Ryobi RY40503 Manuel D'utilisation page 6

 Always maintain a proper stance.
 Do not use chain saw if switch does not turn it
on and off. Have defective switch replaced by
an authorized service center.
 Do not adapt your power head to a bow guide
or use it to power any attachments or devices
not listed for the saw.
 Disconnect chain saw from power supply when
not in use, before servicing, and when making
adjustments and changing attachments, such
as saw chain and guard.
 Do not cut vines and/or small underbrush.
 Do not operate a chain saw in a tree, on a ladder,
rooftop, scaffold, or other unstable support; this
is extremely dangerous.
NOTE: The size of the work area depends on the
job being performed as well as the size tree or
work piece involved. For example, felling a tree
requires a larger work area than making bucking
cuts.
 Do not force the chain saw. The job can be per-
formed better and safer at the rate for which it
was intended.
 Always use the right product for your applica-
tion. The chain saw should be used for cutting
wood only. Never use the chain saw to cut plas-
tic, masonry or non-wood building materials.
 Store chain saw when not in use. Chain saw
should be stored in a dry and high or locked
area out of the reach of children. When storing
chain saw place the scabbard on the bar and
chain and store the chain saw in carrying case.
 Use this product only with batteries and char-
gers listed in tool/appliance/battery pack/char-
ger correlation supplement 988000-842.
 Battery operated units do not have to be
plugged into an electrical outlet; therefore, they
are always in operating condition. Be aware
of possible hazards even when unit is not
operating.
 Remove the battery pack from the chain saw
before cleaning, servicing, storing, removing
material from the unit, changing accessories
such as the bar and chain, or when not in use.
CHAIN SAW SAFETY WARNINGS
KICKBACK
See Figures 1 - 3.
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 reac-
tions 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
chain saw user, you should take several steps
to keep your cutting jobs free from accident or
injury.
 The following precautions should be followed
to minimize kickback:
• Always grip the saw firmly with both hands.
Hold the saw firmly with both hands when
the unit is running. Place your right hand on
the rear handle and your left hand on the
front handle with your thumbs and fingers
encircling the chain saw handles. A firm grip
together with a stiff left arm will help you main-
tain control of the saw if kickback occurs.
• Make sure that the area in which you are cut-
ting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch,
fence, or any other obstruction that could be
hit while you are operating the saw.
• Always cut with the unit running at full speed.
Fully squeeze the throttle trigger and maintain
a steady cutting speed.
• Use replacement parts such as low kick-
back chain, chain brakes and special guide
bars that reduce the risks associated with
rotational kickback. Use only the replacement
guide bars and low kickback chains specified
by the manufacturer for the saw.
