limit switch is activated (See Figure 4.6). Always be aware while the tower is in motion – if the tilt limit switch malfunctions, immediately place the tilt switch in the OFF position to stop the tilting motion.

Once the tower is vertical, firmly secure the tower servant bolts into the holes located in the tower’s frame and place the TILT switch into the OFF position. Note the location of the tilt limit switch and Servant bolts (Figure 4.7).

9. With the tower tilted to the vertical position and securely bolted to the tower frame, the tower must again be checked for plumb. A spirit level may be place along a vertical leg of the tower's bottom section or a bubble level may be used to confirm that the tower frame is plumb (Figure 4.8). Re-adjust the four (4) outriggers & trailer jack as necessary until perfectly level (Figure 4.9).

Summary: Tilting the Tower

A. Confirm that the trailer’s outriggers are fully extended, locked and the trailer is level B. Confirm that the Servant Bolts are removed from the tower’s base assembly C. Confirm that the transport tie-downs are released D. Confirm that the tower’s lock mechanism is disengaged E. Confirm that no items are attached to tower sections that may impede tower movement ~ Place toggle switch into the Tilt/UP position ~ tower will begin to tilt

Tilting and Extending the Telescopic Tower (Cont):

10. Once the tower is level and confirmation that (A) the tower’s locking mechanism is released ~ See Tower

Lock Mechanism Below; (B) no brackets, mounts or other items are attached to any of the tower sections in such way as to impede tower movement, the tower is ready to be raised. Position the “SCOPE” toggle switch into the “UP” position ~ (See Figure 4.4). (Likewise, when the tower is to be lowered – “Scope/Down” position).

11. The tower will begin to extend upward and continue until its full height is achieved or the tower’s movement is stopped manually (Toggle placed in Off Position). Once the tower has reached its full height, it will engage a pre-set limit switch stopping the winch motor and automatically stopping the tower (Figure 4.10).
