Checking Chain Lubrication; Chain Brake - Stihl MS 200 Instruction Manual

English
Checking Chain
Lubrication
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".

Chain Brake

Blocking the chain
– in an emergency
– when starting
– when idling
Press the hand guard towards the nose
of the guide bar with the left hand - or
automatically due to kickback: the saw
chain is blocked - and stops running.
Release the chain brake
N Pull the hand guard toward the
handlebar
The chain brake must be released
before opening the throttle (except
during functional checkout) and
before sawing.
Running the engine at high revs
with the chain brake engaged
(chain locked) will quickly damage
the shortblock and chain drive
(clutch, chain brake).
The chain brake is activated
automatically by a sufficiently strong
kickback – due to the mass inertia of the
hand guard: The hand guard shoots
forward toward the nose of the guide bar
– even if the left hand is not on the
handlebar behind the hand guard, for
example, when making a felling cut.
