N Pull the hand guard toward the
handlebar
The chain brake is released – the chain
saw is ready for use.
Open the throttle only when the
chain brake is off. Increased
engine speeds with the chain
brake on (saw chain is stationary)
lead to damage to the clutch and
chain brake.
At very low outside temperatures
N let the engine warm up briefly with
the throttle slightly open
Switch off engine
N Move the Master Control lever to the
stop position 0
N if necessary, configure for winter
operation, see "Winter Operation"

Operating Instructions

During break-in period
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessary high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see "Adjusting the
Carburetor".
Always disengage chain brake
before accelerating the engine.
Running the engine at high revs
with the chain brake engaged
(chain locked) will quickly damage
the engine and chain drive (clutch,
chain brake).
During Operation
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
