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.
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.
High speed needle H
The high speed needle H
influences the power, speed,
temperature and fuel con-
sumption 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 ma-
chine "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.
NOTE! For optimum setting of the carburetor, contact a
qualified servicing dealer who has a revolution counter at
his disposal.
MAINTENANCE
H
Correctly adjusted carburetor
A correctly adjusted carburetor 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 difficulties 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.
