VARIABLE SPEED WITH DIAL SETTING
(1703EVS ONLY)
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.

Operating Instructions
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
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)
(1703EVS ONLY)
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
(1703EVS ONLY)
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.
