The brake pedal operates the brake hydraulic systern and applies the brakes onall four wheels, also bringing the stop warning lights into operation when theignition is switched on.

Hand brake The hand brake is of the pull-up lever type, operating mechanically on the rear(4) wheels only. To release the hand brake pull the lever upwards slightly, depress

the button on the end of the lever and push the lever down.

Gear lever(5)

The gear positions are indicated on the lever knob. To engage reverse gear movethe lever to the right in the neutral position until rcsistance is felt, apply furtherside pressure to overcorne the resistance and then move it backwards to engagethe gear. Synchromesh is provided on second, third, and fourth gears.

With the diagonal adjuster atthe sill, adjust the lap belt until the belt fits comfortably and there is just roornto pass a hand between the diagonal belt and the chest. Slight readjustment maybe necessary during use.

Care of the When not in use, hook the buckle on the long belt into the stowing bracket (3)belts mounted on the hood hinge pIate, and attach the magnetic buckle on the short

belt to the seat frame. If ar any time the webbing is unthreaded frorn the bracketsand adjuster, ensure that it is re-threaded correctly as shown (4).

If the belts become soiled, sponge with warm water using a non-detergent soapand a110wto dry naturally, Do not use caustic soap, chemical cleaners or deter-gents for cleaning; do not dry with artificial heat or by direct exposure to the sun.

No unauthorized alterations or additions to the belts should be made: do notbleach or re-dye th~ belt webbing. Inspect the webbing periodically forsigns ofab~aslOn, cuts~ fraying, and general wear; pay particular attention to the fixingpoínts and adjusters. Replace belts that are defective or have been subjected tosevere strain in an accident.

HEATING AND VENTILATING

Fresh-air The heating and ventilating system is designed to provide fresh-air, either heatedheater by the engine cooling system or at outside air temperature, to the car at floor

leveI and, for demisting and defrosting, to the windscreen.

Air enters through a forward-facing intake; the ram effect caused by lhe car'smotion provides air for the heater's requirements at speeds above 25 rn.p.h,(40 km.p.h.). A blower motor is provided for use at lower speeds or when agreater quantity of air is required.

Air Two doors, located one at each side of the gearbox tunnel, control distributiondistribution 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.

Heater controlvalveFig. 1

A valve contro11ing the flow of coolant through the heater unit is fitted at therear of the cylinder head. The valve is opened by turning it in an anti-clockwisedirection when heating is required or shut off by turning clockwise when thesystem is to be used for cool air ventilation.

Air-intake The knob 'H' on the fascia panel controls the booster blower motor and alsocontrol a shut-off valve incorporated in the air intake. This valve prevents fumes entering

Fig. 2 the car when driving in heavy traffic.

To switch on the blower, tum the knob in a clockwise direction.

To dose the shut-off valve, switch off the blower and pull out lhe knob. Theblower motor .cannot be switched on again until the shut-off valvc i~ rcturned tothe open position.

RUNNING INSTRUCTIONS

High- This engine is a highly developed unit and, as such, specialized maint nuncc iscompression required to maintain it at the peak of its mechanical efficiency. Recommcndntions

engine (8'8 : 1) on the sparking plugs, ignition settings, and fuel to be used, are given uud il istressed that failures are bound to occur if these are not strictly adhei 'li lo,Particular care is needed owing to the high compression ratio of the 'l1~illrwhich makes it extremely sensitive to variations in fuel, ignition timing, and h '1\1range of the sparking plugs.

The range of fuels, sparking plugs, and ignition settings is narrower than lho erequired with lower compression engines and it is essential that the rnixturcshould always be correct, particularly never over-weak at maximum load orpower.

High-compression engines are very sensitrve to variations in spark advance(over-advance) and to fuel/air ratio (mixture). Variation in these settings willincrease the combustion temperature, and if the variation is excessive pre-ignition will cause high shock waves resulting in damage to the engine.

