Chain Saw Safety Warnings; Causes And Operator Prevention Of Kickback - Stiga SEV 2416 Q Manual De Instrucciones

SAFETY WARNINGS
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.
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.

CHAIN SAW SAFETY WARNINGS:

• Keep all parts of the body away from the saw chain
when the chain saw is operating. Before you start the
chain saw, make sure the saw chain is not contacting
anything. A moment of inattention while operating chain saws
may cause entanglement of your clothing or body with the
saw chain.
• Always hold the chain saw with your right hand on
the rear handle and your left hand on the front handle.
Holding the chain saw with a reversed hand configuration
increases the risk of personal injury and should never be done.
• Wear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet is
recommended. Adequate protective clothing will reduce
personal injury by flying debris or accidental contact with the
saw chain.
• Do not operate a chain saw in a tree. Operation of a chain
saw while up in a tree may result in personal injury.
• Always keep proper footing and operate the chain saw
only when standing on fixed, secure and level surface.
Slippery or unstable surfaces such as ladders may cause a
loss of balance or control of the chain saw.
• When cutting a limb that is under tension be alert for
spring back. When the tension in the wood fibres is released
the spring loaded limb may strike the operator and/or throw
the chain saw out of control.
• Use extreme caution when cutting brush and saplings.
The slender material may catch the saw chain and be whipped
toward you or pull you off balance.
• Carry the chain saw by the front handle with the chain
saw switched off and away from your body. When trans-
porting or storing the chain saw always fit the guide
bar cover. Proper handling of the chain saw will reduce the
likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning and
changing accessories. Improperly tensioned or lubricated
chain may either break or increase the chance for kickback.
• 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 chain saw for purposes not
intended. For example: do not use chain saw for cutting
plastic, masonry or non-wood building materials. Use
of the chain saw 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 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 loose 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 chain saw 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 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 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.
• 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 bars and chains specified by the
manufacturer. Incorrect replacement bars and chains may
cause chain breakage 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.
• Techniques for using the electric chain-saw
Always observe the safety regulations and use the most suit-
able sawing techniques (see chapter 7 for instructions and
examples).
Arrange the power cable so that it does not get tangled in
branches or other obstacles.
• Safe carrying of the saw
Whenever the machine is to be handled or transported you
must:
– turn off the engine, wait for the chain to stop and unplug the
machine from the mains;
– mount the bar cover;
– only hold the machine using the handgrips and position the
bar in the opposite direction to that used during operation.
When using a vehicle to transport the machine, position it so that
it can cause no danger to persons and fasten it firmly.
• Recommendation for the first-time users
Before felling or delimbing for the first time, make sure:
– you have been specifically trained to use this type of equip-
ment;
– you have carefully read the safety regulations and user in-
structions contained in this manual;
– you practise first on logs on the ground or attached to trestles,
in order to get familiar with the machine and the most suitable
cutting techniques.
