OPERATION (cont.)
9
Tracking Adjustment
Turn the sander upside down and hold it firmly with one
hand. Press the on/off switch (2) to start the power and
observe the tracking of the sanding belt. If the belt runs
outward, turn the belt tracking adjustment knob (6)
clockwise. If the belt runs inward turn the belt tracking knob
(6) counter clockwise (Fig.10).
Adjust the belt until the outer edge of the belt is even with
the outer edge of both front and rear rollers (Fig. 8,10).
Make sure the belt does not rub against the rear guide
strip (11). Once the belt stabilizes you can begin operation.
Always check your belt after it has been in use as it may
need readjusting.
Timber Sanding
Prior to running the sander ensure you have a firm grip on the rear handle and that
the sanding belt is not in contact with the workpiece.
Note:
Never start the sander with the sanding belt in contact with the work piece.
To commence sanding gently place the rear heel of the
belt sander (See Fig. 11) on your workpiece. Ensure
that the sanding belt is not in contact with your
workpiece prior to starting the sander. Switch the
sander on and in a forward motion, begin the sanding
strokes as the machine is lowered onto the work surface
as this helps and prevents gouging. Keep the sander
moving so that your work will be smooth and even. The
Stroke is simply a back and forth movement with most of the sanding done on the
pull (back) movement. Don’t apply a lot of pressure on the unit allow the sander to
do the work.
Note:
Apply firm even pressure when sanding excessive pressure can damage the
workpiece and sander. Excessive pressure can also cause the belt to "track off".
Take care to select the correct belt for the correct job. For initial smoothing of
rough timber, use course or very course grit and sand with the grain. On very
uneven surfaces or hardwood, sand across the grain. Be careful to avoid gouging.
Then switch to a medium grit belt and sand with the grain. This will provide a
relatively level and smooth finish. Insert a fine belt for final finishing. Always sand
with the grain to remove scratches left by coarser belts. Keep the sander moving in
long, light strokes during finishing operations. As a final touch, experienced
sanders will often insert a “used” fine belt to provide a smooth surface before
filling, sealing, brushing or spraying.
Note:
It is best to try on a sample piece of timber prior to using on project/workpiece.
