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.

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. 8).
Support the panel or board close to the cut, as
shown in (Fig. 9). 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. 10). Rip Fence is available as an accessory
(not included). To attach fence, insert fence
through slots in foot to desired width as shown
and secure with the wing nut (not included).

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.

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. 11). Use the right
side of the foot against the board guide.
