NOTICE
Insuffi cient maintenance on the air fi lter
The power of the machine lessens and damage may
occur to the machine.
Vacuum tight suction fi lter (C-VLR 60)
The fi lter cartridge (Fig. 8/f
2
) for the suction fi lter
(Fig. 2/S) must be cleaned monthly or more often
depending on the level of contamination by purging
from the inside outwards. In spite of cleaning the
fi lter its separation effi ciency will continue to deterio-
rate. Therefore the fi lter should be replaced every six
months.
Filter cartridge (Fig. 8/f
2
) can be removed after undo-
ing the tension clamps (Fig. 8/m
2
).
NOTICE
Do not damage the fi lter cartridges when clean-
ing them.
Micro fi lters (C-VLR 100 - 500)
The micro fi lter inbuilt in the intake silencer (Fig. 3/
S

, 4/S

) must be cleaned or replaced more or less
often depending on how dirty the medium in it is by
washing or blowing through.
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 swirl-
ing around may cause injury to the eyes.
Therefore, when cleaning with compressed air always
wear goggles and a dust mask.
