Prevent Burns; Replace Rubber Hoses Periodically - Hitachi 120-3 class Operator's Manual

PREVENT BURNS

Hot spraying fluids:
• After operation, engine coolant is hot and under pressure.
Hot water or steam is contained in the engine, radiator and
heater lines.
Skin contact with escaping hot water or steam can cause
severe burns.
• To avoid possible injury from hot spraying water. DO NOT
remove the radiator cap until the engine is cool. When
opening, turn the cap slowly to the stop. Allow all pres-
sure to be released before removing 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 RUBBER HOSES 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. (See the page of
"Periodic replacement of parts" in the operator's manual.)
• Failure to periodically replace rubber hoses may cause a fire,
fluid injection into skin, or the front attachment to fall on a
person nearby, which may result in severe burns, gangrene,
or otherwise serious injury or death.
