or storing the machine. Such preventive safety
measures reduce the risk of
the machine starting accidentally.
Follow the instructions concerning oiling, tension and
chain accessories rearrangement.
2.6. FORCES OF UNFORESEEN REACTION WHILE
WORKING WITH THE CHAINSAW
2.6.1. BOUNCE
May cause a rebound of the chainsaw if any object
is touched by the chain in the area of the end of the rod
while turned on.
The contact of the chain with the tip of the rod may
cause an unforeseen reaction force that can push
the tip of the rod upwards, generating a
movement in chainsaw rotation that can
cause the chain rod to hit the user. This
reaction can result in loss of control of the machine
and cause severe personal injury.
2.6.2. FORWARD PULL
A "forward pull" can occur when the chain suddenly
stops when it becomes entangled in the cutting in a
foreign body that is in the area of the wood or because
it is not being cut properly. The chain, when stopped,
pushes the chainsaw forward if the chainsaw is not
properly subject against the branch or the tree using
the claw, produces an unexpected hitch which can
cause the user to lose control of the saw, make it fall
forward, and produce severe bodily harm.
To avoid this "forward pull", start the cutting with
full gas power and keep the machine at maximum
revolutions during cutting, while supporting the claw of
the saw against the wood to be cut.
2.6.3. RECOIL
Pinching the chain of the saw on the top of the sword
may push the sword rapidly back toward the operator.
The chain, when stopped, pushes backwards (reverses)
the chainsaw that if the chainsaw is not correctly
clamped against the branch or the tree using the claw,
produces an unexpected push that can cause the
user to lose control of the chainsaw, make you fall
backwards and cause severe personal injury.
Either of these reactions may cause a loss of control
of the saw that is likely to lead to a serious bodily
accident. Do not rely exclusively on the safety devices
built into your saw. As a user of the
chainsaw, you should take measures to eliminate the
risk of accident or injury in his court.
These reaction forces result from misuse of the tool
and/or procedures or incorrect operating conditions
and can be avoided by taking proper precautions
specified below:
• Firmly grasp the chainsaw handles with both
hands.
• Always be aware of where the tip of the chain rod is.
• Ensure that the tip of the rod does not touch
anything.
• Do not cut branches with the tip of the rod.
• Make sure that there are no nails or pieces of
metal in the cutting area and pay special attention
to nails or pieces of iron that may be in or around
the cutting area. Also be careful when cutting
hardwoods where chain can engage causing the
chain to hang and produce the rebound.
• Do not ever cut if you have to raise your arms and
the chainsaw is at shoulder height.
• Begin the cut with full gas power and keep the
machine at maximum revolutions during cutting.
• Cut a single branch or piece of wood at a time.
• Be extremely prudent when the chain of the saw
enters an already-begun cutting area.
