Maintenance
Observe the angles and measurements specified below. If the saw-chain is not
correctly sharpened or the depth gauge is too small, there is a higher risk of kick-
back and injuries resulting from it. The saw-chain cannot be fixed on the chain
guide. It is therefore best to remove the chain from the guide and then to sharpen
it.
•
Select the appropriate tools for the chain pitch sharpening tool. See "Specifica
-
tions" for the allowed chain pitches.
The chain pitch (for example 3/8") is highlighted in the depth of each blade.
Use only special files for chainsaws! Other files have the wrong shape and the
wrong cut.
Select the file according to the diameter of your chain pitch. Make sure to observe
the following angle when sharpening the chain diameter.
A
= filing angle
B = the angle of the side plate
The angle must also be maintained for all knives.
For irregular angles, the chain is run irregularly, wears quickly and breaks down
prematurely.
Since these requirements can only be met with sufficient and regular exercise:
•
A File Holder must be used when sharpening the saw chain by hand. The correct
filing angle marked on it.
•
Hold the file horizontally (at a right angle to the guide rail) and file according to the
angle mark on the file holder. Support the file holder on the top plate and depth
gauge.
•
File down. The knife is always from the inside to the outside
•
The file sharpens only in forward motion. Lift it off in the backward motion.
•
Do not touch the dynamic links with the file.
•
Turn the file regularly continue to avoid a onesided wear.
•
Use a piece of hard wood to remove the burr of the cutting edges.
All knives must have the same length, otherwise they will also vary. As a result, the
chain is irregular and it increases the risk of breaking.
