Switch
Release lock off by pressing button as shown (Fig. 10). Pull the trigger
switch to turn the motor ON. Releasing the trigger turns the motor OFF.
Releasing the trigger also automatically actuates lock off button.
NOTE: This tool has no provision to lock the switch in the ON position,
and should never be locked ON by any other means
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. 6 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 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.
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. 9)
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 cutting line until cut is
completed. Release trigger and allow blade to stop completely before
withdrawing the blade from the material. When starting each new cut,
repeat as above. 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 of the work surface which could cause injury.
Cleaning
Use only mild soap and a damp cloth to clean the tool. Many household
cleaners contain chemicals which could seriously damage plastic. Also,
do not use gasoline, turpentine, lacquer or paint thinner, dry cleaning
fluids or similar products. Never let any liquid get inside the tool; never
immerse any part of the tool into a liquid.
