MAKING DRYWALL CUT OUTS
After assembling the bit into the tool as
described earlier, it will be necessary to
review the instructions provided below and
make some practice cut-outs with this tool
before attempting an actual job. The best
method is to take some scrap pieces and nail
or screw them in place over wall studs which
have an electrical box or other feature in
place. A few such exercises will give you the
necessary practice to make clean,
professional cutouts around whatever is
behind the drywall you are installing.
ILLUSTRATED INSTRUCTIONS FOR PERFECT OUTLET
OPENINGS IN DRYWALL
The following procedure will illustrate cutting out a standard 2 1/8" X 3 3/4" electrical box.
MAKE A FEW PRACTICE CUTS
After installing the Zip Bit into the tool and
adjusting your depth guide, you should make
a few practice cuts with the tool before
attempting an actual job.
A few exercises will give you the necessary
practice to make clean, professional cuts.
Step 1: Make certain that the collet nut is
securely tightened before turning the tool on.
Step 2: Hold the tool firmly and turn the tool
ON to your desired speed.
IMPORTANT USER TIP
Step 3: While holding the tool firmly, insert
the Zip Bit into the material at a 45° angle
(Fig. 11).
Step 4: Slowly bring it to a 90° angle to begin
the cut (Fig. 12). The base guide should be
flush to the material surface. For all materials
(EXCEPT cutting around outlet boxes in
drywall), steer the tool in a clockwise
direction with slow, steady pressure to make
the cut.
Step 5: After completing your cut, turn off the
tool and carefully remove it from the material.
Do not attempt to use this tool to make cut-
outs around any fixture or opening which has
live electrical wires, or any wall which may
have live electrical wiring behind it, as the Zip
Bit could conduct current to the tool, creating
an electrocution hazard for the operator.
Shut off breakers or remove fuses to
disconnect the circuit. Always hold the tool
by its thermoplastic housing, and always
wear eye protection when operating a Spiral
Saw power tool.
NOTE: Because of the rotating cutting
action of the Zip Bit, there will be a slight pull
when cutting. The slower you cut, the more
control you have. Excessive pressure or fast
cutting will cause excessive heat and may
shorten the life of the Zip Bit.
NOTE: When cutting on a vertical surface,
avoid ending your cut at the bottom of the
hole. If possible, start and end your cut at
the top so the scrap part will not drop onto
the rotating Zip Bit. Turn the tool off and
remove it from the material.
