Checking Chain Lubrication; Chain Brake - Stihl MS 880 Manual De Instrucciones

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

Locking chain with chain brake
– in an emergency
– when starting
– at idling speed
The chain is stopped and locked when
the hand guard is pushed toward the bar
nose by the left hand – or when brake is
activated by inertia in certain kickback
situations.
Releasing the chain brake
N
Pull the hand guard back toward the
front handle.
Always disengage chain brake
before accelerating engine and
before starting cutting work. The
only exception to this rule is when
you check operation of the chain
brake.
High revs with the chain brake
engaged (chain locked) will
quickly damage the powerhead
and chain drive (clutch, chain
brake).
The chain brake is designed to be
activated also by the inertia of the
front hand guard
if the forces are sufficiently high. The
hand guard is accelerated toward the
bar nose - even if your left hand is not
behind the hand guard, e.g. during a
