Before each maintenance and cleaning work
−
switch off device
−
wait for stop of chain saw
−
pull out main plug
Further maintenance and cleaning works than described in this
chapter shall only be carried out by the manufacturer or
companies named by the manufacturer.
For maintaining and cleaning, removed security devices must
unconditionally be mounted properly and proved again.
Use only original parts. Other parts can result in unexpected
damages and injuries.
Maintenance
In order to avoid possible injuries wear gloves.
To guarantee a long and reliable usage of the chain saws carry
out the following maintenance works regularly.
Check the chain saw for obvious defects such as
−
loose, hung out or damaged saw chain
−
loose fastenings
−
worn or damaged components
Check the chain saw after each application for
−
wear, especially chain, guide bar and chain wheel.
−
correctly assembled and faultless covers and protective
devices.
Necessary repair works or maintenance works have to be
carried out before the usage of the chain saw.
Sharpening of saw chain
You can only work safely and well with a sharp
and clean saw chain. Damaged or incorrectly
sharpened saw chains increase the risk of
kickbacks.
The saw chain has to be sharpened if
½
only wood dust is thrown out instead of shavings
½
you have to press the chain saw through the wood during
cutting
L
Inexperienced users: Have the saw chain sharpened by a
specialist/service workshop.
You can also sharpen your saw chain yourself by using our
electric sharpener KSG 220 (article-no.: 302360).

Exchanging saw chain and guide bar
Saw chain and guide bar are exposed to great wearing
demands. Immediately exchange saw chain and guide bar
when the faultless function is not guaranteed.
B
Put the chain saw on an even face.
B
Remove the cover (10) by loosening the fastening screw
(11).
B
Turn the chain clamper (22) anti-clockwise in order to
release the saw chain a bit.
B
Take off the guide bar with saw chain.
B
Clean the guide slot thoroughly when only the saw chain is
exchanged.
B
When assembling, pay attention that the chain links are
lying correctly within the guide slot and on the chain wheel
(13).
B
Turn the chain clamp (22) clockwise until the saw chain is
clamped.
B
Now, refasten the cover (10).
B
Clamp the saw chain as described in paragraph „Clamping
of saw chain“.
Chain wheel
The demand of the chain wheel (13) is particularly great. Check
regularly the teeth of the chain wheel for wear or damages.
L
A worn or damaged chain wheel reduces the
durability of the saw chain and should therefore
immediately be exchanged by the customer service.
Checking of the oil automatic
Check the function of the automatic chain lubrication by
switching on the chain saw and holding it with the pike in
direction of a carton or paper on the ground.
Do not get in contact with the ground with the chain. Keep a
safe distance of 20 cm.
If an increasing oil track is caused when checking it the oil
automatic works faultless.
If there is no oil track despite full oil tank
B
clean the oil flow canal (14) and the upper chain
clamping boring (15).
B
If this is not successful please contact the customer service.
Cleaning
Clean the chain saw thoroughly after each application so that
the faultless function is kept.
B
Clean the case with a soft brush or a dry cloth.
Water, solvents and polishing agents shall not be
applied.
B
Pay attention to that the ventilation slots for the motor
cooling are free (risk of overheating).
B
In case of harder pollution or resins put the chain for some
hours in a container with chain cleaner. Afterwards wash up
the chain with clear water.
B
Remove all adhering substances with a brush from the chain
wheel (13) and the sword fastening.
