Place the roller on a level base. The engine
must be switched off and the parking brake
applied for all checking and adjustments
on the roller unless stated otherwise.
Loosen the cap/breather filter (2) on top of the reservoir
to relieve any excess pressure inside.
Ensure that the breather filter (2) is not clogged, air
must have unobstructed passage 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 round the hydraulic filter. Remove the
hydraulic filter (1) and scrap it. They are of the
expendable type and cannot be cleaned.
Ensure that the old sealing ring is not left on
the filter holder. Leakage may otherwise occur
between the new and the old seals.
Thoroughly clean the sealing surface of the filter holder.
Apply a thin coat of fresh hydraulic fluid on the new
filter seal. 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, which could
damage the gasket.
Start the engine and ensure that there is no leakage of
hydraulic fluid from the filter. Check the fluid level in the
sight glass (3) and top off as required.
Ensure that ventilation (extraction) is
adequate if the engine is run indoors.
Risk of carbon monoxide poisoning.
