• Always use blades with correct size and shape (diamond
vs. round) 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 bolts. The
blade washers and bolt were specially designed for your saw, for
optimum performance and safety of operation.
• Avoid cutting nails. Inspect for and remove all nails from lumber
before cutting.
• Do not operate this tool for long periods of time. Vibration
caused by the operating action of this tool may cause permanent
injury to fingers, hands, and arms. Use gloves to provide extra
cushion, take frequent rest periods, and limit daily time of use.
CAUSES AND OPERATOR PREVENTION OF KICKBACK
• Kickback is a sudden reaction to a pinched, bound 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 bound 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 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:
• 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.
• 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.
• When restarting a saw in the workpiece, center the saw blade
in the kerf and check that the 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.
• Support large panels to minimize the risk of blade pinching
and kickback. Large panels tend to sag under their own weight.
Support 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 blade. Unsharpened or improperly
set blades produce narrow kerf causing excessive friction, blade
binding, and kickback.
• Blade depth and bevel adjusting locking levers must be tight
and secure before making cut. If blade adjustment shifts while
cutting, it may cause binding and KICKBACK.
• 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.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber
(CCA).
