Operating Instructions

English / USA

Cleaning the Air Filter

:Unscrew and dry off the spark plug.

:Open the throttle wide.

:Crank the engine several times with the starter to clear the combustion chamber.

:Refit the spark plug. Connect the spark plug boot (press it down firmly).

:Move the slide control to START.

:Set the choke knob to e– even if engine is cold.

:Now start the engine.

Throttle cable adjustment

:Check adjustment of throttle cable – see chapter on "Adjusting the Throttle Cable".

Tank run until dry

:After refueling, press the fuel pump bulb at least five times – even if bulb is filled with fuel.

:Set choke knob according to engine temperature.

: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 engine to run for a while at idle speed so that the heat in the engine can be dissipated by flow of cooling air. This protects engine- mounted components (ignition, carburetor) from thermal overload.

After finishing work

Wait for engine to cool down. Drain the fuel tank. Store the machine in a dry place. Check tightness of nuts and screws (not adjusting screws) at regular intervals and retighten as necessary.

Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.

If there is a noticeable loss of engine power:

:Set the choke knob to g

:Press in the tab (1) and remove the filter cover (2).

:Clean away loose dirt from inside the cover and around the filter (3).
