THE information contained in: this Operation
Manual has been confined to the essentials
necessary for the proper running and driving. of
the car. Nevertheless, the owner will find all the
information required to maintain the car in first-
class condition and to enable him to give it those
.all-important items of attention which go so far to-
ensure trouble-free and satisfactory service.
Every car leaving the Works is capable of
giving absolute satisfaction if attention is given
to the essential maintenance operations detailed
in this book. Remember that Austin Distributors/
Dealers are better equipped to provide routine
and repair service than the owner-driver; therefore, '
if you encounter trouble consult the Distributor
or Dealer or the Service Department of Austin
Motors Limited — they are at your- service.
An exchange scheme for many major items and
assemblies is run by B.M.C. Service Limited; ask
your Distributor or Dealer for details.
For those requiring information of a more detailed
and technical nature than is contained in the
Operation Manual, a Workshop Manual is available
at a reasonable price from your Distributor or
Dealer.

INSTRUMENTS
Speedometer: Indicates the vehicle speed and total mileage.
The trip figures at the top of the speedometer face can be reset
to zero by pushing up the knob at the bottom of the speedometer
and tmning it to the right.
Tachometer: This instrument indicates the revolutions per
minute of the engine and thus assists the driver in determining
the most effective engine speed range for maximum performance
in any gear.
Oil Pressure Gauge: Indicates the engine oil pressure. The
pressure may rise to over 60 lb. per sq. in. (4.2 kg./cmP) when the
engine is started up from cold, but after the oil has circulated and
becomewarm the pressureshould drop to approximately 60 lb.
per sq. in. (4.2 kg./cm.') with a proportionately lower idling
pressure. Should the gauge fail to register any pressure at all,
stop the engine immediately and investigate the cause.
Ignition Warning Light: Should glow red when ignition is
switched on and fade out when the generator starts charging the
battery. Failure to do so should be investigated immediately.
Main Beam Warning Light: A red glow appears when the head-,
lights are switched on, with the two beams straight ahead. The
light goes out when the headlights are dipped.
Fuel Gauge: The fuel gauge indicates the contents of the tank
when the ignition switch is 'On'.
Always ascertain that the ignition is switched off before
replenishing the fuel tank.
Water Temperature Gauge: This records the temperature of
the cooling water circulating in the cylinder block and radiator.

highly stressed. Beyond all doubt the owner or operator will
find that careful, considerate treatment during the vital running-in
period will be fully compensated by the resulting dependability
and efficiency that will be obtained throughout its life.
T HE importance of running-in the new vehicle canfiot be too
Fuel Pump Priming Lever
'A' is the priming lever of
the fuel pump located on
the left side of the cylinder
block.
RUNNING-IN
The following-speedsshould not be exceeded in the gears for the
first 500 miles (800 kilometres):
1st 2nd 3rd top
715 25 40 m.p.h.
10 24 40 , 64 k.p.li.
It is most import'ant to remember that at no time during the running-
in period must the engine be overloaded, as in attempting to ascend
hills in top gear at low vehicle speed. The load should be eased by
changing down to a lower gear.
Fierce acceleration must also be avoided, and remember that the
engine should never be raced in neutral.
On completion of the first 500 miles (800 km.) the running-in speed
may be progressively increased, but full power should not be used
until at least 1,500miles (2,400 km.)havebeencovered,andeventhen
only for short periods at a time. During this mileage a slight falling-
oft in engine power may develop, in which case it is beneficial to
lightly grind-in the valves and re-set the valve clearances. No engine
or complete vehicle can be considered fully run-in until it achieves
2-3,000 miles (4-5,000 km.).
The use of upper cylinder lubricant is recommended at all times,
but most particularly during the running-in period. See page 33
for recommended brands.
STARTING
the water level in the radiator. Ensure that the gear lever is in
- neutral and the handbrake is applied. If the engine is cold pull out
the choke control.
-Switch on the ignition, ensure that the ignition warning light glows
and that the fuel gauge registers, then pull the starter control firmly.
Release it if the engine fails to start within five or six seconds, wait
for the engine to stop rotating and then pull the starter again.
Should the engine not start after a reasonable number of attempts,
check up on possible causes. Do not persist in operating the starter,
as a great strain is imposed on the battery by so doing.
As soon as the engine starts, release the starter control and warm
up the engineat a fairly fast idling speed. Should the oil gauge fail
to register any pressure or if the pressure isvery low, stop the engine
8 EFORE starting the engine check the oil level in the sump and
immediately and investigate the cause. Failure to do so may result in
serious damage to the engine. Also check that the ignition warning
light goes out when the engine is running above idling speed, as this
indicates that the dynamo is charging the battery.
A thermostat is incorporated in the cooling system to assist the
engine in warming up from cold, but do not, under any circumstances,
race the engine in an attempt to speed up the process.
Push in the choke control completely as soon as the engirie will
run evenly without its use.
When the vehicle has been out of action for several days the fuel in
the carburetter may have evaporated. In these circumstances, before
attempting to start the engine, refill the carburetter by operating the
priming lever on the fuel pump, this being located low down on the
left side of the engine.
DRIVING
pedal and moving the gear lever into the appropriate position.
Should the gear not readily engage, momentarily release the clutch
pedal, after which, with the clutch again depressed, it should be
possible to engage the gear. Gradually release the clutch pedal, at
the same time gently depressing the accelerator and releasing the
handbrake. The vehicle will move forward, gathering speed in
accordance with the amount the accelerator is depressed.
Second gear is engaged by depressing the clutch pedal, moving the
gear lever out of first into the next higher gear and then releasing
the clutch pedal. Ease up the accelerator whilst changing to a higher
gear, and gradually depress the accelerator when the higher gear is
engaged.
S TART only in first gear, which is engaged by depressing the clutch
16 17

