Filter 1
An in-tank filter—Filter 1 (see Figure 2-17)—filters return oil.
Replace the filter element when the fault alarm
comes on and the Filter 1 icon appears in the
Fault Bar of the main display.
Replace the filter element at each oil change
interval, also.
NOTE: It is normal for the fault alarm to come on at startup
when the oil is cold. The fault alarm should turn off
after the hydraulic oil warms up.
To replace Filter 1, proceed as follows (see Figure 2-17
).
1. Stop the engine.
2. Vent the hydraulic tank using either of the vent valves
(see Figure 2-15
).
3. Take precautions to prevent being burned by hot oil.

5. Disconnect the electric cable from the pressure
switch (3).

Do not allow contaminants to enter the hydraulic tank.

cover.
8. Remove the spring (6).

the handle provided and discard it according to local
environmental regulations.

hydraulic tank.
