Loosen the screw (3).
Open the cover out of the way (4).
Wipe clean around the cover/breather filter (5) before
removing the cover.
Loosen the cap/breather filter (5) on top of the reservoir
so that any overpressure inside is eliminated.
Make sure that the breather filter (5) is not clogged; air
must pass unobstructed through the cap in both
directions.
If clogged in either direction, clean with a little diesel oil
and blow with compressed air until free passage is
assured, or replace the cap with a new one.
Wear protective goggles when working with
compressed air.
Clean thoroughly around the oil filters.
Remove the oil filters (6) and dispose of them
properly. They are not reusable and cannot be
cleaned.
Make certain that the old seal is removed from
the filter head. Leakage will otherwise occur
between the old and the new seal.
Clean the sealing surface of the seal on the filter
housing thoroughly.
Apply a thin coat of hydraulic oil on the new filter seal.
Tighten the filters by hand.
Screw in the filter until the seal makes contact
with the filter head. Then tighten another half
turn. Do not tighten the filter too much.
It could damage the seal.
Start the engine and ensure that no hydraulic fluid is
leaking from the filters. Check the fluid level in the sight
glass (1) and top off as necessary.
Make sure that ventilation (extraction) is
adequate if the engine is run indoors. Risk
of carbon monoxide poisoning.
