FLUSH SANDING
Your sander has been designed to allow
convenient flush sanding on the right side of
the sander.
Sanding Tips
TECHNIQUE
Grasp the handles firmly. Start the sander with
the belt off the work (NOTE: never start or stop
the tool with the belt in contact with the work
surface). Place the heel of the sander on the
work first. Then, with a forward motion, begin
the sanding stroke as the machine is lowered
onto the work surface. This will prevent
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 movement. Use a
light touch. The weight of the belt sander is the
only pressure required. Too much pressure will
slow the work by overloading the motor and
reducing belt speed. The result will be
decreased sanding efficiency. Sand slowly and
systematically and, when you stop, lift the
sander from the surface before stopping the
tool.
WOOD FINISHING
Take care to select belts wisely. For initial
smoothing of rough lumber, use coarse or very
coarse grit and sand with the grain. On very
uneven or hard wood, sand diagonally (across
the grain). Be careful to avoid gouging. Now
switch to medium grit belt and sand with the
grain. This will provide a relatively level and
smooth finish. Now insert a fine grit 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 for filling,
sealing, brushing or spraying.
REFINISHING COATED WOOD
Your belt sander will also help remove old
paint, varnish or lacquer; however, if the
coating consists of several layers, remove as
much as possible with a paint solvent or
varnish remover before using the belt sander.
Use a hand scraper to remove the residue left
by the solvent and allow surface to dry
completely before sanding.
