13 Checking Chain Lubrication

13 Checking Chain Lubrica‐
tion
The saw chain must always spin off a small
amount of oil.
NOTICE
Never operate your machine without chain lubri‐
cation. If the saw chain runs dry, the cutting
attachment may very quickly be damaged
beyond repair. Before starting work, always
check the chain lubrication and oil level in the
tank.
Every new saw chain needs a run-in time of 2 to
3 minutes.
After the saw chain has run in, check the tension
of the chain and correct if necessary – see
"Checking the chain tension".

14 Chain Brake

14.1 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 –
0458-599-0121-C
or by inertia in certain kickback situations: The
chain is stopped and locked.
14.2 Disengaging the Chain Brake
► Pull the hand guard towards the front handle
until there is an audible click – the chain brake
is disengaged.
NOTICE
Always disengage chain brake before accelerat‐
ing the engine (except when checking its opera‐
tion) 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 acceler‐
ated toward the bar nose.
The chain brake will operate only if the hand
guard has not been modified in any way.
14.3 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 3 seconds – the chain must not
rotate. The hand guard must be free from dirt
and move freely.
14.4 Chain Brake Maintenance
The chain brake is subject to normal wear. It is
necessary to have it serviced and maintained
regularly by trained personnel. STIHL recom‐
mends that you have servicing and repair work
carried out exclusively by an authorized STIHL
servicing dealer. Maintain the following servicing
intervals:
