Hot coolant is under pressure. Care should be used when removing surge tank filler cap or inspecting hot
engine coolant leaks. Steam or hot coolant under pressure may cause injury to personnel.
When removing battery cables, disconnect 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.
Battery acid (electrolyte) is extremely harmful. Always wear safety goggles and rubber gloves when
performing battery maintenance. Severe injury may result if acid contacts eyes or skin.
Clean master cylinder reservoir cap and surrounding area before removing cap. System contamination can
result in injury to personnel or equipment damage.
Accidental or intentional introduction of liquid contaminants into the environment is in violation of state,
federal, and military regulation. Refer to Army POL (WP 0001 00) for information concerning storage, use,
and disposal of these liquids. Failure to do so may result in injury or death.
Volatile mineral spirits burn easily and fumes can explode. Do not smoke or allow flames nearby when
using volatile mineral spirits. Failure to do so may cause serious injury or death to personnel.
Engine oil may be hot when it is drained from crankcase. Use caution when removing drainplug from oil
pan. Failure to do so may cause injury to personnel.
Piston is under spring compression. Do not remove snapring until pressure is applied to spring retainer.
Failure to do so may result in injury to personnel.
Main-pressure regulator and valve lockup springs are under spring compression. Do not remove retainer
ring or lower pin until remover/installer is in place, as springs will fly out causing injury.
Torque converter leak test fixture is under pressure. Ensure all air pressure is exhausted from torque
converter prior to removing test fixture to prevent injury to personnel.
Axle is heavy. Axle assembly with differential installed is not balanced and may flip forward or backward if
not properly secured with chains. Ensure personnel are clear before lowering axle. Failure to do so may
result in injury to personnel.
Do not remove lifting device until transmission is stable on holding fixture. Failure to do so may result in
injury to personnel or damage to equipment.
Torque converter must be supported by retaining straps at all times to prevent torque converter from
falling out, causing injury to personnel.
Valve springs are under tension. Decompress spring slowly to avoid injury to personnel and damage to
equipment.
Never add solvents to any kind of epoxy. Injury to personnel may result.
Keep the epoxy mixture container lids closed tight when not in use. Use only in well-ventilated places.
Always wear gloves while working with epoxy as it irritates the skin.
Keep epoxy away from extreme heat and open flame. Most resins are flammable before hardened.
Transmission container is pressurized. Ensure pressure is released before opening container. Failure to do
so may result in injury to personnel.
Ensure transmission is properly supported before removal. Failure to do so may cause injury to personnel
and damage to equipment.
Install transmission jack under transmission to support transmission and prevent injury to personnel.
No personnel is to be under transmission after transmission jack has been removed. Failure to do so may
cause injury to personnel.
