N If your cap is in the closed position:
with the filler cap in the filling neck,
twist it counterclockwise until it
drops into its seat.
N Continue to twist the filler cap
counterclockwise (approx. 1/4 turn)
– this will twist the base of the cap
into the correct position for
installation.
N While pushing down on the cap,
twist the filler cap clockwise and
close it – see section "Closing."
Checking oil level
N Check the oil level regularly during
operation.
N Refill the oil tank when the oil level
reaches the "min" mark (1) or
earlier.
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 and
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".
