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.
Shut off the engine.
N Push the slide control in the
direction of the arrow on the stop
symbol (h) to STOP-0.
If the engine does not start
Choke knob
If you did not turn the choke knob to e
quickly enough after the engine began to
fire, the combustion chamber is flooded.
N Turn the choke knob to e
N Set the slide control, throttle trigger
lockout lever and throttle trigger to
the starting throttle position and
start the engine by giving the starter
rope a brisk strong pull. 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 Pull off the spark plug boot (10).
N Unscrew and dry off 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. Connect the
spark plug boot (press it down
firmly).
N Move the slide control to START.
N Set the choke knob to e – even if
the engine is cold.
N Now start the engine.
Throttle cable adjustment
N Check adjustment of throttle cable –
see chapter on "Adjusting the
Throttle Cable".
Fuel tank run until 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 knob according to
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".
