Take care not to spill chain oil while
refilling and do not overfill the tank.
STIHL recommends use of the STIHL
filling system for chain oil (available
option).
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 tank is still partly full, the reason
may be a problem in the oil supply
system: Check chain lubrication, clean
the oil passages, contact a servicing
dealer if necessary. STIHL recommends
that maintenance and repair work be
carried out only by authorized STIHL
dealers.
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".
Locking the chain
– in an emergency
– when starting
– at idling speed
The chain brake is activated by pushing
the hand guard toward the bar nose with
your left hand – or by inertia in certain
kickback situations: The chain is
stopped and locked.
