Causes And Operator Prevention Of Kickback - Ryobi P25013 Manuel D'utilisation

„ Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
„ Cut wood only. Do not use pruner for purposes not
intended. For example: do not use pruner for cutting
plastic, masonry or non-wood building materials. Use
of the pruner for operations different than intended could
result in a hazardous situation.
„ Maintain a firm grip, with thumbs and fingers en-
circling the pruner handles, with both hands on the
pruner. Maintaining control of the pruner will reduce the
risk of losing control. Do not let go of the pruner.
„ Do not overreach and do not cut above chest height.
This helps prevent unintended tip contact and enables
better control of the pruner in unexpected situations.
„ Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and chains
can cause chain breakage and increase the risk of injury.
„ Follow the manufacturer's sharpening and mainte-
nance instructions for the pruner chain. Decreasing the
depth gauge height can lead to increased risk of injury.
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 reac-
tion, 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 pruner user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect operat-
ing procedures or conditions and can be avoided by taking
proper precautions as given below:
„ 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 kick-
back forces. Kickback forces can be controlled by the
operator, if proper precautions are taken. Do not let go
of the chain saw.
„ 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.
„ Only use replacement guide bars and saw chains speci-
fied by the manufacturer. Incorrect replacement guide
bars and saw chains may cause chain breakage and/or
kickback.
PRUNING SAW SAFETY WARNINGS
„ 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, se-
cure footing, and a planned retreat path from the falling
tree. Cluttered areas invite accidents.
„ Keep ALL children, bystanders, visitors, and animals out of
the work area while starting or cutting with the pruning saw.
Do not let visitors contact pruning saw or extension cord.
„ Do not operate pruning saw in explosive atmospheres,
such as in the presence of flammable liquids, gases, or
dust. Pruning saws 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
non-slip heavy duty gloves to improve your grip and to
protect your hands. Do not wear jewelry, short pants,
sandals, or go barefoot. Do not wear loose fitting clothing,
which could be drawn into the motor or catch the chain
or underbrush. Secure hair so it is above shoulder level.
Wear hearing and head protection.
„ Heavy protective clothing may increase operator fatigue,
which could lead to heat stroke. During weather that is
hot and humid, heavy work should be scheduled for early
morning or late afternoon hours when temperatures are
cooler.
„ Always wear eye protection with side shields marked
to comply with ANSI Z87.1 as well as hearing and head
protection when operating this equipment.
„ Always be aware of what you are doing when using the
pruning saw. Use common sense. Do not operate the
pruning saw when you are tired, ill, upset, or under the
influence of alcohol, drugs, or medication.
„ Do not expose the pruning saw to rain.
„ Do not use the pruning saw in damp or wet locations.
„ Stay alert and pay attention to what you are doing. Use
common sense when using this unit.
„ Keep all parts of your body away from the saw chain
when the unit is running.
„ Never let anyone use your pruning saw who has not
received adequate instructions in its proper use. This
applies to rentals as well as privately owned saws.
„ Before you start the unit, make sure the saw chain is not
contacting any object.
„ Stop the pruning saw before setting it down.
„ To avoid accidental starting, never carry the unit with your
