Replacing the saw chain and guide rail

Replacing the saw chain and guide rail
The saw chain and guide rail are exposed to sig-
nificant wear. Change the saw chain and guide
rail immediately if correct function is not assured.
Note: The replacement chain for the pole-mount-
ed pruner (Art. No.: 112972) can be purchased
separately.

Turning the guide rail

In order to avoid one-sided wear on the guide
rail, turn it every time the chain is changed.

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 pole-mounted pruner must be forced
through the wood during pruning.
For the inexperienced user: Have the saw chain

you are sharpening the saw chain yourself, heed
the following values. Accessories can be ob-

Cleaning the guide rail

built up on the guide rail due to the saw
chain.
3. Turn the guide rail after each chain change/
chain sharpening in order to avoid one-sided
wear.

The load on the drive sprocket (19/2) is particu-
larly intense. Therefore, perform the following
tasks:
1. Check the teeth of the drive sprocket regular-
ly for wear or damage.
2. Clean the drive sprocket and guide rail at-
tachment with a brush.
NOTE A worn or damaged drive sprocket
reduces the service life of the saw chain, and so
the drive sprocket should be renewed without de-
lay by the customer service.
