e. Do not use dull or damaged blades. 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 sawing into existing walls or other blind areas.
The protruding blade may cut objects that can cause
kickback.
The protruding blade may cut objects that can cause kickback.
a. 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, in all angles
and depths of cut.
b. 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.
c. Lower guard should 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.
d. Always observe that the lower guard is covering the blade before placing
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.
e. Do not use abrasive wheels.
Wear eye protection
Wear ear protection
Wear breathing protection
d. Support large panels to minimise 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.
a.
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.
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, centre the saw blade in the
kerf so that the saw teeth are not engaged into the material.
If a saw blade is binds, it may walk up or kickback from the workpiece as
the saw is restarted.
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 misal
igned 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.
