3. Never hold the workpiece in your hands or across your
leg while cutting. 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.
4. Hold the power tool by insulated gripping surfaces, when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a“live" wire will also make exposed
metal parts of the power tool“live" and could give
the operator an electric shock.
5. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of
cut and reduces the chance of blade binding.
6. 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 off-centre. causing loss of control.
7. 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.
KICKBACK CAUSES AND RELATED WARNINGS
1. 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.
2. 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.
3. 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 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 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.
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 so that the saw
teeth are not engaged into the material.
If a saw blade binds, 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.

.
Do not use dull or damaged blades.
Unsharpened
or improperly set blades produce narrow
kerf caus-ing
excessive friction, blade binding and kickback.
