Cuts." Raise lower guard by Retracting Lever. As soon as blade enters the material, lower guard must be
released. For all other sawing, the lower guard should operate automatically.
• Always observe that the lower guard is covering the blade before placing saw down on bench or floor.
An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is released.
• NEVER hold piece being cut in your hands or across your leg. It is important to support the work properly to
minimize body exposure, blade binding, or loss of control.
• Hold tool by insulated gripping surfaces 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 tool "live" and
shock the operator.
• When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the
chance for blade binding.
• 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.

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.
a. 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.
b. 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.
c. 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.
d. 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.
e. Do not use dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf causing
excessive friction, blade binding, and KICKBACK.
f. 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.
g. 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.
