BChecking Hydraulic Oil Level
To avoid personal injury:
A Stop the engine and remove the key before
checking the oil level.
A Before filling oil, wipe away all sand and dust from
around the oil port. Make sure to use an identical type
of hydraulic fluid.
A The excavator has been filled with hydraulic fluid
before delivery. See "RECOMMENDED OILS".
(Do not mix different oils.)
1. Park the excavator on a firm, flat and level surface.
Lower the attachments and dozer blade to the ground
and stop the engine.
2. Check the oil level as to whether it lies on the center of
the gauge at normal temperature (10 to 30 ).
3. Enough oil is present when oil is at center mark.
4. Should the oil level be too low, loosen the oil filling plug
gradually to release pressure in the tank, then fill up
with oil at oil fill port.
BChecking V-belt
To avoid personal injury:
A Stop the engine and remove the key before
checking the V-belt.
A Check the V-belt for cracks and proper tension.
(See "Adjusting V-belt Tension" in "REGULAR
CHECKS AND MAINTENANCE WORK"
section.)
