directly the rear wheel through clutch. cush

drive and gear box.

Engine to wheel transmission ratios:

Third: 4.85 to I

Clutch. Multiplate. with lining adhering to

the driving discs (see Fig.4).

Control by lever, on left hand side of handle-

bars (see Fig. 8), and adjustable cable.

Gear box. 3-speed drive with mesh gears

in oil bath (see Fig.4).

Its adjustable twistgrip control is coupled

with that of the clutch, on left hand side

of handlebars (see Fig.8).

Starting. By means of klckstarter, right

hand side of scooter. The multiplate gear

and consequently the engine are set in

motion through a ratchet sector and a gear

by operating the klckstarter.

Cooling effected at all engine speeds by a

centrifugal fan (see Fig.7).

Silencer. Expansion and absorption com-

bined type with very high silencing efficiency.

Air cleaner mounted Inside the body. Air

goes to the carburettor through a large

flexible inlet tube, a silencing chamber and

porous filter, which ensure a very quiet air

Intake.

We recommend not to alter the silencer and the air cleaner

but to keep them in perfect efficiency, in order that the

noise level does not exceed the limits prescribed bylaw.

control cables and electric wires, to be con-

nected to the handlebars, are concealed inside

them (see Fig.8).

Speedometer. The speedometer is housed

in the central portion of the handlebars,

and adds to the performance and appearance

of the scooter.

It is driven by the front wheel, the flex

drive being completely enclosed in the

steering column.

WIRING

Either alternating or direct current for both

horn and lighting system is supplied as

follows (see Fig. 11. page 16).

- Main and dipped beam, tail lamp and

horn are directly fed with a. c. by the

six-pole flywheel magneto (nominalvoltage:

6 V).

14-

--I

- Parking lights, front and rear, and the

Stop light are with d. c. by a 6V-7Ah

battery which i~re-charged by the flywheel

magneto through a metal rectifier.

- The 6V- 0.6W speedometer bulb is fed

with either a. c. or d. c.

The head lamp, 0 105mm (4.13"), installed

in the handlebars. has a 25/25 W double

filament bulb (main and dipped beam),

and with a 3 W bulb (pilot light and par-

king light).

The tail lamp, with red reflector. has a 3 W

bulb which also illuminates the number

plate. The light and dip switch unit with ,.

. ':..~:.., ~~'

levers is installed on the right hand : '/J' ~

of the handlebars (see Fig. 11) ; one

the control levers has three positions:

- pilot light and tail lamp on;

-lights off;

- head lamp and tail lamp on;

the other one gives the two light conditions

of the head lamp (main and dipped beam

with tail light).

The switch has also two push buttons for

cut-out and horn respectively.

out by any customer, even inexperienced, by following some general rules. .

OPERATION

FUEL to be used during and after running-

in should be a 2% mixture of oil and petrol,

* pint oil per It gallons petrol respec-

tively. (Seelubrication chart).

We recommend to use good quality. standard grade car

petrol, and to mix it with oillhoroughly. Keep the breather

of filling cap clean.

Running-in. Important rules to be followed

while running-in 2000 Km (1200 miles):

- Do not exceed following speeds:

1st gear: 15Km/h (9.5 mph)

2nd gear: 30 Km/h (19 mph)

3rd gear 50 Km/h (31 mph)

- Do not hold these speedsfor long periods

neither use full throttle up-hill.

- Change oil in the gear box and check

that nuts and bolts are not slack after the

first 1000Km (600 miles).

- Check that carburettor is well blocked

on crankcase so that no air infiltrations may

occur.

Starting the engine. See (Fig. 6) the three

positions of the tap: on, off, reserve.

Open the fuel tap, put the gear box in neutral

(Fig. 14-15)and the throttle in slow running

position, then depress the starting lever.

Lift the choke rod when the engine is cold;

push said rod back as soon as the engine

starts.
