to break out of the rail. The deposits can
also absorb the chain oil. So the conse-
quence would be that the chain oil would
not or only a small part of it would reach
the underside of the rail and the lubrication
would be reduced.
Tensioning the saw chain
Regularly tightening the saw chain provides
safety for the user and reduces and/or pre-
vents wear and chain damages. Before the
start of work and in approx. 10 minute inter-
vals, we recommend the user to examine the
chain tension and correct it, if necessary.
The chain warms up when working with
the saw and thus expands slightly. These
"expansions" can be expected especially
from newer chains.
Do not re-tighten or change the
chain when it is hot because it
shrinks slightly once it has cooled
down. In case of non-observance,
this can lead to damages on the
guide rail or the engine because
now the chain is too taut on the
blade. Chain tension and chain lu-
brication have a signifi cant impact
on the service life of the chain.
The chain is correctly tensioned if it does
not sag at the rail underside and can be
rotated completely around with the gloved
hand. When the saw chain is tensioned
with 9 N (approx. 1 kg), the gap between
the saw chain and the guide rail may not
be more than 2 mm.

1. Ensure that the chain brake has been
released, that is, that the chain brake
lever (3) is pulled up against the front
grip (16).
2. Loosen the nut (7) with the combination
wrench (12) by turning it in a counter-
clockwise direction (

With a new saw chain, you must
readjust the chain tension after at
least 5 cutting operations.

Chain lubrication
The rail and chain must never be
without oil. If you operate the elec-
tric chainsaw with too little oil, the
cutting performance and the lifetime
of the saw chain is reduced, since
the chain becomes blunt faster. You
can identify a case of too little oil
where smoke development or dis-
coloration of the rail occurs.
As soon as the motor is speeded up, the oil
also fl ows faster to the chain bar (4).
Filling up with chain oil:
• Check the oil level indicator (25) regu-
larly and top-up the oil if the minimum
mark „MIN" (26) is reached on the oil
level indicator. The oil tank volume can
be found in the "Technical data" section.
• Use bio-oil containing additives to redu-
ce friction and wear. You can order this
from our online shop.
