7.
Do not pause in any one spot during the sanding operation. The belt will
eat into the work and make the surface uneven.
8.
Lift the tool from the work before turning the motor off.
9.
Always be sure that the motor has completely stopped before putting the tool
down.
FAST SANDING ON ROUGH WORK
To smooth a rough surface quickly,
use a coarse grit abrasive belt. With
the belt positioned diagonally across
the grain, move the tool in the
direction of the grain (Fig. 5)
.
Overlap the strokes and cover the
entire surface, working from both
sides of the board (angle left and
then angle right.) Smooth the
surface by guiding the sander back
and forth with the grain. Change the
belt to a medium grit and follow the
same procedure.
Finish by thoroughly working the grain lengthwise. Change again to a fine grit
and repeat. Always finish sanding with the grain.
REMOVING OLD PAINT AND VARNISH
Read and follow “ADDITIONAL SAFETY RULES FOR
PAINT REMOVAL” section of this manual.
The 352VS is an excellent tool for removing old paint and varnish from flat
surfaces. However, two problems are common: 1) sanding material that loads
the abrasive and, 2) friction heat caused by working too long in one place. To
overcome the loading problem, use a coarse grit open coat abrasive belt and a
single stroke action. Overheating can be avoided by using a fairly quick stroke
and moving to another area quickly. A piece of felt about 1/4" thick can be
inserted under the shoe for fast spot sanding and for working on stubborn
areas of paint and varnish.
SPECIAL SANDING PROCEDURES
Generally, sand with a back and forth motion. Some materials and some types
of operations, however, require a different technique. In rough sanding, use the
tool at an angle. In spot sanding, use the tool with only the front pulley
touching the surface (especially useful in smoothing excess glue from wood
joints). On metals, slate, marble, or plastic materials, sanding can be done in
all different directions because of a lack of grain.
