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 saw
blade is binding, it may walk up or kickback from
the workpiece as the saw is restarted.
• 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 minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the
saw on the workpiece, the saw should be rested on
the larger portion and the smaller piece cut off.
(Fig. B & C)
To avoid kickback, do support board or panel
near the cut.
Do not support board or panel away from the cut.
• Do not
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback. Keep blade sharp and clean.
Gum and wood pitch hardened on blades slows
saw and increases potential for kickback. Keep
blade clean by first removing it from tool, then
cleaning it with gum and pitch remover, hot water
or kerosene. Never use gasoline.
• 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.
• 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. For plunge cuts, retract lower guard
using retracting handle.
• 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. (Fig. D)
• Never force the saw. Forcing the saw can
cause uneven cuts, loss of accuracy, and
possible kickback. Push the saw forward at a
speed so that the blade cuts without slowing.
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
Fig. B
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.
To check lower guard, open lower guard by hand,
then release and watch guard closure. Also check to
see that retracting handle does not touch tool
housing.
DANGEROUS and can lead to serious personal
injury.
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
