Due to the simple and conventional design of the
Allstate scooter, no particular skill is required for its
operation, nor skilled personnel for its maintenance.
The tasks can be quite well carried out by .,ny
customer, even inexperienced, by carefully following
some general rules.
Running- in. - Important rules to be followed while
running. in (1200 miles) :
Do
not exceed following speeds:
1st gear 13 mph.
2nd gear 19 mph.
3rd ge1H 25 mph.
4th gear 37 mph.
Do not hold these max speeds for long periods neither
use full throttle opening up - hill.
Change oil in the gear box and check thl!lt nuts and
bolts are not slack after the first 600 miles.

S. A. E. 30.
With the help of ., pilot wire slide the sheath cA ~
for the flex drive, into the steering column, from
the top end, until it emerges from the bottom end
(indicated with an arrow in the figure).
Pull the pilot wire out of the sheath, grease the flex
drive generously and slide it in.
Assemble packing cC ~ and then the speedometer
head cB ~ on the bracket E, already mounted with
rubber buffer cF ~ fixing with the apposite screw
cU ~ and spring washer cT ~ ensuring that said
screw is not tightened too firmly to avoid deformation
of the speedometer head.
Insert the upper end of the flex drive into housing
in the speedometer head and secure both flex drive
and sheath by means of knurled ring nut cG ~.
Now secure the group speedometer and bracket to
the handlebars by means of the screw cS ~ and
plain washer cR ~.
Completed the above operations reassemble the head·
lamp.
Fill up hub with grease in order to lubricate the
portion of the wheel spindle meshing with the spee-
dometer drive pinion cI ~.
Mate the pinion cI ~ to the support bush cL ~, then
mount ring (with lubricator) cK ~ on the latter;
screw the support bush cL ~ on the wheel hub. If an
axial play between drive pinion and centre pin of
0.25 to 0.8 mm. (0".01 to 0".03) is not obtained on
assembling the part cL ~ into the hub, interpose the
spacer washer cM ~.
Slide the rubber cap cN ~, the threaded ring c0 ~
and biconical ring cP ~ over the sheath end; fit the
washer cQ ~ on the cable portion which protrudes
from the sheath, P.,ss the I.,tter between the front
brake control cable .,nd the wheel, then screw and
tighten threaded ring c0 ~ on bush cL ~ and po-
sition rubber cap cN ~.
Ensure that the end of the flex drive is accurately

Keep the breather of filling cap clean.
Fuel $upply .. Fuel mixture, both during and after
running in, should be composed of regular gasoline
and pure mineral oil SAE 30 at 2%, i. e.:
- If.I. pint of oil 1% gallons of gasoline.
When using pre - diluted or additive oils, or oils for
outboard motors, mix 1,4 pint of oil per gal.
Oil level. -Remove the level screw, on crankcase,
marked c OLIO ~ as indicated on page 11 Fig. 20, to
check oil level in gear box before starting the engine.
The scooter standing upright, oil should just be about

Stlrtinlil· . Open :ne fuel valve, put the gear", box
in neutral and slightly open the throttle in slow running
position, kick the starting lever.
With cold engine, operate starter push pull rod.
Push said rod back as soon as the engine fires.
See Fig. 11 ; note the three positions of the fuel valve:
open, closed, reserve.
C.ution .. Do not open throttle wide when releasing
clutch.
In case of starting troubles, due to engine being
flooded (unvaporized fuel mixture has reached the cy.
linder and combustion becomes therefore very difficult),
proceed according to either one of the following methods:
a) Push· start the scooter: shift into second gear,
declu ch and push the machine; quickly release the
clutch lever and pull it back as soon as the engine starts.
b) Close the fuel cock, remove the spark plug and
rotate the engine by means of the kickstarter. Wipe the
plug dry and replace. Open the fuel cock and kick the
starting lever.

For acceu to the engin., take off the engine cowlin~
then proceed as follows.
Pull the lever «1 ~ (Fig. 13) and turn it so as to
release
it from bonnet. Then move the bonnet slightly
outwards, until front pivot t( 2 ~ is extracted from
the hole on the frame.
Push the bonnet from the front upwards and turn it
(see position indicated by dotted line), thus releasing
the
fixing hook «3 ~ from frame.
Move bonnet outwards round its hooked pivot «4 ~
until the latter disengages from the hole on frame.
Thus the bonnet is removed.
For re - assembly, follow the reverse procedure.
Setting the machine in motion. - Let the engine idle,
depress the clutch and turn the gear change twistgrip
so that the line engraved on it coincides with the figure
«1 ~ (1st gear) engraved on handlebars (see Fig. 14).
Now let in the clutch gently, while opening the throttle
gradually to set the machine in motion.
Gear change. - On attaining the required speed in
1
st gear, quickly close the throttle, release the clutch
and turn the gear change twistgrip so that the engraved
line coincides with figure «2 ~ (2nd gear); let in the
clutch and open the throttle.

Repeat this procedure for changing into 3rd and

See the drive system on Fig. 14.
When you reduce the speed of your machine, change
down without delary to avoid irregular engine running
and stalling at low revs.

Do not turn the gear change twistgrip while the
engine is not running.
As soon as gear change troubles arise, particularly
when the control becomes hard, customers should have
their machines adjusted by aSears Store.
Slow running adjustment •• No hand tool is requir.
ed for this job. Idling revs can be raised or reduced
respectively by simply tightening or slackening the
knurled slotted screw on air cleaner steel sheet cover
(No.5, Fig. 11). This screw controls the throttle slide
valve.
The adjuster screw for the throttle control cable is
installed on the air cleaner case. This screw is to be
reset only when necessary and while dismantling and
re • assembling. Opposite to said adjuster screw there is
on the air cleaner case a plugged hole for access to
another screw (spring loaded); see Fig. 11 No. 14.
This
screw controls the flow of carburated air through
the duct from the idling jet, and consequently the idling
revs. We recommend that customers refrain from re-
setting this screw unless absolutely necessary or during

dismantling and re - assembling operations that should.
anyway, be entrusted to a Sears Store.
Stopping the engine .. Push the earthing button.
This will leave the cylinder full of fuel vapours, and the
next start will be much easier.
Tires. -The wheels are interchangeable, i. e. they
can be assembled either in front or rear, provided of
course that they are inflated to pressures respectively
hereunder prescribed.
When aflat tire is to be replaced, unscrew the four
nuts which secure the wheel to its flange, pull wheel
sideways off the studs (see Fig. 15), repair it or replace
with spare wheel.
To remove the tube, first deflate, then separate the
felloe from the ring by unscrewing the nuts which join
them (see Fig. 16).

Br.ke .djustment. - Brakes are properly adjus ed if:
the wheel rotates freely when respective control le-

the braking action starts as soon as respective con-
trols are operated.
These conditions are achieved adjusting the cables
by means of screws indicllted with an arrow in Fig. 17.
