THE AUSTIN SEVEN
T
HE Austin Seven is acknowledged to be the best small car in the
world.
It is designed lor, and will carry in comlort, lour adults up to a
weight 01 40 stones and 56 Ibs. 01 luggage.
There are live models made, the Cabriolet, the de luxe Saloon, the Saloon with lixed head, the Tourer and the Two-Seater. The closed models are alike in general lines and general equipment. Particularly
good leatures are the wide doors and the lour side windowswhichare ~
mechanically raised or lowered.
The large single panel windscreen, which can be opened wide and secured by an ingenious lever lastening easily reached from the driver's scat, is another advantage. The Tourer, with its easily operated hood, and side curtains which open with the doors, provides complete protection
in even the most inclement weather. '
Both Iront seats are separately adjustable. They tilt lorward and allow ready access to the rear seats or luggage space.
The Austin Seven has a 4-cylinder, water-cooled engine, synchromesh gears, and bevel drive. Lubrication is by pump, and cooling is on the thermo-syphon system assisted by lan.
The complete equipment includes electric starting and lighting switches, loot operated "dip and switch" lor headlamps, air strangler, electric horn, speedometer, electric windscreen wiper, automatic return direction indicators, licence bolder, shock absorbers. spare wheel and
4
,
tyre and blank 'number plates. All littings are chromium plated, except the wheel centres, which are 01 stainless steel.
The Austin Seven is particularly suitable lor the woman driver. It requires little physical ellort to drive and control, and lor that reason its use enables her to do shopping calls without latigue, visit her lriends, attend social and other !unctions, or make excursions or trips in any' direction in any weather.
For the same reasons business men lind it an excellent vehicle, and commercial travellers and others whose occupation compels Irequent calls
over an extended area have in the little car an embodiment 01 all they require. Calls can be made in places where trains, trams and 'buses are inlrequent.
In large establishments, where the instant use 01 a car is 01 vital
importance in cases 01 emergency, such as sudden illness or accident, the Seven has been installed as a "tender," and in addition to its superiority
over large unwieldy cars lor short runs, has proved a real time and money saver.
As40-42miles per gallon is the average petrol consumption, the cost 01
transit is below the cost 01 lares on any public conveyance.
Its speed, economy, reliability and road-holding qualities have been
admitted beyond dispute.
Many thousands of motorists have had their lirst experiences on a
"Seven"; thousands more will lollow them.
Having successlully passed through lilteen years 01 severe use and
trial, it has emerged a really success!ul and popular lavourite and its
splendid qualities are internationally recognized.

F you are not familiar with Austin cars
carefully.
Give the new car a general
examination to see that all is in order.
Before running, see the car is supplied with fuel and water, that the engine and gearhox have the neces- sary quantities of oil and that the
battery contains tbe proper amount
of acid.
Cars delivered by road are ready for running. There is no oil,
fuel or water in cars crated for over- seas and the batteries are empty and
uncharged.

a full supply of petrol.
.Give the engine a few turns with the starting handle to make sure that the crankshaft is free (pushing the handle in to engage fully with the starting nut, before turning it). The ignition key is turned to the right to switch on the ignition and the charging and lighting switch is turned
to "High" or "Low" Charge.

