WARNING SUMMARY

ASBESTOS HAZARD

DO NOT handle brakeshoes, brakedrums, or other brake components unless area has been properly cleaned. There may be asbestos dust on these components which can be dangerous if you touch it or breathe it. Wear an approved fil-ter mask and gloves. NEVER use compressed air or a dry brush to clean brake components. Dust may be removed using an industrial-type vacuum cleaner. Clean dust or mud away from brake components with water and a wet, soft brush or cloth. Failure to follow this warning may result in serious illness or death to personnel.

BRAKE SYSTEM

• DO NOT allow grease to contact brakeshoe linings. Wipe excess lubricant from the brakeshoe linings to prevent grease soaking into the materials. Brakeshoe linings can absorb grease and oil, causing early glazing of linings and very poor braking action. If brakeshoe linings become soaked, notify Direct Support (DS) maintenance shop for replacement. Failure to follow this warning may cause brakes to malfunction, resulting in injury or death to personnel or damage to equipment.

• If brakeshoe lining is replaced, replace all brakeshoe linings on axle. Combination of old brakeshoes with new brakeshoes will cause uneven braking. Accidents causing injury or death to personnel or damage to equipment may result.

• Brake hub (grease cap)/wheel assembly areas may become hot during operations that require frequent or contin-uous braking. Use caution when performing hub and brakedrum PMCS checks. Serious burns may result from contact with hot metal.

COMPRESSED AIR

Compressed air used for cleaning purposes should never exceed 30 psi (207 kPa). Wear protective clothing (goggles/ shield, gloves, etc.) and use caution to avoid injury to personnel.

COUPLING AND UNCOUPLING TRAILER

• Personnel must stand clear of towing vehicle and trailer during coupling and uncoupling operations. Failure to follow this warning may result in injury or death to personnel.

• If trailer is not coupled to towing vehicle, ensure that handbrakes are applied and wheels are chocked (and rear stabilizers are down). Failure to follow this warning may cause trailer to roll, resulting in injury or death to per-sonnel or damage to equipment.

• Do NOT move the trailer laterally (push/pull) trailers using the landing leg/caster as a third wheel or trailer dolly.

Mounting bracket or landing leg/caster failure may cause trailer damage or personal injury.

• Use ground guides and back prime mover to the trailer lunette, NOT vice versa. Failure to follow this warning may result in injury or death to personnel.

• Do NOT use landing leg/caster as a third wheel to pivot/turn trailer around to face the prime mover. Remove the load from the trailer if it must be turned around. Failure to follow this warning may result in serious injury to per-sonnel or damage to equipment.

b Change 3

WARNING SUMMARY - Continued

DRAWBAR AND LUNETTE RING

• Drawbar is heavy - up to 420 lb (190.5 kg) loaded tongue weight. Use front support (landing) leg crank to raise and lower trailer drawbar. If support leg assembly is inoperative, use suitable lifting device to lift the drawbar. If a suitable lifting device is not available, remove load from trailer and use four or more persons to lift drawbar.

Failure to follow this warning may result in serious injury to personnel or equipment damage.

• Keep hands away from lunette ring during coupling/uncoupling operations. Use the landing leg crank to lower/ raise lunette. Realign prime mover tow pintle with lunette as necessary. Failure to follow this warning may result in personnel injury.

DRY CLEANING SOLVENT

Dry cleaning solvent, P-D-680, is toxic and flammable. Always wear goggles and gloves and use solvent only in a well-ventilated area. Avoid contact with skin, eyes, and clothes, and DO NOT breathe vapors. DO NOT use near open flame or excessive heat. The solvent's flash point is 100°F to 138°F (38°C to 59°C). If you become dizzy while using cleaning solvent, immediately get fresh air and medical help. If solvent contacts eyes, immediately wash your eyes and get medical aid.

HEAVY COMPONENTS

Use caution when handling heavy parts. Lifting device is required when parts weigh over 50 pounds (23 kg) for a sin-gle-person lift, over 100 pounds (45 kg) for a two-person lift, and over 150 pounds (68 kg) for a three-or-more person lift. Keep clear of heavy parts supported only by lifting device. Failure to follow this warning may result in injury or death to personnel.

EYE PROTECTION

Wear eye protection when driving heads of rivets or driving screws. Failure to follow this warning may result in eye injury.

IMPROPER CLEANING AGENTS

Improper cleaning methods and use of unauthorized cleaning agents can injure personnel and damage equipment. To prevent this, refer to TM 9-247 for further instructions.

