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
Storing for short period:
Wait for engine to cool down. To avoid
condensation, fill the fuel tank and keep
the unit in a dry place until you need it
again.
Storing for a long period:
see chapter "Storing the Machine".
For periods of about 3 months or
longer
: Remove the blower tube and
nozzle.
: Drain and clean the fuel tank in a
well ventilated area.
: Run engine until carburetor is dry -
this helps prevent carburetor
diaphragms sticking together.
: Thoroughly clean the machine - pay
special attention to the cylinder fins
and air filter.
: Store the machine in a dry, high or
locked location - out of the reach of
children and other unauthorized
persons.
