HYDRAULIC SYSTEM
Place the machine in a horizontal place, bring the blade in contact with the ground, retract the
arm cylinder and bucket cylinder fully, and move down the boom to lower the bucket onto the
ground when executing inspection and/or maintenance of the hydraulic system.
•
Oil is hot immediately after stopping the engine.
Wait until the temperature lowers and start operation then.
•
Hydraulic oil is compressed. If the filter cartridge is taken out in such a condition, oil spouts
out, resulting in a dangerous accident. Be sure to stop the engine and lower the internal
pressure.
Hydraulic Oil Level and Refilling
1. Stop the engine.
2. Check the oil level gauge (1). If the oil level is between
H and L, it is proper.
The oil level differs with the oil temperature. The
following shows the standard.
•
Near the L level before starting operation
(Oil temperature: 10
°
C to 30
°
C)
•
Near the H level during operation
(Oil temperature: 50
°
C to 80
°
C)
3. If the oil level is below the L level, refill hydraulic oil
through the filler port (2).
•
Do not operate the machine if the oil level is
below the
"
L
"
level.
•
Loosen the drain plug and discharge excess oil
if oil is filled over the
"
H
"
level.
Drain the Hydraulic Oil Tank
1. Loosen the drain plug (3) under the hydraulic oil tank to
discharge water and sediment into the container.
2. Tighten the drain plug when clean hydraulic oil is only discharged.
3. Check the hydraulic oil level and refill oil if insufficient.
