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.
