Causes And Operator Prevention Of Kickback - Snapper SC60V Manual De Instrucciones

slippery causing loss of control.
• Cut wood only. Do not use chainsaw for
purposes not intended. For example:
do not use chainsaw for cutting plastic,
masonry or non-wood building materials.
Use of the chainsaw for operations different
than intended could result in a hazardous
situation.
WARNING:
power sanding, sawing, grinding, drilling,
and other construction activities contain
chemicals known to cause cancer, birth
defects or other reproductive harm. Some
examples of these chemicals are:
1. Lead from lead-based paints.
2. Crystalline silica from bricks and cement
and other masonry products, and
3. Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals, work in a well-ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.
KICKBACKS
WARNING:
Kickback may occur when
the moving chain contacts an object at the
upper portion of the tip of the guide bar or
when the wood closes in and pinches the saw
chain in the cut. Contact at the upper portion
of the tip of the guide bar can cause the chain
to dig into the object and stop the chain for an
instant. The result is a lightning fast reverse
reaction which kicks the guide bar up and
back toward the operator. If the saw chain is
pinched along the top of the guide bar, the
guide bar can be driven rapidly back toward
the operator. Either of these reactions can
cause loss of saw control which can result in
serious injury. Do not rely exclusively upon
the safety devices built into the saw. As
a chainsaw user, you should take several
steps to keep your cutting jobs free from
accident or injury.
CAUSES AND OPERATOR PREVENTION
OF KICKBACK
1. Maintain a firm grip, with thumbs and
fingers encircling the chain saw handles,
with both hands on the saw and position
your body and arm to allow you to resist
kickback forces. Kickback forces can be
controlled by the operator, if proper precautions
are taken. Do not let go of the chain saw.
SAFETY RULES
Some dust created by
2. Do not overreach and do not cut above
shoulder height. This helps prevent
unintended tip contact and enables better
control of the chain saw in unexpected
situations.
3. Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause chain
breakage and/or kickback.
4. Follow the manufacturer's sharpening
and maintenance instructions for the saw
chain. Decreasing the depth gauge height
can lead to increased kickback.
