WARNING
Injuries hazard, because of the motion of blower
blades, belts and of hot components of the engine
and silencer.
Shut off the engine and let it cool down, before
opening the engine compartment.
Place the machine in a safe condition.
Shut off the engine.
Open the engine compartment cover. The engine
revolutions sensor (1) is fitted on the flywheel case
and is accessible from the bottom, after dismantling
the panels, that are placed under the pumps and
engine compartment.
Disconnect the connector of the sensor linkage
cable.
Loosen the lock-nut (2) and unscrew the sensor (1).
Clean the front side of the sensor.
Check the electric contacts of connector. If neces-
sary, clean them and remove rust, if present.
To reassemble the sensor, carry out following opera-
tions:
Screw up sensor (1) manually in the fly-wheel case,
until a certain hardness is felt. Now the front face of
sensor is going to lean against the fly-wheel tooth.
Now unscrew the sensor of half a turn. In this way
the correct distance of the fly-wheel is set.
Tighten the lock-nut (2), paying attention not to mod-
ify the sensor tightening depth.
Connect again the connector of the linking cable.
