Maintenance – Planned maintenance
Maintenance - 1000h
Park the roller on a level surface.
When checking and making adjustments, the
engine should be switched off and the
emergency/parking brake should be applied,
if not otherwise specified.
Ensure that there is good ventilation (air
extraction) if the engine is run indoors. Risk
of carbon monoxide poisoning.

Replacing the main air filter

Replace the main air filter element when the warning lamp on
the control panel comes on when the engine is running at
maximum speed.
Release the clamps (1), pull off the cover (2), and pull out the
main filter (3).
Do not remove the backup filter (4).
Clean the air filter if necessary, see section Air filter – Cleaning.
When replacing the main filter (3), insert a new filter and refit
the air cleaner in the reverse order.
Check the condition of the dust valve (6); replace if necessary.
When refitting the cover, make sure that the dust valve is
positioned downwards.

Change the hydraulic fluid filter

Always wear protective goggles when working
with compressed air.
Carefully clean around the hydraulic filter.
Remove the filter (1) and take to an environmentally-
compliant waste disposal station. The filter is of the
disposable type and cannot be cleaned.
Make sure that the old seal is not left on the filter head.
Otherwise, there will be a leak between new and used seals.
Thoroughly clean the sealing surface of the filter holder.
Apply a thin coat of fresh hydraulic fluid on the new filter seal.
Tighten the filter until its seal is in contact with the filter holder.
Right after that, turn an additional half revolution. Do not tighten
the filter too hard as this could damage the seal.
Start the engine and check that there is no leakage of hydraulic
fluid from the filter. Check level of fluid in the sight glass (3) and
top up as required test.