Never leave the ignition switch on for any lengthy period while the engine is not running. The warning lamp on the switch board will remind
you of this.
."
Difficulty in Starting.
, Difficulty in starting may he
caused either through 'sucking too much petrol into the cylinders, or too
little. When starting with the throttle all but closed, a strong suction takes effect on the slow running jet. If petrol is passing through the car-
huretter the suction can generally be heard.
Str_ler and Throttle Control.
A-No=.l po.I<ion. B-F.., Idlin"
C-W.=in, Up.
If the engine fails to start quickly and it is thought that the mixture getting into the cylinders may be too rich, the accelerator pedal should be depressed half-way to reduce the suction. On firing, the engine will race, and the throttle should be almost closed. If the engine does not fire, close
the throttle entirely, and try again. '
After a stop in hot weather, failure of the engine to start is more likely to be due to a too rich mixture than one too lean, and one should
switch off only after quite closing tbe throttle. Re-start tbe engine with the throttle closed.
Depress the clutch pedal before switching on. This ;"ill lessen the
starting load and help the starter to turn the engine at higher speed, as well as save drain on the batteries.
If after the foregoing measures have been carried out the engine fails
to start, the reason will probably be faulty ignition or carburation.
If faulty ignition is suspected, first examine the wires and see that the
sparking plugs are connected. Then test the gap of the plug points by means'
of the thick end athe gauge provided
in the tool kit. If the points are dirty, clean them.
If carburation gives trouble, the
slow running jet may be stopped up
or a main jet cboked. Blow them out orally or with a tyre pump. Never attempt to clean them by passing a wire or other small metal object through tlrem. This will definitely injure the jets.
The engine should never be
allowed to run at high speeds during
its first 500 miles.

Maximum desirable road speeds during the first 500 miles are:-
First gear, 7 m.p.h.: second gear, 11 m.p.h.; third gear, 18 m.p.h. and top gear, 30 m.p.h.
The Starting Handle (Fixed type).
When the engine is running, see that the starting handle is not hanging down. It should be replaced in a borizontal position at "9 o'clock." (See page 8).
There is a catch which will secure it in its proper place there on the
off-sideofthecar. '
The starting handle should be oiled occasionally.

THE INSTRUMENTS
Fuel and Oil Gauges, Speedometer,
Windscreen Wiper.
A
' FULL range 01 instruments is provided on all Austin Cars. They
are 01 the highest quality and the lollowing notes explain their uses,
Fuel Gauge.
The,luel gauge is electrically operated al)d automatically indicates the
approximate contents 01 the tank when the ignition control is switched on.
When the tank is being relilled, switch 011and stop the engine and
then switch on again and the needle will record the amount 01 spirit
entering the tank. The capacity is live gallons.
The gauge requires no attention.
I
Oil Gauge.
The oil gauge indicates that oil is being pumped through the engine lubrication system and it should be looked at frequently when the engine is running to ascertain that sullicient pressure is registered.
When the engine is cold high pressure will be recorded, but this is
likely to drop as the oil becomes warmer. If no pressure is registered the engine should be stopped and the cause 01 the lault ascertained. otherwise serious damage may be caused.
Flickering 01 the needle may indicate serious shortage 01 oil or a
damaged pipe line.
The gauge may indicate a pressure 0110 Ibs. or more when the engine
is cold or Irom 2 to 10lbs. when hot. With the engine running at constant speed the needle should be quite steady.
Windscreen Wiper,
The windscreen wiper is started by pulling out the handle and swinging
it aside to bring the wiper blade into position on the screen. Then move the switch to the lelt.
On stopping the wiper move the switch to the right and replace the
handle in the top 01 the switch knob so that the blade is held out 01 the driver's line 01 vision.
.
Ammeter.
The ammeter indicates the rate 01 discharge 01the batteries, but does
not indicate current used by the starter motor.
No discharge should be indicated with no electrical equipment in use or with headlamps on when the car is running at about 20 miles an hour (30 kms.), or laster.

