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.
Lower guard safety instructions
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 buildup 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 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 switch is released.
ADDITIONAL SAfeTy INSTRUCTIONS
•
Use clamps or another practical way to
secure and support the workpiece to a
stable platform.
Holding the work by hand
or against your body leaves it unstable and
may lead to loss of control.
•
keep your body positioned to either
side of the blade, but not in line with the
saw blade.
KICKBACK could cause the
saw to jump backwards (see
Causes and
Operator Prevention of kickback and
kICkBACk)
.
•
Avoid cutting nails. Inspect for and
remove all nails from lumber before
cutting.
•
Always make sure nothing
interferes with the movement of the
lower blade guard.
•
Accessories must be rated for at
least the speed recommended on the
tool warning label.
Wheels and other
accessories running over rated speed
can fly apart and cause injury. Accessory
ratings must always be above tool speed
as shown on tool nameplate.
•
Always make sure the saw is clean
before using.
•
Stop using this saw and have it properly
serviced if any unusual noise or abnormal
operation occurs.
•
Always be sure all components are
mounted properly and securely before
using tool.
•
Always handle the saw blade with care
when mounting or removing it or when
removing the diamond knockout.
•
Always wait until the motor has reached
