Switching On / Off; Working With The Power Pruner; Saw Backstroke; How To Avoid Backstrokes - ATIKA KSH 710 SDS Notice Originale

Thread the extension cable through the pull relief device

(14) as a loop and hang it up.
Make sure that the extension cable has sufficient play

and is routed toward the rear away from the power
pruner, outside of the range of the saw chain and
material to be sawed.

Switching on / off

Do not use any device where the switch can not be
switched on and off. Damaged switches must be repaired
or replaced immediately by the customer service.
Securely support the power pruner when switching it on and
hold it with both hands. Chain and guide bar must stand free.
Switching on

Working with the power pruner

Saw backstroke

What is saw backstroke? Saw backstroke is the sudden strike
upwards or backwards of the running power pruner 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 power pruner reacts uncontrolled and frequently causes
heavy injuries of the operator.
How to avoid saw backstroke?
− For better control saw with the lower edge of the guide bar.
Place the power pruner as horizontally as possible 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.
− Never switch on the machine with the saw chain put on.
− Always hold the power pruner firmly with both hands.
− Only work with correctly sharpened and clamped saw chain.

General conduct when pruning

 Take into consideration environmental influences:
− Do not work on snow, ice or recently peeled wood
hazard.
− Do not work under insufficient light conditions (e.g. fog,
rain, snow flurry or twilight). You cannot see any more
details within the falling area
slip
–
risk of accident.
–
− Delay the work in case of disadvantageous weather
(rain, snow, ice, wind)
− Do not use the power pruner near inflammable liquids or
gases.
− Keep a safety distance of 10 m to overhead power lines.
− Do not use the power pruner in a humid or wet
environment.
Plan an escape route from falling branches in advance. This

escape route must be free from obstacles to ensure
retreating without danger.
 Position yourself outside the range of falling branches.
 Make sure that someone is within calling distance in case of
an accident.
 Keep other persons away. The safety distance is 2.5-times
the length of the branch to be cut, but at least 6 m. 
 Avoid abnormal posture. Keep at any time the balance. Do
not work with the upper part of the body leaned forward.
Operate the power pruner only with safe standing position.

Hold the power pruner slightly to the right of the own body.
Hold the power pruner always firmly with both hands, left

hand on the front handle (19) and right hand on the rear
handle (16). Always use the carrying strep supplied.
 Frequently change the working position to prevent a one-
sided work position.
Immediately stop working when you feel unwell (e.g.

headache, dizziness, nausea, etc.). Otherwise there is an
increased risk of accidents. Observe sufficient break times
to rest.
 Never work
− with stretched arms
− standing on a ladder, a staging or a tree.
 Do not attempt to hit an already existing cut.
 Do not use the power pruner for lifting or moving of wood.
 Saw splintered wood with care. There is risk of injury by
wood pieces carried away.
 Make sure that the wood is free of foreign object (nails etc).
 Do not overload the machine! You work better and safer in
the given performance range.
 Be careful at the end of a sawing cut. As soon as the power
pruner leaves the wood the force of weight changes. There
is risk of accident for legs and feet.
 Remove the power pruner only with running saw chain out
of the cut.
 If the saw chain gets jammed in the wood, stop it
immediately and remove the mains plug from the socket.
Use a wedge to free the guide bar.
 Do not use any cracked saw chains or such that have
changed their shape.
 Never touch wire fences or the ground with the running saw
chain.
 Switch off the power pruner between the cuts when several
cuts are carried out.
 Make breaks when sawing so that the engine can cool
down.

Before sawing

Carry out the following checks before the initiation and regularly
during the sawing process:
 Has the power pruner been assembled completely and
properly?
increased risk of accidents!
