WARNING SUMMARY
• Hearing protection is required for the driver and co-driver. Hearing protection is also required for
all personnel working in and around this vehicle while the engine is running (reference AR 40-5
and DA PAM 40-501).
• If required to remain inside the vehicle during extreme heat, occupants should follow the water
intake, work/rest cycle, and other heat stress preventive medicines measures contained in
FM 21-10, Field Hygiene and Sanitation.
• Vehicle will become charged with electricity if A-frame contacts or breaks high voltage line. Do not
attempt to leave vehicle while voltage line is in contact with A-frame or vehicle. Leaving the
vehicle may result in injury to personnel.
• Air compressor becomes hot during operation. Allow air compressor to cool before handling, or
injury to personnel may result.
• Do not disconnect air couplings before draining air reservoirs. Small parts under pressure may
shoot out with high velocity, causing injury to personnel.
• Do not disconnect air lines before draining air reservoirs. Small parts under pressure may shoot
out with high velocity, causing injury to personnel.
• Alternator must be supported during removal. Failure to support alternator may cause injury to
personnel or damage to equipment.
• Do not use a dry brush or compressed air to clean brakeshoes. There may be asbestos dust on
brakeshoes, which can be dangerous to your health if you breathe it. (Brakeshoes must be wet and
a soft bristle brush must be used).
• Leaves and plates of assembled spring are under tension. Restrain all leaves and plates while
removing center bolt. Release tension slowly. Failure to comply may result in injury to personnel.
• When assembling plates and leaves with C-clamp, the plates and leaves will be under tension. Use
care not to disturb the assembly until center bolt and nut are tightened. Failure to do so may
result in injury to personnel.
• Axle is heavy. Ensure axle is balanced and personnel are clear before lowering axle. Failure to do
so may result in injury to personnel.
• Battery acid (electrolyte) is extremely harmful. Always wear safety goggles and rubber gloves
when performing battery maintenance. Severe injury will result if acid contacts eyes or skin.
• Do not smoke, have open flame, or make sparks when performing battery maintenance. Batteries
may explode causing severe injury to personnel.
• Remove all jewelry such as rings, identification tags, and bracelets. If jewelry or disconnected
battery ground cable contacts battery post, a direct short can result, causing damage to equipment
or severe injury to personnel.
• When disconnecting battery cables, disconnect the ground cable first. Do not allow tools to come in
contact with vehicle when disconnecting cable clamps. A direct short can result, causing instant
heating of tools, tool damage, battery damage, or battery explosion, and severe injury to personnel.
• Ensure new longer front brake hoses, currently used on 5-ton trucks, are installed on all 2 1/2 ton
trucks. Old shorter front brake hoses are subject to failure during full steering travel and must be
replaced with new longer front brake hoses. Failure to do this may result in injury or death to
personnel.
• Never stand between test vehicles. Assistant must remain in secondary vehicle to engage service
brake if cable snaps or automatic brake fails. Failure to do so may result in injury to personnel.
• All personnel must stand clear during removal of cargo body dropside. Cargo body dropside will
swing free when pins are removed and injury to personnel may result.
• Eye protection is required when using wire brush for cleaning. Failure to do so may result in injury
to personnel.
