Prevent Burns; Replace Rubber Hoses Periodically - Hitachi ZW 100-G Workshop 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 pressure 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 PERIODI-
CALLY
•
Rubber hoses that contain flammable fluids under
pressure may break due to aging, fatigue, and abra-
sion. It is very difficult to gauge the extent of dete-
rioration due to aging, fatigue, and abrasion of rub-
ber hoses by inspection alone.
•
Periodically replace the rubber hoses. (See the
page of "Periodic replacement of parts" in the op-
erator's manual.)
•
Failure to periodically replace rubber hoses may
cause a fire, fluid injection into skin, or the front at-
tachment to fall on a person nearby, which may re-
sult in severe burns, gangrene, or otherwise serious
injury or death.