The engine should be decarbonized at regular intervals as excessive deposits ofash in the combustion chambers can cause pre-ignition diffículties.

Choice of fuel The octane number of a motor fuel is an indication given by the fuel techníciansH. C. engine of its knock resistance (pinking), High-octane fuels have been produced 10

improve the efficiency of engines by allowing them to operate on high com-pression ratios, resulting in better fuel economy and greater power. Owing Ithe high eompression ratio of the engine, fuels with an octane rating below 94 arenot suitable, Should it be neeessary to use a fuel with a lower oetane numbcr,the ear must be used very earefully until the eorreet fuel ean be obtained.

It is necessary to use Premium grade fuels with oetane ratings of 97 to 99 whenoptimum performanee is required.

Fllling up with When filling up with fuel do not fil! the tank until fuel is visible in lhe fillerfuel intake tube. Should this be done and the car left in the sun, there will be a con-

siderable risk of fuel leakage due to expansion, and eonsequent danger fromexposed fue!. lf inadverlently overfilled and the car is to be parked, take carcto park it in lhe shadc with the filler intake as high as possible.

Wait until the engine has stopped turning before re-using the starter.

If after a reasonable number of attempts the engine should fail to start, switchoff the ignition and investigate the cause. Continued use of the starter when theengine will not tart not only discharges the battery but may also damagc lhestarter.

If the starter pinion fails to engage with the flywheel ring, or fails to disengagcwhen the engine starts, the starter will emit a high-pitched whine ; release theignition key irnrnediately.

Always use the minimum setting for the shorte t possible time.

As soon as possible after lhe engine has started, push the control completelyhome.

To obtain a fast engine idling speed, set lhe control to within the first t in. (6mm.)approx. of its initial movement.

The light should glow when the ignition is switched on, and go out and stay outat ali times while the engine is running above normal idling spccd, Failure to doso indicates a fault in the battery charging system. Check that the fan belt iscorreetly tensioned before consulting your Distributor or Dcalcr,

The gauge should register a pressure as soon as the enginc i started up, Thepressure rnay rise above 70 lb.jsq, in, (4'92 kg.rcm.") when the enginc is startedfrorn cold and as the oil is circulated and warmed the prcssure should then dropto between 40 and 70 Ib.jsq. in. (2,81 to 4·92 kg.jcrn.") at normal running speedsand to approximately 20 lb.jsq. in. (1-4 kg.jcm.") at idling speed.

Should the gauge fail to register any pressure, stop the engine immediately andinvestigate the cause. Start by ehecking the oil level.

Warming up Rcscarch has proved that lhe practice of warrning up an engine by allowing it loidle slowly is cfefinitely harmful. The correct procedure is to let the engine runfairly Iast, approximately 1,000 r.p.m., corresponding to a speed of about15 m.p.h, (24 krn.p.h.) in top gear, so that it attains its eorrect working tempera-ture as quickly as po sible. Allowing the engine to work slowly in a cold statcleads to excessive cylindcr wear, and far less darnage is dane by driving lhe carstraight on to the road Irorn cold Ihan by letting the engine idle si wly in lhegarage.

Running Instructions

Temperature When the engine is running the gauge indicates the temperature of lhe .oolantgauge leaving lhe cylinder head.

As overheating may cause serious damage, the readings should be nOI'lI 1I11d

after the initial rise in temperature during the warming up period any suddcnupward change in the reading calls for imrnediate investigation.

Running in The treatment given to anew car will have an important bearing on its subsequentlife, and engine spee,âs during this early period must be limited. The followinginstructions should be strictly adhered to.

During the first 500 miles (800 km.):

DO NOT exceed 45 m.p.h. (72 km.p.h.).

DO NOT operate at full throttle in any gear.

DO NOT allow the engine to labour in any gear.

Tachometer For normal road work, and to obtain lhe most satisfactory service from yourengine, select the appropriate gear· to maintain engine speeds of between 2,000and 4,500 r.p.m.

