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 correctly sharpened and clamped saw chain.
Use claw stopper (15) as lever.
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
Never saw with only one hand. Hold the chain
saw always firmly with both hands, left hand on the
front handhold (13) and right hand on the rear
handhold (10).
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.
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.
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.
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. head-
ache, dizziness, nausea, etc.). Otherwise there is an in-
creased risk of accidents.
Make breaks when sawing so that the engine can cool down.
Do not place a hot chain saw in dry grass or onto
inflammable 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).
Saw techniques
Avoid saw backstroke by a correct guiding of the saw.
Note: „Causes and operator prevention of kickback“
Make sure that the wood cannot turn when sawing.
Saw splintered wood with care. There is risk of injury by
wood pieces carried away.
Use the claw stopper (15) 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 of 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 (15) 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.
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 guide bar tip or saw chain.
Adapt shorter trunks before sawing and clamp them firmly.
Avoid cutting of thin bosk and lumber. The chain saw is not
suitable for those works.
Carry out longitudinal cuts with special care as the claw
stopper is not used. Avoid saw backstroke by guiding the
saw with a small angle.
When removing branches from chopped down trees,
leave the larger branches that support the trunk in place. Cut
off the smaller branches as shown.
Branches under tension should be cut from the
bottom to the top to prevent the saw from getting
jammed.
When working at a slope take always the position
above or on the side of the trunk or the lying sawing material
respectively. Pay attention to rolling trunks.
Additional advices for sawing timber under
tension/release
If perches, trees or wood under tension become free of tension
by sawing extreme caution is demanded. The sawing material
can react completely uncontrolled and result in heavy injuries or
death.
Such works shall only be carried out by instructed
specialists.
For all works set always first of all on the pressure
side
the releasing cut and then the dividing cut
-
otherwise the chain saw can jam or strike back.
Upper side of wood under tensile stress
Place one cut (one third of the diameter of the trunk) from
the bottom up.
Then place a second cut on the same point from top which
cuts through the trunk.
