into the clamp. The plug connection is now saved
against automatic release.
When carrying out the works observe that the extension
cable is always leading backwards from the chain saw,
and is outside the zone of the saw chain and the sawing
material.
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 sword pike gets in contact with the sawing material
(unintended) or other hard objects.
−
in case of jamming saw chain.
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 (16) is not put on.
How to avoid saw backstroke?
−
Never try to put on the sword pike for cutting.
12
−
Never saw with the upper egde of the sword pike.
13
−
Always put on the chain saw as plane as possible.
15
−
Start cutting only with running saw chain.
−
Never switch on the machine with the saw chain put on.
−
Only work with sharp and correctly sharpened saw
chain.
−
Never work with loose or worn out saw chain.
−
Only work with correctly clamped saw chain.
−
Always hold the chain saw firmly with both hands.
−
Use claw stopper as lever.
16
−
Never work above height of shoulders.
−
Never cut through several perches at the same time.
When releasing make sure that no other perch is
touched.
−
If possible use a sawhorse when cutting to length.
−
Stab cuts shall only be carried out by instructed
personal.
General conduct when sawing
+
Do not work on snow, ice or recently peeled wood – slip
hazard.
+
Do not work under insufficient light conditions (e.g. fog,
rain, snow flurry or twilight). You can not see anymore
details within the falling area – risk of accident.
+
Provide for a safe and cleaned workplace.
+
Avoid abnormal posture. Keep at any time the balance.
Do not work with the upper part of the body leaned
forward.
+
Operate the chain saw only with safe standing position.
Hold the chain saw slightly on the right of the own body.
+
Do not use the chain saw for lifting or moving of wood.
+
Make sure that the wood is free of foreign object
(stones, nails etc).
+
Hold the chain saw always firmly with both hands, left
hand on the front handhold (4) and right hand on the
rear handhold (17). Never saw with only one hand.
14
+
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.
+
Initiate saw chain before getting in contact with the
wood.
+
Only cut the sawing material with the lower edge.
Cutting with the upper edge causes saw backstrokes.
+
Put on the chain saw as plane as possible.
+
Use the claw stopper (16) for fixing the chain saw on
the wood. Use the claw stopper when sawing as lever.
16
+
When sawing thicker perches or trunks set back the
claw stopper (16) 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.
+
Let the chain saw work by producing a light leverage
pressure over the claw stopper. When sawing do not
press with strength.
+
Never work
−
with stretched arms
−
on hardly accessible places
−
standing on a ladder, a staging or a tree.
+
Never saw with the chain saw above shoulder height.
+
Do not overload the chain saw. You obtain best cutting
results when the chain speed does not fall.
+
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.
+
Never get in contact with the running saw with metallic
fences or the ground.
+
Switch off the chain saw between the cuts when several
cuts are carried out.
+
If the saw chain jams in the wood switch off immediately
the device and pull out the power plug. Use a block to
free the sword.
+
Make breaks when sawing so that the electric motor
can cool down.
Additional advices for sawing
trunks
+
Never put the trunk for sawing on the ground. Support
the trunk in such manner that the cut does not close
and the saw chain jams. Use a safe base (e.g.
sawhorse). Avoid contact to ground with the sword pike
or saw chain.
+
Adapt shorter trunks before sawing and clamp them
firmly.
