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.
9.
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.
10.
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.
11.
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 saw
blade is binding, it may walk up or kickback from
the workpiece as the saw is restarted.
12.
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.
To avoid kickback, do support
board or panel near the cut.
000154
Do not support board or
panel away from the cut.

13.
Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
14.
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.
15.
Use extra caution when sawing into existing
walls or other blind areas.
The protruding blade
may cut objects that can cause kickback.
16.
ALWAYS hold the tool firmly with both hands.
NEVER place your hand or fingers behind the
saw.
If kickback occurs, the saw could easily
jump backwards over your hand, leading to
serious personal injury.

17.
Never force the saw. Push the saw forward at
a speed so that the blade cuts without
slowing.
Forcing the saw can cause uneven cuts,
loss of accuracy, and possible kickback.
Lower guard function
18.
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.
19.
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.
20.
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.
