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:
:
Move the choke lever to
g
:
Release screw
(1)
and remove the
filter cover
(2)
.
:
Clean away loose dirt from around
the filter.
:
Remove the foam element
(3)
.
:
Remove the metal screen
(4)
from
the filter housing
(5)
only
if it is dirty.
:
Knock out the filter element and
metal screen on the palm of your
hand, blow out with compressed air
or, if necessary, wash in a clean,
non-flammable solution (e.g. warm
soapy water) and then dry.
