Kickback causes and related warnings
KICKBACK is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an un-
controlled saw to lift up and out of the workpiece
toward the operator.
When the blade is pinched or bound tightly by the
kerf, or cutting slot, closing down, the blade stalls
and the motor reaction drives the unit rapidly back
toward the operator.
If 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 kerf and jump back toward operator.
KICKBACK is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
1. Maintain a firm grip with both hands on the
saw and position your body and arm to allow
you to resist KICKBACK forces. KICKBACK
forces can be controlled by the operator, if proper
precautions are taken.
2. When blade is binding, or when interrupting
a cut for any reason, 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. Investigate
and take corrective actions to eliminate the cause
of blade binding.
3. When restarting a saw in the workpiece,
center the saw blade in the kerf, or cut, and
check that saw teeth are not engaged into the
material. If saw blade is binding, it may walk up
or KICKBACK from the workpiece as the saw is
restarted.
4. Support large panels to minimize the risk of
blade pinching and KICKBACK. Large panels
tend to sag under their own weight. Supports
must be placed under the panel on both sides,
near the line of cut and near the edge of the
panel.
5. Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding and
KICKBACK.
6. Depth adjusting lever must be tight and se-
cure before making cut. If blade adjustment
shifts while cutting, it may cause binding and
KICKBACK.
7. 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.
8. Set the depth of cut for no more than 1/4"
greater than the thickness of the stock. The
less blade exposed, the less chance of binding
and KICKBACK. Before cutting, be sure depth
and bevel adjustments are tight.
9. Stay alert. Any distraction can cause twisting
or binding. Repetitive cuts may lull the user into
careless movements.
Warning
everyone in the work area should wear safety
goggles or glasses with side shields. Unplug
the tool before changing accessories or mak-
ing adjustments.
General Operation
Always clamp the workpiece securely on a saw
horse or bench. See "Applications" for the correct
way to support your work in different situations.

1. Draw a cutting line. Place the front of the shoe on
the edge of the workpiece without making blade
contact. Hold the trigger handle with one hand
and the front handle with the other.
Fig.3
2. Line up the sight line with your cutting line. Posi-
tion your arms and body to resist KICKBACK.
3. Pull the trigger and allow the motor to reach full
speed before beginning cut.
4. While cutting, keep the shoe flat against the
workpiece and maintain a firm grip. Do not force
the saw through the workpiece. Forcing a saw
can cause KICKBACK. Use a light, continuous
pressure to make the cut while following the cut
line through the sight line.
5. If making a partial cut, restarting in mid-cut or
correcting direction, allow the blade to come to
a complete stop. To resume cutting, center the
blade in the kerf, back the saw away from cutting
edge a few inches, pull the trigger and re-enter
the cut slowly.
6. If the saw binds and stalls, maintain a firm grip
and release the trigger immediately. Hold the
saw motionless in the workpiece until the blade
comes to a complete stop.
7. After finishing a cut, be sure the lower guard
closes and the blade comes to a complete stop
before setting the saw down.
