the risk of personal injury and should never be
done.
c)
Hold the chaisaw by insulated gripping
surfaces only, because the chainsaw
may contact hidden wiring. Saw chains
contacting a "live" wire may make exposed
metal parts of the chain saw "live" and could
give the operator an electric shock
d) Wear eye protection. Further protective
equipment for hearing, head, hands,
legs and feet is recommended. Adequate
protective equipment will reduce personal
injury from flying debris or accidental contact
with the saw chain.
e) Do not operate a chain saw in a tree, on
a ladder, from a rooftop, or any unstable
support. Operation of a chain saw in this
manner could result in serious personal injury.
f) Always keep proper footing and operate
the chain saw only when standing on
fixed, secure and level surface. Slippery
or unstable surfaces may cause a loss of
balance or control of the chain saw..
g) When cutting a limb that is under tension,
be alert for spring back. When the tension
of the wood fibres is released, the spring
loaded limb may strike the operator and/or
throw the chain saw out of control..
h) Use extreme caution when cutting brush
and saplings. The slender material may
catch the saw chain and be whipped toward
you and/or pull you off balance.
i) Carry the chainsaw by the front handle with
the chain saw switched off and away from
your body. When storing or transporting a
chainsaw always use the guide bar cover.
Proper handling of the chain saw will reduce
the likelihood of accidental contact with the
moving saw chain.
j) Follow the 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.
k) Cut wood only. Do not use the chainsaw
for purposes not intended. For example:
do not use an chainsaw for cutting
metal, plastic, masonry or non-wood
building materials. Use of the pruner saw for
operations different than intended could result
in a hazardous situation.
l) Do not attempt to fell a tree until you have
an understanding of the risks and how to
avoid them. Serious injury could occur to the
operator or bystanders while felling a tree.
m) This chain saw is not intended for tree
felling. Use of the pruner saw for operations
different than intended could result in serious
injury to the operator or bystanders
n) Follow all instructions when clearing
jammed material, storing or servicing the
chain saw. Make sure the switch is off,
the lock-off is in the locked position and
the battery pack is removed. Unexpected
actuation of the chain saw while clearing
jammed material or servicing may result in
serious personal injury.
o)
To reduce the risk of electrocution, never
use the extended-reach hedge trimmer
near any electrical power lines. Contact
with or use near power lines may cause
serious injury or electric shock resulting in
death.
•
Prolonged exposure to vibrations can
cause injuries and neurovascular disorders
(also called "Raynaud's syndrome" or "white
finger"), especially to people suffering from
circulation disorders. The symptoms can appear
in the hands, wrists and fingers and are shown
through loss of sensitivity, torpor, itching, pain
and discolouring of or structural changes to
the skin. These effects can be worsened by low
ambient temperatures and/or by gripping the
hand grips excessively tightly. If the symptoms
occur, the length of time the machine is used
must be reduced and a doctor consulted.
• It is recommended that those operating
chainsaws for trimming and performing height
work aided by a rope and belt harness:
– should never work alone;
– should be assisted by an operator on
the ground who has received training on
appropriate emergency procedures;
– should have received training on secure
climbing and work positions for this type of
job;
– are supplied with belt harnesses, ropes, flat
belts with end loops, clasp clips and other
recommended additional safety equipment or
any other system that prevents the operator
and chainsaw from falling.
• Perform cleaning and maintenance before
storing the machine after use.
• Improper maintenance, use of non-compliant
spare parts or modification of the safety devices
can cause damage to the device and cause
serious injury to the user.
2.3 CAUSES OF KICKBACK AND
OPERATOR PROTECTION
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.
