5. VARIABLE SPEED CONTROL (SEE FIG G)
With the variable speed control, the required
speed can be selected (also while running).
The required speed is dependent on the
material and is to be determined by a practical
trial.
After longer periods of working at low speed,
allow the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.

6. USING THE SANDER (SEE FIG. H)
Guide your sander parallel to the working
surface and move it in circles or in a cross
pattern. Do not tilt the tool in order to avoid
deep unwanted sanding marks. The amount of
material removed is determined by the speed
of the sanding disc and the grit size used. The
speed of the sanding disc diminishes relative
to the pressure applied to the tool. For faster
removal, do not increase pressure on the tool,
but use a coarser grit size.

7.SELECT THE RIGHT SAND PAPER
Selecting the correct grit of sandpaper is an
extremely important decision that will allow you
to achieve the best quality sanding nish.
Coarse grit will remove the most material
and ner grit will give you the best nish in all
sanding operations. The condition of the surface
to be sanded will determine which grit will do
the job.
If the surface is rough:
Start with coarse grit (sold separately) and sand
until the surface is uniform. Then use medium
to remove any scratches left by the coarse grit.
Then use ner grit (sold separately) for nishing
the surface.
NOTE: Always continue sanding with each grit
until the surface is uniform.