AUSTIN-HKALEY SPRITE DRIVING INSTRUCTIONS
Third'and top gears are engaged by employing the sameprocedure
as that given for engaging second.
Changing down is an exact reversal of the method outlined for
changing up, except that the accelerator must be kept depressed
whilst the gear is being changed, in order to speed up the engine in
accordance with the lower gear.
Do not change gear rapidly or forcibly. Always move the lever
with a smooth deliberate action that will allow the synchromesh
mechanism to operate properly.
To stop the vehicle, release the accelerator, apply the footbrake
and depress the clutch pedal before the vehicle comes to a standstill.
After applying the handbrake and moving the gear lever into neutral,
release the clutch and footbrake.
%hen in reverse, which must only be engaged when the vehicle is
stationary, remember that the gearing is lower than first gear;
Consequently release the clutch slowly until the vehicle just begins to
move, and then gently depress the accelerator to give the speed
desired.
Do not slip the clutch instead of using the handbrake when tem-
porarily halted on an ascent and do not allow the weight of the foot
to be taken by the clutch pedal when it is not being used, as either
practice will result in excessive clutch wear.
Before descending a steep hill it is advisable to engage an inter-
mediate or low gear. The engine will then provide a useful braking
action.
DRIVING HINTS .
Never operate the starter control when the vehicle is in gear.
Remember to switch on the ignition before attempting to start the
engine.
Do not persist in pulling the starter control if the engine will not
fire.
Release the choke control as soon as the engine will run evenly
without its use.
Do not leave the ignition switched on when the engine is not
running.
Never leave the vehicle in gear with the handbrake unapplied.
Do not engage reverse gear when the vehicle is moving forwards
or forward gear when the vehicle is moving backwards. -,Serious
damage may result.
Avoid slipping the clutch in traffic or on an ascent.
Never coast the vehicle with a gear engaged and the clutch pedal
depressed.
A FTER the vehicle has been washed or driven through water the
results.
SKIDDING
Skidding is usually due to sudden acceleration, braking or change
of direction on an icy, greasy or loose road surface. If the rear
wheels skid, release the accelerator or brake pedal (as the case may be)
and turn the steering wheel towards the direction of the skid to regain
wheel grip on the road.
WET BRAKES
brake linings may become wet. To dry them, apply the brakes
several times with the vehicle moving slowly. Emergency braking
with wet brakes is extremely dangerous and is to be avoided at all
Do not race the engine in neutral at any time.
Never run the vehicle with the radiator completely blanked otf.
Avoid running the engine at high speeds for the first 500 miles
(800 km.).
Never fill the radiator with cold water when the engine is hot.
Do not, under any circumstances, run the engine in a closed garage
or similar restricted atmosphere. The exhaust fumes are highly
poisonous and if inhaled will quickly produce grave, if not fatal,
costs.

Engine Oil Filter: At the same time as the engine oil is changed,
drain the full-flow filter and renew the filter element, not for-
getting to top-up the filter container with new oil before refitting
it to the head casting on the engine crankcase (see page 38).
N.B.: On no account must this attention be neglected as it is
essential that the oil filter does not become clogged with dirt.

Water Pump:Remove the oiling plug on the water pump casing
and add a small quantity of SAE 140 oil. The oiling of the
pump must be doneverysparingly otherwiseoil will flow past the
bearings on to the face of the carbon sealing ring and impair
its efficiency.
Front Road Whee/ Hubs: Remove the wheel, lever out the
hub cap with a screw-driver, and recharge with grease. It is
important that the hubs are not overgreased, due to the fact that
any surplus may find itsways to the brake linings, thusreducing
their efficiency.
Air Cleaners: The air cleaners should be removed, cleaned and
re-oiled. Swill each cleaner in petrol, drain, immerse in engine
oil and again drain before refitting.

