6. Enter the area between the left-hand and right-hand platforms behind the mast.
Ensure all surfaces are clean and dry and take great care to avoid slipping!
7. Close the shut-off valve (A) on the back of the hydraulic tank.
8. Clean the area around the suction filter (B) thoroughly before removing the used
filter element to prevent any contamination from entering the hydraulic system.
9. Position a suitable container under the used filter element to collect any
escaping oil.
10. Unscrew and remove the used filter element. Use a filter wrench if required.
11. Check the sealing surfaces and threads on the filter mount and on the new filter
element and clean if necessary.
12. Apply a thin film of clean hydraulic oil to the O-ring on a new suction filter
element.
13. Screw the new filter element on to the filter mount until it is hand tight only. DO
NOT over tighten the filter element. Use a genuine OEM component.
14. Open the shut-off valve on the back of the hydraulic tank before starting the
engine.
15. Start the engine and check around the suction filter for leaks. Repeat the check
when the hydraulic oil has reached operating temperature.
16. Top up the hydraulic oil if necessary (see section 5.6 ‘Checking Hydraulic Oil
Level’ on page 72).
17. Dispose of waste oil and used filter elements in compliance with local
regulations.
18. Clean up any oil spills immediately.
Return Filter
The hydraulic oil return filter is mounted on the top of the hydraulic tank. It filters the oil
as it is returned from the valve chest to the tank.
The return filter element must be replaced after the first 100 hours of operation and
then at regular intervals in accordance with the maintenance schedule.
To change the return filter element:
1. Stop the truck in a designated service
area.
2. Lower the mast fully and tilt the mast
forward fully.
3. Turn the ignition key switch to the ‘0’ off
position, then remove the key.
4. Ensure all parts concerned are cool
enough to touch, otherwise wear heat
resistant gloves before proceeding.
5. Clean and dry the return filter (A) and
the surrounding area thoroughly to
prevent any contamination from entering
the hydraulic system.
