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.
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 live electrical wiring behind it, as
the 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 this device.

MAKE A FEW PRACTICE CUTS
After installing the 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.
Step 3: While holding the tool firmly, insert the
bit into the material at a 45° angle (Fig. 9).
Step 4: Slowly bring it to a 90° angle to begin
the cut (Fig. 10). 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 cutouts
around any fixture or opening which has live
electrical wires, or any wall which may have
live electrical wiring behind it, as the 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 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 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 bit. Turn the tool off and remove it
from the material.
