Prior to changing the saw chain, the groove of the guide bar must be cleaned of dirt
because dirt deposits can cause the saw chain to break out of the groove. The deposits
can also absorb the chain oil. So the consequence would be that the chain oil would not or
only a small part of it would reach the underside of the groove and the lubrication would
be reduced.
Never attach a new chain to a worn sprocket or place onto a damaged or worn guide bar.
The chain could spring back or break, potentially leading to serious injury.
Adjusting the tension of the saw chain
Regular tightening the saw chain provides safety for the user and reduces and/or prevents
wear and chain damages. Before the start of work and in approx. 10 minute intervals, 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. Therefore, you have to re-tension the chain after
the first 5 cuts and no later than after 10 minutes' sawing time.
Do not re-tighten or change the chain when it is hot because it shrinks slightly once it
has cooled down. In case of nonobservance, this can lead to damages on the groove
or the engine because now the chain is too taut on the guide bar. Chain tension and
chain lubrication have a significant impact on the service life of the saw chain.
The chain is correctly tensioned if:
• it does not sag at the groove underside
• can be rotated completely around with the gloved hand
• the gap between the saw chain and the guide bar groove is not more than 2 mm.
Switch off the power tool and remove the battery before carrying out any
maintenance work.
1. Loosen the mounting knob of the sprocket cover.
2. To tension the saw chain, turn the chain tension adjustment screw clockwise. To loosen
the tension, turn the screw anticlockwise.
3. Tighten the mounting knob of the sprocket cover again.
The chain tension of a new saw chain must be readjusted after a maximum of 5 cuts.