When maximum acceleration is required upward gear selections should bc rnadcwhen the needle reaches the yellow sector (5,500-6,300 r.p.m.). Prolongcd orexcessive use of the highest engine speeds will tend to shorten lhe life of lheengine. Allowing the engine to pull hard at low engine speeds must be avoidcdas this also has a detrimental effect on the engine.

The beginning of the red sector (6,300 r.p.m.) indicates the maximum safe pecdfor the engine.

Never allow the needle to enter the red sector.

W t br k s Wheo the vehicle is boiog washed or driven through water the brake lining. maybccome wet. To dry thern, apply the brakes several times with the vehicle movinslowly, Driving with wct brakes is very dangerous.

CLEANING

Coachwork Regular care of the body finish is oecessary if the new appearance of the carexterior is to be maintained against the effects of air pollution, raio, and mudo

Wash the bodywork frequently, usiog a soft sponge and pleoty of water con-taining a mild detergent. Large deposits of mud must be softened with watcrbefore usiog the sponge, Smears should be rernoved by a second wash in cleanwater, aod with the spooge if necessary. When dry, clean the surface of the carwith a damp chamois-leather. lo addition to the regular maintenance, specialatteotion is required if the car is driven in extreme conditions such as sea spray,or 00 salted roads. In these conditions and with other forms of severe contamina-tion an additional.washing operation is necessary, which should include underbody hosing. Any damaged areas should be immediately covered with paint anda complete repair effected as soon as possible. Before touching-in light scratchesand abrasions with paint thoroughly cleao the surface. Use petroljwhite spirit(gasoline/hydrccarbon solvent) to remove spots of tar or grease.

The application of BMC Car Polish is ali that is required to remove traffic filrnand to ensure the retentioo of the new appearance.

Bright trim Never use ao abrasive on stainless, chromium, aluminium, or plastic bright partsand on no account clean them with metal polish. Remove spots of grease or tarwith petroljwhite spirit (gasoline/hydrocarbon solvent) aod wash frequentlywith water cootaioiog a mild detergent. When the dirt has been removed polishwith a clean dry cloth or charnois-leather until bright. Any slight tarnish foundon staioless or plated parts which have not received regular washing may beremoved with BMC Chrome Cleaner. An occasional application of minerallight oi! or grease will help to preserve the finish, particularly during winterwhen salt may be used on the roads, but these protectives must not be appliedto plastic finishes.

Windscreen If windscreen smearing has occurred, it can be removed with 13MC ScreenCleaner.

Interior Decosol Interior Cleaoer is recornmended for cleaning the interior of your car,and may be safely applied to carpets, upholstery and roof linings. Decosol mustnot be used on painted surfaces.

Carpets. Remove surface dirt with a semi-stiff brush or a vaCUUJ1lcleaner, ApplyDecosol, diluted with ao equal quantity of water, brush vigorously with a sem i-stiff brush then clean off using a moistened sponge or cloth.

Upholstery and roof Iinings. Apply neat Decosol with a soft brush or cloth, lcavcfor five minutes, then wipe clean using a moistened sponge or cloth,

Hood To clean the hood it is only necessary to use soap and water, with a oft brushto remove any ingrained dirt. Frequent washing with soap and water considerablyimproves lhe appearance and wearing qualities of the hood, anel il hould bewashed at least as often as lhe rest of the car.

Do not use caustic soaps, dctergents, or spirit cleaners to clean the hood or thehood back -light,

Frost Water, when it freezes, expands, and if precautions are not taken therc i con-precautions siderable risk of bursting the radiator, cylinder block, or heater (where fiucd).

Such damage may be avoided by adding anti-freeze to the water.

Warning.v-Whena heater unit is fitted an anti-freeze solution must be added in lhecooling system since no provision is made for draining the heater.

Do not use radiator anti-freeze solution in the windscreen washer.

