• Put a new sanding belt on the machine, make
sure that the direction arrows on the sanding
belt are pointing in the same direction as the
direction indicator (5).
• Fasten the sanding belt fastener again (4).
Aligning the sanding belt
Fig. B
If the sanding belt doesn't run parallel with the
outer edge of the housing, the sanding belt must
be aligned. Move the sanding belt in the correct
position with the adjusting knob (12). By turning
the adjusting knob clockwise the sanding belt will
move to the inside and by turning anti-clockwise
the sanding belt will move to the outside.
Switching on and off
Fig. B
• To switch the machine on press the on/off
switch (7).
• To switch the machine off release the on/off
switch.
If continuous operation is required the
blocking switch (8) must be used:
• Switch the machine on to press the on/off
switch.
• Press the blocking switch and release the on/
off switch.
• To switch the machine off press the on/off
switch again and release the on/off switch.
Setting the speed
Fig. B
The speed adjustment wheel is used for setting
the speed. The speed adjustment wheel can be
set to 6 positions. The ideal speed depends on
the required grain size and on the material to be
worked.
Do not set the speed during use.
• Turn the speed adjustment wheel (6) to the
required position.
- For hard materials, use a sanding belt with
a fine grain size and select a lower speed.
- For soft materials, use a sanding belt with a
coarse grain size and select a higher speed.
• After working for longer periods at low speed
you should allow the machine to cool down by
running it at maximum speed with no-load for
approx. 3 minutes.

Mounting dustbag
Fig. B
A complete dust bag is enclosed. Put the wire-
bracket (inside the dust bag) into to the adapter of
the dust bag (when not mounted). The end of the
bracket has to point upwards. Use the dust bag to
collect dust which is released during sanding.
• Put the dust bag on the dust collection
opening
• Empty the dust bag regularly in order to obtain
an efficient dust extraction.
Grip
The use of the belt sander is made easier
because of the two grips one on the front side
and one on the back. Through that you can hold
the machine with two hands, you have a better
control of the machine and there is less risk to
becoming in touch with the moving parts.
Hold the belt sander always with both hands.
Operating instructions
Make sure that the machine has reached its full
speed before placing the machine on the work
piece. This will prevent an overload of the
machine.
For sanding wood, place the machine
approximately 15° out of the grains of the wood.
Move the belt sander continuous over the work
piece.
• Do not bend the sanding belts
• Do no use the same sanding belt for sanding
wood and metal
• Do not bring too much pressure to your
machine, this will only delay the sanding.
Stationary use
Fig. D
This machine can also be mounted to a worktable
for use as a stationary machine.
• Place the rubber mat on the table as indicated
with the markings. Never mount the machine
onto the table, for stationary use, without the
rubber mat.
• Turn the machine upside down and centre it
on the rubber mat. The mounting holes have
to be facing the front.
• Insert the 2 mounting pins fully in the 2
mounting holes (14)
• Use the brackets to clamp the machine onto
the table.
