CATALYTIC CONVERTER PRECAUTIONS
1. Use unleaded fuel only. This is essential to maintain the efficiency of til
emission control system. Unleaded fuel has the additional advantage that il
minimizes spark plug fouling, thereby giving improved engine performanc '.
2. Have your car maintained in accordance with the Maintenance Summary
outlined in this handbook. A correctly tuned engine minimizes exhaust
emissions and achieves the optimum performance and fuel economy.
3. Do not continue to operate your car if you detect any engine malfunction.
Misfire, or engine run-on may cause unusually high catalytic converter
temperatures. Damage to the catalytic converter 'may occur if any such
engine malfunctions are not rectified immediately.
4. DO
NOT LEAVE YOUR CAR UNATTENDED WITH THE ENG INE
RUNNING AT ANY TIME as an unobserved rise in engine temperature
may cause damage to the engine and catalytic converter.
5. The use of a catalytic converter increases exhaust system temperatures. Do
not operate or park your car in areas where combustible materials such as dry
grass or leaves may come in contact with the exhaust system. The exhaust
system could ignite such materials under certain weather conditions.
6. Do not run the engine with a spark plug lead disconnected or a spark pili
removed or use any device that requires an insert into a spark plug hole in
order to generate air pressure (e.g. tyre pump, paint spray attachment, etc.)
as this could also result in catalytic converter damage.
7. Do not push or tow your car to start it. Use jumper cables. Under certaiI
conditions, pushing 'or towing could damage the catalytic converter.
S. The catalytic converter contains a ceramic material. Avoid heavy impact.

you should leave the vehicle where it is
and call for assistance. Even if you are
satisfied
that it is safe to proceed, the car should only be driven in cases of real
emergency,extreme care should be taken and heavy braking avoided. In deciding
whether it is safe to proceed you should cons ider whether you will be infringing
the law.
Braking system The hydraulic brake system has two independent circuits. If hydraulic pressure
fails in one circuit, the remaining circuit will provide an emergency brake con-
dition on the
other two wheels and allow the car to be brought to rest by brake
pedal appl ication. This would be accompanied by the warning lamp (5) glowing

STARTING AND RUNNING INSTRUCTIONS
The following instructions are a guide for starting, running and loading the car,
and include notes on the use of the controls and the indications of the instruments..
Running in The treatment given to a new car will have an important bearing on its subsequent
life,
and engine speeds during this early period must be limited. The following
instructions should be strictly adhered to.
During the first 500 miles (800 km):
DO NOT exceed 45 m.p.h. (72 km/h).
DO NOT operate at full throttle in any gear.
DO NOT allow the engine to labour in any gear.
Exhaust 1. The catalytic converter contains ceramic material. Avoid heavy impacts on
catalytic the converter casing.
converter
2. Use unleaded fuel only (91 octane). The use of leaded fuel will seriously impair
the efficiency of the emission control system.
3. The reaction in the catalytic converter increases exhaust system temperatures.
Care
must be taken to avoid exhaust system contact with easily combustible
materials such as dry grass.
4. If the engine misfires, the cause mu tb immediately rectified to prevent
catalytic converter damage.
5. The use
of any device which require an in rt into a spark plug hole in order
to generate an air pressure, i.e. tyre pump or paint spray attachment, could
also result in catalytic converter
dam age. .
Choice of fuel The engine has been designed to operate only on unleaded fuel. It is essential that
unleaded fuel is used otherwise serious damage can be caused in the catalytic
converter.
Filling with The filler neck of the fuel tank is designed to accept fuel dispenser nozzles of the
fuel type specified only for unleaded fuel. The dispenser nozzle must be inserted into
the filler neck sufficiently to open the
trap door for fuel to flow into the fuel tank.

Starting and Running Instructions
Starting Sit in the car, then wear and fasten the seat belts; this applies to both driver and
passenger.
Switch on the ignition and check:
That the ignition warning light glows.
That the fuel gauge registers.
Depress the throttle pedal fully and release.
Operate the starter. Do not depress the throttle pedal while the starter is operated.
