N
Blip the throttle trigger to disengage
the starting throttle position. The
slide control moves to the normal
run position
F
– and the engine
settles down to idle speed.
N
Open the throttle slightly and warm
up the engine for a brief period.
If engine does not start
Choke lever
If you did not move the choke lever to
e
quickly enough after the engine began to
fire, the combustion chamber is flooded.
N
Set the choke lever to
e
.
N
Select the starting throttle position.
N
Start the engine by pulling the
starter rope briskly – 10 to 20 pulls
may be necessary.
If the engine still does not start
N
Push the slide control in the
direction of the arrow on the stop
symbol (
h
) to STOP
-
0.
N
Remove the spark plug – see
"Spark Plug".
N
Dry the spark plug.
N
Open the throttle wide and pull the
starter rope several times to clear
the combustion chamber.
N
Refit the spark plug – see "Spark
Plug".
N
Move the slide control to START.
N
Set the choke lever to
e
– even if
the engine is cold.
N
Now start the engine.

N
Set the choke lever to suit the
engine temperature.
N
Now start the engine.
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.
During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat can be dissipated by the flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Storing for a short period: Wait for the
engine to cool down. Empty the fuel tank
and keep the machine in a dry place,
well away from sources of ignition, until
you need it again. For longer out-of-
service periods – see "Storing the
Machine".
