The

AUSTIN SEVEN

HE Austin Seven is acknowledged to be the best small car in the world.

It is designed for, and will carry in comfort, three adults or

two adults and three small children: or again it accommodates amply, two adults and their luggage up to a total weight of 30.32

stones,

There are four models made, the Tourer, the Metal

Saloon, the Fabric Saloon, and the Coup!" ,The Touier, with its easily operated hood, and side curtains that open with the doors, provides complete protection in even the most inclement weather. The closed models are alike in general lines and equipment. A particularly good feature is the wide door, carrying two glass panels, onellifting and one sliding. The large single panel windscreen, that can be opened wide, is another advantage. The Coupe model has the same features, bnt is designed to seat two persons, space being provided for luggage.

In all models the front passenge~ seat tilts forward and allows ready access to the rear seats or luggage space. All models have Triplex glass front screens.

It has a 4-cylindcr, water-cooled engine, three-speed gear. box, and bevel drive through the differential. Lubrication is by pump, and cooling is on the thermo-syphon system and by

fan.

The complete equipment includes electric starting and lighting, air strangler, electric horn, speedometer, automatic windscreen wiper, license holder, shock absorbers, spare wheel and tyre and blank number plates.

"'"

~~\

Brakes are fitted to all four wheels which carry 26 X3! in.

Dunlop balloon reinforced cord tyres.

The Austin Seven is particularly suitable for the woman driver. It requires little physical effort to drive and control, and for that reason its use enables her to do shopping calls without fatigue, visit her friends, attend social and other functions, or make excursions or trips in any direction in any weather. For

the same reasons business men find it an excellent vehicle, and commercial travellers and others whose occupation compels frequent calls over an extended area, have in the little car an embodiment of all they require. 'Calls can be made in places

where trains, trams and 'buses are infrequent.

In large establishments where the use of a big car for short

runs with messages, on shopping, emergency calls at short notice, as ir case of sudden illness, would .be found costly and

inconvenient, the" Seven" has proved to be a splendid "tender," saving time and money.

As 45 to 50 miles per gallon is the averag'e petrol consump' tion, the cost of transit is below the cost of fares on any public conveyance, and in this particular the Austin Seven

has no rival. '

Its speed, economy, reliability and road.holding qualities

have been admitted beyond dispute.

Thousands of motorists have had their first experiences on a " Seven," thousands more will follow them.

It has successfully passed through years of severe use and

trial. and emerged a really successful and popular favourite.

The

NEW

CAR

N, taking possession of a new car it is advisable to give

It a general exammahon to see that all is complete and

in order. .

Make sure that the tool-kit is complete, check ~ver

according to the list given on page 50. .

If you are not already familiar with Austin cars, we strongly

recommend that this handbook be carefully studied.

Before running see that the car is supplied with fuel and water and that the engine and gearbox have the necessary quantities of oil. The battery should contain the required amount of acid. For quantities of oil and acid see sections " Lubrication" and" Electrical Equipment."

Should the car be delivered by road it will be ready for running but if it has been transported by rail or overseas, the engine may have become stiff through the gumming of the oil on the pistons. They may be freed by the injection of a little petrol into the cylinders, through the compression plugs, and then turning the engine a few revolutions with the starting handle.

When a car is crated for dispatch overseas, water, fuel, and

oil are removed and the battery lelt empty and nncharged.

Starting the Engine

Make sure that the change speed lever is in neutral position

and the hand brake on.

Turn on petrol tap at the bottom of the petrol tank (this

will be found under the bonnet).

Set the engine control levers at the top of the steering wheel

-Throttle-open about t iJ1. Ignition-almost fully advanced.

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), then

switch on, turning the left-hand switch to "Summer t Charge" or " Winter

Full c." Pull out the wire on the

instrument board to close the car- I

buretter air inlet, and again give the I, \

crankshaft a few sharp turns by A C B means of the starting handle, making sure to pull the handle upwards to commence with, or firmly press the starter switch.

Be suretoreleasetheair shuttErwire after theenginehasstarted. Do

not try to start the engi,\: when cold by the electric starter, nor allow the engine to race when first starting up, as time must

be allowed for the oil to circulate and lubricate various bearings.

Never lean 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.

Dift'iculty in Starting

Difficulty in starting may be 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 pilot jet, and it may not be necessary to flood the carburetter; in any case it should only be flooded slightly. If petrol is passing through the carburetter the suction can generally be heard. If the engine fails to start and there is a good deal of petrol overflowing from the carburetter it is almost certain that the mixture getting into the cylinder is too rich. Tbe throttle should then be opened half-way to reduce the suction. On firing, the engine will race away, and the throttle should be almost closed. Ifthe engine does not fire close the throttle, entirely

and try again. After a stop i;' hot weather, failure of the engine to start is more likely to be due to too rich a mixture than one too

lean, and one should stop the engine by the switch only after quite closing the throttle. Re-start the engine with the throttle closed.

If after the foregoing measures have been carried out the engine fails to start the reason will probably be due to faulty

ignition or carburation.

IGNITION: 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 of the gauge provided in the tool kit.

If the points are dirty, clean them before replacing the plug. For

fuller details on the ignition system see page 20.

CARBURATION:The slow running jet may be stopped up or a main jet choked. Blow them out with a tyre pump. For fuller details about the carburetter see page IS,

The engine should never be allowed to run at

high speeds for the fir~ 300 milt;s.

The engine should never be allowed to run at high speeds for the first 300 miles.

