►
Set the choke lever to e .
► Set the slide control, trigger lockout lever and
throttle trigger to the starting throttle position.
► Start the engine by pulling the starter rope
briskly – 10 to 20 pulls may be necessary.
13.5.1 If the engine still does not start
► Move the slide control or stop switch
to STOP / 0.
► Remove the spark plug – see "Spark Plug".
► Dry the spark plug.
► Crank the engine several times with the starter
to clear the combustion chamber.
► Refit the spark plug – see "Spark Plug".
►
Move the slide control or stop switch to F / I.
►
Set the choke lever to e – even if the engine
is cold.
► Now start the engine.
13.5.2 Fuel tank run until completely dry

bulb at least five times – even if the bulb is fil‐
led with fuel.

14 Transporting the Unit
14.1 Using transport guard
The type of transport guard depends on the
metal cutting attachment supplied with the
machine. Transport guards are available as spe‐
cial accessories.

15 Operating Instructions
15.1 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 dur‐
ing 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.
15.2 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.
