Description of the machine
The PROXXON BBS 40 block belt grinder is an
ideal unit for modelmaking, toolmaking and
mould making but is also suitable for small car
repair jobs, such as on the bodywork for exam-
ple. Can be used for de-burring, roughing, fine
grinding, edging, paint-stripping, rust removal
and sharpening tools.
For machining steel, non-ferrous metals, glass,
wood and ceramic. Included with the machine
are 4 grinding belts with different grain sizes.
Caution:
Use your belt grinder only in well-ventilated ar-
eas. Pay attention to the dust concentration in
the air. Do not use the BBS 40 if the surrounding
air becomes dusty.

Operation
The belt grinder is easily guided over the surface
to be ground with the right hand. Hold the BBS
40 as shown in Fig. 2. Make sure you do not ob-
struct the cooling slots for the motor. Take care
not to apply too much pressure when working.
This causes the belt to wear quickly and, further-
more, will put excessive strain on the mechanics.
The best results are obtained by using moderate
pressure.
Caution:
Ensure that no poisonous dusts can be pro-
duced, for example, when grinding paints which
contain lead, some types of wood and some met-
als.
Always use a dust mask when working.
Caution:
The belt grinder is not suitable for wet grinding.
Adjusting the belt run
Caution! Risk of injury!
Please proceed with particular care when adjust-
ing the belt run.
If the belt does not run sufficiently straight or if
the belt runs inwards or outwards, the position of
the front roller and thus the run of the belt can be
adjusted by means of the knurled screw 1 (Fig.
3). Turning the knurled screw clockwise will make
the belt run further towards the inside; turning an-
ticlockwise will make the belt run further towards
the outside.
Fitting or replacing the grinding belt
In use, the grinding media will wear and the ef-
fectiveness of grinding will reduce due to the belt
becoming clogged with grinding dust or the abra-
sive grits becoming worn. With its rapid tension-
ing mechanism, the BBS 40 provides a very
quick and convenient way of changing grinding
belts.
Caution! Risk of injury!
Unplug from the mains before changing the
grinding belt.
Please use only genuine PROXXON spare parts.
