Headlight adjustment
Proceed as follows:
1. Position the unloaded vehicle, in running order
and with the tyres inflated to the prescribed pres-
sure, on a flat surface 10 m away from a half-lit
white screen; ensure that the longitudinal axis of
the vehicle is perpendicular to the screen;
2. Turn on the headlight and check that the bor-
derline of the projected light beam is lower than
9/10 and higher than 7/10 of the distance from the
ground to the centre of the vehicle headlight;
3. If not, adjust the headlight by turning the central
screw «A» placed behind the Piaggio badge.
N.B.
THE ABOVE PROCEDURE COMPLIES WITH THE EURO-
PEAN STANDARDS REGARDING MAXIMUM AND MINI-
MUM HEIGHT OF LIGHT BEAMS. REFER TO THE STATU-
TORY REGULATIONS IN FORCE IN EVERY COUNTRY
WHERE THE VEHICLE IS USED.
Checking the end compression pressure
- Remove the spark plug hood with cold engine.
- Remove the ignition spark plug.
- Fit a compression test gauge into the spark plug seat using a 10 mm spark plug coupling, at the proper
locking torque.
- Set ignition switch to «ON», wait a few seconds and then disconnect the revolution timing sensor
connector in order to deactivate the injector and the spark plug.
- Let the engine run using the starter motor and with the throttle body in fully open position until the
gauge value is steady.
- If the pressure is higher than the indicated, remove the tool and proceed to refit to the vehicle.
- If the pressure is lower than indicated, check the rpm at which the test is carried out; if lower than 450
g/1', check the start-up system.
