Checking Chain Lubrication; Chain Brake - Stihl MS 150 TC Notice D'emploi

English

Checking Chain Lubrication

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".

Chain Brake

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.
Disengaging the Chain Brake
Pull the hand guard towards the
N
front handle until there is an audible
click – the chain brake is
disengaged.
NOTICE
Always disengage chain brake before
accelerating the engine (except when
checking its operation) and before
starting cutting work.
High revs with the chain brake engaged
(chain locked) will quickly damage the
powerhead and chain drive (clutch,
chain brake).
The chain brake is also activated by the
inertia of the front hand guard if the
kickback force of the saw is high
enough: The hand guard is accelerated
toward the bar nose.
The chain brake will operate only if the
hand guard has not been modified in any
way.
Checking Operation of the Chain Brake
Before starting work: Run engine at idle
speed, engage the chain brake (push
hand guard towards bar nose) and open
the throttle wide for no more than
