Protection class II device
Please do not dispose off the machine!
Risk of injury!
Never work without dust protection
mask and safety glasses. Some dusts
have a hazardous effect! Materials containing asbestos may
not be machined!
For your safety, always wear hearing
protection while working!
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 work-
ing. 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.
Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord.
Cutting acces-
sory contacting a “live” wire may make exposed metal parts
of the power tool “live” and could give the operator an elec-
tric shock.
Caution:
Ensure that no poisonous dusts can be produced,
for exam-
ple, 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 anti-
clockwise 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 ten-
sioning 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 main-
tenance-free. When cleaning, please pay attention to the fol-
lowing:
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. Oth-
erwise, 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, pro-
ceed as follows:
