OPERATION cont.
1. ALWAYS maintain a firm grip with both
(see Fig. 7) hands on the saw and
position your body and arms to allow you
to resist Kickback forces. Kickback forces
can be controlled by the operator, if the
proper precautions are taken.
2. If the blade is binding, or when you are
interrupting a cut for any reason,
ALWAYS release the trigger and hold the
saw motionless in the material until the
blade comes to a complete stop. NEVER
attempt to remove the saw from the work
or pull the saw backward while the blade
is in motion, or Kickback may occur.
CHECK and take corrective action to eliminate the cause of blade binding.
3. Inspect the workpiece for knots or nails before cutting. Never saw into a knot or nail.
4. DO NOT cut warped or wet lumber. (see Fig. 6a)
5. ALWAYS support large panels to minimize the risk of blade pinching and Kickback.
Large panels tend to sag under their own weight (see Fig. 6a). Supports MUST be
placed under the panel, one near the line of cut and one near the edge of the panel
(see Fig. 6).
6. When restarting the saw in the workpiece, CENTER the blade in the kerf and check to
be sure that the saw teeth are not engaged into the material. If the saw blade is binding,
it may walk up or Kickback from the workpiece when the saw is restarted.
7. DO NOT use a dull or damaged blade. Unsharpened, improperly set, or gummed-up
blades produce narrow kerf which causes excessive friction, blade binding and Kickback.
8. KEEP the blade at the correct depth setting. The depth setting should not exceed
1/4-inch below the material being cut (see Fig. 5). BE SURE that the blade depth and
adjusting locking levers are tight and secure BEFORE making a cut. If blade adjustment
shifts while cutting it may cause binding and Kickback.
9. USE EXTRA CAUTION when making a “Pocket Cut” into existing walls or other blind
areas. The protruding blade may cut objects that can cause Kickback.

DANGER:
Ways to Help Prevent Kickback
Fig. 7
ALWAYS release trigger switch immediately if the blade binds
or the saw stalls. Kickback could cause you to lose control of the saw. Loss of
control can lead to serious injury.

OPERATION cont.
WARNING: ALWAYS unplug saw before making any adjustments. Failure
to unplug the saw could result in accidental starting which can cause serious
personal injury.

TO SET THE BLADE DEPTH (Fig. 8a)
2. Raise the depth-of-cut adjustment
lever to loosen the base (see Fig. 8).
3. Determine the desired depth of cut.
4. Locate the depth-of-cut scale on the
back of the upper blade guard
(see Fig. 8a).
5. Hold the base of the saw flat against
the edge of the workpiece and then
raise or lower the saw until the indicator
mark on the bracket aligns with the
notch on the blade guard at
the desired depth-of-cut mark.
6. Tighten depth-of-cut adjustment lever.

MAKING DEPTH-OF-CUT ADJUSTMENTS (Fig. 8)
ALWAYS use the correct blade depth setting. The correct blade depth setting for all cuts
should not be more than 1/4-inch below the material being cut (see Fig 5). Allowing more
depth will increase the chance of kickback and cause the cut to be rough. Your saw is
equipped with a depth-of-cut scale that provides increased depth-of-cut accuracy.
The depth-of-cut scale is located on the inside back of the upper blade guard.
