If the oil level in the tank does not go down, the
reason may be a problem in the oil supply sys‐
tem: Check chain lubrication, clean the oilways,
contact your dealer for assistance if necessary.
STIHL recommends that maintenance and repair
work be carried out only by authorised STIHL
dealers.

10 Checking Chain Lubrica‐
tion
The saw chain must always throw off a small
amount of oil.
NOTICE
Never operate your machine without chain lubri‐
cation. If the chain runs dry, the whole cutting
attachment will be irretrievably damaged within a
very short time. Always check chain lubrication
and the oil level in the tank before starting work.
Every new chain has to be broken in for about 2
to 3 minutes.
After breaking in the chain, check chain tension
and adjust if necessary – see "Checking Chain
Tension".
