REGULATING THE SANDING DRUM PRESSURE
4.3 REGULATING THE SANDING DRUM PRESSURE
The lever can be used to set three different drum pressure stages.
These three stages - COARSE / MEDIUM / FINE - are designated on
the notch plate as -GROB / MITT. / FEIN- (Fig. 16).
The pressure stage indications relate to the grit size sequence.
The sanding pressure should be adjusted inline with the grit size
sequence and reduced as the fineness of the grit size increases.
This setting facility permits you to adjust the drum pressure to the
prevailing circumstances.
For example when sanding with grit size 50 in the -GROB (COARSE)-
setting, the same stock removal is achieved as when sanding with
grit size 40 in the -MITT. (MEDIUM)- setting.
In order to avoid dish-outs when sanding soft wood floors, the
sanding pressure should be reduced and the sanding speed in-
creased.
4.4 EMPTYING THE DUST BAG
The dust bag must be emptied when one third full at the latest. Oth-
erwise, suction performance will deteriorate as the filter surface
becomes clogged.
When emptying the dust bag, a respiratory protection mask P3
must be used.

the side cover.

lected using the setting lever.

ATTENTION!
To avoid fire or explosive damage, always remove the dust bag
from the machine following sanding and empty the contents
into a non-combustible container! Seal this container with a
non-combustible cover and always store both the container and
the dust bag in the open!
