4. Adjust the necessary speed by rotating the regulator
thumbwheel (12) (for MBS 976Е only). The maximum
speed corresponds to the symbol G, and the mini-
mum speed - to symbol A. Sanding efficiency and
surface quality are determined by belt grade and
speed. The higher the belt speed, the more material
is removed and the finer the sanded surface.
5. Bring down the sander onto the work piece and apply
light pressure.
(Fig. 7)
6. Press the trigger and allow the belt to reach full
speed before moving it across the work.
7. Press the lock on button (4) if you require continuous
operation.
8. Sand with the grain, in parallel overlapping strokes.
9. To remove paint or smooth very rough wood, sand
across the grain at 45º in two directions, and then
finish parallel with the grain.
10. Use the front roller (8) to sand corners or irregular
shapes.
11. Lift the sander off the work before switching off.
12. Remember to keep your hands away from the mov
-
ing belt, as it will continue to move for a short time
after the machine is switched off.
13. Wear safety goggles, a dust mask and earmuffs.
DUST EXTRACTION
1. Disconnect the plug from the power supply.
2. Firmly push the plastic nozzle of the dust bag (3) onto
the dust extraction port (11).
(Fig. 8)
3. Before removing the dust bag, first disconnect the
plug from the power supply.
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.
Cleaning the bag:
Dismount and empty the dust bag,
tapping it gently to remove dust. On occasion, slip the
bag off of the frame and turn bag inside out. Brush dust
off of the lining using a soft brush.
4. A vacuum cleaner adapter can be used to connect a
household vacuum cleaner or workshop dust extrac-
tion system to the sander.
5. An adapter is fitted into the dust extraction port (11).
STATIONARY USE
(FIG. 9)
This machine can be mounted to a bench for stationary
use.
▪ Place the rubber pad (15) on the bench as indicated
by the inscriptions. Never mount the machine onto the
bench without the rubber pad.
▪ Turn the machine upside down and centre it on the
rubber pad. The mounting holes (17) shall face to
-
wards the operator.
▪ Insert the mounting pins of the clamps (16) into the
mounting holes (17).
▪ Use the clamps (16) to fasten the machine onto the
bench.
▪ Tighten the clamps with the wing nuts by hand. Make
sure the clamps are tightened properly but do not over
tighten.
▪ Make sure the machine is securely fastened to the
bench before switching the machine on.
The machine can be set to continuous operation by
means of the lock-on button (4).
MOUNTING THE SANDING FRAME
The wide footprint of the sanding frame enables the en-
tire assembly to glide over uneven surfaces and prevents
sander tilting and gouging.
When flatness is important and the surface is large, like a
floor or a table top, always use the sanding frame.
Put the sanding frame (14) on the machine and insert the
four straps into the slots (13).
(Fig. 10)
Rotate the knurled adjustment bolt at the rear of the
sanding frame (14) to fasten or release the frame. (Fig.11)

Maintenance
WARNING:
Always ensure that the tool is
switched off and unplugged before attempting to per-
form inspection or maintenance. Regularly check that
all the fixing screws are tight. They may vibrate loose
over time.
Re-lubricate all moving parts at regular intervals.
BRUSH REPLACEMENT
When the carbon brushes are worn out, both brushes
must be replaced simultaneously with genuine brushes
at SPARKY service centre for warranty and post-war-
ranty service.
CLEANING
For safe operation always keep the machine and
its ventilation slots clean. Regularly check to see if any
dust or foreign matter has entered the grills near the mo-
tor and around the switches. Use a soft brush to remove
any accumulated dust. Wear safety glasses to protect
your eyes whilst cleaning.
If the body of the tool needs cleaning, wipe it with a soft
damp cloth. A mild detergent can be used.
WARNING:
Never use alcohol, petrol or other
cleaning agent. Never use caustic agents
to clean plastic parts.