Switch Box.
When the engine is not'in use the ignition key should be withdrawn
Irom the switchbox. It can be withdrawn only when the ignition is "off."
The lighting switch also controls the rate at which the dynamo charges
the battery. "High Charge" should be used in the Winter and when the car is used very little in the Summer. "Low Charge" is lor Summer use when the batteries are not used a lot lor lighting, or frequent starting. and
the car is used fairly frequently. Speedometer.
The figures on the speedometer record up to 100,000 miles or kilo.
metres and they automatically return io zero.
The flexible shaft of the speedometer drive from the gearbox should be
lubricated by oiling from the speedometer end every 2.000miles. To do this uncouple the union nut behind the speedometer.
The shafting should also be taken down and thoroughly cleaned every
6.000miles. It should be lubricated along its length by applying thin
grease so that when the shaft is replaced in its tubing there will be a good supply of lubricant.
Grease should also be smeared round the flange where it rubs the
washer of the key piece wh:ch connects to the speedometer.
Traflic Signals.
The trallic indicators are con.
trolled lrom the steering wheel. Normally. after the car has turned a
corner they automatically return. but when a slight turn has been made it may be necessary to switch olf.
Panel Lights.
The instruments are illumin.
ated by two lamps controlled by the same switch. The holders can be swung aside to facilitate removal of
the bulbs. whichin emergency can belitted to the side or combinedstop
and tail lamp.
Dip Switch.
The headlamp dipping switch has two lunctions, one to give the normal driving light and one to dip the near side head.lamp beam and at the same time switch 011 the ollside headlamp.
If the headlights are on lull, a touch 01 the loot on the switch alters the lamps to the "dip.and.switch" position and they remain so until
another touch returns them to the "lull on" position.
Continental headlamps have dual.filament bulbs and are dipped
in the same manner. Windscreen.
The windscreen is opened by lifting the handle and pushing it lorward.

CONTROL OF THE CAR
How to Change Gear; Some Good
Driving Hints
T
HE driving seat 01 the Austin Seven is adjustable lor position and
tbis convenience sbould be taken advantage 01 to obtain tbe greatest comlort.
To engage lirst gear, pusb out the clutcb and move tbe gear lever
into tbe lirst speed position. .
Sometimes it may bappen tbat wben tbe clutch is let in, tbere is no apparent drive Irom tbe engine. Tbat is because tbere bas been no proper engagement 01 tb, gears. Tberelore, pusb out tbe clutcb again,
and it will almost certainly be lound tbat tbe lever can then be moved so as to give tbe proper gear engagement witbout using any lorce.
Start on'lirst speed, accelerate to about 8 m.p.b., pusb out tbe clutcb,
move tbe lever to neutral, and continue tbe movement 01the lever steadily
to tbe second speed position and let in tbe clutcb gently. '
In moving from second to tbird speed, a similar action takes place. Accelerate to about 18 m.p.b., declutcb, release tbe accelerator, move tbe lever to neutral and continue tbe movement 01 tbe lever steadily into tbe tbird speed.
To move from tbird to top, declutch, and move tbe lever steadily into tbe position desired. It assists tbe cbange Irom top to third, and
tbird to second il tbe accelerator is held down while the change is made.
I
I
.
Change Early.
Always change gear early on a bill. Never allow tbe engine to labour
in any gear and expect it to pick up speed on changing into a lower one wben the car has nearly stopped. Do not persist in attempting to drive
the car uphill in top gear wben the speed lalls below 18 m.p.h.-cbange down.
If the car bas been driven back by tbe reverse gear, wait until it is
stationary belore engaging a lorward speed. Do not engage the reverse gear when the car is travelling lorward. Serious damage to the gears will
be the result.
Keep the loot 011the clutch pedal
except in heavy trallic. Even then
do not allow tbe weight 01the loot to
be taken by tbe pedal. Tbe slipping
01the clutcb caused by tbis practice beats and wears it badly.
When descending a long bill, or before commencing a steep descent, engage one 01 the lower gears, and
do not accelerate.
The Gear Positi...,.
12
\
~
The engine will tb~n belp to retard the speed 01 tbe car. When
using the brake, keep tbe clutcb in, disengaging it at the last moment il
.topping tbe car. Skidding.
Skidding is sometimes due to sudden braking on a greasy or loose
surlace and unduly slack tyres contribute to it. If the rear wheels skid, release the brakes and turn the Iront wbeels towards the direction 01
the skid.
Synchromesh Gears.
Tbe gearbox bas lour lorward speeds and a reverse and the second
third and top gears have synchromesh engagement, which ensures silent
positive cbanges.
Cear cbanging may be sligbtly still in a new car until tbe moving parts bave eased in use. Cbanging sbould not be done burriedly and no attempt sbould be made to lorce tbe gear lever il engagement is not made at tbe lirst attempt. Sbould
dilliculty be experienced in en- gaging a gear wben tbe car is .tanding, release tbe clutcb lor a moment and tben try again.
Tbe syncbromesb mecbanism
is governed by a series 01 spring fQtt:',:
loaded balls as illustrated. Tbe internal cone on tbe inner member
makes contact witb tbe gear mne to syncbronise tbe speeds 01
botb members belore tbe dog member, overcoming tbe resist- ance 01 tbe ball A. moves on to
give positive gear engagement.
What Not to Do.
I
Second Speed Synchroni,ing Mecl.anism
A. Spring Ball Re,iotance.
Whatever you do, please do not make tbe lollowing mistakes :-
Do not lorget tbe ignition switcb wben starting up.
Do not make a last run witb tbe radiator mull closed.
Do not be cruel to tbe starter il tbe engine will not lire.
Do not toucb tbe starter switcb wbile a gear is engaged. Do not leave tbe car in gear and witb tbe bandbrake 011. Do not coast witb a gear engaged and tbe clutcb beld out. Do not lill tbe radiator witb cold water wben tbe engine is bot.
Do not leave tbe ignition switcbed on wben tbe car is not running. On no account run tbe engine in a closed garage. Tbe exbaust gasses
are bigbly toxic and a very small amount in a restricted atmospbere will produce grave, il not latal results.

