NOTE: Never clean the air filter with petrol or inflammable solvents. In order not
to shorten the service life of the engine, a damaged air filter must be replaced at
once.
WARNING! Never run the engine without the air filter element installed.
Care of the guide rail
Turn the rail around every time you have the chain sharpened or replaced. This will avoid a
one-sided wear of the rail, especially at the top and bottom.
Regularly clean
1 = the opening for the oil supply
2 = the oil passage
3 = the raceway groove of the rail
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. Do not attempt 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!
NOTE: 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 "Technical data" 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
