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
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 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 binds, 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 the cut. If blade
adjustment shifts while cutting, it may cause binding
and kickback.
g ) 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 a
Pendulum Blade Guard
a ) Check the 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 the 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 build-up of debris.
c ) The lower guard may be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts". Raise the lower guard by the retracting handle
and as soon as the 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 for
Circular Saws
Wear ear protectors. Exposure to noise can cause
•
hearing loss.
Wear a dust mask. Exposure to dust particles can cause
•
breathing difficulty and possible injury.
Do not use blades of larger or smaller diameter than
•
recommended. For the proper blade rating refer to the
technical data. Use only the blades specified in this manual,
complying with EN847-1.
Use only saw blades that are marked with a speed equal
•
or higher than the speed marked on the tool.
Avoid overheating of blade tips.
•
Install the dust extraction port onto the saw before use.
•
Never use abrasive cut-off wheels.
•
Do not use water feed attachments.
•
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.
Residual Risks
In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
•
Impairment of hearing.
