PRECAUTIONS WHEN CARRYING OUT WORK ON THE CAR
1. Battery :
a) Disconnect the negative terminal first, then the positive one.
b) Ensure the battery is properly connected, with the negative terminal being connected
to earth.
c) Carefully connect both leads to the battery terminals, the negative lead being connected
last.
Before connecting the negative lead ensure that there is no flow of current. This can
be established by briefly touching the negative terminal pith the lead end : sparks
indicate a short circuit which must be corrected first.
d) Before using the starter ensure that the two leads are correctly tightened on their
respective terminals. $ 2. Alt ernator-Regulator :
a) Do not rotate the alternator unless it is connected to the battery.

2
2 b) Before connecting the alternator ensure that the battery is correctly connected
2 (negative terminal to earth ).
c) Do not check the operation of the alternator by short-circuiting either the positive or
the u EXC )) terminals and the earth terminal.
d) Take care not to reverse the leads connected to the regulator.
e) Do not attempt to re-energize the alternator : this is never necessary and in any case
would damage both the alternator and the regulator.
f ) Do not connect a suppressor capacitor at the u EXC )) terminal of the alternator or the
regulator.
g) Do not connect a charging unit to the battery and never carry out arc welding ( or spot
welding) on the car chassis unless both the positive and the negative leads are
disconnected from the battery. 3. Ignition coil :
4. Q.I. Headlamps :
a) Connect the supply lead of the coil to the external ballast resistor terminal and not to
the coil itself.
b) Connect the suppressor with a jump lead to the feed terminal of the coil. Only fit the
suppressor recommended by the factory.
a) Only replace a Q.I. bulb with the headlamps switched off. After having used the head-
lamps, it is wise to let them cool down for five minutes before handling.
b) Do not touch a Q.I. bulb with bare fingers. Any fingerprints on the bulb must be cleaned
off with soapy water and the bulb dried with a lint-free cloth.

\~ir/~rol 6jr/rol,/ir j111icl ( LHM ) is the only suitable type and must be used to the exclusion of all others in the
hydraulic system of the car.
This LHM fluid is gt~‘~,l

Suitable components are identified by their grcc’r/ colo/~r and may only be replaced by gc~rttri~ro wplor-c~t~~c~nf
col,,pollc,l/fs painted or marked in green.
All rubber components (joints, hoses, diaphragms, etc . . . ) are of a
spvcirfl qtrnlif), ior ~/.SCJ wifh idlfM (Iuid and are
identified by their white or green colour, 3. STORAGE :
ix Components must be stosed /11i1 o/ /Irlirl nr~tl blor~k~rl o!j: Like the piping they must be protected against shock
E and the inqress of dust
7 Rubber tubing and joints must be stored away from dust. air, light and heat.

b) and that the 111’ c-ire-/ii/ is ////(/(jr /~I.(Jss/II.(J. as follows :
With the engine at idling speed :
- Unscrew the pressure-release screw on the pressure requlator by one or one and one half turns : a sound
, of leakage should be heard from the requlator.
= Retighten the release screw : cut-out must occur which results in a reduction in the running noise
emitted by the H P pump.
If not check in the following sequence
- that there is sufficient fluid in the reservoir,
- that the reservoir filter is clean and in good condition,
= that the H.P pump is primed and there is no air leak on the suction side of the pump,
- that the release screw of the pressure requlator is correctly tightened

