Hold the tool with both
W RNING
hands while starting the tool,
since torque from the motor can cause the
tool to twist.
Start the tool before applying to work and let
the tool come to full speed before contacting
SELECTING GRINDING WHEELS
Before using a grinding
W RNING
wheel, be certain that its
maximum safe operating speed is not
exceeded by the nameplate speed of the
grinder. Do not exceed the recommended
wheel diameter.
DISC GRINDING WHEELS
Grinding wheels should be carefully selected in
order to use the grinder most efficiently.
Wheels vary in type of abrasive, bond,
hardness, grit size and structure. The correct
type of wheel to use is determined by the job.
Use disc grinding wheels for fast grinding of
structural steel, heavy weld beads, steel
casting, stainless steel and other ferrous
metals.
GRINDING TIPS
Efficient grinding is achieved by controlling the
pressure and keeping the angle between
SELECTING SANDING DISC
Sanding discs are made of extremely hard and
sharp aluminum oxide grits, phenol-resin
bonded to a sturdy fiber backing for fast heavy-
duty service and long life. The discs vary as to
size and spacing of the abrasive grits. OPEN
COAT (type H) — used for soft materials and
on paint or varnish. CLOSED COAT (type K)
—used for metal, hardwood, stone, marble
and other materials.
Operation: Refinishing painted wood or metal surfaces.

before releasing the switch. DO NOT turn the
switch "ON" and "OFF" while the tool is
under load; this will greatly decrease the
switch life.
Grinding Operations
wheel and workpiece at 10° to 15°. If the wheel
is flat, the tool is difficult to control. If the angle
is too steep, the pressure is concentrated on a
small area causing burning to the work
surface.

grinding action and put dangerous stresses on
the wheel.
When grinding with a new wheel be certain to
grind while pulling tool backwards until wheel
becomes rounded on its edge. New wheels
have sharp corners which tend to "bite" or cut
into workpiece when pushing forward.
Sanding Operations
Sanding discs range in grit from 16 (very
coarse) to 180 (very fine). To obtain best
results, select sanding discs carefully. Many
jobs require the use of several grit sizes and at
times both "open coat and closed coat" discs
are required to get the job done faster. See
chart for application examples.
For best results, tilt the Disc Sander at a 10° to
15° angle while sanding so that only about 1"
of the surface around the edge of the disc
contacts the work.
