DAILY CHECKS
To avoid personal injury:
A When operating, keep hands and body inside
of the ROPS / FOPS protective envelope.
A Do not touch the control levers and the pedals
from outside the cab during the engine
running.
For your own safety and to assure the long life of your
machine, a careful check should be made before each
operation.
BChecking Coolant Level
To avoid personal injury:
A Move the excavator to even ground.
A Make sure that the engine is turned off.
A Do not open the radiator cap right after the
engine has been stopped; Serious burns can
occur from contact with escaping hot coolant
fluid.
A Check the coolant level in the recovery tank
only after the engine has cooled down.
A Remove the radiator cap only if absolutely
necessary.
The radiator has a recovery tank. Should the coolant level
in the radiator sink, the water will be automatically be
forwarded to the radiator.
Open the side cover. (See "Opening / Closing of the Side
Cover" in "OPENING AND CLOSING OF COVERS"
section.)
Check the coolant level in the recovery tank and fill up if
necessary. The coolant level should be between the
marks "FULL" and "LOW".
