properly. Finally, tighten using the special
wrench at the right torque (see instructions on
the engine user and maintenance manual).
When assembling a new
spark plug, tighten by 1/2 turn after the spark
plug has compressed the sealing washer.
If you put back the old plug after having re-
moved it, tighten it by 1/4 turn after it has
compressed the sealing washer.
The spark plug must be
tightened firmly. A badly positioned spark
plug may become very hot and damage the
engine.
7.4.4 Voltage adjustment
At the time of testing, the generating set has
been set on 2800 rpm so that the right voltage
can be obtained at the output terminals.
Any setting adjustment must be authorized by us
and anyway performed by skilled personnel.
Adjust the voltage when the engine is hot, no
load is present and the generating set is running
(Fig. 24 Ref. 1).
Turn the screw clockwise to increase the engine
revs and hence the voltage.
Turn the screw counter-clockwise to diminish the
engine revs and hence the voltage.
