Cutting Outlet Openings In Drywall - TACKLIFE PTR01A User Manual

CUTTING TIPS – cont'd
Slower cutting gives you better control. Excessive pressure or fast cutting will increase the 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

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, ear and dust
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.
4. Install the cutting bit, assist handle and freehand cutting guide as outlined in Fig. 1, 2 & 3. Adjust
depth of cut so the bit will protrude 1/8" beyond the thickness of the drywall (Fig. 7).
5. Hold the tool firmly with both hands and turn it ON. Plunge the bit through the drywall at the mark
indicating the centre of the box. See Fig. 10 for cutting pattern.
6. Move the bit slowly to the right until you feel and hear the bit contacting the inside of the box.
7. Pull the bit out far enough to slip it over the edge of the box. Once the bit is outside the box, push
it back to full depth beside the outside edge of the box.
8. Move the tool upward while applying slight pressure toward the centre of the box. When you feel
the bit reach the top right corner of the box, move the tool to the left while applying slight pressure
downward toward the centre of the box.
9. Continue moving the tool around the box in a counter-clockwise direction while maintaining slight
pressure toward the centre of the box. When the box cut out is complete, turn the tool OFF and
remove it from the cut out.
