OPERATING PROCEDURES
DUST BAG
Fit the dust bag over the dust port on the left side of the sander near the rear
handle. Dust extraction is most efficient if the bag is emptied whenever it reaches
half full. Once in a while, it may be beneficent to turn the bag inside out and
thoroughly clean it with a brush.
!
CAUTION: Do not use this sander without some form of dust collection.
SANDING
1. Secure the work piece well. It will tend to move toward the operator while the
sander is running in contact with the surface.
2. Hold the tool firmly with both hands on the hand grips. When the belt comes
in contact with the work surface, the tool will tend to pull itself forward quite
strongly. To prevent damage to the material and the belt, never start the
sander while the belt is in contact with the work surface.
. Turn the tool on and let it come up to speed.
4. Gently lower it keeping the bottom plate roughly parallel with the surface.
5.
contacts the work surface first at the rear, the heel of the sander. Continue to
move the tool forward as you bring the belt into full contact with the surface.
Use only very light downward pressure, if any.
6. Move the tool back. Continue this back and forth motion in overlapping
strokes while sanding. This helps provide an even surface. Avoid putting
weight on the tool as its own weight is usually sufficient. Too much weight can
result in gouging and burning the surface, overloading the motor, and having
the work piece kick back.
7. When sanding a rough wooden surface, placing the sander a slight angle to
the grain, using a coarse grit, while moving the sander itself back and forth
with the grain, may help speed stock removal. The same technique can be
carried on through the medium grits. On the finishing grits, the sander should
be oriented with the grain.
8. When finished sanding, lift the sander off the surface before releasing the
trigger.
NOTE:
 Sanding direction is not critical on most materials other than wood, since
grain direction is not a concern.
 Sanding flush against a perpendicular surface is possible along the right side
of the tool.
Use a grade of sandpaper that will make finer marks than those already on the
surface. Too coarse a grade will not make the surface smoother while too fine a
grade will remove scratches too slowly, or not at all. Continue using finer grades
of sandpaper until you obtain the desired finish.
When removing old paint, determine how much paint really needs to be
removed. Consider that old paint may well be toxic and will have to be treated
with the respect due any toxic material both on the part of the tool operator and
on the part of the environment. Wear appropriate breathing protection and
dispose carefully of dust or chips left after sanding could be tracked throughout
residences and release toxins into the soil. Use the provided dust bag as well.
A finish that is cracking or flaking has to be taken off, but a finish that is still firmly
attached can be "roughed up" and painted over with primer and the new finish.
Always lightly sand the undercoat with fine grade sandpaper before applying the
top coat.
Begin moving the sander forward. Drop the back very slightly so the belt
