DO support board or
panel NEAR the cut.
SUPPORT
Cutting
Place the wider portion of the saw shoe on that part of the work
piece which is solidly supported, not on the section that will fall off
when the cut is made. As examples, Figure 11 illustrates the RIGHT
way to cut off the end of a board. Always clamp work. Don't try to
hold short pieces by hand! Remember to support cantilevered and
overhanging material. Use caution when sawing material from
below.
Be sure saw is up to full speed before blade contacts material to be
cut. Starting saw with blade against material to be cut or pushed for-
ward into kerf can result in kickback. Push the saw forward at a
speed which allows the blade to cut without laboring. Hardness and
toughness can vary even in the same piece of material, and knotty
or damp sections can put a heavy load on the saw. When this hap-
pens, push the saw more slowly, but hard enough to keep working
without much decrease in speed. Forcing the saw can cause rough
cuts, inaccuracy, kickback, and over-heating of the motor. Should
your cut begin to go off the line, don't try to force it back on. Release
the switch and allow blade to come to a complete stop. Then you
can withdraw the saw, sight anew, and start a new cut slightly inside
the wrong one. In any event, withdraw the saw if you must shift the
cut. Forcing a correction inside the cut can stall the saw and lead to
kickback.
FIG. 13
DON'T support board or
panel AWAY from the cut.
IF SAW STALLS, RELEASE THE TRIGGER AND BACK THE SAW
UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN THE
CUT AND CLEAR OF THE CUTTING EDGE BEFORE RESTART-
ING.
As you finish a cut, release the trigger and allow the blade to stop
before lifting the saw from the work. As you lift the saw, the spring-
tensioned telescoping guard will automatically close under the
blade. Remember the blade is exposed until this occurs. Never
reach under the work for any reason. When you have to retract the
telescoping guard manually (as is necessary for starting pocket
cuts) always use the retracting lever.
NOTE: When cutting thin strips, be careful to ensure that small cut-
off pieces don't hang up on inside of lower guard.
RIPPING (FIG. 14)
Ripping is the process of
cutting wider boards into
narrower strips – cutting
grain lengthwise. Hand
guiding is more difficult for
this type of sawing and the
use of a rip fence is
recommended.
POCKET CUTTING (FIG. 15)
CAUTION: TURN OFF TOOL AND REMOVE BATTERY PACK
FROM SAW BEFORE CHANGING ACCESSORIES OR MAKING
ANY ADJUSTMENTS.
CAUTION: Never tie the blade guard in a raised position. Never
move the saw backwards when pocket cutting. This may cause the
unit to raise up off the work surface which could cause injury.
A pocket cut is one that is made in a floor, wall, or other flat surface.
1. Adjust the saw shoe so the blade cuts at desired depth.
2. Tilt the saw forward and rest front of the shoe on material to be
cut.
