•If you do rough sanding use sanding belt with grain size between 40 - 60. For fine sanding work or
polishing use smaller grain size belt (60 and above). See the chart above. If the surface of the work piece
is not evenly flat, use hard sanding belt to flatten the surface first. For finishing use fine grain sanding belt.
Fixing the sanding belt in place
•Warning: Before putting the sanding belt on,
make sure the power cable is disconnected from
the wall outlet and the main switch/trigger is off.
•Pull the handle to release the belt-tensioning
device.

arrow on the back side of the sanding belt
points in the same direction as the arrow on the
machine to ensure the correct turning direction.
•When the belt is fixed in place, return the handle
back to its original position.

•Make sure that the sanding belt is parallel with
the surface of the work piece. Hold both the real

for even sanding. Excessive pressure on your
machine during work slows down the revolutions
of the belt, may damage the engine, the work piece
or vital parts of your sanding machine.