INTERVEHICULAR CABLE

Ensure that intervehicular cable is disconnected from towing vehicle before performing maintenance on electrical system. Failure to follow this warning may result in electrical shock or burns.

REAR STABILIZER

• Rear stabilizer MUST be used during loading and unloading when trailer is not coupled to towing vehicle. Fail-ure to follow this warning may cause trailer to tip, resulting in injury to personnel or damage to equipment.

• Ensure that weight of trailer is on front support (landing) leg or trailer is coupled to towing vehicle before raising rear stabilizer. Failure to follow this warning may cause trailer to tip, resulting in injury to personnel or damage to equipment.

TIRES

Always use a tire inflation cage for inflation purposes. Stand on one side of the cage during inflation, never directly in front. Keep hands out of the cage during inflation. Inflate assembly to recommended pressure using a clip-on air chuck. Do not exceed 50 psi (345 kPa) cold inflation pressure. Failure to follow these instructions may result in injury or death.

1-2 MAINTENANCE FORMS AND PROCEDURES.

Department of the Army forms and procedures used for equipment maintenance will be those prescribed by DA Pam 738-750 as contained in the Maintenance Management Update.

1-3 CORROSION PREVENTION AND CONTROL.

Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in future items.

While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials, such as rub-ber and plastic. Unusual cracking, softening, swelling, or braking of these materials may be a corrosion problem.

If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality Deficiency Report. Use of keywords such as “corrosion,” “rust,” “deterioration,” or “cracking” will ensure that the information is identified as a CPC problem.

The form should be submitted to the address specified in DA Pam 738-750.

1-4 DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE.

For information on destruction of Army materiel to prevent enemy use, refer to TM 750-244-6.

(3)

(4)

(5)

All trailers are designed to be towed by a towing vehicle without airbrake connections. A hand-brake lever and cable assembly located on each side of the trailer activate a service brake at each wheel. Control of each service brake is independent.

In addition to handbrake-activated service brakes, the trailers are equipped with an inertia-ac-tuated hydraulic brake system. For technical principles of operation of this system, refer to sec-tion III of this chapter.

All trailers have a single axle with two wheels.

The trailer suspension consists of one shock absorber on each end of the axle.

Two stabilizers, stored in the front and installed in the rear, provide greater stability when load-ing or unloading cargo when the trailer is not coupled to the towing vehicle.

b. Capabilities and Features.

(1) Maximum towing speeds with maximum payload evenly distributed are:

Highway 55 mph (66.5 km/h)

Secondary Roads 35 mph (56.3 km/h)

Cross-Country 20 mph (32.2 km/h)

(2) Maximum payload varies with model designation. Refer to Paragraph 1-11, Equipment Data.

1-10 DIFFERENCES BETWEEN MODELS.

NOTE

• Light HMMWVs that have been modified have a decal on the rear crossmember where the pin-tle attaches that states: “AUTHORIZED TO TOW TRAILER WITH MAX GROSS WEIGHT OF 3400 LBS”. An MWO tag should also be present on the driver’s side reinforcement panel (just behind the seat) that identifies MWO 9-2320-280-20-7 has been applied.

• Heavy HMMWVs that have been modified have a stencil on the rear bumper reinforcement plate that states: “AUTHORIZED TO TOW TRAILER WITH MAX GROSS WEIGHT OF 4200 LBS.” An MWO tag should also be present on the driver’s side reinforcement panel (just behind the seat) that identifies MWO 9-2320-280-20-6 has been applied.

a. The difference between the M1101 and M1102 cargo trailers is listed on the Identification and Shipping Plates.

The difference between the maximum Gross Vehicle Weight (GVW) is based solely on the towing vehicle. All trailer models can be towed by a HMMWV M1097/M1114 series in accordance with the identification plate.

The M1101 cargo trailer and the trailer chassis can be towed by a HMMWV M998/M1038 series when the GVW does not exceed 3400 pounds. To determine which HMMWV can tow a chassis version of the LLT, look at the trailer data plate that identifies the total system weight. Use a modified light HMMWV if system weight is 3400 lbs or less. Use a modified heavy HMMWV if system weight is 3400-4200 lbs. There are no physical differences between the M1101 and M1102 trailers. Refer to table below for towing vehicle requirements.

b. The data listed on the Trailer Chassis Identification and Shipping Plates is different from both the M1101 and M1102 trailers. In addition, the trailer chassis has no cargo body.
