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
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.

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,

and other ferrous metals.
GRINDING TIPS
Efficient grinding is achieved by controlling the
pressure and keeping 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.
