Speed control
You can regulate the rotational speed steplessly
between 310 and 920 rpm using the adjusting
wheel [5-1]. This enables you to optimise the cut-
ting speed to suit the respective material.
Constant speed
The preselected motor speed remains constant
through electronic control. This ensures a uniform
cutting speed even when under strain.
7.3
Changing sanding pads
 Insert an Allen key (size 5) into the Allen screw
[6-1] on the sanding pad.
 Hold the sanding pad securely and turn the Al-
len key to release.
 In order to further ensure optimum axial run-
out, you must fi rst clean the bearing surface for
the grinding disk on the driveshaft.
 Attach the new sanding pad.
 Tighten the screw [6-1].
 Only attach specifi ed sanding pads to the ma-
chine.
 In order to guarantee optimum suction output,
the sealing face between the machine and the
grinding disk is ground in during the fi rst few
minutes after the disk has been changed. Dur-
ing this time, the r.p.m. of the machine is slightly
lower and white foam particles form during the
grinding process. However, they do not damage
the machine.
 If the machine cannot be started directly with a
new sanding pad, rotate the sanding pad a few
times by hand and run in.
7.4
Affi xing abrasives
Compatible StickFix sanding discs are quick and
easy to attach to the StickFix sanding pad. Simply
press the self-adhesive sanding discs [1-4] onto the
sanding pad [6-2]. The adhesive coating holds the
StickFix sanding pad securely in position. Make sure
that the sanding disc holes line up with the suction
holes [7-3]. Tear off the sanding disc when worn.
7.5
Adjusting the internal/external extraction
You can switch between internal and external
extraction depending on the size of the particles
produced by the sanding process.
 Push the switch [7-1] to change between the
two dust extraction modes.

Adjusting the suction power

You can adjust the suction power to match the
surface type, but only when internal extraction is
active (see chapter 7.5).
 Use the adjusting wheel [5-3] to adjust the
suction power.
1: Low suction power
6: High suction power
 Start with a low suction power (position 1) and
slowly increase until you can feel that the ap-
plication pressure has noticeably changed.
 A high suction power makes sanding work on
ceilings and walls less tiring.
 Excessive suction power can cause the machine
to vibrate and become more diffi cult to guide.
The machine may also be overloaded. This
activates the protective circuit. The red diode
fl ashes slowly. The electronic circuit switches
to recovery speed. If this happens, you must
stop working immediately until the machine
has cooled down again.
7.7

Sanding close to edges

The detachable brush segment allows you to re-
duce the distance between the wall/ceiling and the
side of the sanding pad.
 Press and hold the knob [9-1].
 Remove the brush segment [9-2].
 There is a retainer in the lid of the SYSTAINER
for storing the brush segment.
 Hook in the brush segment at the opposite end
to the knob [9-1], swivel towards the sanding
head and engage into position.

ger particles

particles such as
