Causes And Operator Prevention Of Kickback - Ryobi RY40509 Manual Del Operador

 Follow all instructions when clearing jammed
material, storing or servicing the chainsaw.
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the
chainsaw while clearing jammed material or
servicing may result in serious personal injury.
 Carry the chainsaw by the front handle with
the chainsaw switched off and away from
your body. When transporting or storing
the chainsaw always fit the guide bar cover.
Proper handling of the chainsaw will reduce the
likelihood of accidental contact with the moving
saw chain.
 Follow instructions for lubricating, chain
tensioning and changing the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
 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.
CAUSES AND OPERATOR
PREVENTION OF KICKBACK
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and back
towards the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards
the operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw. As a chainsaw
user, you should take several steps to keep your
cutting jobs free from accident or injury.
CHAINSAW SAFETY WARNINGS
Kickback is the result of tool misuse and/or incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
 Maintain a firm grip, with thumbs and fingers
encircling the chainsaw 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 opera-
tor, if proper precautions are taken. Do not let
go of the chainsaw.
 Do not overreach and do not cut above chest
height. This helps prevent unintended tip con-
tact and enables better control of the chainsaw
in unexpected situations.
 Only use replacement bars and chains speci-
fied by the manufacturer. Incorrect replace-
ment bars and chains may cause chain break-
age and/or kickback.
 Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
 Do not start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree. Cluttered areas invite acci-
dents.
 Keep ALL children, bystanders, visitors, and
animals out of the work area while starting or
cutting with the chainsaw. Do not let visitors
contact chainsaw or extension cord.
 Do not operate chainsaw in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Chainsaws create sparks
which may ignite the dust or fumes.
 Dress Properly – Wear snug fitting clothing.
Always wear heavy, long pants, long sleeves,
overalls, jeans or chaps made of cut resistant
material or ones that contain cut resistant
inserts. Wear non-slip safety footwear. Wear
