Kickback Prevention And Operator Safety - GMC LS1200 Manual Del Usuario

• Be aware that the blade will project from the underside of
the workpiece
• Do not reach beneath the workpiece where the guard cannot protect
you from the blade
• Note the direction of rotation of the motor and the blade
• Inspect the workpiece and remove all nails and other embedded
objects prior to starting work
• Do not apply any sideways or twisting force to the blade whilst cutting
• If a cut does not extend to the edge of the workpiece, or if the blade
binds in the cut, allow the blade to come to a complete stop and lift
GB
the saw out of the workpiece
• Do not attempt to free a jammed blade before first disconnecting the
machine from power
• Do not move the saw backwards at any time whilst cutting
• Beware of projected waste. In some situations, waste material
may be projected at speed from the cutting tool. It is the users
responsibility to ensure that other people in the work area are
protected from the possibility of projected waste
• If you are interrupted when operating the saw, complete the process
and switch off before diverting your attention
• The blade bolt and washers were specially designed for your
saw. For optimum performance and safety of operation never use
damaged or incorrect bolt/blade washers
• Regularly check the operation of the blade guard. If the guard does
not automatically cover the blade, have the saw repaired before use
• Periodically check that all nuts, bolts and other fixings have not
loosened, tighten where necessary
The tool must be used only for its prescribed purpose. Any use other
than those mentioned in this Manual will be considered a case of
misuse. The user and not the manufacturer shall be liable for any
damage or injury resulting from such cases of misuse.
The manufacturer shall not be liable for any modifications made to the
tool nor for any damage resulting from such modifications.
Even when the tool is used as prescribed it is not possible to eliminate
all residual risk factors.
KICKBACK PREVENTION AND OPERATOR
SAFETY:
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. Kickback is the result of saw misuse and/or
incorrect operating procedures or conditions and can be avoided by
taking precautions as follows:
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, however, if precautions are taken, kickback
forces can be controlled by the operator.
b. When the blade is binding, or when interrupting a cut for any reason,
release the trigger and hold the saw motionless in the workpiece
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. Investigate and take corrective action to eliminate the cause
of blade binding.
c. When restarting a saw within an incomplete cut, centre the saw
blade in the kerf and check that the saw teeth are not engaged into
the material (a binding saw blade may 'propel upwards' or kickback
from the workpiece as the tool is restarted).
d. A large workpiece should be supported close to the line of the cut,
and at the edge of the panel, to prevent sagging. This will minimise
the risk of blade pinching and kickback.
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 a 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
causing kickback.
h. Check the lower guard before each use and do not use if it does not
close freely, ensuring that the blade does not touch any part of the
guard or tool in all angles and depths of cut. Never clamp or tie the
lower guard in the open position.
i. Check the operation of the lower guard spring. If the guard and the
spring are not operating correctly, they must be serviced before use.
The lower guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
