Operating Instructions

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 the flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Wait for the engine to cool down. Drain
the fuel Kraftstofftank and store the
machine in a dry place. Check the
tightness of all accessible screws and
nuts (not adjusting screws) at regular
regulars and retighten as necessary.