As soon as the engine is started check:
That the oil pressure gauge registers.
The ignition warning light has gone out.
Quickly depress and release the throttle pedal to set the automatic choke to its
correct position.
NOTE: For cars operating in sub-zero temperatures, slowly depress the throttle
pedal until 2,500 revfmin is attained; maintain this speed until the engine reaches
normal operating temperature.
Ignition The lamp should glow when the ignition is switched on, and go out and stay out
warning lamp at all times while the engine is running above normal idling speed. Failure to do
so indicates a fault in the battery charging system. Check
that the fan belt is
correctly tensioned before consulting your authorized Austin MG Dealer.
Gear change Under normal driving conditions, it is recommended that to maintain the most
speeds favourable exhaust emissions and fuel economy, the gears are selected at the
following speeds:
1st to 2nd ..
2nd to 3rd . .
3rd to 4th . .
Tachometer For normal road work, and to obtain the most satisfactory service from you r
engine, select the appropriate gear to maintain engine speeds of between 2,000
and 4,500 revImin.
When maximum acceleration is required upward gear selections should be made
when the needle reaches the yellow sector (5,500-6,300 rev/min). Prolonged or
excessive use of the highest engine speeds will tend to shorten the life of the
engine. Allowing the engine to pull
hard at low engine speeds must be avoided
as this also has a detrimental effect on the engine.
The beginning of the red sector (6,300 rev/min) indicates the maximum safe speed
for the engine.
Never allow the needle to enter the red sector.
Wet brakes If the car has been washed, driven through water, or over wet roads for prolonged
periods full braking power may not b v ilabl . Dry the brakes by applying the
foot brake lightly several times, while th r i in motion. Keep the hand brake
applied while using high pressure wa hing uipment.
Oil pressure
warning lamp
The lamp will glow when the ignition is switched on and go out soon after the
engine is running.
Vehicle loading Due consideration must be given to the overa ll weight carried when fully loading
the car. Any loads carried on a luggage rack or downward load from a towing
hitch must also be included in the maximum loading.
Towing Should it become necessary to tow the car, use the towing eyes provided.
for recovery
The ignition/steering lock key must be at positions 'I' or 'II' and must not be
removed during the tow. For tow starting the key must be at position 'II'.
If the light continues to glow, stop the engine immediately and investigate the
cause. Start by checking the oil level.
Starter Do not operate the starter for longer than five to six seconds.
If after areasonable number of attempts the engine should fail to start, switch
off the ignition and investigate the cause. Continued use of the starter when the
Starter Do not operate the starter for longer than five to six seconds.
If after areasonable number of attempts the engine should fail to start, switch
off the ignition and investigate the cause. Continued use of the starter when the
engine will not start not only discharges the battery but may also damage the
starter.
If the starter pinion fails to engage .with the flywheel ring, or fails to disengage
when the engine starts, the starter will emit a high-pitched whine; release the
ignition key immediately. Should the starter pinion become
jammed in mesh with
the flywheel ring, turn the squared end of the armature spindle with a spanner.
Temperature Normal operating temperature is reached when the pointer is in the 'N' sector.
gauge
Overheating may cause serious damage. Investigate any upward change in the
temperature gauge reading immediately. Check coolant level
and fan belt tension.
Towing The towing weight of 1,3441b (610 kg) is the maximum that is permissible.
When
using bottom gear a gradient of up to 1 in 8 can be ascended while towing a
weight not exceeding this figure. It may be necessary to adjust the maximum
towing weight to comply with local conditions and regulations. The recommended
downward load of a trailer or caravan on the towing hitch is 75 lb (34 kg), but
this may be reduced or exceeded at the discretion of the driver. Any load carried
on the luggage rack or downward load from a towing hitch must also be included

ENERGY CONSERVATION
It is essential that owners wishing to achieve the best possible degree of fuel
economy ensure, as a first priority, that their vehicle is tuned to its optimum level
of performance by regular maintenance in accordance with Leyland recom-
mendations.
