The saw chain (2) tension is correct if it can be
raised a maximum of 2 - 3 mm in the centre of the
guide bar (1).
- Tighten the guide bar screws properly after you
have adjusted the saw chain.
Notes
Allow a new saw chain (2) to run for approx. 5
minutes before actually sawing with it. Check the
chain tension again after this time and adjust it if
necessary.
When it is warm, the saw chain (2) will expand
and may sag. This gives rise to the risk tat the saw
chain (2) will jump off the guide bar. Therefore
you must adjust the tension of the chain (2) after
it has carried out its first sawing work.
Since a saw chain (2) that has been tensioned
when warm will contract as it cools and this
would result in excessive chain tension, the chain
tension must be reduced after you have finished
the sawing work.
IMPORTANT – the tension of the chain (2) must be
checked several times over the course of a working day.
Always wear gloves for this work.
Since the guide bar (1) is subject to particularly
high stress at the return point and at the interface,
we recommend that the guide bar be turned
each time you sharpen the chain so as to avoid it
wearing on one side.
Fuel (B12)
Use only a mixture of unleaded regular petrol
and special 2-stroke engine oil in a mixing ratio
of 40:1.
Important: Do not use a different mixing ration
and do not use pure petrol.
Do not use fuel if it is more than 2-3 months old.
If you do not intend to use the machine for a
lengthy period, empty the tank and refill it before
Fit the saw chain
(B5-B9)
- Lay out the chain (2) in a loop. Ensure that the
cutting claws point in a clockwise direction.
- Push the chain (2) over the coupling on to the
sprocket wheel on the chainsaw. Ensure that the
chain links are positioned precisely between the
teeth of the sprocket wheel.
- Now place the chain (2) over the tip of the bar.
Ensure that the chain links are positioned in
the guide bar groove.
The saw chain will sag downwards at this time on
the bottom of the guide bar.
- Now fit the sprocket wheel cover (6) again.
Ensure that the chain adjustment tang engages
in the hole on the guide bar. Only then will
it be possible to fit the sprocket wheel cover (6)
correctly.
Important! The chain must not slip off the guide bar (1) .
the chain links must be positioned precisely between the
teeth of the sprocket wheel.
the chain adjustment tang on the sprocket wheel must
insert the hole on the guide bar.
- Now fit the two guide bar screws (7) again. Only
tighten them by hand at this stage, however.
Tension the saw chain (B10-B11)
Ensure that the guide bar screws (7) for adjusting
the saw chain (2) are only hand tight. Undo them
if necessary.
- To increase the tension of the saw chain (2), turn
the chain adjustment screw (8) clockwise using a
suitable screwdriver.
- To reduce the tension of the saw chain (2), turn
the chain adjustment screw (8) anti-clockwise
using a suitable screwdriver.
