• When using a torque wrench, the tightening torque
is 12-15 Nm.
• Plug the spark plug socket correctly on the plug.
Clean the air filter Fig. 32-35
Soiled air filters reduce the engine power by sup-
plying too little air to the carburetor. Dust and pollen
plug up the pores of the filter made of foamed plastic.
Regular checks are therefore essential.
• Unclip the air filter cover and remove the sponge
filter element.
• To avoid objects falling into the air tank, replace
the air filter cover.
• Wash the filter element in warm soap water, rinse
and allow drying naturally.
Important: 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.
m Warning!
Never run the engine without the air filter ele-
ment 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 possi-
ble 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 attempt to sharp-
en 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 dam-
aged 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 angle when
sharpening the chain diameter.
A = filing angle
B = the angle of the side plate
2
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 suf-
ficient and regular exercise:
1
• A File Holder must be used when sharpening the
3
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.
