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 authorized STIHL dealers.

Checking Chain
Lubrication
143BA024 KN
The saw chain must always throw off a small amount of oil.
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".
