There must still be a small amount of
chain oil in the oil tank when the fuel tank
is empty.
If the oil tank is still partly full, the reason
may be a problem in the oil supply
system: Check chain lubrication, clean
the oil passages, contact your servicing
dealer for assistance if necessary.
STIHL recommends that maintenance
and repair work be carried out only by
authorised STIHL dealers.

Checking Chain Lubrication

The saw chain must always throw off a
small amount of oil.
NOTICE
Never operate your saw 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".