Apart from regular maintenance there are a number of areas where deliberate
and conscious actions on the
part of the owner can achieve further quite marked
improvements. The following are recommended:
•After starting from cold, quickly depress and release the throttle pedal to set
the automatic choke to its correct position.
• Switch off the ignition if the vehicle is expected to be stationary for more than
half a minute.
• Avoid short stop-start journeys.
•Anticipate obstructions, junctions and sharp corners and adjust speed as
necessary. Do not generate unnecessary speed.
•Accelerate gently through the gears.
•Decelerate gently whenever possible and avoid heavy braking.
• Stay in top gear as long as possible without labouring the engine.
•Ensure tyres are correctly inflated.
•Remove any unnecessary weight.
CAUTION: Carburetter piston damper
An incorrectly fitted or lubricated carburetter piston damper can cause a marked
increase in fuel consumption. The cautionary note and instructions on carburetter
damper topping-up given on page 68 of this handbook

away from the seat.
SEAT BELTS Fig. 2
Warning The seat belt warning system functions when the ignition/starter switch is opera-
system ted.
The
'FASTEN BELTS' lamp will be switched on for eight seconds each time the
ignition /starter switch is operated. The warning buzzer will sound for eight
seconds if the ignition/starter switch is operated before the driver's seat belt is
fastened.
Testing
Care of the
belts
WARNING: This test must be carried out under safe road conditions, i.e. on a
dry, straight paved road, during a period when the road is free from traffic. With
the belts in use, drive the car at 5 m.p.h. (8 km./h.)
and brake sharply. The
automatic locking device should operate and lock the belt. It is essential that the
driver
and passenger are sitting in a normal relaxed position when making the
test. The retarding effect of the braking must not be anticipated.
If a belt fails to lock, consult y
our a uth orized Aust in/MG Dealer.
No unauthorized alterations or additions to the belts
should be made. Inspect
the webbing periodically for signs of abrasion, cuts, fraying and general wear;
pay particular attention to the fixing points
and adjusters.
~ig •.1
Fig•.1
Wearing
Always wear a belt as a complete lap and diagonal assembly and never at any time
wear it loosely, as this reduces its protection. Ensure
that the belt is lying flat
and not twisted. Always stow a seat belt that is not in use.
Never
attempt to use a seat belt for more than one person, even for small children.

Do not attempt to bleach the belt webbing or re-dye it. If the belts become soiled,
sponge with
warm water using a non-detergent soap and allow to dry naturally.
Do not use caustic soap, chemical cleaners or detergents for cleaning. Do not dry
with artificial heat or by direct exposure to the sun.
Renew a seat belt assembly that has withstood the strain of a severe impact.

HEATING AND VENTILATING
CLEANING
HEATERThe heating and ventilating system is designed to provide fresh air either heated
by the engine cooling system or at outside temperature to the car at floor level
and for demisting and defrosting to the windscreen.
Interior Carpets: Clean with a semi-stiff brush or a vacuum cleaner,preferably before
washing the outs ide of the car. Occasionally give the carpets a
thor ough cleaning
with a suitable uph olstery cleaner. Carpets must not be 'dry-cleaned'.
Air Two doors,located one at each side of the gearbox tunnel, control distribution
distribution of air between screen and car interior. To supply air to the car, open the doors;
to boost the flow of air to the screen, close the doors.
Plastic faced upholstery: Clean with diluted
uph olstery cleaner. Spot clean with
upholstery cleaner spread thinly over the surface with a brush or cloth, leave for
five minutes, then wipe over with a damp sponge or cloth.
Controls Heater (Fig. 1). A valve controlling the flow of coolant through the heater unit
is fitted on the bulkhead beside the battery. The valve is opened (1) by moving
the lever towards the battery. Moving the lever away from the battery closes (2)
the valve.
Air flow (Fig. 2). The
knob (1) operates a valve in the air intake and controls the
flow of air to the car interior.
Turn the knob anti-clockwise from the ' OFF '
position to open the valve, the valve is fully open when the
knob is turned to
the 'ON' position.
