Stopping the engine
N Move the slide control in direction of
the arrow (h) to STOP-0 or the stop
switch to STOP / 0.
If the 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 Set the slide control, trigger lockout
lever and throttle trigger to 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 Move the slide control or stop switch
to STOP / 0.
N Remove the spark plug – see
"Spark Plug".
N Dry the spark plug.
N Crank the engine several times with
the starter to clear the combustion
chamber.
N Refit the spark plug – see "Spark
Plug".
N Move the slide control or stop switch
to F / I.
N Set the choke lever to e – even if
the engine is cold.
N Now start the engine.
Fuel tank run until completely dry
N After refueling, press the fuel pump
bulb at least five times – even if the
bulb is filled with fuel.
N Set the choke lever to suit the
engine temperature.
N 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 perionds – see "Storing the
Machine".
