Altrad Oregon TRON-2400L-40 Notice Originale page 21

Use only original spare. Accidents can arise for the user
through the use of other spare parts. The manufacturer is
not liable for any damage or injury resulting from such
action.
Safety instructions - operation
Never saw with only one hand. Hold the
chain saw always firmly with both hands, left hand
on the front handhold (4) and right hand on the
rear handhold (17).
Hold the chain saw slightly on the right of the own body.
Avoid abnormal posture. Provide a safe standing position
and keep at any time the balance.
Never work
− with stretched arms
− on hardly accessible places
− above shoulder height
− standing on a ladder, a staging or a tree.
Activate the chain brake when moving to a tree.
Before leaving the chain saw (work break) bring it in a safe
condition (cover the guide bar, apply the chain brake) and
put it on a place where nobody is endangered. Secure the
chain saw against unauthorized access.
Safety instructions - while sawing
Never work alone. Keep acoustic and visual contact to
other persons at all times to allow immediate first aid in
emergency cases.
Immediately stop the engine at imminent danger or in
emergency cases.
Never leave the saw running unattended.
Immediately stop working when you feel unwell (e.g.
headache, dizziness, nausea, etc.). Otherwise there is an
increased risk of accidents.
When switching on the chain saw must be supported and
held safely. Chain and guide bar must stand free.
Start cutting only when the saw chain has reached the full
number of revolutions.
Do not overload the machine! You work better and safer in
the given performance range.
Do not use the chain saw for lifting or moving of wood.
Make breaks when sawing so that the engine can cool
down.
Do not place a hot chain saw in dry grass or onto inflam-
mable objects.
Never get in contact with the running saw with metallic
fences or the ground.
Make sure that the wood is free of foreign object (stones,
nails etc).
Make sure that the wood can not turn when sawing.
Saw splintered wood with care. There is risk of injury by
wood pieces carried away.
Avoid saw backstroke by a correct guiding of the saw.
Note: Safety instructions - saw backstroke
Use the claw stopper (16) for fixing the chain saw on
the wood. Use the claw stopper when sawing as lever.
Do not use the chain saw for lifting or moving wood.
Let the chain saw work by producing a light leverage
pressure over the claw stopper. When sawing do not press
with strength.
When sawing thicker perches or trunks set back the claw
stopper on a deeper point. For setting back release the claw
stopper from the wood and place it again in a deeper
position. Do not remove the saw here out of the cut.
Be careful at the end of a sawing cut. As far as the saw
leaves the wood the force of weight changes. There is risk
of accident for legs and feet.
Remove the chain saw only with running saw chain out of
the cut.
If the saw chain gets jammed in the wood, stop it
immediately. Use a wedge to free the guide bar.
Vibrations
If persons who have blood circulation problems are too
often exposed to vibrations damages to the nervous system or
to blood vessels may occur.
You can reduce vibrations
- by thick and warm working gloves,
- shorter working time (have longer breaks).
See a doctor if your fingers swell, you don't feel well or your
fingers become numb.
Safety instructions - saw backstroke
What is saw backstroke? Saw backstroke is the
sudden strike upwards or backwards of the
running chain saw in direction of the operator.
This happens when
−
the guide bar tip gets in contact with the sawing
material (unintended) or other hard objects.
− the saw chain is jammed at the guide bar tip.
The chain saw reacts uncontrolled and causes frequently heavy
injuries with the operator.
Carry out lateral cuts, diagonal cuts and longitudinal cuts
with increased attention because here the claw stopper is not
put on.
How to avoid saw backstroke?
Always hold the chain saw firmly with both hands.
For better control saw with the lower edge of the
guide bar. Hold the chain saw as close as possible to the
horizontal position when contacting wood.
Never saw with the guide bar tip.
Sawing with the upper guide bar edge may cause a
saw backstroke if the saw gets jammed or hits a hard object
in the wood.
Start cutting only with running saw chain.
Only work with sharp and correctly sharpened saw chain.
Only work with correctly clamped saw chain.
Use claw stopper (16) as lever.
