If the oil level in the tank does not go
down, the reason may be a problem in
the oil supply system: Check chain
lubrication, clean the oilways, contact
your dealer for assistance if necessary.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.

Checking Chain Lubrication
The saw chain must always throw off a
small amount of oil.
NOTICE
Never operate without chain lubrication.
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".
