4-1/2" COMPACT CIRCULAR SAW ENG

c) Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.
d) Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a
stable platform. It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
e) Hold power tool by insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will also
make exposed metal parts of the power tool "live"
and shock the operator.
f) When ripping always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbor holes. Blades
that do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade
washers or bolt. The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.
FURTHER SAFETY INSTRUCTIONS FOR ALL SAWS
Causes and operator prevention of kickback:
• Kickbackisasuddenreactiontoapinched,bound
or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward the
operator.
• Whenthebladeispinchedorboundtightlybythe
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the
operator.
• Ifthebladebecomestwistedormisalignedinthe
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 on the saw and position
your arm to resist kickback forces. Position
your body to either side of the blade, but not
in line with the blade. Position the hand not
holding the saw well away from the travel path
of the saw. 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 level 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.
SAFETY INSTRUCTIONS FOR SAWS (CIRCULAR SAW
WITH PIVOTING LOWER GUARD)
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.
