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.
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.
Hold the tool with both

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

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.

Operating Instructions
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.
ELECTRONIC FEEDBACK CIRCUITRY (EFC)
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.
OVERLOAD PROTECTION
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.
Grinding Operations
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.
WARNING
!
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.
