PREPARATION 1.
First ensure :
- that hydraulic reservoir filter is clean.
- that hydraulic fluid is ot normal running tempe-
rature ( Carry 0~1 a road lent first i/ vt4icie

mid ). 8 2. Draining the circuits :
Place manual height control lever in ion, posirios,
Slacken pressure regulator bleed screw ( 1 ). 3. Fitting pressure gouge A :
Disconnect the tube (2) HP outlet from pressure
regulator.
Connect the following assembly into the circuit :
pressure gaoge A, 3way union B and pipe C
between pipe ( 2) and the pressure regulator.
This ass~nzhly mrtst remain in positioa /brougbo~~l
the test. IMPORTANT :
The testing kquance described below must be
followed.
If after the test, a component appears defective,
either replace it or repair it before proceeding
to the next test.

Downloaded from www.Manualslib.com manuals search engine 9. Checking pressure switch (1) : Test procedure is the sctme as for checking
broke control.
Turn engine to obtain cut-out pressure.
Stop engine.
Operate brake pedal until the hydraulic pressure
warning lamp remains on.
Attbat point, read off pressure on pressure gauge.
This should be between 75
and 95 bars ( 1088 ta.
1378 psi 1, inclusive.
If not, change the pressure switch.
10. Checking the Front suspension : Slacken.pressure regulator bleed screw.
Remove plug E and connect front suspension
supply pipe (2 ) to safety valve.
Tighten pressure regulator bleed screw.
Start engine.
Put manual height control in
rronnaf rtmni>rp positim. Wait until the front end of vehicle rises and cut-
out takes place.
Allow pressure to stabilize.
Stop engine.
Examine pressure gauge and note pressure drop
during wperiod of 3
minutes. If it exceeds 10 bars
( 145 psi 1, check once more.
If the result is confirmed check the following
c?mponenG to determine which one is leaking :
either the front corrector
or the suspension cylinders (one or both ).
Testing the 3 components should be carried out by
eliminating each one in turn.
(I) Testing the front height cmwclor : Loosen pressure regulator bleed saew.
Put manual control in
loin position. Disconnect supply pipe (3 ) for front cylinders
from 3-way union (4 ).
Plug tube (3 ) using plug D ( female 1.
Tighten pressure regulator bleed scwe.
Place manual height control in normal running
posiGon:Start engine.
Allow pressure to stabilize.
Stop engine.
Read off pressure drop on pressure qtruqe.
If this drop in pressure is greater than
10 bars (
145 psi ) during a period of 3 minutes, repeat
test. If the result is confirmed, the front height
corrector is defective : change it.
Remove plug and connect pipe (3 ) to 3roy
union
(4 ).

Put manual height control in /VII. position
Disconnect front left-hand cylinder supply
pipe ( 1 ) from 3~woy union (2 ).
Plug 3-way union opening using plug E.
Repeat test as described in preceding parograpb.
If the front left suspension cylinder is defective
replace 01 repair it.
Remove plug E.
Fit supply pipe ( 1 ).
If after testing the front height corrector and the
left-hand front suspension cvlinder, the drop in
pressure persists, the front right-hand cylinder
is defective.
Replace or repair it. Il.
Checking the rear suspension :
Slacken pressure regulator bleed screw.
Put manual height control in IOU pnsi!ios,
Remove plug E.
Connect rear suspension supply pipe (?) to
safety valve.
Disconnect rear brake supply pipe (4) from
brake valve.
Plug oriilce of pipe using plug D.
Tighten pressure regulator bleed screw
Place manual height control in aorwnl rrruniug
posilio,,.
Proceed as for test of front suspension.
12. Slacken pressure regulator bleed screw.
Disconnect 3-way union B together with pressure
gauge A and pipe C.
Fit connecting pipe of safety valve to pressure
regulator.
Tighten pressure regulator bleed screw.

bubble (3 1 is centred.
b) Note in blur scnle (at o a n ) the reading of the
comber rmqle.
c ) Carry out the same operation on the other
wheel.
Comber angle must be between 0’ + 13’ - 29’
