Keep hands away from
cutting area and the blade.
Keep your second hand on auxiliary
handle, or motor housing. If both hands
are holding the saw, they cannot be cut by
the blade.
Do not reach underneath the workpiece.
The guard cannot protect you from the
blade below the workpiece.
Adjust the cutting depth to the thickness
of the workpiece. Less than a full tooth of
the blade teeth should be visible below the
workpiece.
Never hold piece being cut in your hands
or across your leg. Secure the workpiece
to a stable platform. It is important to
support the work properly to minimize body
exposure, blade binding, or loss of control.
Hold the power tool by insulated gripping
surfaces only, when performing an
operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with a "live" wire will also make
exposed metal parts of the power tool "live"
and could give the operator an electric
shock.
When ripping, always use track, rip fence
or straight edge guide. This improves the
accuracy of cut and reduces the chance of
blade binding.
Always use blades with correct size and
shape (diamond versus round) of arbor
holes. Blades that do not match the
mounting hardware of the saw will run
eccentrically, causing loss of control.
Never use damaged or incorrect blade
washers or bolt. The blade washers and
bolt were specially designed for your saw,
for optimum performance and safety of
operation.
Inspect the condition and quality of the
wood and remove all nails from lumber
before cutting. Wet lumber, green lumber
or pressure treated lumber require special
attention during cutting operation to
prevent kickback.
Hold the saw firmly to prevent loss of
control. Figures in this manual illustrate
typical hand support of the saw.
Depending upon use, the switch may not
last the life of the saw. If the switch should
fail in the "OFF" position, the saw may not

start. If it should fail while the saw is
running, the saw may not shut off. If either
occurs, unplug the saw immediately and do
not use until repaired.
This circular saw should not be mounted to
a table and converted to a table saw.
Circular saws are not designed or intended
to be used as table saws.
Kickback causes and related
warnings
Kickback is a sudden reaction to a pinched,
jammed or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator.
When the blade is pinched or jammed
tightly by the kerf 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 the operator.
Kickback is the result of saw misuse and/or
incorrect operating
conditions and can be avoided by taking
proper precautions as given below:
Maintain a firm grip with both hands on
the saw and position your arms to resist
kickback forces. Position your body to
either side of the blade, but not in line
with the blade. Kickback could cause the
saw to jump backwards, but kickback forces
can be controlled by the operator, if proper
precautions are taken.
When blade is binding,
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 action to eliminate the cause of
blade binding.
When restarting a saw in the workpiece,
center the saw blade in the kerf so that the
saw teeth are not engaged into the
material. If saw blade binds, it may walk up
or kickback from the workpiece as the saw
is restarted.
