OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
Proper Hand Position (Fig. M)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the main handle
with the other hand on the auxiliary handle
Switching On and Off (Fig. A)

To run the tool, press the trigger switch
trigger switch is released, the lock-off switch is automatically
activated to prevent unintended starting of the machine.
NOTICE: Do not switch the tool ON or OFF when the saw
blade touches the workpiece or other materials.
Workpiece Support (Fig. N–Q)

WARNING: To reduce the risk of serious personal
injury, support the work properly and hold the saw
firmly to prevent loss of control.

cutting area, and power cord is positioned clear of the cutting
area so that it will not get caught or hung up on the work.
To avoid kickback, ALWAYS support board or panel NEAR the
cut, (Fig. N and P). DON'T support board or panel away from the
cut (Fig. O and Q). When operating the saw, keep the cord away
from the cutting area and prevent it from becoming hung up on
the work piece.
ALWAYS DISCONNECT SAW BEFORE MAKING ANY ADJUST-
MENTS! Place the work with its "good" side—the one on which
over
appearance is most important—down. The saw cuts upward,
so any splintering will be on the work face that is up when you
saw it.
Cutting

WARNING: Never attempt to use this tool by resting it
upside down on a work surface and bringing the material
to the tool. Always securely clamp the workpiece and
bring the tool to the workpiece, securely holding the tool
with two hands as shown in Figure P.
Place the wider portion of the saw foot plate 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 P
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
2 ,
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.
