Before any work on the machine itself, pull the
mains plug!
Selecting the rubber backing pad
The eccentric sander is fitted with an all-purpose
rubber backing pad of medium hardness. However,
rubber backing pads with varying degrees of hard-
ness may be fitted, depending on the type of applica-
tion (see application table):
Super-soft backing pad:
Suitable for polishing large surfaces and for particu-
larly sensitive sanding work (also curved surfaces).
Soft rubber backing pad:
All-purpose, suitable for all sanding work.
Hard rubber backing pad:
Suitable for high sanding performance, particularly on
large, flat surfaces.
Fitting the sanding tools (Fig. C)
The machine is fitted with a quick-change (connecting
link) system, enabling sanding tools to be changed
easily without the aid of an additional tool.
Before mounting any new sanding sheets 16, dust
and dirt must be removed from the backing pad 12.
Press the sanding sheets or polishing tools onto the
backing pad and make sure that the bore holes of the
sanding sheet match the bore holes on the backing
pad.
Only use original Kress sanding and polishing
tools with the pressure-sensitive connecting link.
Changing the rubber backing pad (Fig. C)
For changing the backing pad 12, remove it from its
carrier plate 15.
Damaged rubber backing pads must be replaced
immediately.
Changing the backing pad carrier plate
(Fig. D)
When changing the backing pad carrier plate 15, pull
off the sanding sheet or polishing tool, respectively.
Loosen screw 17 with a Torx screwdriver and remove.
Hold the backing pad carrier plate 15 firmly and
tighten the screw 17 firmly with a Torx screwdriver.
Dust extraction prevents large accumulations of dust,
high concentrations of dust in the ambient air and
facilitates disposal.
For long periods of working with wood or for commer-
cial use on materials that produce dust that is detri-
mental to health, the machine is to be connected to
a suitable external dust extraction device.
Adapter for vacuum cleaner connection
The adapter enables the sanding dust to be vacu-
umed using a normal household vacuum cleaner.
The rubber reducer can be used for reducing the con-
nection diameter on the diameter of the vacuum
cleaner tube.
Mounting the dust bag (Fig. B)
For smaller sanding jobs the dust bag supplied with
the machine can be used for dust extraction. The
machine has its own effective dust extraction facility
with integrated suction turbine and dust bag.
Push the dust bag with the locking connection 14 from
behind onto the mounting on the blower flange and
press it on. The locking connection engages by spring
pressure.
The dust bag can be taken off by pulling the moulded-
on grip.
The dust bag must be emptied as soon as the suction
strength slackens. To do this, pull the clamp off in the
direction of the arrow and push it on again after emp-
tying.
Sanding surfaces
Only perfect sanding sheets will give a good sanding
performance and protect the machine.
Observe uniform feed. Less contact pressure gives
a better sanding performance and protects the
machine and sanding tools.
Different rubber backing pads and sanding wheels
should be used depending on the material.
The abrasive power and the sanding finish are deter-
mined primarily by the choice of sanding disc (grain),
speed of the rubber backing pad and contact pressure
(ssee application table).
Place the whole sanding area of the eccentric disc
sander onto the material which requires sanding.
Switch on the machine and move over the work-piece,
applying moderate pressure.
