SERVICE
• Tool service must be performed only by qualified personnel. Service or maintenance
performed by unqualified personnel could result in risk of injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
WARNING: For your safety, do not plug in your cut out tool or install a bit or
attachment until you have read and understood this Owner’s Manual.
• Wear eye protection. Use face or dust mask along with safety goggles if operation is
dusty. Use hearing protection, particularly during extended periods of operation.
• Do not wear gloves, neckties or loose clothing.
• Do not drill, cut or sand material that is too small to be securely held.
• Always keep hands out of the path of the bit. Avoid awkward hand positions where your
hand could move into the path of the bit.
• Secure workpiece. Use clamps or a vice to hold the work when practical. Use both hands
to guide the tool.
• Make sure there are no nails or foreign objects in the part of the workpiece to be cut, drilled
or sanded.
• Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live” and shock the operator.
• Always make sure the work surface is free from nails and other foreign objects.
Cutting into a nail can cause the bit and the tool to jump and damage the bit.
• Always use a safe method to secure the workpiece, and use both hands to guide the
tool. Never place hands near or below the cutting surface.
• Never lay workpiece on hard surfaces like concrete, stone, etc. Protruding cutting bit
may cause tool to jump.
• Always wear safety goggles and dust mask. Use only in well-ventilated area. Using
personal safety devices and working in a safe environment reduces risk of injury.
• After changing the bits or making adjustments, make sure the collet nut and any
other adjustment devices are securely tightened. Loose adjustment devices will be
violently thrown.
• Never use dull or damaged bits. Sharp bits must be handled with care. Damaged bits
can snap during use. Dull bits require more force to push the tool, possibly causing the bit to
break.
• Never touch the bit during or immediately after use. After use the bit is too hot to be
touched by bare hands.

7. Turn the switch ON.
8. When the motor is up to full speed, slowly tip the tool to an upright position, letting the bit
cut into the workpiece (Ill. 9). Once the tool has reached the upright position and the bit
has cut through the workpiece, slowly move the tool in a clockwise direction using slow
steady pressure to make the cut.
NOTE: Except for cutting around outlet boxes in drywall, always cut in a clockwise
direction.
9. When cut is complete, turn the tool OFF, wait until it comes to a complete stop and remove
it from the workpiece.
DANGER: Do not attempt cutting around outlet boxes in drywall until:
1. All electricity in the vicinity of electric wires has been disconnected by either turning the
breaker OFF or removing the fuses.
2. You have read the instructions on the following page entitled “CUTTING OUTLET
OPENINGS IN DRYWALL”.
Cutting tips
The rotating cutting action of the bit will cause a slight pull to the left when cutting. Natural
variations in the structure of wood will cause the bit to “wander”. This tendency will be
magnified when applying too much pressure to the bit. Slower cutting gives you better
control. Excessive pressure or fast cutting will increase bit temperature and shorten the life of
the bit.
When cutting a hole in a vertical surface, avoid ending the cut at the bottom of the hole. Always
start and end the cut at the “top” so the cut-out part will not drop onto the rotating bit. Always
turn the tool OFF before removing it from the workpiece
Cutting outlet openings in drywall
Ill.10+11
DANGER: Do not attempt to use this tool to make cut-outs around any fixture or
opening which has live electrical wires or on any wall which may have electrical
wiring behind it. If a live wire is contacted, the bit could conduct the electric current
to the tool, creating an electrocution hazard for the operator. Turn OFF breakers or
remove fuses to disconnect the electric circuit in the area of work. Always hold the
tool by its insulated housing when working in areas where there is a possibility of
contacting electric wires. Always wear eye protection when operating this tool.
1. Before installing drywall, push the electrical wires to the back of the outlet box as far as
possible so they will not be cut by the bit when cutting the opening.
2. Before fastening the drywall sheet over the electrical box, mark the sheet as close as
possible to the centre of the box opening. Mark should be on the side of the drywall facing
you.
3. When fastening the drywall in place, do not place nails or screws closer than 12” from the
box. This will prevent the drywall from becoming deformed under pressure.
