Checking Chain Lubrication; Chain Brake - Stihl MS 201 C-M Instruction Manual

13 Checking Chain Lubrication

STIHL recommends you use the STIHL filler noz‐
zle for chain oil (special accessory).
► Close the tank cap.
There must still be a small amount of oil in the oil
tank when the fuel tank is empty.
If the oil level in the tank does not go down, the
reason may be a problem in the oil supply sys‐
tem: Check chain lubrication, clean the oilways,
contact your dealer for assistance if necessary.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer.
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

0458-598-0121-C
14.1 Locking the Chain
– in an emergency
– when starting
– at idling speed
The chain brake is activated by pushing the hand
guard towards the bar nose with your left hand –
or by inertia in certain kickback situations:
14.2 Disengaging the Chain Brake
► Pull the hand guard back towards the front
handle.
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 – even if your left hand
is not behind the hand guard, e.g. during felling
cut.
The chain brake will operate only if the hand
guard has not been modified in any way.
