FUNCTION OF THE LOWER GUARD:
• Check lower guard for proper closing before each use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is
accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make
sure it moves freely and does not touch the blade or any other part, and all angles and depths of cut.
• Check the operation of the lower guard spring. If the guard and the spring are not operating properly,
they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
• Lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound
cuts”. Raise lower guard by retracting handle and as soon as blade enters the material, the 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 for the blade to stop after switch is released.
KICKBACK CAUSES AND RELATED WARNINGS:
-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 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:
• 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, 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, centre the saw blade in the kerf and check that saw teeth
are not engaged into the material. If sawblade 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. Supports must be placed under the panel on both sides, near the line of cut and