Anti-freeze Anti-freeze can remain in the cooling system for two years provided that lhesolutions specific gravity of the coolant is checked periodically and anti-freeze added as

necessary. The specific gravity check should be carried out by an authorizedDistributor or Dealer.

Top up only when the cooling systern is at its normal running lemperature inorder to avoid losing anti-freeze due to expansion.

After lhe second winter the system should be drained artd f1ushed. Refer to lheínstructions given for draining the cooling system then clean out the systernthoroughly by f1ushing water througb the radiator passages using a hose insertedin the radiator filler orifice.

Before adding the recornrnended anti-freeze make sure that the cooling system iswatertight ; examine ali joints and replace any defective hose with new.

Only anti-freeze of tbe ethylene glycol or glycerine type is suitable for use inthe cooling systern. We recommend owners to use Bluecol Anti-freeze (non-corrosive) in order to protect the cooling systern during frosty wcalher andreduce corrosion to a minirnum. We also approve lhe use of any anti-Ircczewhich conforms to Specifieation B.S.3J51 or B.S.3152.

Any oil or grease which may get onto the tyres should be cleaned off by using fuelsparingly. Do not use paraffin (kerosene), which has a detrimental effcct nrubber.

With tubeless tyres penetration does not norrnally result in deflation and thetyres should be repaired when convenient. Penetrations by objects of smalldiameter can be repaired with the tyre manufacturer's plugging kit, while moreextensive damage requires the removal of the tyre for vulcanizing.

Tubala tyra The insertion of a plug to repair a puncture in a tubeless tyre must be regarded asr pairs a temporary repair only and a permanent vulcanized repair must be made as soon

as possible. .

When repairing tubes have punctures or injuries vulcanized. Ordinary patchesshould only be used for emergencies.

Vulcanizing is absolutely essential for tubes manufactured from synthetic rubber.

Radial-plytyres (SP)

Always use a tubular box spanner to avoid possible damageto the insulator, and do not under any circurnstances use a movable wrench.Never overtighten a plug, but ensure that a good joint is made between the plugbody, washer, and cylinder head. Wipe clean the outside of the plugs beforcreconnecting lhe H.T. leads.

When fitting new sparking plugs ensure that only the recommended type andgrade are used (see 'GENERAL DATA').

Fig. 1 Oil system maintenance

Checking The levei of the oil in the engine sump is indicated by the dipstick (3) on theengine oil levei right-hand side of the engine. Maintain the levei at the 'MAX' mark on the dip-

stick and never allow it to fali below the 'MIN' mark.

The filler (2) is on the forward end of the rocker cover and is provided with aquick-action capo The filler cap also incorporates a filter for the closed-circuitcrankcase breathing intake.

The oillevel should always be checked before a long journey.

ENGINE

Draining To drain the engine oil, remove lhe drain plug (1) located on lhe right-hand sideat the rear of lhe sump. This operation should be carried out whilc lhe engineis warm.

Clean the drain plug; check that its copper sealing washer is in ti satisfactorycondition, and refit.

Filling Fill lhe engine with the correct quantity of oil. Run lhe cngine for 11 short whilethcn allow it to stand for a few minutes before checking lhe lcvct with lhe dip-stick,

Refill the engine with the correct quaruity of a recornmended lubricant, starengine and check for oil leakage. If difficulty is experienced when changing thcoil filter, consult your Distributor 01' Dealer.

Dynamo To lubricate the dynamo add a few drops of oil through the central hole (arrowcd)lubrication in the rear bearing hou ing. Avoid overlubrication.

Fig.3

Fan beltChecking When correctly tensioned, a deflection, under moderate hand pressure, of t in.

(13 mm.) approximately should be possible at the midway point of the longestbelt run between the pulleys.

Adjusting To adjust the belt tension, slacken the dynamo securing bolts (1), and hingeFig. 4 link bolt (2). Move the dynamo to the required position, using only hand pressurc,

Avoid overtensioning. Tighten the securing bolts (1), and hinge link bolt (2).

