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
WARNING
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.
CONSTANT RESPONSE CIRCUITRY
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.
SERVICE MINDER™ BRUSHES
Eliminates quess work, stops the tool when
preventive maintenance is required.
