greater than the tool's speed rating. Only
knotted wire wheels can be used with the
Type 27 guard as the crimped wire wheels will
not fit in the guard.
WIRE BRUSH ASSEMBLY
Before 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.

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
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.
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.
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 keep ing the angle between wheel

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.
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.
