NOTE: This tool has no provision to lock the switch in the ON
position, and should never be locked ON by any other means.

Work Piece Support

FIG. 7 shows proper sawing position. Note that hands are kept away
from cutting area. To avoid kickback, DO support board or panel
NEAR the cut, (FIG. 8). DON'T support board or panel away from the
cut, (FIG. 9).
WARNING: It is important to support the work properly and to
hold the saw firmly to prevent loss of control which could cause
personal injury. FIG. 7 illustrates typical hand support of the saw.
ALWAYS TURN OFF TOOL AND REMOVE BATTERY BEFORE
MAKING ANY ADJUSTMENTS!
Place the work with its "good" side–the one on which appearance is
most important–down. The saw cuts upward, so any splintering will
be on the work face that is up when you cut it.
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, FIG. 7 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
forward 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 happens,
push the saw more slowly, but hard enough to keep it working without
much decrease in speed. Forcing the saw can cause rough cuts,
inaccuracy, kickback, and over-heating of the motor. Should your cut
8:25 AM Page 10
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.
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 RESTARTING.
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 cutoff
pieces don't hang up on inside of lower guard.
RIPPING
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 some type of guide should be used.
POCKET CUTTING (FIG. 10)
TURN OFF TOOL AND REMOVE BATTERY PACK BEFORE
ADJUSTING.
A pocket cut is one that is made in a floor, wall, or other flat surface.
Adjust saw shoe so blade cuts at desired depth. Tilt saw forward
and rest front of the shoe on material to be cut. Using the retracting
lever, retract blade guard to an upward position. Lower rear of shoe
until blade teeth almost touch cutting line. Now release the blade
guard (its contact with the work will keep it in position to open freely
as you start the cut). Start the motor and gradually lower the saw until
its shoe rests flat on the material to be cut. Advance saw along the
