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.
!WARNING 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
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
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.
