Place the scooter on a level floor in front of
a white wall as seen in Fig. 19. Start the
engine, hold the throttle control twistgrip
at about 1/3 and set the switch on "mai n
beam."
With two persons on the Vespa, slacken the
set screw securing the head lamp, then move
the latter as required in order that the beam
axis coincides with point "0" on the wall.
--
Tighten the screw firmly.
\1
This operation can be carried out also with the
driver only sitting on the seat.
In this case, of course, the beam alignment
should be altered whenever the scooter is
being ridden by both driver and passenger.
