Preparations
N Thoroughly clean the oil filler cap 
and the area around it to ensure that 
no dirt falls into the tank.
N Position the machine so that the 
filler cap is facing up.
N Open the filler cap.
Filling chain oil tank
N Refill the chain oil tank every time 
you refuel.
Take care not to spill chain oil while 
refilling and do not overfill the tank.
N Close the filler cap.
There must still be a small amount of oil 
in the oil tank when the fuel tank is 
empty.
If the oil level in the tank does not go 
down, the reason may be a fault 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.
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".