REGULAR ATTENTIONS
Monthly Attentions.
O
N this and the opposite page is a handy summary of all theattentions descrihed in this handbook. The attentions under the daily,
weekly, and monthly headings are based on the assumption that the
maximum mileage per week does not exceed 500.
Under more strenuous conditions, for instance, very dusty or very
muddy roads, long distances at high speeds or with heavy loads, It wIll be
advisable to attend to the lubrication of chassis parts more frequently.
After the first few days" use tighten all nuts particularly those on the engirle cylinder head. These may loosen a little because of the heat generated, but if they receive this attention both they and the head will
remain !lecure against water leaks or loss of compression.
Waming.-After the car has been washed, or driven through water. the hrake linings may be wet. Apply the brakes a number of times for some distance in order to dry them. Wet brakes are dangerous.'
Daily Attentions.
I.
I. Examine the oil level in the
gearbox. It should be level with the filler plug. Capacity,
It pints.
Change at first 1000 and then every 6,000 miles.
2. Charge the back axle case with special lubricant, using the adapter on the grease gun. Capacity f pint. .
Change at first 1000 and then every 6000miles.
3. Grease all the hubs, as des- The Gearbox Oil Filler. scribed later.
4. Charge the steering box with special lubricant,
5. Oil handbrake gear, pedal gear and joints, engine control joints, and top of steering column.
6. Examine the battery and see that the connections are tight. (More frequently in hot weather).
7. Give a charge of the special grease to the nipple on the fan spindle.
8, Give a few drops of oil to the distributor spindle bearing.
9. Grease the front end ofthe torque tube (behind the front seats).
10. Grease the splined end of the propeller shaft (behind the gear box) Turn the shaft to expose the nipple.
11. Grease rear brake balance lever,
Examine water level in radi- . ator and fill up to within one inch of the top.
2. Examine oil level in the crank- case and add more oil if necessary. The dip rod indi- cates the level of the oil.
Change the oil first at 500 miles, then every 2,000 to 3,000 miles (3,200 to 4,800 km), when the oil reservoir gauze should be cleaned. The sump capacity is half a gallon,
3. Fill up' the petrol tank if necessary. Care should be exer- cised not to overfill the tank, which will contain five gallons.
Weekly Attentions,
I. With the grease gun charge-
Front spring shackle pins (4). Front wheel swivel pins (2).
Steering cross tube (2). Steering side tube joints (2). Rear spring pins (2).
2. Oil the following- Clutch release ring.
Foot brake pedal shaft (below steering box),
Brake cross shaft bearings (use a brush).
3, Examine both sets of brakes, and adjust if necessary.
4. Test the tyres for correct pressure and examine them for cuts, flints
and nails.
Occasional Attentions.
Clean the sparking plugs and check the settings. Examine all bolts and nuts, such as road spring dips, cylinder head
nuts, wheel nuts, these three especially when the car is new.
Examine other parts, such as steering connections, the radius rod JUlchoragebelow the gearbox, and the torque tube socket, neglect of which might be followed by an expensive repair and inability to use the car for .a lengthy period.
Occasionally dean the pump and carburetter petrol filters and float
-chamber strainers, and ever 2,000 to 3,000 miles the oil reservoir gauze
(when the engine oil is changed). Also ensure that the oil jets in the
-crankcase are dean. Flush the radiator with plenty of dean water until it runs through dear.
Clean the ignition distributor, and the contact breaker points (adjust the
latter), the dynamo and starter commutators. Clean the shock absorbers. .adjust the tappets, and the fan belt, decarbonize the engine and grind-in the valves. Check the alignment of the front wheels.

