Chain lubrication
The saw chain and saw guide must be lubricated during operation in order to avoid major
wear and tear. Chain lubrication is automatic. Never use the chainsaw without a functioning
lubrication. Both the saw guide and saw chain can be damaged very quickly without lubrica-
tion; that is why it is important to check the chain lubrication function and oil tank level with
every use (fig. 7)
Never use a chainsaw if the oil level is under
MIN
.
•
Min:
When the oil level is under
MIN
or 5 mm at the lower part of the window in the oil
tank (15), fill up with chain oil.
•
Max:
Fill with chain oil until the whole window is full.
Checking chain lubrication
Check the lubrication of the chain as follows: start the chainsaw and hold the guide approxi-
mately 20 cm above a piece of wood or other lightly coloured object. If the lubrication is func-
tioning properly, the oil will splash from the chain and be seen on the lightly coloured object.
If no traces of oil are seen you should clean the outflow hole (C) and the upper tension hole
in the guide (D), see fig. 2, or contact the retailer or service station. Be careful not to allow the
chainsaw to touch the ground during testing.
Chain oil
The life expectancy of the chain guide and saw chain depends on which chain oil is used.
Only use chain oil and never spilloil etc. Use environmentally friendly types of chain oil, store
the chain oil in a container designed for chain oil.
Saw guide
The saw guide (7) wears down the most on the tip and on the underside; turn the guide, when
the chain is being sharpened so that it wears on both sides. File away eventual burrs on the
saw guide with a flat file.
Chain drive
The chain drive (17) is subject to extreme wear; check for marks, wear or disfigurement. Re-
place chain if required. Be warned, the chain drive will wear down a new saw chain quickly.
Contact the retailer service station to replace the chain drive.
Guide guard
Put back the guide guard straight away when you have finished sawing and always when the
chainsaw is to be stored or transported.
Kick back guard/chain brake
In the event of kick back from the saw guide the chain brake will be activated by the kick back
guard (3) by being pushed forward by the handle switching the motor off in 0.15 of a second (fig. 3).
