•  Inspect chain every day for:

-   Visible cracks in rivets or links

-   Stiffness

-   Abnormal wear in rivets or links

-   Min. 3 mm (1/8”) horizontal  cutter length

-   Any deviation on any of these points indicates a worn 

chain which must be discarded

-   Check the guide bar’s oil passage 

and clean if  necessary.

- 

  Check guide bar groove and 

clean if necessary.

-   Ensure that the nose sprocket 

turns easily and is not  clogged. 

Clean and grease if necessary.

•   The chain and bar are lubricated by an automatic oiling 

 system. We recommend using only chain saw oil, which is 

formulated for good adhesion and fl ow characteristics in hot 

or cold weather. Nonetheless, it is important to use the vis-

cosity  appropriate to the season. Oil thickens in  subfreezing 

temperatures and can overload the oil pump and cause 

parts to fail.

•   As a manufacturer of chain saws, we have developed an 

ideal chain oil which, being based on vegetable oils, is 

completely biodegradable. We recommend our oil for the 

sake of your chain and guidebar and for the sake of the 

environment.

•   Where chain oil is not available, EP 90 gear oil may be used.

•   If you need help choosing chain oil, contact your service dealer.

•  

Never use old motor oil! Used motor oil contains  impurities 

which may be harmful to oil pump, guide bar and chain.

•   All our chain saw models feature automatic chain l ubrication.

•   Start the chain saw and point the guide bar towards a fi xed, 

light- coloured object at a distance of  approximately 20 cm. 

After  running the saw for a minute, a streak of oil spatter 

should be clearly visible on the light surface.

•   A full reservoir is suffi cient for 20 minutes of steady use.

•   If the lubrication system does not seem to be working, and 

the following steps do not help,
