4.5 Checking and topping up the hydraulic oil level
1 = Upper limit
3 = Filler hole
Do not top the hydraulic oil over the upper limit marker on the oil level gauge. An excessive
quantity of hydraulic fluid may damage the hydraulic system by applying too much pres-
sure to these components, which would cause a dangerous high pressure leak.

Hydraulic oil
Do not mix different types of oils.If you need to top up the oil with a different make or type
from the oil left in the tank, remove the remaining oil completely.
1. Put the machine in the position shown opposite:
blade back and lowered to the ground, equipment parallel
to the tracks, boom cylinder half out, arm cylinder re-
tracted to the end of its run, bucket teeth on the ground.
2. Stop the engine.
3. Determine the oil level by looking at the hydraulic
tank gauge. The level should be visible in the tank bulls-
eye.
Note
The oil level varies according to the oil
temperature.
•
around the central point of the gauge scale (oil
temperature : 10 to 30°C).
•
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 rear bonnet.
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 engine bonnet.
