Replace the main filter (3) of the air cleaner even if it
has not yet been cleaned five times, see 50 hours with
regard to changing the filter.
If a clogged filter is not replaced the exhaust
fumes will be black and the engine will loose
power. There will also be danger of severe
damage to the engine.

Place the roller on a level surface. Switch
the engine off and push in the reserve/parking-
brake knob for all checking and adjustments on
the roller, unless otherwise specified.
The filter is located to the left inside the frame.
Clean thoroughly around the left inside.
Remove the oil filter (1) and discard it in a safe
manner; it is of the expendable type and cannot
be cleaned.
Make sure that the old sealing ring is not left on
the filter holder. This could cause leakage
between the new and old gaskets.
Thoroughly clean the sealing surface of the filter holder.
Apply a thin coat of fresh hydraulic fluid on the rubber
gasket of the new filter. Screw on the filter by hand.
First screw on until the filter seal lies against the
filter holder. Then screw a further half turn. Do
not tighten the filter too hard; it could otherwise
damage the gasket.
Start the engine and check that the filter does not leak.
Check the hydraulic fluid level in the sight glass (3) and
top off as required.
Make sure that ventilation (extraction) is
adequate if the engine is run indoors. Risk
of carbon monoxide poisoning.
