4.5 Checking and topping up the hydraulic oil level
1. Put the machine in the position shown opposite:
blade back and lowered to the ground, equipment par-
allel to the tracks, boom cylinder half out, arm cylin-
der retracted to the end of its run, bucket teeth on the
ground.
2. Stop the engine.
3. Determine the oil level by looking at the gauge on
the machine's left hand cover. The bearing must be be-
tween the gauge's upper and lower markers.
Note
The oil level varies according to the oil
temperature.
• Before start-up, the oil level must be on
or around the central point of the gauge
scale (oil temperature : 10 to 30°C).
• During normal operation, the oil level
must be around the upper limit marker on
the oil gauge scale (oil temperature : 50 to
80°C).
4. If the oil level is below the minimum marker, top
up as follows :
a. Open the left hand cover.
b. Open the hydraulic oil tank opening cap.
c. Top up through the filler hole, keeping an eye
on the gauge located on the tank.
5. Close the tank again.
6. Close the left hand cover.
1 = Upper limit
2 = Lower limit
2= Filler hole
IMPORTANT
Do not top the hydraulic oil over the upper limit marker on the oil level gauge. An exces-
sive quantity of hydraulic fluid may damage the hydraulic system by applying too much
pressure to these components, which would cause a dangerous high pressure leak.
