(figure 4 ). KICKBACK from blade pinch

times.

• STAY ALERT AND EXERCISE
CONTROL. Keep body positioned to one
side of blade. Always maintain a firm grip
and control of saw with both hands. Do
not change hand grip or body position
while saw is running. Take precaution to
avoid injury from cut off pieces and other
falling material during operation.
DANGER: RELEASE SWITCH
IMMEDIATELY IF BLADE BINDS OR
SAW STALLS
GUARD AGAINST KICKBACK
• KICKBACK CAN BE CAUSED BY the
saw blade becoming pinched, twisted or
bound while cutting, or when the saw
stalls. When the blade becomes twisted
or misaligned in the cut, the teeth at the
back edge of the blade can dig into the
top surface of the wood causing the
blade to climb out of the cut and move
suddenly back toward the operator.

TO REDUCE THE RISK OF KICKBACK

• Keep a firm grip on saw with both hands
at all times.
• Stay alert – exercise control.
• Support long overhanging materials. As
the material is cut and weakens, it will
sag, causing a pinched blade.
• Support large panels as shown (Fig. 1).
Material supported only at the ends (Fig.
2) will lead to blade pinching.
• Avoid sawing overhead. Material can
sag and will pinch blade.
• Keep blades sharp and clean.
• Use fence or straight edge guide when
ripping. Be careful as the cut off strip can
sag or twist, closing the cut and pinching

the blade, leading to KICKBACK.
• Don't force tool. Wood variables such as
knots, hardness, toughness, wetness,
pressure treated and freshly cut green
lumber can heavily load the saw which
can lead to stalling. Push the saw slower
when this occurs.
• Don't remove saw from work during a
cut while the blade is moving.
• Allow saw to reach full speed before
blade contacts material to be cut.
Starting the saw with the blade against
the work or pushed forward into cut can
lead to stalling or sudden backward
movement of saw.
• Never attempt to lift saw when making a
bevel cut. This leads to blade binding
and stalling.
• Always secure work to prevent
workpiece movement during cut.
• Do not try to force saw back on line if
your cut begins to go off line. This can
cause KICKBACK. Stop saw and allow
blade to coast down to a stop. Withdraw
from cut and start a new cut on the line.
• Set depth adjustment of saw such that
one tooth of the blade projects below the
workpiece as shown in (figure 8).
• Do not back up a rotating blade in the
cut. Twisting the saw can cause the
back edge of the blade to dig into the
material, climb out of the work and run
back toward the operator.
• Avoid cutting nails. Inspect for and
remove all nails from lumber before
cutting.
