Sanding; Dust Extraction - GMC BSC900CF Manual Del Usuario

to make a trial run on a scrap piece of material to determine
the optimum grades of belt for a particular job.
In order to take full advantage of your sander, always
purchase good quality belts.
Note. After sanding with a belt sander, an orbital sander
should be used to give a better surface finish.

Sanding

1. The sander is designed for sanding wood, metal, plastic
and similar materials. It is used mainly for quickly removing
a large amount of material. Do not use this sander for
sanding magnesium.
2. Ensure that the belt is in
good condition.
3. Plug in the tool to the
power socket.
4. Bring down the sander onto
the work piece and apply
light pressure (Fig. I).
5. Pull up the trigger switch (5)
and allow the belt to reach
full speed before moving it
across the work (Fig. J).
6. Press the lock-on button (4) if
you require continuous operation.
7. Sand with the grain, in parallel
overlapping strokes.
8. To remove paint or smooth
very rough wood, sand
across the grain at 45º in two
directions, and then finish
parallel with the grain.
9. Use the front roller (8) only
to sand corners or irregular
shapes (Fig. K).
10. Lift the sander off the work
before switching off.
11. Remember to keep your hands away from the moving
belt, as it will continue to move for a short time after the
machine is switched off.
12. Wear safety goggles, a dust mask and earmuffs.

Dust extraction

1. Disconnect the plug from the power supply.
2. To remove the dust extraction
adaptor and canister squeeze
the two catches on either side
of the dust extraction adaptor.
The canister and adaptor will
release (Fig. L).
3. Pull the canister away from the
adaptor, remove the dust bag
I
and empty it (Fig. M & N).
J
WARNING: For optimum dust removal, empty the dust bag
when it is no more than half full.
Do not use the dust bag when sanding metal. The hot
metal particles could cause residual wood dust or the bag
itself to catch fire. A vacuum cleaner adaptor can be used
to connect a household vacuum cleaner or workshop dust
extraction system to the sander. The adaptor fits into the
K
dust extraction port (11).
IMPORTANT. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD) protected
supply with a residual tripping current of 30mA or less. Use
of an RCD reduces the risk of electric shock.
