If at any time the lower blade guard does not snap closed,
unplug the saw from the power supply. Exercise the lower
guard by moving it rapidly back and forth from the full open
position to the closed position several times. Normally this
will restore the guard to its normal operating condition. If
it does not correct a slow or sluggish closing lower guard,
do not use the saw. Take it to an authorized factory service
center for repair.
STARTING/STOPPING THE SAW
See Figure 9, page 17.
To start the saw: depress the switch.
Always let the blade reach full speed, then guide the saw
into the workpiece.
WARNING:
The blade coming in contact with the workpiece before
it reaches full speed could cause the saw to "kickback"
towards you resulting in serious injury.
To stop the saw: release the switch.
After you release the switch, allow the blade to come to a
complete stop. Do not remove the saw from the workpiece
while the blade is moving.
ADJUSTING BLADE DEPTH
See Figure 10, page 17.
Always keep correct blade depth setting. Less than a full tooth
of the blade teeth should be visible below the workpiece.
More blade depth will increase the chance of kickback and
cause the cut to be rough. For more depth of cut accuracy,
a scale is located on the upper blade guard.
To adjust the blade depth:
 Unplug the saw.
 Loosen depth lock lever on back of saw.
 Determine the desired depth of cut.
 Locate depth of cut scale and index point on back of
upper blade guard.
 Hold base flat against the workpiece and raise or lower
saw until the index point (or reference mark) on bracket
aligns with notch on blade guard.
 Tighten depth lock lever securely.
LENGTH OF CUT SCALE
See Figure 11, page 17.
The saw is equipped with a length of cut scale on its base.
It is parallel with the saw blade and can be used to measure
the distance into the material the blade cuts.
NOTE: Six inches is the maximum length of cut that you can
measure. Also, it is accurate only when the depth of cut is
set at full maximum depth.
OPERATION
USING THE LASER GUIDE
See Figure 12, page 17.
WARNING:
Do not stare into the laser beam or turn the laser on when
the tool is not in use. Failure to heed this warning could
result in possible serious personal injury.
The laser unit comes from the factory already installed and
aligned. If the laser becomes misaligned after time refer to
the Adjustments section.
NOTE: Make a trial cut on a piece of scrap to ensure laser
is aligned. Adjusting the laser may be necessary.
 Mark the line to be cut on the workpiece.
 Adjust the depth and angle of the cut as needed and lock
the depth and bevel settings.
 Connect the saw to a power supply.
 Depress the switch to start the motor. The laser guide will
turn on when the switch is depressed and turn off when
the switch is released.
NOTE: Do not touch the blade to the workpiece until the
saw has reached maximum speed.
 Slowly push the saw forward into the workpiece.
NOTE: Keep the laser beam on the marked line on the
workpiece for precision cutting.
 Once the cut is complete, allow the saw to come to a
complete stop. The laser will turn off when the switch is
released.
OPERATING THE SAW
See Figures 13 - 15, pages 17 - 18.
It is important to understand the correct method for operating
the saw. Refer to the figures in this section to learn the correct
and incorrect ways for handling the saw.
WARNING:
To make sawing easier and safer, always maintain proper
control of the saw, by holding the saw with both hands.
Loss of control could cause an accident resulting in
possible serious injury.
DANGER:
When lifting the saw from the workpiece, the blade is
exposed on the underside of the saw until the lower blade
guard closes. Make sure the lower blade guard is closed
before setting the saw down.
