Bosch Power Tools

Selecting the Sanding Belt

Depending on the material to be worked and the required rate 

of removal, different sanding belts are available:

Operation

Starting Operation

f

Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the 

nameplate of the machine. Power tools marked with 

230 V can also be operated with 220 V.

Switching On and Off

To 

start

 the machine, press the On/Off switch 

5

 and keep it 

pressed.
To lock the 

pressed

 On/Off switch 

5

, press the lock-on button 

7

.

To 

switch off

 the machine, release the On/Off switch 

5

 or 

when it is locked with the lock-on button 

7

, briefly press the 

On/Off switch 

5

 and then release it.

When not using the power tool, switch it off in order to save 

energy.

Preselecting the Belt Speed (PBS 75 AE)

The necessary belt speed can be preselected with the thum-

bwheel 

4

, even during operation.

The required belt speed depends on the material being sand-

ed and on the working conditions, and can be determined by 

practical testing.

Working Advice

The sanding removal rate and the surface quality are mainly 

determined by the selection of the sanding belt as well as by 

the preselected belt speed (PBS 75 AE). The higher the belt 

speed, the more material is removed and the finer the sanded 

surface.
Only flawless sanding belts achieve good sanding capacity 

and make the machine last longer.
Work using the least possible sanding pressure in order to in-

crease the service life of the sanding belts. The machine’s own 

weight is sufficient for a good sanding performance. An exces-

sive increase of the sanding pressure does not lead to an in-

crease of the sanding capacity, but to increased wear of the 

machine and the sanding belt.

Apply the machine to the workpiece only when switched on. 

Work with moderate feed and carry out the sanding with par-

allel and overlapping strokes. Sand in the direction of the 

grain; sanding across the grain produces an uneven sanding 

effect.
Particularly when sanding coats of varnish, sand in the direc-

tion of the grain as the varnish could melt and smear the sur-

face of the workpiece and the sanding belt. Therefore, work 

with dust extraction.
A sanding belt used for sanding metal should not be used for 

other materials.
Use only original Bosch sanding accessories.
Store sanding belts only hanging; avoid creasing, as this 

makes the belts unusable.
The sanding frame (accessory) allows for uniform and con-

trollable removal capacity when surface grinding larger wood-

en surfaces.

Maintenance and Service

Maintenance and Cleaning

f

Before any work on the machine itself, pull the mains 

plug.

f

For safe and proper working, always keep the machine 

and ventilation slots clean.

Remove adherent sanding dust with a brush.

Cleaning the Dust Passage (see figure E)

From time to time, remove the protection cover 

14

 and clean 

the dust passage 

15

 so that the suction capacity remains at an 

optimum level.

If the replacement of the supply cord is necessary, this has to 

be done by Bosch or an authorized Bosch service agent in or-

der to avoid a safety hazard.
If the machine should fail despite the care taken in manufac-

turing and testing procedures, repair should be carried out by 

an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-

clude the 10-digit article number given on the type plate of 

the machine.
