The internal electronic feedback system
provides a "soft start", which will reduce the
stresses that occur from a high torque start.
The system also helps to keep the no load
speed virtually constant between no-load
and load conditions.

Your tool is equipped with a kickback stop
feature. This feature shuts of the tool
automatically if the tool stalls, or the wheel
encounters excessive force. To resume
operation, TURN ON/OFF SWITCH TO THE
OFF POSITION, THEN RESTART THE TOOL.

The restart protection feature was designed
to help prevent accidental startups after the
power has been interrupted. To resume
operation if this occurs, TURN ON/OFF
SWITCH TO THE OFF POSITION, THEN
RESTART THE TOOL.

Your tool is equipped with overload
protection to protect the motor. If the tool
stops during operation TURN OFF SWITCH
IMMEDIATELY and allow the motor to cool
for about 30 seconds by running at no-load.
If the overload protection stops the tool
repeatedly, excessive force is causing the
tool to overload. Don't press so hard and let
the tool do the work.

Your tool is also equipped with a variable
speed dial. The grinder’s RPM can be preset
from zero to maximum nameplate rated RPM
by rotating the dial on the motor housing. If
tool is running at a set speed for extended
periods of time, it may be necessary to run
the tool at no- load full speed to cool the motor.

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 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.
!# "
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 pres-
sure 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
