Hazardous substances may escape from the filter and the oil. Take suitable
precautions (e.g. gloves, goggles or gas mask).
Observe all safety regulations.
Drain the oil (3/2) and reinsert the oil-drain plug.
Support the filter housing by placing, say, two wooden strips (3/1) under-
neath.
Remove the 4 screws (3/9) and put down the filter housing.
Loosen the small-flange connections to the pump’s exhaust port and exhaust
line and remove the lid (3/7).
Loosen 2 nuts (3/3) on the base (3/4) and remove the base.
Replace the used filter elements with new ones. Make sure that the vulcan-
ised on seal of the filter elements is seated in the centering groove in the
housing cover.
When disposing of used oil and spent filter elements, please observe the rel-
evant environmental protection regulations.
Fasten the base again with the aid of the nuts, making sure that the filter ele-
ments fit properly into the apertures in the base and the lid.
Fill oil into the filter housing (for quantity, see Technical Data).
