Working Advice
 Always wait until the pneumatic tool has come to a
complete stop before placing it down.
 Make sure that self-adhesive sanding sheets are fitted
concentrically on the sanding plate.
 In case of an interruption of the air supply or reduced
operating pressure, switch the pneumatic tool off.
Check the operating pressure and start again when the op-
erating pressure is optimal.
Sudden loads cause a sharp drop in speed or a complete stop,
yet do not cause damage to the motor.
Sanding Surfaces
– Switch the pneumatic tool on, place the entire sanding sur-
face on the surface to be sanded and move it over the
workpiece with moderate pressure.
The material removal rate and sanding result are primarily de-
termined by the choice of sanding sheet, the pre-selected
speed and the contact pressure.
Only immaculate sanding sheets will deliver good sanding
performance and protect the pneumatic tool.
Pay attention to apply uniform sanding pressure; this increas-
es the working life of the sanding sheets.
Excessively increasing the contact pressure will not lead to in-
creased sanding performance, rather it will cause more se-
vere wear of the pneumatic tool and of the sanding sheet.
A sanding sheet that has been used for metal should not be
used for other materials.
Use only original Bosch sanding accessories.
Rough Sanding
– Attach a sanding sheet with coarse grain.
– Apply only light pressure to the pneumatic tool so that it
runs at higher speed and a higher material removal rate is
achieved.
Fine Sanding
– Attach a sanding sheet with fine grain.
– Move the pneumatic tool with moderate pressure flat on
the workpiece in a circular motion or alternately along and
across it. Do not tilt the pneumatic tool in order to avoid
sanding through the workpiece, e.g. veneers.
You can reduce the sanding plate speed by lightly varying
the contact pressure or changing the speed, although the
random orbit motion is retained.
– Switch the pneumatic tool off after completing operation.

Maintenance and Service

Maintenance and Cleaning
 Have maintenance and repair work carried out only
through qualified persons. This will ensure that the safe-
ty of the pneumatic tool is maintained.
 Regularly measure the no-load speed of the grinder
spindle. If the measured value of the specified no-load
speed exceeds n (see "Technical Data"), you should
0
have the pneumatic tool checked at a Bosch after-sales
3 609 929 C71 | (7.8.13)
centre. If the no-load speed is too high, the application
tool can break; if the speed is too low, the performance de-
creases.
An authorized Bosch after-sales service agent will carry out
this work quickly and reliably.
Use only original Bosch spare parts.
Regular Cleaning
– Clean the sieve at the air intake of the pneumatic tool regu-
larly. For this, unscrew the hose fitting 4 and remove any
dust and debris from the sieve. Afterwards, retighten the
hose fitting again.
– Water and debris particles in the compressed air cause
rust and lead to wear of plates, valves etc. To prevent this,
fill several drops of engine oil into the air intake 3. Recon-
nect the pneumatic tool to the air supply (see "Connecting
the Air Supply", page 17) and run it for 5 –10 seconds,
while catching/picking up the escaping oil with a cloth. Al-
ways carry out this procedure when not using the pneu-
matic tool for a longer period of time.
Scheduled Maintenance
– Clean the gearbox after the first 150 running hours using a
mild solvent. Follow the solvent manufacturers directions
for use and disposal. Lubricate the gearbox using Bosch
gearbox lube. Repeat the lubrication procedure every
300 hours after the initial gearbox service.

– The motor plates should be checked regularly by special-
ised personnel and replaced, if required.
Lubrication of Pneumatic Tools that do not belong to the
CLEAN Product Line
For all Bosch pneumatic tools that do not belong to the CLEAN
product line (these have a special type of compressed-air mo-
tor that functions with oil-free compressed air), oil mist
should be added continuously to the flowing-through com-
pressed air. The compressed-air oiler required for this is in-
cluded in the compressed-air service unit on the line side of
the pneumatic tool (for more details, please refer to the com-
pressor manufacturer).
For direct lubrication of the pneumatic tool or admixtures to
the service unit, use SAE 10 or SAE 20 engine oil.
