Description of the machine
The PROXXON BBS/S 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 example. Can be used for de-burring, roughing, fine
grinding, edging, paint-stripping, rust removal
and sharpening tools.
For machining steel, non-ferrous metals, wood
and plastics. Included with the machine are 2 x 5
grinding belts with different grain sizes.
Caution:
Use your belt grinder only in well-ventilated areas. Pay attention to the dust concentration in
the air. Do not use the BBS/S if the surrounding
air becomes dusty.
We recommend you always work with the vacuum cleaner! This not only guarantees clean work
but also reduces the harmful effect of some
dusts!
Caution:
Hold the device by the insulated gripping
surfaces as the grinding band could hit its own
mains cable!

Protection class II device
Please do not dispose off the machine!
Caution:
Always use ear defenders when working.
Operation
The belt grinder is easily guided over the surface
to be ground with the right hand. Hold the BBS/S
as shown in Fig. 2. Make sure you do not obstruct the cooling slots for the motor. Take care
not to apply too much pressure when working.
This causes the belt to wear quickly and, furthermore, will put excessive strain on the mechanics.
The best results are obtained by using moderate
pressure.
Caution:
Ensure that no poisonous dusts can be produced,
for example, when grinding paints which contain
lead, some types of wood and some metals.
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 adjusting 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 anticlockwise will make the belt run further towards
the outside.
Fitting or replacing the grinding belt
In use, the grinding media will wear and the effectiveness of grinding will reduce due to the belt
becoming clogged with grinding dust or the abrasive grits becoming worn. With its rapid tensioning mechanism, the BBS/S 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.
1. Slacken the knurled screw (Fig. 4a).
2. Then push in the belt roller until the slide 2 of
the tensioning mechanism clicks into place.
3. Remove the worn grinding belt 3.
4. Fit new grinding belt taking note of the arrow
for the direction of running (Fig. 4b).
5. Press in the slider slightly to release the
catch. The fork will spring back to its original
position. The belt is now automatically pre-set
to the correct tension by spring pressure.
6. The belt run may possibly have to be re-adjusted using the knurled screw 1.
Care and maintenance
Caution!
Remove the mains plug before carrying out any
maintenance and cleaning work.
Apart from occasional cleaning, the unit is essentially maintenance-free. When cleaning, please
pay attention to the following:
After use
Thoroughly clean the unit of all grinding dust with
a brush or soft cloth. In particular, the dust which
collects in the belt drive must be removed. Cleaning with compressed air, if available, is suitable
for this. However, care must be taken to avoid inhaling the dust. Wear a dust mask if necessary.
Otherwise, no special maintenance actions are
required.
Changing the toothed belt (Fig. 5)
In very rare cases, it may be necessary to replace the drive belt inside the unit due to wear or
breakage. In this case, proceed as follows:
Caution! Risk of injury!
Unplug from the mains in all cases.
1. Remove cover 1 after unscrewing
both screws 2.
2. Unscrew screw 3 and remove collar disc 4
of the upper timing belt pulley.
3. Remove old toothed belt 5 and
fit the new sprocket belt.
4. Reassembly occurs in reverse order.
Disposal
Please do not dispose of the device in domestic
waste! The device contains valuable substances
that can be recycled. If you have any questions
about this, please contact your local waste management enterprise or other corresponding municipal facilities.