Booster. Press the lower end of the switch rocker (2) to boost the air flow.
Illumination The markings on the booster switch, the control dial and the position indicator
on the rotary c
ontr ol knob are illuminated when the panel lamps are switched on.
Body Regular care of the body finish is necessary if the new appearance of the r
exterior is to be maintained against the effects of air pollution, rain,
and mud .
Wash the bodywork frequently, using a soft sponge
and plenty of water con-
taining car shampoo. Large deposits of mud must be softened with water before
using the sponge. Smears should be removed by a second wash in clean water,
and with the sponge if necessary. When dry, clean the surface of the car with
a damp chamois-leather. In addition to the regular maintenance, special attention
is required if the car is driven in extreme condit ions such as sea spray or on
salted roads. In these conditions and with other forms of severe contamination
an add itional washing operation is necessary which should include under-
body hosing. Any damaged areas should be immediately covered with paint and
acomplete repair effected as soon as possible. Before touching-in light scratches
and abrasions with paint, thoroughly clean the surface. Use petrol/white spirit
(gasoline/hydrocarbon solvent) to remove spots of grease or tar.
Usag eBy varying the settings of the air flow control, opening or closing the air distri-
bution doors, and utilizing the booster blower, a wide range of settings
can be
obtained for heating, when the heater valve is open, or for ventilating when the
valve is shut, to suit prevailing conditions.
Bright trim Never use an abrasive on stainles , chromium, luminium, or plastic bright parts
and on no account clean them with m tal poli h. Remove spots of grease or tar
with petrol/white spirit (gasoline/hydroc rbon lvent) and wash frequently with
water containing car shampoo. Wh n th dirt ha been removedpolish with
a clean dry cloth or chamois-leather until bright. Any slight tarnish found on
stainless or plated components which have not received regular attention may be
removed with chrome cleaner. An occa ional application of light mineral oil or
grease will help to preserve the fini h, particularly during winter when salt may
be used on the roads, but these protectives must not be appl ied to plastic finishes.

COOLING SYSTEM
Expansion The expansion tank (1) and the spill tank (2) collects the coolant displaced by
tank and cap expansion when the engine is heated to normal running temperature. The
Fig. 1 displaced coolant is.returned to the radiator when the system cools. The cap (3)
on the expansion tank maintains the pressure in the cooling system to 15 lbf/in"
(1·05 kgf/cm") maximum when the engine is running. If the sytem is hot, protect
the hands against escaping steam, turn the cap anti-clockwise until the stop is
felt, wait until all pressure has escaped, then press down and 'turn further until
the cap can be lifted off.
Checking The coolant level must only be checked when the system is cold.' Remove the
expansion
tank cap to check the coolant level which must be maintained to the
half-full point of the tank.
Draining To drain the cooling system, stand the car on level ground, remove the expansion
Fig. 1 tank cap (3), and the filler plug (4) from the coolant outlet elbow. Slacken the
hose clip and disconnect the bottom hose (5) at its connection to the radiator.
Remove the drain plug (6) on the cylinder block.
Collect the coolant in a clean container if it is to be used again as cars are filled
with a 50 per cent solution of anti-freeze before they leave the factory.
There is no provision for draining the heater, expansion tank or spill tank.
FiIIing Anti-freeze must be used in the cooling system when freezing conditions are
Fig. 1encountered.
Refit the drain plug (6), re-connect the bottom hose to the radiator, and check all
other hose connections.
Fill the system with coolant through the filler orifice until the level is up to the
bottom of the threads. Refit the filler plug. Top up the expansion tank with
coolant to the half-full point and refit the cap.
Run the engine until normal operating temperature is reached. Stop the engine,
allow the system to cool, and remove the expansion tank cap. Remove the filler
plug and 'top up to the bottom of the threads and refit the filler plug. Top up
the expansion tank to the half full point and refit the cap.
