Checking Chain Lubrication; Chain Brake - Stihl MS 280 C Instruction Manual

English / USA

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
oil level in tank before starting work.
Every new chain has to be broken in for
about 2 to 3 minutes.
After breaking in chain, check chain
tension and adjust if necessary – see
"Checking Chain Tension".

Chain Brake

The chain brake system on your saw
has two functions:
: Standard STIHL chain brake and
: STIHL rear-handle-activated
secondary braking system
The standard STIHL chain brake utilizes
the front hand guard as the activating
mechanism and is designed to stop the
chain within fractions of a second. The
secondary braking system, on the other
hand, is designed to stop chain rotation
within a second of you completely letting
go of the rear handle.
To reduce the risk of personal injury or
property damage during cutting,
observe the characteristics that make
this saw different from saws not
equipped with a rear-handle-activated
brake. Before operating the chainsaw for
the first time, make sure you are familiar
with how secondary braking system
works. See chapter "Starting/Stopping
the Engine".
Secondary chain brake activated
by throttle trigger interlock
: When you let go of the rear handle,
including the throttle trigger
interlock lever.
Disengaging the secondary chain
brake
: Press down the throttle trigger
interlock lever. This releases the
clutch drum and allows the chain to
rotate.
