PREVENT BURNS

Hot spraying fluids:
After operation, engine coolant is hot and stored under
pressure. Hot water or steam is contained in the engine,
radiator and heater lines. Skin contact with escaping hot
water
or
steam
• To avoid possible injury from hot spraying water. DO NOT
remove the pressure cap from the surge tank for the
cooling system until the engine is cool. When removing,
depress the red button on top of the pressure cap to
relieve system pressure. Then slowly turn and remove
the cap.
• The hydraulic oil tank is pressurized. Again, be sure to
release all pressure before removing the cap.
Hot fluids and surfaces:
Engine oil, gear oil and hydraulic oil also become hot during
operation.
The engine, hoses, lines and other parts become hot as
well.
• Wait for the oil and components to cool before starting
any maintenance or inspection work.
REPLACE
PERIODICALLY
Rubber hoses that contain flammable fluids under
pressure may break due to aging, fatigue, and
abrasion. It is very difficult to gauge the extent of
deterioration due to aging, fatigue, and abrasion of
rubber hoses by inspection alone.
• Periodically replace the rubber hoses.
Failure to periodically replace rubber hoses may
cause a fire, fluid injection into skin, or the dump
body to fall, which may result in severe burns,
gangrene, or otherwise serious injury.