Fig. 1
Frost Water expands when it freezes, and if precautions are not taken there is con-
precautions siderable risk of bursting the radiator, cylinder block, or heater. The heater unit
cannot be drained with the cooling system; it is therefore essential to use anti-
freeze in the cooling system in freezing conditions. '
When freezing conditions are likely to be encountered, have the specific gravity
of the coolant checked by your authorized Austin MG Dealer, and add anti-
freeze to give the required protection.
After the second year the system should be drained and flushed by inserting a
hose in the filling orifice and allowing water to flow through until clean. Ma
sure that the cooling system is water-tight, examine all joints and replace any
defective hose with a new one. Refill with the appropriate anti-freeze solution
and add 0·25 pint
(t U.S..pint, 0·15 litre) of neat anti-freeze to the expansion
tank.
We recommend owners to use an ethylene glycol based anti-freeze to specification
B.S. 3151/2 or S.A.E. JI034 to protect the cooling system during frosty weather
and reduce corrosion to the minimum.

WHEELS AND TYRES
Jacking up The jack is designed to lift one side of the car at a time. Apply the hand b rake ,
Fig. 1 and block the wheels on the opposite side to that being jacked; use a wood block
jammed tight against the tyre tread.
Remove the plug (1) from the socket in the sill panel
and insert the arm of the
jack into the socket.
Make certain that the lifting arm is pushed fully into the
socket and
that the base of the jack is on firm ground. The jack should lean slightly
outwards at the top to allow for the radial movement of the car as it is raised.
WARNING. Do not work beneath the vehicle with the lifting jack as the sole
means of support. Place suitable supports under the front side-members or
rear
axle to give adequate support and safety while working.
Jack If the jac k is neglected it may be difficult to use in a roadside emergency. Examine
maintenance it occasionally, clean off accumulated dust, and lightly oil the thread to prevent
the formation of rust.
WHEELS
Preventive Owners are recommended to check the wheel nuts on pressed-type wheels for
maintenance tightness each week. Take care not to overtighten (torque wrench setting 45lbf ft
(6·22 kgf m).
Spare wheel The spare wheel is stowed in the well of the Iuggage compartment.
Fig. 2Unscrew the clamp plate (1) to release the spare wheel.
When refitting, position the wheel face down in'the well of the luggage compart-
ment
and retain in position with the clamp plate.
The spare wheel tyre on new cars is inflated above the recommended running
pressure. The pressure must be checked
and adjusted before use.
Pressed type Slacken the four nuts securing the road wheel to the hub; turn anti-clockwise to
Removing and loosen and clockwise to tighten. Raise the car with the jack to lift the wheel
refitting clear of the ground and remove the nuts.Withdraw the road wheel from the hub.
Fig. 3
When refitting the road wheel locate the wheel on the hub, lightly tighten the
nuts (1) with the wheel nut spanner,
and lower the jack. Fully tighten the wheel
nuts, tightening
them diagonally and progressively to the correct torque wrench
setting.
If the spare wheel is to be fitted, remove the centre trim (2) from the original
wheel
and fit it to the wheel in use.
Replace the wheel disc
and jack socket plug.
Wire type Use the spanner and hammer to slacken and tighten the octagonal hub nut.
(When fitted)
Removing and Always jack up a wheel before using the tools and always tighten the hub nuts
refitting fully.
Fig. 4
Hub nuts are marked 'LE FT' or 'RIGHT' to show to which side of the car they
must be fitted,
and also with the word 'UNDO ' and an arrow.
Before replacing a wheel wipe all serrations, threads,
and cones of the wheel and
hub and then lightly coat them with grease. If a forced change is made on the
road, remove, clean, and grease as soon as conv nient.
Maintenance When the car is new, after the first long run or aft r 50 miles (80 km) of short
runs, jack up the wheels and use th
hamm r and spanner to make sure they
are tight.

Wheels and 'Tyres
TYRES
Tyre ma rki ngs Max. load and inflation figures. Tyres are marked with the maximum load and
inflation pressure figures. When fitting replacement tyres ensure that they are
to the same specification
and marking. The permissible load and tyre pressures
are shown on page 73 of this handbook.