CONTROL OF THE CAR

Setting of Control Levers

FTER having started the engine, keep the ig

nition lever in

the advanced pos[tion; should the engine commence to

, " rumble" or run roughly, retard the lever, but advance

it,again as soon as the load on the engine is lessened. The " gas" lever should be set generally for slow running and the

speed of the car controlled by the accelerator pedal.

Changing Gear

Double declutching will be found the best method of gear

changing on the Austin Seven,,- and should be adopted

straight away. Also when changing up the foot should' be

taken off the accelerator pedal, and when changing to a lower gear it should be held down. The car shOllld be well accelerated on each speed when changing up, and a deliberate pause should be made with the gear lever in neutral position and with the clutch in whether changing up or down. The catch below the knob of the gear lever must be raised to allow the reverse gear to be engaged.

Always change gear early on a hill; never allow the engine

to labour in any gear and expect it to pick up speed on changing

into a lower one when the car has nearly stopped.

Keep the foot off the clutch pedal except in heavy traffic. Even then, do not allow the weight of the foot to be taken by the pedal. The slipping of the clutch caused by this practice heats and wears it badly.

When descending a long hill, supplement the action of the foot-brake at intervals by

the use of the hand-brake for brief periods. It is often

advisable to engage one of the lower gears before commencing a steep descent, with throttle closed. When using the brake,

keep the clutch in, disengaging it at the last moment if stopping the car.

The driving seat of the Austin Seven is adjustable for

position and this convenience should be taken advantage of so

as to obtain the greatest comfort, '

"""

CHANGING A WHEEL

The Spare Wheel

HEN it becomes necessary to change a wheel because

. of a puncture or for any other cause, the spare wheel

must be lifted from its bracket at the rear of the car,

to which it is fastened by three wheel nuts, in the same way as the wheels are attached to the hub.

It is important to have the car on level ground. With the wheel brace the three nuts (A) of the wheel to be removed should be slightly slackened, but only enough for them to unscrew freely later. The wheel is then jacked up. If it is a rear wheel, the jack should be placed under the rear spring anchor- age on the axle (or if the car is unavoidably on uneven ground it may be advisable to block the jack up, to increase its lift).

To detach the wheel from the hub loosen the three nuts (A),

by means of the brace; it is not necessary to remove them entirely. Now pull the wheel outwards about! in. and turn it so that the large hole will pass over the nut. For a front wheel this can be done more easily if the hand brake is on so that the hub cannot turn. With a back wheel, if the brake

cable is pulled down to put on the brake while the wheel is being detached, the movement will be similarly facilitated. The wheel can now be pulled off the hub.

When replacing 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 home.

Should diiticulty be 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 the removal

on future occasions.

PERIODICAL

ATTENTIONS

N this and the opposiie page is a handy

. . summary 01 all the attentions described 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 300.

The occasional attentions should not be neglected il the car is to continue to run efficiently. When relerring to the attentions below. see the lubrica- tion chart on page 14.

Daily Attentions

1. Examine water level in radiator' and

fill up to within 2 in. of the top. Always use'" the strainer when re-filling as

dirty water will cause the radiator film to become choked.

2. Examine oil 'level in the crankcase and add more oil if necessary. The tell-tale dipper rod indicates the level of the oil (see illustration, page 27).

3. Fill up the petrol tank if necessary. Care should be exercised not to overfill

the tank and spill the petrol over the engine.

Weekly Attentions ..

1. With the grease gun charge-

Front spring shackle pins (4). Rear spring pins (2).

Front wheel swivel pins (2). Steering cross tube (2).

2. Oil the following-

Handbrake gear. Pedal gear and joints. Engine control joints. Clutch release ring. Rear brake cam spindles (2). Steering side tube joints (2).

3. Examine both sets of brakes, and adjust if necessary.

r-"

(

4. Inject high speed grease (such as Messrs. Stern's" Diamol") into the universal joint at the rear end of the propeller shaft and yellow grease into the front eud of the torque tube.

5. Test the tyres for correct pressure and examine them for cuts (see page 49).

6. Give one turn to the cap of the lubricator

for the main distributor bearing, page 21.

Monthly Attentions

1. Examine the oil level in the gearbox

which should contain two-thirds of a pint, or measure 2-21 iu. deep.

2. Charge the back axle case with a gunful

of grease and oil mixed half and half, using the special adapter on the grease gun.

3. Fill all the hubs with grease, as described on pages 30 and 31.

4. Charge with grease the steering worm

case through the nipple.

5. Examine the battery and see that the

connections are tight. For details see page 34.

6. Give a charge of grease to the nipple

on the fan spindle.

Occasional Attentions

" ,

Examine all bolts and nuts. such as road spring clips, cylinder head nuts. wheel nuts (these three especially when the car is new). examine other parts such as steering connections.

the radius rod anchorage below the gearbox. and the torque

tube socket. neglect 01 which points might be lollowed by an expensive repair. and the inability to use the car lor a lengthy period.

Occasionally clean the petrol filler and float chamber

strainers. the radiator filler strainer. the oil filler strainer. and the oil reservoir gauze (when the engine oil can be changed); also ensure that the oil jets. .under the plugs on the crankcase. are clean. Drain the gearbox and refill with fresh oil (i pint).

Flush the radiator through. Clean the ignition dis-

tributor, and the contact breaker points (adjust the latter), the dynamo and starter commutators. Clean and lubricate

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. For details of these attentions reler to the pages that follow. IT
