Final setting of the idling speed T
Adjust the idling speed with
the screw T, if it is necessary
to readjust. First turn the
idle speed adjusting screw
T clockwise until the cutting
attachment starts to rotate/
move.
Then turn, counter-clockwise
until the cutting attachment
stops. A correctly adjusted idle
speed setting occurs when the
engine runs smoothly in every
position. It should also be
good margin to the rpm when
the cutting attachment starts
to rotate/move.
High speed needle H
The high speed needle
H infl uences the power,
speed, temperature and fuel
consumption of the machine.
A too lean adjusted high
speed needle H (high speed
needle H closed too much)
gives overrevs and damages
the engine. Do not let the
machine run at full speed for
more than 10 seconds.
Turn the high speed needle
very slowly clockwise until
engine speed is reduced.
Thereafter turn the high speed
needle very slowly counter-
clockwise and stop when the
engine begins to run roughly.
Then turn the high speed
needle slowly the minimum
amount clockwise until the
engine runs smoothly.
The high speed needle H
is correctly set when the
machine ”4-cycles” a little. If
the machine ”whistles” the
setting is too lean. If there
is too much smoky exhaust
gas at the same time as the
machine ”4-cycles” much, the
setting is too rich.
MAINTENANCE
CAUTION! Contact your servicing dealer, if the idle speed
setting cannot be adjusted so that the cutting attachment
stops. Do not use the machine until it has been properly
adjusted or repaired.
NOTE! For optimum setting of the carburettor, contact a
qualifi ed servicing dealer who has a revolution counter at
his disposal.
Correctly adjusted carburettor
A correctly adjusted carburettor means that the machine
accelerates without hesitation and the machine 4-cycles a little
at max speed. Furthermore, the cutting attachment must not
rotate/move at idling. A too lean adjusted low speed needle L
may cause starting diffi culties and bad acceleration.
A too lean adjusted high speed needle H gives lower power =
less capacity, bad acceleration and/or damage to the engine.
A too rich adjustment of the two speed needles L and H gives
acceleration problems or too low working speed.