Wear indicator. Tyres fitted as original equipment have wear indicators incor-
porated in their tread pattern. When the tyre tread has worn down until 0·06 in
(1'5 mm) of the tread is remaining the wear indicator bar will appear across the
full width of the tread pattern.
Tyre Tyres, including the spare, must be maintained at the pressures recommended
maintenance (see 'GENERAL DATA'); check with an accurate tyre gauge at least once a
week,
and regulate as necessary. Pressures should be checked when the tyres are
cold; do not reduce the pressure in warm tyres where the increase above the
normal pressure is due to temperature. See that the valve caps are screwed down
firmly by hand. The cap prevents the entry of dirt into the valve mechanism and
forms an additional seal on the valve, preventing any leakage if the valve core is
damaged. The spare wheel supplied with new cars is inflated above the recom-
mended running pressure. The pressure must be checked and adjusted before use.
Excessive local distortion can cause the casing of a tyre to fracture and may lead
to premature tyre failure. Tyres should be examined regularly, especially for
cracked walls, exposed cords, etc. Flints and other sharp objects should be
removed from the tyre tread; if neglected, they may work through the cover.
Any oil or grease which may get onto the tyres should be cleaned off by using
fuel sparingly.
Do not use paraffin (kerosene), which has a detrimental effect on
rubber.
Tubeless tyres Normally a tubeless tyre will not leak as a result of penetration by a nail or other
puncturing object, provided
that it is left in the tyre. At a convenient time have
the tyre removed for vulcanizing.
If a small diameter puncture has been made a
temporary repair can be carried out with the tyre manufacturer's plugging kit.
NOTE: The insertion of a plug to repair apuncture in a tubeless tyre must be
regarded as a temporary measure and a permanent vulcanized repair must be made
as soon as possible; In no circumstances should a plug repair be made to the
side wall of a tyre.
BRAKES AND MASTER CYLI'NDERS
Brake and The level of the fluid in the brake master cylinder reservoir is visible through the
clutch master plastic reservoir (1); the level must be maintained up to the position marked (2)
cylinder on the side of the reservoir.
Fig. 1To check the level of the fluid in the clutch master cylinder reservoir (3), remove
the plastic filler cap. The fluid level must be maintained at the
bottom of the filler
neck.
Use only Lockheed Universal Brake Fluid (Series 329S) or Castro" Girling Brake
Fluid; alternatively, use a brake fluid conforming to F.M.V.S.S. 116
D.O .T.3
specification with a minimum boiling-point of 260° C (500°F). Before refitting the
filler caps check that the breather holes (indicated by the arrows) in the caps are
clear. The centre disc (4) of the brake reservoir cap may be removed for cleaning.
Brake pedal A free movement of tin (3'2 mm) (A), measured at the pedal pad must be

Brakes and Master Cylinders
Front brakes Ad just ment of the disc brakes to compensate for fric tion pad wear is automa tic
Fig. 3 and manual adjustment is therefore not required.Before the lining material
(arrowed) has
worn down to the minimum permissible thickness of -rlr in (1·6 mm)
or will have
done so before the next inspection is due, the brake pads must be
renewed. Special equipment is required,
and new pads should be fitted by an
authorized Austin
MG Dealer.
Rear brakes Excessive brake pedal travel is an indication that the rear brake-shoes require
adjusting. The brakes on
both rear wheels must be adjusted to regain even and
efficient braking.
Adjusting Block the front wheels, fully release the hand brake and jack up each rear wheel
Fig. 4 in turn. Turn the adjuster (1) in a clockwise direction (viewed from the centre
of the car) until the wheel is locked, then turn the adjuster back until the wheel
is free to
rotate without the shoes rubbing. Repeat the adjustment on the other
rear brake.
Inspecting Block the front wheels, release the hand brake, and jack up each rear wheel in
rear brake turn. Remove the road wheel and slacken off the brake-shoe adjuster fully.
linings Remove the two countersunk screws (pressed wheels) or the four nuts (wire
wheels)
and withdraw the brake-drum.
Inspect the linings for wear,
and clean out the dust from the backplate assembly
and drum.