5. PRECAUTIONS TO BE TAKEN BEFORE WORKING ON THE HYDRAULIC SYSTEM :
a) (.~rvJuI/)~ CIVOII the area of work, the unions and the unit to be removed
Disconnect the lead from the negative terminal of the battery
Only use petrol or lead-free petrol for cleaning.
b ) I~~J/VNSO
the /)twsure in the circuits
- Place the vehicle in the G /arc B
position. stop the engine.
- Slacken the Pressure Requlator release screw.
Wait until the front of the car has reached the low position 6, PRECAUTIONS TO BE TAKEN DURING REMOVAL :
a) t3lnuk o!! the w~~tnl pi/~es with plugs, and rubber tubes with round pins of the correct diameter
b)
t3lmk of/ //IV op,c,/li,lg.s of components with pluqs of the correct diameter
NOTE : Plugs and pins must be carefully cleaned before insertion. 7.. CHECK OR TEST OF HYDRAULIC UNITS :
- Use 3654-T t~sf hc~~c-h equipped and designed for use with LHM fluid
This bench is /)ciitltc’d ~IY’~‘~/ and its accessories are marked in green.
- Never use the bench with another fluid or for testing components operating with another fluid (units of a (( D ))
car using LHS2 for instance ).
NOTE The (< Le Bozec )) pump used on test benches for checking DIESEL injectors can be resorted to for
testing components operating with LHM mineral fluid provided that the bench is cleaned first. 8. PRECAUTIONS TO BE TAKEN DURING REFITTING :
E steel pipes must be blown through with compressed air,
5 rubber tubes and joints must be washed in petrol or white spirit and then dried with compressed air,
= hydraulic units must also be cleaned with petrol or white spirit and blown through with compressed air.
NOTE Renew all joints and seals during refittinq .
b
) 12rlbrijicntim :
- Follow the indications as stated in the operations in the Manual..
- Joints and internal parts must be liqhtly oiled hefore fitting ( use mineral fluid LHM only )
L If parts in contact with hydraulic units have to be qreased use a mineral grease only ( as employed for
Cardan shafts or bearings ).

I To connect a union proceed as follows :
- Position sleeve-seal (( a u lightly coated with
L,HM fluid; this sleeve seal must not reach the
extremity of pipe (( b )).
- Centre the pipe in the housinq by lininq it up
with the axis of the hole, avoidinq all stress.
( Ensure that the end u b )I of the pipe enters
into the smali bore C< c )> j.
Start screwing in the union nut by hand.
- Tiqhten nut moderately : excessive force could
cause a leak because of deformation of the pipe
NOTE Tiqhteninq torques :
3.5 -mm pipe t 5.8 to 6 6 ft lbs
4 5 mm pipe 5 8 to 0 mN ( 0.8 to.0 9 ‘1 kg )
6 6 to 8 0 ft.lbs
6. O-mm pipe

9 to 11 mN (0 9 to 1 1 m.kg ) c ) Fittilzg :
I Only use joints of a quality compatible with LHM mineral fluid.
The design of the various seals ensures that their sealing action increases with fluid pressure The oiltiqhtness e
is therefore not improved by greater tiqhtness of the unions
2 To connect a rubber tube a rubber rinq of suitabie diameter has to be positioned between thr, tube and the hose

On completion of work on hydraulic units or the system itself check the followinq :
h) ‘1’11~ C./CJ~~~IIC-C, I~c,lrt,c,c,rt I/J<
pipvs : pipes must not touch one another or any other component, nor may any other
unit, whether fixed or movable, exert any stress on them.

OBSERVATIONS :
a) This operation can be sarried out by sleeving the damaged tube
b) If two sleeves are to be located on one length of tube the interval between them must be about 30 in in order
to retain the flexibility of the tubing.
c) Obtain a bottle of Rilsan adhesive ( 125 cc ) sold by the BOYRIVEN firm , 37 bis rue de Villiers _
92200 u NEUILLY sur SEINE - Tel. 624-36-11
( Rilsan adhesive harms the skin : avoid touching it with the fingers, use a wooden spatula instead
1. Cut the tubing and roughen the ends over a lenqth of some 3.5 in. with abrasive paper N” 600
2. Carefully deqrease the roughened ends and the sleeve with trichlorethylene
3. Heat the Rilsan adhesive in a water-bath to raise its temperature to 60°C.
Do root c~sc-c~c~d /his Icv~p~~rntriw.
NOTE : This operation is essential to cut down drying time
4, Coat the ends of the tube and the inside of the sleeve with adhesive.
Leave the parts to dry for a few minutes.
Insert the ends of the tube into the sleeve.
).
Allow the assembly to dry for three to four hours before using the repaired tube aqain.
