Servicing and sharpening of saw chain
The correct sharpened chain
Working effectively with the chainsaw is only possible if the chain is in good condition and sharp.
This also reduces the risk of kickback. The chain can be re-sharpened by any dealer. Do not at-
tempt to sharpen the chain yourself unless you have the necessary special tools and experience.
A properly sharpened chain goes way through the wood and it requires very little pressure. Do not
work with a dull or damaged chain. It increases physical exertion, increase the vibrations and leads
to unsatisfactory results and higher wear.
• Clean the chain.
• Check it.
• Replace damaged or worn parts with matching spare parts they are in the shape and size of the
original parts as necessary.
• Sharpening a chain should be performed only by experienced users!
Notice. Below the angle and dimensions If the chain is not properly sharpened or the depth is too
small, there is a higher risk of reversion effects and resulting injuries! The chain cannot be fixed on
the guide rail. It is therefore best to remove the chain from the rail and then sharpen.
• Select the appropriate tools for the chain pitch sharpening tool. See "Specifications" for the al-
lowed chain pitches.
The chain pitch (for example 3/8 ") is highlighted in the depth of each blade.
Use only special files for chain saws! 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 an-
gle 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, wear quickly and break 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.
• Remove to remove a piece of hard wood, bones raw 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 going broke.