Valve rockerclearance

Checking Remove the rocker cover and insert a ·012 in. ('305 mm.) feeler gauge betweenFig. 5 the valve rocker arms and valve stems (inset). The gauge should be a sliding fit

when the engine is cold. Check each clearance in the following order:

Check No. 1 valve with No. 8 fully open. Check No. 8 valve with No. 1 fully open3 6" u 6" 3"5 4" 4 5 ••2 7" 7 2 "

Adjusting Slacken the adjusting screw locknut 00 the opposite end of the rocker arm androta te the screw clockwise to reduce the clearance or anti-clockwise to increase it.Retighten the locknut when the clearance is correct, holding the screw againstrotation with a screwdriver.

Engine

Closed-circuit Crankcase breathing is by a direct connection from the oil separator to thebreathing carburetters. Servicing is confined to the oil filler cap, as recommended in the

Oil til/er cap maintenance sumrnary.Fig.6

An air filter is incorporated in lhe oil filler cap (I). The cap and filter are renewedonly as a complete assembly.

Carburetters Each damper reservoir must be topped up periodically with thin cngine oil.Lubrication Under no circumstances should heavy-bodied lubricant be used. Unscrcw lhe damper

Fig. 7 cap, withdraw the damper, and top up the reservoir until the oil levei (arrowed)is t in. (12 mm.) above the top of the hollow piston rodo Pu h lhe damper as-sembly back into position and screw lhe cap firmly into lhe re crvoir.

Fig.8As the needle size is determined during engine development, tuning of thcarburetters is confined to correct idling setting. Slacken the actuating arms 011

the throttle spindle interconnection. Close both throttles fully by unscrewingthe throttle adjusting screws (1), then open each throttle by screwing down eaehscrew one turno

Remove the suction chamber (4) and piston assemblies, marking each to ensurereplacement in their original positions, remove the air c1eaners and disconnectthe mixture control cable. Screw the jet adjusting nuts (2) until each jet is fíushwith the bridge of irs carburetter, 01' as near to this as possible (both jets beingin the same relative position to lhe bridge of their respective carburetters).Replace the pistons and suction chamber assemblies, and check that the pistonsfali freely onto the bridge of lhe carburetters (by means of the piston liftingpins (3)). Turn down each jet adjusting nut two complete turns (12 fiats).

Restart lhe engine, and turn the throttle adjusting screws to give the desiredidling speed by moving each screw an equal amount. By listening to the hiss inthe intakes, adjust lhe throttle adjusting screws until the intensity of the hiss issimilar on both intakes. This will synchronize lhe throttles.

When this is satisfactory, the mixture should be adjusted by screwing each jetadjusting nut, up to weaken, or down lO enrich by the same amount until thefastest idling speed consistent with even firing is obtained. During this adjustmentit is necessary to press the jets upwards and ensure that they are in contact witht he adjusting nuts,

As the mixture is adjusted the engine will probably run faster and itrnay therc-fore be necessary to uncrew the throttle adjusting screws a litt Ic, each by thesame arnount, to reduce lhe speed,

Now check the mixture strength by lifting the piston of the front carburetter byapproximately n in. ('75 mm.) when:

(1) If the engine speed increases, the mixture strength of the front carburetteris too rich.

(2) li the engine speed immediately decreases, the mixture strength of thefront carburetter is too weak.

(3) li the engine speed momentarily increases very slightly, the mixturestrength of the front carburefter is correet.

Repeat the operation at the rear carburetter, and after adjustment rc-check thefront carburetter, since both carburetters are interdependent.

When the mixture is correct the exhaust note should be regular and .vcn, Ir it isirregular, with a splashy type of misfire and colourless cxhaust, thc mixture is tooweak. If there is a regular ar rhythmical type of misfirc in lhe sxhaust beat,together with a blackish exhaust, then the mixture i too rich,
