feature which is convenient when sanding for extended

trigger, push in the lock button located on the side of the
handle, then while holding the lock button pushed in, release
the switch tdgger. See Figure 2.
To release the lock, depress the tdgger and release it.

BEFORE CONNECTING TO POWER SUPPLY SOURCE.
DO Nor LOCK THE SWITCH TRIGGER ON JOBS WHERE

PREPARING FOR OPERATION
Forease of operationyour sander has a fronthandic and a rear
handle. These handles allow two-hand operation which aid in

and keepinghands clear of sanding pelt. When operating your
sanderalways holdthe fronthandle with your left hand and the
rear handle with your right hand as shown in Figure 3.
Always operate your sander as shown in Figure 3.
Selecting the correct size gdt and type sanding belt is an
extremely important step in achieving a high quality sanded
finish. Standard 3 in. x 21 in. sanding pelts made of aluminum
oxide, silicon carbide, and other synthetic abrasives are best
for power sanding. Natural abrasives, suchas flintand garnet
are too soft for economical use in power sanding.
In general, coarse gdt sanding halts will remove the most
matedal and finer grit sanding belts will produce the best
finish in all sanding operations. The condition of the surface
to be sanded will determine which gritwill do the job. If the
surface is rough, start with a coarse grit and sand until the
surface is uniform. Medium gdt may then be used to remove
scratches left by the coarser grit and finer gtit used for
finishing of the surface. Always continue sanding with each
grit until sudace is uniform.
