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 sanding and polishing 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 ! WARNING 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.
