performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
5) Service
a ) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
ADDITIONAL SPECIFIC SAFETY RULES FOR
CIRCULAR SAW
Safety Instructions for All Saws

DANGER:
a ) Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or motor
housing. If both hands are holding the saw, they cannot
be cut by the blade.
b ) Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
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 the workpiece in your hands or across
your leg while cutting. 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 the 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 could give the operator
an electric shock.
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 arbour 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:
• 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;
36
• 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, 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.
d ) 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.
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.
Safety Instructions for Saws with a
Pendulum Blade Guard
a ) Check the lower guard for proper closing before each
use. Do not operate the saw if the lower guard does
not move freely and close instantly. Never clamp
or tie the lower guard into the open position. If the
saw is accidentally dropped, lower the 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.
