Crown CT15134-165 [23/180] Safety guidelines during power tool operation

English
• Follow instruction for lubricating and changing ac-
cessories�
Special 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
housing. 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 control� (Circular
saw shall be correctly held and processed workpiece
shall be fastened as indicated in gure 16).
• Hold the power tool by insulated gripping
surfaces 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 re-
action drives the unit rapidly back toward the opera-
tor;
• 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 incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below�
• Maintain a rm 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 at-
tempt 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�
• 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
gure 13.2 and faulty operation in gure 13.1).
• 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
levers 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 plunge type saw
• Check guard for proper closing before each use.
Do not operate the saw if guard does not move
freely and enclose the blade instantly. Never clamp
or tie the guard so that the blade is exposed. If saw
is accidentally dropped, guard may be bent� Check to
make sure that guard moves freely and does not touch
the blade or any other part, in all angles and depths of
cut�
• Check the operation and condition of the guard
return spring. If the guard and the spring are not
operating properly, they must be serviced before
use. Guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris�
• Assure that the base plate of the saw will not
shift while performing the "plunge cut" when the
blade bevel setting is not at 90°. Blade shifting
sideways will cause binding and likely kick back�
• Always observe that the guard is covering the
blade before placing saw down on bench or oor.
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 all saws with
riving knife
• Use the appropriate saw blade for the riving
knife. For the riving knife to function, the body of
the blade must be thinner than the riving knife and
the cutting width of the blade must be wider than the
thickness of the riving knife�
• Adjust the riving knife as described in this
instruction manual. Incorrect spacing, positioning