WHEELS AND TYRES.
How to use the Jack; Correct Inflation
Pressures
W
HENit becomes necessary t6 change a wheel hecause of a puncture
or for any other cause. the firstthing to do is to pull the handbrake "hard on." The spare wheel must be lifted from the rear of the car.
Before it is used test the air pressure and if it is not up to the correct
figure. use the pump to rectify it. The proper pressures are tabulated on the next page.
It is important~ have the car on
level ground. With the wheel brace the three nuts of the wheel to be removed should be slightly slackened.
but only enough for them to unscrew freely later. The wheel is tb'en
jacked up.
If it is a rear wheel. the jack
should be put in from the'side, be- tween the mudwing and the forward
edge of the.tyre, and should be placed under the rear spring between the two
clips which embrace the spring leaves.
If a froni wheel is to be attended
to, first slacken the nuts by means of the wheelbrace. Place the jack under
the front axle neaf but not under the
big nut at the end.
The operating bar (which is
stored under the rear seat cushion) fits into the jack by means of a square tube and 15secured in that position by a spring loaded ball.
The head of this bar which
engages with the jack must be
pushed well home so that a spring loaded ball may engage with a slot,
which will prevent the head of the bar slipping out while the jack is in
use.
The jack should be adjusted as nearly as possible to the required height by turning the head round by
hand before using the handle to lift the car.

hub remove the three nuts by

means of the brace; on some models, including vans. it is not necessary to remove them entirely. Pull the wheel
outwards about tin. and turn it a little to the left so that the large hole will pass over the nut. The wheel can now be pulled off the hub.
When replacing these slotted
hubs, make sure that the large holes in the wheel centre are properly fitted over their pegs, and tighten the wheel
nuts, each only a few turns at a time, until they are quite tight and secure.
Should difficulty b" experienced upon the first occasion of removing the wheel from the hub. the wheel nuts may be screwed right off. Before
replacing, wipe the outside of the brake drum and inside of the hub with an oily rag as this will ease removal on future occasions.

Care of The Tyres.
The key to economical and efficient tyre service is to maintain the
correct pressures and test your tyres at least weekly. Any loss of air
pressure can be made up with very little effort.
A gauge applied to the valve must be used, for it is seldom possible
to detect under-inflation from the tyres' appearance.
Minimum presssures to which tyres should be inflated are :-
I
I
A tyre that loses more than three to four Ibs. per sq. inch in a week
should be regarded as "suspect." First, make sure that a new valve "inside" is not required. If the tube is punctured make sure before refitting that the puncturing object is not still embedded in the cover.
It is important that both front tyres be kept at same pressure. If
because of wear or other causes. the steering develops a tendency to wander
or show signs of wobble, the front tyre pressure may temporarily be varied.

