Switching on and off

switch the power off.
Attaching a sanding belt
WARNING. Switch off the sander and disconnect it from the
power point.
1. Pull the belt tension release lever (4) and slide off the
old belt.
2. Check that the replacement belt has a good join and is
not frayed at the edges.
3. Slip the new belt into position with the rotation arrow on
the inside of the belt pointing in the same direction as the
arrow on the sander.
Note. When doing this try to place the belt as central as
possible on the front and rear rollers
4. Push the Belt Tension release lever (4) back into place to
tension the belt onto the machine.
5. Before use, the new belt must be checked and aligned
for correct tracking on the rollers. Plug the sander into a
power point and with the sander held tight, press the “I”
switch (1) and allow the belt to rotate for a short period.
6. Whilst the belt is running,
adjust the micro adjustment
knob for belt tracking (3) to
align the belt to the centre of
the front roller (8).
7. Make fine adjustments only
and wait a few seconds
between each adjustment
as there is a short delay in
the response of the adjustment before it effects the belt
tracking on the rollers.
8. Repeat the micro adjustment knob for belt tracking until
the belt is correctly aligned.
9. Run the sander for a minute or so to ensure correct
alignment before using the sander on a work piece.
WARNING. Do not continue to use the sander with a
sanding belt that is overworn or damaged.
WARNING. Do not use a sanding belt designed for sanding
wood on metal. Metal particles become embedded in the
belt and will scour a wooden surface.
Selecting the right grade of sanding belt
Different grades of sanding belt
can be purchased from your
local hardware store. Typical
grades are Coarse (40 grit),
Medium (80 and 100 grit) and
Fine (120 grit).
Use Coarse grade to remove
rough finishes, Medium grade to
smooth the work and Fine grade
to finish it off. It is best 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.
