WARNINGt
The machine
must only be started as a
complete
unit. If the machine
is started
without
all the covers fitted there is a risk
of personal
injury.
Operation
• The carburettor governs
the engine's speed via the
throttle. Air/fuel is mixed
in the carburettor. The
air/{uel mixture is
adjustable. To take
advantage o_'the engine's
optimal output the
adjustment must be
correct.
• The setting of the
e_trburertor means that
the engine is adapted to
local conditions, for
example, the climate,
altitude, petrol and the
type of 2-st_:oke oil.
Basic setting
• The carbureetor is set to its basic setting when test run at the
l]_cto U. The basic setting is richer than the optimal setting
and should be kept during the machine's first working
hours. Thereafter the earburertor should be finely adjusted.
Fine adjustment should be carried out by a skilled
technician.
Fine adjustment
• When the machine has been "run-in" the carburettor should
be finely adjusted. The fine adjustment
should be carried
out by qualified person.
First adjust the L-jet, then the
idling screw "l' and then the H-jet.
Conditions
• Before any adjustmems
are made the ah:filter should be clean
and the airfilter cover fitted. Adjusting the earburettor while
a dirty airfilter is in use will result in a leaner mixture when
the filter is finally cleaned. This can give rise to serious
engine daurage.
