when controlling the power tool� Therefore, proper
holding can reduce the risk of accidents or injuries�
Service
• 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�
• Follow instruction for lubricating and changing ac-
cessories�
safety warnings
Safety instructions for all saws cutting procedures
DANGER: Keep hands away from cutting
area and the blade. Keep your second
hand on auxiliary handle, or motor hous-
ing. If both hands are holding the saw, they
cannot be cut by the blade�
• Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece�
• 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�
• 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 con-
trol� (Circular saw shall be correctly held and processed
workpiece shall be fastened as indicated in figure 14).
• Hold the power tool by insulated gripping sur-
faces only, 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�
• When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding�
• 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�
• 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�

Kickback causes and related warnings
• 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;
• when the blade is pinched or bound tightly by the
kerf closing down, the blade stalls and the motor reac-
tion 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�
Special
Kickback is the result of saw misuse and / or incor-
rect 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 kick-
back 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 kick-
back may occur. Investigate and take corrective
actions to eliminate the cause of blade binding�
• When restarting a saw in the workpiece, cen-
tre 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� (See proper operation in
figure 10.2 and faulty operation in figure 10.1).
• Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kick-
back�
• Blade depth and bevel adjusting locking le-
vers must be tight and secure before making
cut. If blade adjustment shifts while cutting, it may
cause binding and kickback�
• Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback�
Safety instructions for saws with outer pendulum
guard, with inner pendulum guard, with tow guard
• 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 posi-
tion. 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�
• Check the operation of the lower guard spring.
If the guard and the spring are not operating prop-
erly, they must be serviced before use. Lower guard
may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris�
• Lower guard may be retracted manually only
for special cuts such as "plunge cuts" and "com-
pound 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�
• Always observe that the lower guard is cover-
ing 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�
