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”.
Locking chain with chain brake
– in an emergency
– when starting
– at idling speed
The chain is stopped and locked when
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
: 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).
