Instruction Manual

English | 13
The surface of the sanding pad (11) is fitted with a hook-
and-loop fastening, allowing sanding sheets with a hook-
and-loop backing to be secured quickly and easily.
Press the sanding sheet (8) firmly onto the underside of the
sanding pad (11).
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet (8) are aligned with the
drilled holes in the sanding pad (11).
Selection of the Sanding Plate
The power tool can be fitted with sanding pads of various
hardnesses, depending on the application:
– Extra soft sanding pad: Suitable for polishing and sensit-
ive sanding even on curved surfaces
– Soft sanding pad: Suitable for all sanding work, universal
application
– Hard sanding pad: Suitable for heavy sanding on flat sur-
faces
Changing the Sanding Pad
Note: Replace damaged sanding pads (11) immediately.
Remove the sanding sheet or polishing tool. Unscrew the
screw (10) completely and remove the sanding pad (11).
Attach the new sanding pad (11) and retighten the screw so
that it is finger-tight.
Note: Pads with diameters of 150 mm and 125 mm have dif-
ferent carriers. The pads can only be fitted to the right power
tool.
Note: When attaching the sanding pad, make sure that the
teeth of the catch mate with the recesses in the sanding pad.
Note: Damaged sanding pads must only be replaced by an
after-sales service centre authorised to work with Bosch
power tools.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
u Avoid dust accumulation at the workplace. Dust can
easily ignite.
When sanding, it is recommended that you connect the
power tool to a dust extractor. The power tool has no blower
of its own; dust bags cannot be used.
External Dust Extraction
Connect the extraction hose (accessory) either to the extrac-
tion pipe (3) or directly to the extraction outlet (4) of the
power tool.
Note: The extraction pipe(3) consists of antistatic material.
If an antistatic extraction hose (accessory) is used in addi-
tion, this will prevent an electrostatic charge from building
on the tool, which can happen on occasion when sanding.
When working without dust extraction (e.g. polishing), you
can remove the extraction pipe (3). To do this, press the re-
lease button (15) and pull the extraction pipe (3) backward
out of the power tool.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Auxiliary Handle
The auxiliary handle (5) enables comfortable handling and
optimum power distribution, with a high sanding removal
rate in particular.
Secure the auxiliary handle (5) in the thread (13) on either
the right or left of the housing.
To achieve better control of the power tool during sanding
applications, it is recommended that you place your other
hand on the front hand rest. The auxiliary handle (5) may ex-
ert lateral forces which could cause the power tool to
wobble. This can result in damage to the surface to be
sanded, as well as the pad.
Guard Ring
The guard ring (12) protects the sanding pad when sanding
areas close to edges. Fix the guard ring (12) onto the power
tool from the front. To remove it, pull the guard ring (12) for-
ward and off by one end.
Operation
Starting Operation
u Pay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230V can also be operated with 220V.
u Products that are only sold in AUS and NZ: Use a resid-
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching On/Off
u Make sure that you are able to press the On/Off switch
without releasing the handle.
To switch on the power tool, push the on/off switch (2) for-
ward.
To switch off the power tool, push the on/off switch (2)
backward.
