BAR.
PERSONS HANDLING COMPRESSED AIR MUST WEAR PROTEC-
TIVE GOGGLES.
Moist or oily contamination
Renew the filter cartridge.
CHECKING THE FILTER CARTRIDGE
– Check filter cartridge’s gasket surface „1“for damage.
– Check the filter cartridge for cracks or any other type of
damage to the paper filter by holding it inclined towards
the light or by shining a light source through it.
IMPORTANT! THE SLIGHTEST DAMAGE TO THE
PAPER FILTER RULES OUT IT BEING USED ANY
LONGER.
– Re-assemble the filter cartridge in the reverse order of
work.

HOURS
Cleaning the oil filter
The oil filter should be cleaned at the same time as the
engine oil is changed, since oil escapes when the filter is
removed.
The engine must be standing horizontally and switched
off.
DANGER OF SCALDING FROM HOT OIL! TRAP THE OLD OIL AND
DISPOSE OF IT IN ACCORDANCE WITH LOCAL LEGISLATION.
