PLUNGE CUTS
Disconnect battery pack from tool before
making adjustments. Set depth adjustment
according to material to be cut. Tilt saw
forward with cutting guide notch lined up with
the line you've drawn. Raise the lower guard,
using lift lever and hold the saw by the front
and rear handles (Fig. 10).
With the blade just clearing the material to be
cut, start the motor. Gradually lower the back
end of saw using the front end of the foot as
the hinge point. WARNING: As blade starts
cutting the material, release the lower
guard immediately. When the foot rests flat
on the surface being cut, proceed cutting in
forward direction to end of cut. WARNING:
Allow blade to come to a complete stop
before lifting the saw from cut. Also, never
pull the saw backward since blade will
climb out of the material and KICKBACK
will occur. Turn saw around and finish the cut
in the normal manner, sawing forward. If
corners of your pocket cut are not completely
cut through, use a jigsaw or hand saw to finish
the corners.
CUTTING LARGE SHEETS
Large sheets and long boards sag or bend,
depending on support. If you attempt to cut
without leveling and properly supporting the
piece, the blade will tend to bind, causing
KICK-BACK and extra load on the motor (Fig. 11).
Support the panel or board close to the cut, as
shown in (Fig. 12). Be sure to set the depth of
the cut so that you cut through the sheet or
board only and not the table or work bench.
The two-by-fours used to raise and support
the work should be positioned so that the
broadest sides support the work and rest on
the table or bench. Do not support the work
with the narrow sides as this is an unsteady
arrangement. If the sheet or board to be cut is
too large for a table or work bench, use the
supporting two-by-fours on the floor and
secure.

RIP CUTS
The combination blade provided with your saw
is for both cross cuts and rip cuts. Ripping is
cutting lengthwise with the grain of the wood.
Rip cuts are easy to do with a rip fence
(Fig. 13). To attach fence, insert fence through
slots in foot to desired width as shown and
secure with the knob.

RIP BOARD GUIDE
When rip cutting large sheets, the rip fence
may not allow the desired width of cut. Clamp
or nail a straight piece of 1" (25 mm) lumber to
the sheet as a guide (Fig. 14). Use the right
side of the foot against the board guide.
