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 springtensioned 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. 16

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 8 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.
