3. OPERATION
NOTE: After sanding with a belt sander, an orbital sander should be used to
give a better surface finish.
PRE-SELECTING THE BELT SPEED
The necessary belt speed can be pre-selected with electronic regulator thumbwheel
(12), even during operation.
The optimum belt speed depends on belt grit and processed material and can be
determined through experience.
SANDING
1. These sanders are designed for sanding wood, metal, plastic and similar
materials. They are used mainly for quickly removing a large amount of material.
Do not use these sanders for sanding magnesium.
2. Ensure that the belt is in good condition.
3. Plug in the tool to the power socket.
4. Adjust the necessary speed by rotating the regulator thumbwheel (12).
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.
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 moving 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 box (3) onto the dust extraction port (11).
3. Before removing the dust box, first disconnect the plug from the power supply.
WARNING: For optimum dust removal, empty the dust box 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 box:
remove the dust box and carefully open it, shake the dust and
close the dust box
.
4. A vacuum cleaner adapter can be used to connect a household vacuum cleaner
or workshop dust extraction system to the sander.
5. An adapter is fitted into the dust extraction port (11).

STATIONARY USE
This machine can be mounted to a bench for stationary use.
•
Turn the machine upside down. The mounting holes (14) shall face towards the
operator.
•
Insert the mounting pins of the clamps (13) into the mounting holes (14).
•
Use the clamps (13) 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).

The vibration emission level given in this information sheet has been measured in
accordance with a standardised test given in EN 62841 and may be used to
compare one tool with another. It may be used for a preliminary assessment of
exposure.
The declared vibration emission level represents the main applications of the tool.
However if the tool is used for different applications, with different accessories or
poorly maintained, the vibration emission may differ. This may significantly increase
the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account
the times when the tool is switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level over the total working
period.
