OPERATION
WARNING:
To avoid possible serious injury, never use saw
when the guard system and return spring are not
operating correctly. Check the guard for correct
operation before each use. If you drop the saw,
check the guard for damage at all depth settings
before reuse. If the guard system does not retract
the blade into the upper guard, take the saw to an
authorized factory service center for repair before
continuing use.
If at any time the riving knife or blade does not return to
inside the guard, remove the battery from the saw. Exercise
the plunge motion by pressing the lock off button and mov-
ing it rapidly back and forth through the full plunge depth
several times. Normally this will restore the knife and blade
to its normal operating condition. If it does not correct, do
not use the saw. Take it to an authorized factory service
center for repair.
LOCK-OFF BUTTON
See Figure 18, page 21.
The lock-off button reduces the possibility of accidental
starting. The lock-off button is located on the handle above
the switch trigger. The lock-off button must be depressed
before you pull the switch trigger. The lock resets each time
the trigger is released.
When the saw is raised to its uppermost position it will be
locked in that position. Depress the lock-off button to unlock
the saw.
STARTING/STOPPING THE SAW
See Figure 18, page 21.
WARNING:
Always check that the spindle lock button is fully
released before switching on the tool.
To start the saw:
 Install the battery pack.
 Depress the lock-off button.
 Depress the switch trigger.
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 or plunging the saw too
quickly into the workpiece could cause the saw to
"kickback" towards you resulting in serious injury.
Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
To stop the saw: release the switch trigger.
After you release the switch trigger, allow the blade to come
to a complete stop. Slowly allow the front handle to rise until
the blade is completely inside of the guard and the saw is
in the locked position. Do not remove the saw from the
workpiece while the blade is moving.
USING THE TRACK
See Figures 19 - 26, pages 21 and 22.
The saw can be used with or without a track. To use the
saw with a track, secure the track to a workpiece then at-
tach the saw to the track. If you are using multiple tracks,
assemble and secure the tracks together as described in
the Assembly section.
WARNING:
When cutting along multiple tracks, always ensure
the tracks are properly aligned and assembled.
Cutting along incorrectly assembled or misaligned
tracks could cause the saw to move in unexpected
ways which may result in serious injuries or prop-
erty damage.
To trim the rubber cut strip on the tracks:
 Remove the battery pack.
 Place scrap material onto a workbench, table or other
suitable support. The material should be as long or longer
than the tracks being prepared for use.
NOTE: Each track is 27.5 inches long.
 Place the track on the scrap material.
 Use the track clamp to secure the track and scrap mate-
rial to the support.
 Align the slot in the saw's base with the raised rail on the
track. Then, lower the saw onto the track.
 Check for play at the front and back of the saw and ensure
the saw glides along the track smoothly.
 If necessary, rotate the track adjustment knobs until all
play (left and right) is eliminated and the saw moves freely
(forward and back).
 Set the depth of cut to score depth (1/8 in) with the depth
of cut button.
 Reinstall the battery pack.
 Slide the saw to the starting end track and ensure the
blade is positioned to cut all the rubber.
 Start the saw and let the blade reach full speed.
 Carefully lower the blade until it contacts the workpiece.
 Guide the saw in a forward direction along the track to
trim the rubber cut strip.
NOTE: After the rubber cut strip is trimmed, it can be
used to accurately indicate the blade cut line.
