7. REsTARTing A CUT WiTh ThE BlADE TEETh
JAMMED AgAinsT ThE MATERiAl
a. The saw should be brought up to full operating speed
before starting a cut or restarting a cut after the unit
has been stopped with the blade in the kerf. Failure to
do so can cause stalling and kickback.
Any other conditions which could result in pinching, binding,
twisting, or misalignment of the blade could cause kickback.
Refer to the sections Further Safety Instructions for All
Saws and Blades for procedures and techniques that will
minimize the occurrence of kickback.
Cutting Depth Adjustment (Fig. H, I)
1. Hold the saw firmly and loosen (clockwise) the depth
adjustment knob 4 and move shoe to obtain the desired
depth of cut.
2. Make sure the depth adjustment knob has been
retightened (counterclockwise) before operating saw.
For the most efficient cutting action, set the depth
adjustment so that one-half tooth of the blade will project
below the material to be cut. This distance is from the tip of
the tooth to the bottom of the gullet in front of it. This keeps
blade friction at a minimum, removes sawdust from the cut,
results in cooler, faster sawing and reduces the chance of
kickback. A method for checking for correct cutting depth
is shown in Figure I. Lay a piece of the material you plan to
cut along the side of the blade, as shown, and observe how
much tooth projects beyond the material.
Bevel Angle Adjustment (Fig. I)
The full range of the bevel adjustment is from 0 ° to 50 °. The
quadrant is graduated in increments of 1 °. On the front of
the saw is a bevel angle adjustment mechanism consisting of
a calibrated quadrant and a bevel adjustment knob
To Set the Saw for a Bevel Cut
1. Loosen (counterclockwise) the bevel adjustment
knob 10 and tilt shoe to the desired angle by aligning
the pointer with the desired angle mark.
2. Retighten knob firmly (clockwise).
Shoe Adjustment for 90 °Cuts (Fig. J)
If Additional Adjustment is Needed:
1. Adjust the saw to 0 ° bevel.
2. Retract the lower blade guard. Place the saw on
blade side.
3. Loosen bevel adjustment knob
against the blade and shoe to adjust the 90 ° setting.
4. Turn the calibration screw
at the proper angle.
5. Confirm the accuracy of the setting by checking the
squareness of an actual cut on a scrap piece of material.
Kerf Indicator (Fig. K)
The front of the saw shoe has a kerf indicator
and bevel cutting. This indicator enables you to guide the
saw along cutting lines penciled on the material being cut.
The kerf indicator lines up with the left (inner) side of the
saw blade, which makes the slot or "kerf" cut by the moving
10 .
10 . Place a square
19 so that the shoe will stop
9 for vertical
blade fall to the right of the indicator. Guide along the
penciled cutting line so that the kerf falls into the waste or
surplus material.
Workpiece Support (Fig. L–O, Q)

WARNING: It is important to support the work
properly and to hold the saw firmly to prevent loss of
control which could cause personal injury. Figure L, Q
illustrates proper hand support of the saw. Maintain a
firm grip with both hands on the saw and position your
body and arm to allow you to resist kickback if it occurs.
ALWAYS TURN OFF TOOL AND REMOVE BATTERY
BEFORE MAKING ANY ADJUSTMENTS!
Figure L shows proper sawing position. Note that hands are
kept away from cutting area. To avoid kickback, DO support
board or panel NEAR the cut (Fig. N). DON'T support board or
panel away from the cut (Fig. O).
Place the work with its "good" side – the one on which
appearance is most important – down. The saw cuts upward,
so any splintering will be on the work face that is up when
you cut it.
Cutting (Fig. L, M)
Place the wider portion of the saw shoe on that part of the
workpiece which is solidly supported, not on the section
that will fall off when the cut is made. As an example,
Figure L illustrates the RIGHT way to cut off the end of a
board. Always clamp work. Don't try to hold short pieces by
hand! (Figure M) 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 trigger 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. 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 SWITCH 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 switch and allow the
blade to stop before lifting the saw from the work. As you
lift the saw, the spring-tensioned lower blade 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 lower blade guard
