Causes And Operator Prevention Of Kick Back; Safety Warnings For Circular Saws - Skil 5401 Manual De Instrucciones

the power tool's operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
h) Keep handles dry, clean and free from oil and
grease. Slippery handles do not allow for safe handling
and control of the tools 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.
b) In case of consuming of the carbon bru-
shes to send the tool by assistance authorized
technique for substitution. Carbon brushes are
of specify them cause damages to the motor of
the tool.
c) If the power cord or the plug is damaged, the
cord or the plug must be replaced by the manu-
facturer, technical service or by a qualified per-
son to avoid the risk of an electrical shock.

SAFETY WARNINGS FOR CIRCULAR SAWS

a) DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on aux-
iliary handle, or motor housing. If both hands are
holding the saw, they can not 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 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.
e) Hold power tool by insulated gripping sur-
faces 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 shock the operator.
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 wash-
ers or bolt. The blade washers and bolt were spe-
cially designed for your saw, for optimum perfor-
mance and safety of operation.

CAUSES AND OPERATOR PREVENTION OF
KICK BACK:
– Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the work-
piece 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 to-
ward 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 caus-
ing 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 avoid-
ed 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 back-
wards, 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 kick-
back may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
c) 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.
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
