WARNING! Never use dull or damaged bits. Damaged bits can break without warning.
Dull bits may overload the motor, cut slowly and are difficult to control. They will also
overheat and possibly break.
Operations
1. Before operation:
1) Before turning the tool ON, check to make sure bit and all accessories fasteners are
securely tightened.
2) Avoid cutting your fingers. Make sure all of your fingers are far back from the work-
piece before operation. Keep your hand far away from moving parts.
3) Turn off all circuit breakers and remove all fuses in the work area when cutting into walls
or blind areas.
4) Always set the depth guide to the appropriate depth. Use tool with the depth guide plate
against the work surface for better control of the tool.
5) Before starting the tool, make sure that the bit does not touch the work piece.
6) Before cutting the work-piece, let the tool turn for a while without load.
2. During operation:
1) Always hold the tool with two hands during start-up and operation. When starting, motor
torque will cause the tool to twist.
2) Always make sure the work- piece is free of nails and other foreign objects. If the bit
strikes a nail it will jump sideways and possibly break.
3)
WARNING! Do not attempt to make cutouts around an opening which has live
electrical wires.
If a live wire is contacted, the bit could conduct the electric current to
the tool, creating an electric shock hazard for the operator. Always hold the tool by its
insulated housing when working in area where there is a possibility of contacting electric
wires. Always wear eye protection when operating this tool.
4) When cutting drywall electrical outlet openings, using the outlet as a guide, always cut in
a counter clockwise direction. The natural tendency of the tool to pull to the left will
cause a "hugging” action toward the outlet box, resulting in a neater cut. (Note: Except
for cutting around outlet boxes in drywall, always cut in a clock wise direction).
CAUTION! The fine dust produced by cutting glass-fiber, expended compound
materials, etc., can shorten the tool life.
3. After operation:
1) When the cut is complete, turn the tool OFF, wait until it comes to a complete stop and
remove it from the work-piece.
