Operating Instructions
Hold the tool with both
hands while starting the
tool, since torque from the motor can cause the
tool to twist.
Start the tool and let the tool come to full
speed before contacting the workpiece. Lift
the tool from the work 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.
SLIDE ON-OFF SWITCH WITH LOCK
The tool is switched “ON” by the switch
button located at the side of the motor
housing. The switch can be locked in the
“ON” position, a convenience for long
grinding operations.
TO TURN THE TOOL “ON” without locking it,
slide the switch button forward by applying
pressure ONLY at the REAR portion of the
button. When pressure is released the switch
button will snap to “OFF” position (Fig. 1).
TO LOCK THE SWITCH “ON”, slide the
switch button forward and press “IN” the
FRONT portion.
TO UNLOCK THE SWITCH, simply press
and release the REAR portion of the button.
Switch is spring loaded and will snap back
automatically.
SELECTING GRINDING WHEELS
Before using a grinding
wheel, be certain that its
maximum safe operating speed is not
exceeded by the nameplate speed of the
grinder. Do not exceed the recom mended
wheel diameter.
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 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 keep ing the angle between 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.
Excessive or sudden
pressure on the wheel will
slow 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 work piece when pushing forward.

WIRE BRUSH ASSEMBLY
B
efore assembling wire brush to this tool,
disconnect from the power source. Attach
hand guard (Fig. 1). Wire brushes are
equipped with their own threaded hub, simply
thread on to spindle. Be sure to seat against
shoulder before turning tool “ON”.
TO REMOVE: Reverse procedure.
WIRE WHEEL ASSEMBLY
B
efore assembling wire wheel to this tool,
disconnect from the power source. Attach type
27 guard (Fig. 2). Wire wheels are equipped
with their own threaded hub, simply thread on
to spindle. Be sure to seat against shoulder
before turning tool “ON”.
TO REMOVE: Reverse procedure.
