2-23. PRESSURE HAZARDS.
Ensure air pressure is drained to 0 psi (0 kPa) before taking off any air components. If pressure is
not released, components could blow off and harm personnel. The IHMEE air system is pressurized
to 119 psi (820 kPa). Do not drain air from a tank with any part of body in air spray path. Skin
embolisms and/or debris in eyes can occur from released pressure. Failure to comply may result in
injury or death to personnel.
Hydraulic fluid (Dexron III) is TOXIC. Wear protective goggles and gloves; use only in
well-ventilated area; avoid contact with skin, eyes, and clothes. Skin and clothing that come in
contact with hydraulic oil should be washed immediately. Saturated clothing should be removed
immediately. Failure to comply may result in injury to personnel.
The IHMEE hydraulic system operates at oil pressures up to 3,000 psi (20 680 kPa). Never
disconnect any hydraulic line or fitting without first dropping system pressure to zero. Failure to
comply may result in injury or death to personnel.
Always relieve pressure before disconnecting hydraulic or pneumatic lines. Upon completion of work, tighten all connections
before restoring system pressure.
Hydraulic oil under pressure can penetrate skin, causing serious injury, blindness, or death. If a maintenance procedure must
be performed on the hydraulic system, hydraulic pressure must be released prior to beginning any work.
Search for hydraulic leaks with a piece of cardboard, taking care to protect hands and body from high-pressure fluids. If an
accident occurs, seek medical attention immediately. Any fluid injected into skin must be surgically removed without delay.
2-24. FLAMMABLE FLUIDS.
All fuels, most lubricants, and some coolants are flammable. Do not store flammable fluids in cab.
Failure to comply may result in injury or death to personnel.
Never use fuel to clean parts. Fuel is highly flammable. Failure to comply may result in injury or
death to personnel.
No smoking, flames, sparks, or glowing or hot objects allowed within 50 ft. (15 m) of vehicle.
Failure to comply may result in injury or death to personnel.
Handle fuel with care. Do not refuel vehicle while smoking or when near open flame or sparks. Always shut OFF engine
before refueling vehicle. Fill fuel tank and fuel cans outdoors.
