a. Adhere to Warnings, Cautions and Notes in the TM.

b. General workshop safety practices should always be adhered to in order to protect hearing, vision and prevent injury. Failure to adhere to can cause injury or death to personnel or damage to equipment.

c. Chock tires when parked to prevent unintended movement.

d. Maintain three points of contact to prevent slips and falls. Always use the grab points, DO NOT grab B-Pillar.

e. To prevent bump hazards, be aware of your proximity to the vehicle. Keep body parts clear of labeled pinch points. Be aware of vehicle components that have the potential for movement and could cause additional pinch points.

Pass out the Suspension Lock-out Braces (WP 0165) and explain them. They will have the opportunity to install later in the course.

f. Suspension lock-out braces must be installed prior to crawling under vehicle.

Suspension may lower, crushing personnel. Failure to comply may result in injury or death.

g. Due to its weight, opening and closing the hood is a two-person operation.

h. PPE is required when working around the JLTVA1. Personal Protective

Equipment (PPE) is designed to protect operators from serious injuries resulting from workplace hazards.

1. Hearing protection

a) Wear to protect hearing from various noise levels in the shop

b) Single point hearing protection shall be worn by all personnel within

10 feet of the JLTVA1 when the vehicle is stationary at high idle.

2. Safety glasses. Wear safety glasses to protect eyes from work you or others may be doing. They should be worn when checking the battery.

3. Military helmet/ACH (Advanced Combat Helmet)

a) All operators must wear a military helmet to prevent head or brain injuries

1) An example of a potential hazard is when using overhead lift.

Military helmets may prevent contact to the head.

4. Gloves

a) Use gloves to protect hands from abrasions, cuts, contact with chemicals, and high or low temperatures.

b) Be sure to wear the correct hand protection for the type of work performed.

Explain the appropriate step locations on the truck for performance of required tasks. Explain the proper use of handholds when exiting/entering the vehicle.

Due to its weight, opening and closing the hood is a two-person operation.

Tell students that when maximum capacity crew members are present, the HVAC is to be operated on high with the fresh air vents open. This will maximize proper ventilation.

(Slide #13)

Q: Why should suspension lock-out braces be used when working under the

JLTVA1?

A: To prevent the vehicle from falling on personnel, which could cause injury or death.

Q: What can you do to prevent slipping and falling in the shop?

A: Maintain three-point contact.

Q: Why is it important to adhere to the proper use of handholds when exiting/entering the vehicle?

A: Doors are heavy and pinching or injury to personnel can result.

(Slide #24)

9. High pressure gas suspension

Warning Do not exit vehicle when suspension is being adjusted. Severing, smashing, and crushing of body parts can occur if caught between door and cab. Remain in vehicle until suspension operation has concluded. Failure to comply may result in injury or death to personnel.

a) These settings may take up to 5 minutes to adjust; typically, the suspension adjustment is completed in less than 1 minute.

1) During an operator-initiated adjustment, the engine RPM increase will slowly ramp up to approximately 1550 RPM if the transmission is in neutral and the parking brake is applied. If either the transmission is shifted out of neutral or the service brake is applied during an adjustment, the engine speed will return to normal idle speed. When adjustment selection is aborted, by either the abort selection in the DSDU or by releasing the brake or putting it in gear, the vehicle will be limited to 10 mph

b) If the High-Pressure Gas (HPG) pumps run continuously for 10 minutes, the SPNSN ERROR light will illuminate and the pumps will automatically stop running to prevent overheating. After 5 minutes, the pump time out error will automatically clear, the SPNSN ERROR light will turn off, and the system will allow ride height adjustments again.

c) The suspension system monitors the hydraulic oil temperature to prevent overheating. If the hydraulic oil temperature exceeds 212° F (100° C), the SPNSN ERROR light will illuminate and pumps will automatically stop running. When the hydraulic oil temperature drops back below 200° F (93° C), the SPNSN ERROR light will turn off, and the system will allow ride height adjustments again.

d) The vehicle is equipped with an automatic leveling feature which, if enabled, will attempt to maintain the vehicle at ideal ride height when in operational mode and moving over 5mph. If the automatic leveling feature is disabled or is unable to maintain the truck at the operational height, the suspension not level light may illuminate. If the automatic leveling system is enabled and a significant change to weight or payload occurs, several automatic leveling events may occur before the vehicle reaches ideal ride height. If the automatic leveling system is disabled, changes to weight, payload, and temperature could potentially lead to suspension not level light illuminating. If at any time the suspension not level light illuminates, the automatic leveling system becomes inactive until an operational adjustment is performed. The SPNSN NOT LEVEL light indicates suspension ride height or pressure is outside of expected limits for vehicle. If SPNSN NOT LEVEL light goes off after vehicle starts operating under normal conditions, no action is required. If SPNSN NOT LEVEL light remains illuminated, a suspension ride height adjust operation must be performed. If a significant change to weight or payload of vehicle has taken place, a ride height adjust operation may need to be performed 2 to 4 times to achieve optimal level operation. In a circumstance where the SPNSN NOT LEVEL light comes on after the vehicle has been off, the vehicle will be limited to 18 mph. This can be eliminated by simply selecting operational ride height from the suspension screen and allowing the system to adjust to operational ride height.
