The idle speed should be checked
during a service.
Tachometer
502 71 14-01

sensing.
Adjust outdoors
The blade should be fitted.
– Run the machine warm for
approximately 5 minutes.
– Align the arrow towards the
spark plug
– Adjust to an idle speed of
approximately 2700 rpm.
– If the blade rotates, lower the

fied.
Valve axles
Leakage from the valve axles results in
incorrect fuel/air mixture and to dust
penetration in the engine.
Check that there is no radial play on the
valve axles. Replace parts if neces sary. See
the spare parts list.
Adjustment
The high and low jets on the carburettor
have been set at the factory. These should
not be readjusted.
Idle speed
The idle speed adjustment is the only car-
burettor adjustment that can and should
be made during a service. The idle screw
mechanically affects the opening of the
throttle valve.
The hole for the adjuster screw is next
to the cover for the fuel. Use the special
screwdriver (501 60 02-03).
Tachometer 502 71 14-01
The instrument is induction sensing and
does not need to be connected directly to
the ignition lead. The air filter cover can
be fitted when testing.
The supplied antenna cable does not
normally need to be used.
Adjust outdoors
Naturally the idle speed must be adjusted
outdoors on account of the exhaust
fumes. The blade should be fitted.
– Run the machine warm for approxi -
mately 5 minutes.
– Keep the instrument with the arrow
directed downwards towards the position
of the spark plug.
– Adjust the idle screw to an idle speed
of approximately 2700 rpm. The blade
should not rotate at this speed.
– If the blade rotates, lower the speed a
little. If this does not help the clutch
should be rectified.
