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 cartridges for incoming air (Fig. 4/e) and
blowing air (Fig. 4/f
➝ accessory) must be cleaned
by blowing through from the inside out once a
month or more often depending on the level of con-
tamination. In spite of cleaning the filters their sepa-
ration efficiency will continue to deteriorate. There-
fore the fi lters should be replaced every six months.
Changing fi lters:
Unscrew the outlet grid (Fig. 4/G). Undo the screw
cap (Fig. 4/s) and the knurled knob (Fig. 4/m). Re-
move and clean or replace fi lter cartridges (e) and (f).
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.