Refit the
drum and road wheel and adjust the brake-shoes.
Hand brake The hand brake is auto matically adjusted with the rear brakes. If there is excessive
movement of the
hand brake lever, consult your autho rized Aust in MG Dealer.
Preventive In addition to the recommended periodical inspection of b rake components it
maintenance is advisable as the car ages, and as a precau tion against the effects of wear and
deterioration, to make amore searching inspection and renew part s as necessary.
It is recommended
that:
(1) Disc brake pads, drum brake linings, hoses, and pipes should be examined
at intervals no greater
than those laid down in the Maintenance Summary.
(2)
Under normal operating conditions brake fluid should be changed completely
every 18
months or 19,000 miles whichever is the sooner.
(3) All fluid seals in the hydraulic system and all flexible hoses should be renewed
every 3years or 37,500 miles whichever is the sooner. At the same time the
working surface of the piston and of the bores of the master cylinder, wheel
cylinders, and other slave cylinders
shou ld be examined and new parts fitted
where necessary.
Care
must be take n always to observe the following points:
(a) At all times use the recommended brake fluid.
(b) Neverleave fluid in unsealed cont ainers. It absorbs moisture quickly and
can be dang erous if used in the braking system in this condition.
(c) Fluid drained from the system or used for bleeding is best discarded.
(d) The necessity for absolute cleanlines t hro ughout cannot be over-
emphasized.
Replacing
brake-shoes
or pads
When it becomes necessary to renew the brake-shoes or pads it is essential that
only genuine shoes or pads, with the correct grade of lining, are used. Always
fit new shoes or pads as complete axle sets, never individually or as a single
wheel set. Serious consequences could result from out-of-balance braking due to
mixing of linings.
Replacement brake-shoes
or pads are obtainable from your authorized Austin
MG Dealer.

- the booster battery is of the same nominal voltage as the vehicle battery;
- the interconnecting cables are of sufficient capacity to carry starting curr nt :
- the cables are interconnected one at a time and to the booster battery first ;
- the cables are connected between the battery terminals in the following order:
first, +(positive) to +(positive)
and then - (negative) to - (negative);
- the engine speed is reduced to 1,000 revfmin or below before disconnecting
the boost battery. The vehicle battery must never be disconnected while the
engine is running.
The electrolyte levels (1) in each cell are visible through the translucent battery
case or may be checked by fully raising the vent cover (2)
and tilting it to one side.
The electrolyte level in each cell
must be maintained so that the separator plate
(3) are just covered. To avoid flooding, the battery must not be topped up within
half an hour of it having been charged from any source other than the generating
system fitted to the car.
NOTE: Do not leave the battery in a discharged state for any length of time.
When not in regular use have the battery fully charged, and every fortnight give
ashort refresher charge to prevent permanent damage to the battery plates.
More frequent topping-up of the electrolyte levels may be necessary in hot
weather or when long journeys are made.
To top up the levels raise the vent cover
and pour distilled water into the tro ugh
(4) until all the rectangular filling slots (5) are full
and the bottom of the tro ugh
is
just covered. Press the cover firmly into position; the correct quantity of distilled
water will automatically be distributed to each cell. In extremely cold conditions,
run the engine immediately after topping-up to mix the electrolyte.
DO NOT USE A NAKED LIGHT WHEN CHECKING THE LEVELS and do
not use tap water for topping-up.
Before fitting a radio or any
other electrical equipment, make certain that it
has the correct polarity for installation in this vehicle.
Battery The battery must be kept clean and dry, and the terminals should be smeared
Fig. 1with petroleum jelly. The vehicle must be level when the electrolyte in the cell
is being checked.
IMPORTANT: The vent cover must be kept closed at all times, except when
topping-up. The electrolyte will flood if the cover is raised while either trickle-
or fast-charging the battery.
Fast charging should only be undertaken in extreme
circumstances, and must
not exceed 40 amps for a maximum period of one hour.
A single-cell' heavy discharge tester cannot be used on this type of battery.On
no occasion should the vent cover be detached from the battery.
