NOTICE
Insuffi cient maintenance on the air fi lter
The power of the machine lessens and damage may
occur to the machine.
The fi lter cartridge (Fig. 5/e) for suction air must be
cleaned by blowing through from the inside out once
a month or more often depending on the level of
contamination. In spite of cleaning the filters their
separation efficiency will continue to deteriorate.
Therefore the fi lters should be replaced every six
months.
Changing fi lters:
Unscrew the outlet grid ( Fig. 5/G).
Undo the screw cap (Fig. 5/s) and the knurled knob
(Fig. 5/m). Remove and clean or replace fi lter car-
tridges (Fig. 5/e). Reassemble in reverse order.
WARNING
Danger of injury when dealing with com-
pressed air.
When blowing through with compressed air, solid
particles may be carried along or powder dust swir-
ling around may cause injury to the eyes. Therefore,
when cleaning with compressed air always wear
goggles and a dust mask.
