Checking chain wear
• 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 pas-
sage 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.
Chain oil
• 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 weath-
er. Nonetheless, it is important to use the viscosity 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.
Filling chain oil
• All our chain saw models feature automatic chain l ubrication.
Checking automatic chain lubrication system
• Start the chain saw and point the guide bar towards a fi xed,
light- coloured object at a distance of approximately 20 cm. Af-
ter running the saw for a minute, a streak of oil spatter should
be clearly visible on the light surface.
CHAIN AND GUIDE BAR LUBRICATION
CAUTION!
Inadequate lubrication can lead to cutting equipment failure and serious or fatal
personal injury.
• 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, take your saw to a service
dealer.
