MAINTENANCE
CLEANING
Regularly clean the tensioning mechanisms by blowing compressed air onto it or by cleaning it with a brush. Do
not sue any tools for the cleaning.
Keep the oil away from the handle in order to ensure a secure hold.
Clean the machine as necessary with a damp cloth and a mild cleanser, if appropriate.
If the chainsaw is not used for an extended period of time, remove the chain oil from the tank. Briefly place the
chain and the guide bar in an oil bath and then wrap in oil paper to dry.
Always replace the protective cover for tranport or storage of the chainsaw. Secure the tool during transport to
avoid damage or injuries. Unplug the power supply before cleaning. Never immerse the machine in water or other
liquids. Store the chainsaw in a safe and dry area away from children.
REPLACING THE SAW CHAIN AND GUIDE BAR
The guide bar must be replaced if the groove of the guide is worn out or the spur wheel in the guide bar is dam-
aged or worn out.
CHECKING THE AUTOMATIC CHAIN LUBRICATION
Regularly check the functionality of the automatic chain lubrication in order to prevent overheating and the subse-
quent damage to the guide bar and saw chain associated with it. For this purpose, align the guide bar tip against a
smooth surface (board, cut-in of a tree) and allow the chainsaw to run. If an increasing amount of oil appears, the
automatic chain lubrication functions properly.