essential to the efficient operation of the vehicle, and is additional
to or more detailed than that given in 'Regular Attentions'.
ENGINE
to the engine, which may have to operate at sustained high
temperatures and speeds,and it is therefore essential that only
oils of the highest quality and correct grade are used. Inferior
oils will cause excessivewear in an unduly short time.
The colour or appearance of an oil at atmospheric tem-
peratures gives no indication as to its efficiency under operating
conditions and owners are advised to use the officially recom-
mended lubricants as listed on page 33. It is appreciated that
in some areas these oils are not available, in which case, only
good quality oils conforming with the S.A E. numbers listed
The letters S.A.E. followed by a number constitute a classifi-
cation of the lubricant in terms of viscosity or fluidity.
For instance, a low S.A.E. number indicates that the oil is of
low viscosity, which means that it flows more readily than oil
with a high viscosity rating.
lt will be appreciated, therefore, that oil with a low S.A.E.
number is essential if easy starting is to be obtained in cold
weather, whereas in hot weather a high viscosity oil is desirable
in order to keep oil consumption within normal limits.
The use of upper cylinder lubricant is recommended at all
times, but most particularly during the running-in period. See
page 33 for recommended brands.
Even the best oils in the engine become contaminated during
use, with unburnt fuel, carbon, metallic particles, and moisture,
and it is therefore most important that the oil is changed at the
recommended mileages.
Multigrade Motor Oils: In addition to the recommended
lubricants listed on page 33, we approve the use of multigrade
oils, as producedby the oil companiesshown on our list, for all
climatic temperatures unless the engine is old and in poor
mechanical condition. Some are more expensive than the recom-
mended motor oils because of their special properties and
greater fluidity at low temperatures.
Oil Level: The oil should never be allowed to fall more than
—',in. (12.7mm.) from the 'FULL' mark on the dipstick. It
is advisable to wipe the dipstick before taking the reading, which
must only be taken when the engine is stationary and the vehicle
on level ground if a true result is to be obtained.
Lubrication: Correct lubrication is of the utmost importance

reaches the bearings at. a reduced pressure of approximately
35 lbs. per sq. in (2.46 kg./cm.'). Therefore, to ensure only
filtered oil is supplied to the bearings it is essential to renew the
filter element at 6,000 miles (10,000 km.) or when the oil pressure
gauge indicates the change is necessary by a fall in pressure.
Rertewing Filter Element: First drain the filter by removing the
centre fixing bolt from the base of the container. With the bolt
removed it will be necessary to support the container by hand
until all the oil has drained away. Withdraw the container com-
plete with the element. Slide out the filter element and, using a
non-fluffy cloth, thoroughly clean out the container internally and
externally. Insert a new element in the container, and holding
the centre fixing bolt in position against the bottom of the
container, fill with new oil. Now, still holding the bolt in this
position, locate it in the filter head casting and tighten just
sufficiently to make an oil tight joint.
This is the only attention likely to be required. The filter con-
tainer should not be removed or drained, once a new element has
been fitted, until element renewal is required.
Oil Pressure:The oil pressure gaugeindicates whetherthe oiling
system is working properly. It should be looked at occasionally
while the engine is running.
The engine oil pressure may rise to over 60 lbs. per sq. in. (4.2
kg./cm.') when the engineis first started up in cold weather, but
after theoil hascirculated and becomewarmthepressurewill drop
to 60 lbs. per sq. in. (4.2 kg./cm.') with a proportionately lower
idlingpressure.
Never run the engine if the gaugefails to register a pressure or
if the prbssure is very low. Switch off and investigate the causeof
the failure as otherwise serious damage might result.
Full Flow Filter: Before reaching the engine bearings the oil is
passed through a full flow filter at a controlled pressure of
approximately 60 lbs. per sq. in. (4.2 kg./cm.'). Some pressure
is lost in passing the oil through the filter element and this pressure
loss will become more pronounced as the element becomes
coated by foreign matter removed from the oil.
A balance valve is provided in the filter unit to guard against
the possibility of the filter becoming completely choked and
thereby preventing the oil from reaching the bearings. This
balance valve is set to open when there is a pressure difference
between the oil on the inside and the oil on the outside of the
filter element of 15 lbs. per sq. in. (1.06 kg./cm.'). When the
valve is open, un-filtered oil by-passes the filter element and
FUEL SYSTEM
FUEL is stored in a rear mounted tank of 6 gallons (27 litres)
capacity. An A.C. mechanical'Y' type fuel pump, operated by
the enginecamshaft, draws fuel from the tank and delivers it under
pressure to two S.U. type H.l carburetters. Twin 'pancake'
type air cleaners filter the air to the carburetter intakes.
Fuel Pump: This is bolted on the left-hand forward side of the
engine crankcase and has a suction pipe from the tank and an
outlet pipe to the carburetters. A priming lever is fitted to
enable the carburetters to be primed by hand, should the fioat
chambers become dry due to evaporation. If petrol appears to
be leaking from the edge of the pump diaphragm, tighten the
covers screws alternately. Sometimes such leakage may actually '
come from one of the pipe unions causing the fuel to run down
to the pump and collect around the diaphragm flange.
The pump filter should be examined and cleaned if necessary.
Access to it is gained by removing the dome cover, after un-
screwing the retaining screw, when the filter gauze itself may be
lifted off its seating. Clean out the sediment chamber and clean
the filter gauzeinan air jet or petrol. The gasketunder the filter
cover should be replaced if broken or if it has hardened.
When refitting the cover, make certain that the fibre washer is
replaced under the head of the screw. Tighten the filter cover
retaining screw just sufficiently to make a fuel tight joint.
