Maintenance and care
7.1.2 Turning the guide rail
In order to avoid one-sided wear on the guide
rail, turn it every time the chain is changed.
7.1.3 Sharpening the saw chain
CAUTION! Risk of injury due to kickback.
Damaged or incorrectly sharpened saw chains in-
crease the danger of kickback! This can result in
injuries.
■
Clean the saw chain regularly.
■
Check the saw chain regularly for damage
and replace if necessary.
■
If you are not familiar with sharpening the
chain: Contact our relevant customer service.
The saw chain must be sharpened in the follow-
ing cases:
■
Only sawdust is thrown out, rather than wood
chips.
■
The polemounted pruner must has to be
forced through the wood during pruning.
For the inexperienced user: Have the saw chain
sharpened by a specialist/customer service. If
you are sharpening the saw chain yourself, heed
the following values. Accessories can be ob-
tained from specialist retailers.

larly intense. Therefore, perform the following
tasks:

2. Clean the drive sprocket and guide rail at-
