9. 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 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:
a. 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.
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 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. Supports 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 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 making a
″plunge cut″ into existing walls or other
blind areas. The protruding blade may
cut objects that can cause kickback.
10. 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.
11. 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.
12. 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.
13. 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 Trigger is released.
14. DO NOT USE THIS SAW WITH THE
SAW HELD UpSIDE DOWN IN A VISE.
The saw is not designed for such use and
cannot be used safely in that position.
15. Do not use to cut logs, tree
limbs, or uneven lumber.
16. Wet lumber, green (unseasoned) lumber,
and pressure treated lumber all have an
increased potential for kickback and should
only be cut with a blade for cutting that
lumber type. Wear a NIOSH-approved
respirator and have appropriate ventilation
whenever cutting pressure treated lumber.
17. Do not use blades made from high-speed
steel, abrasive blades, metal-cutting
blades or masonry-cutting blades. The
guards of this saw are not designed to
protect against the failure of such blades.
18. place the larger portion of the saw base on
the larger, supported part of the workpiece.
This will help maintain balance and
control while the cut is completed.