Fitting Hints.
When refitting a tyre attention is called to the following points.
To avoid trapping the tube between the edge of the cover and the
rim, always inflate the tube very slightly before placing it in the cover.
During the final inflation see that the edges of the cover are sea ted
evenly round the edge of the rim. Check this by the moulded line on the cover. which should be about a quarter of an inch from the rim all
the way round.
Covers are marked with a red spot near the wire edge. This indicates
the lightest part, which should be fitted immediately over the valve.

outer side of the tyre tread wean

the effect of such wear, turn the tyres, say every three or four tousand miles, so that the more worn sides are next to the car.
At the same time, exchange the near and offside tyres so that the unequal weight distribution and consequent wear caused by road
camber are shared.
If the front tyres begin to wear
rapidly, have the tracking of the front
wheels checked immediately and, if necessary, adjusted.

THE PETROL PUMP.
How Fuel is supplied from the Tank to
the Carburetter
,
P
ETROL is drawn from the tank at the rear'by means 01 an A.C.
petrol pump which advances the Inel in the correct quantity demanded .
by the carburetter, no more and no less.
Service on the petrol pump is available at all Austin Dealers and at all A.C. service stations, which are prepared with parts and lixtures lor repairing and adjusting all pumps il any trouble is experienced with the Inel supply.
Make sure that any dilliculty is not due to causes apart Irom the pump belore attempting to do anything to the pump.
11there appears to be lack ollnel at the carburetter. lirst ascertain if there is any Inel in the tank, and il not. replenish. Make sure that the pipe and connections between the tank and the pump, and between ,the pump and the carhuretter, are not leaking. In case 01 broken or damaged
piping replacement should be made.
lt may be that the litter cover of the petrol pump is loose. 11this is
the case, tighten the main nut at the top, lirst ascertaining that the cork gasket lies lIat in its seat and is not broken or unduly compressed. A gasket compressed hard may need to be replaced.
Clean the Filter.
Occasionally remove the cover and dean the lilter screen underneath it. Also remove any sediment Irom the chamher below the lilt er by taking out the drain plug (F.) Make sure that the libre washer is under the head 01th. plug belore replacing.
When re-assembling, take care that the cork gasket is replaced correctly, under the cover, and that the libre washer is under the head 01the screw.
11petrol appears to be leaking at the edge 01 the diaphragm tighten the cover screws alternately and securely, but do not attempt to dismantle the pump body.
Sometimes there appears to be a leakage 01 luel at the diaphragm joint. The leakage may actually exist at one 01 the pipe littings, causi~g the Inel to run down the pump on to the diaphragm lIange.
In hot weather when petrol is likely to evaporate, or when dilliculty might be expected on cold mornings, it is advisable to lilI the carburetter by operating the hand priming lever on the pump before attempting to start the engine. lt will be appreciated that il the engine comes to rest when the rocker arm is on the high point 01the eccentric the priming lever will be inoperative. In the event 01 this the engine should be turned over one revolution by hand.
The pumping action 01 the diaphragm can be distinctly lelt until
the carburetter bowl is lull.
Alter removal 01the upper casting on any type 01A.C. Inel pump it is
important that the cover should only be replaced while the pump pull rod

and opening (B) into the carburetter.
When the carburetter bowl is lilled the lloat in the lloat chamber will shut 011the inlet needle valve, thus creating a pressure in pump chamber (G). This pressure will hold diaphragm (H) downward against the spring pressure U)andit willremaininthis positionuntil the carburetterrequires
lurther Inel and the needle valve opens.
The rocker arm (Q) is in two pieces, the outer one operating the inner by making contact at (R) and the movement 01the eccentric (0) is absorbed by the "break" when Inel is not required.
Spring (N) is merely lor the purpose 01keeping the rocker arm (Q)
in constant contact with the eccentric (0) to eliminate noise.
