4. Checking the main accumulator : a) Disconnect HP inlet pipe ( 1) from safety
valve.
b) Plug HP inlet pipe fusing p[u~s D
and E ). : c ) Tighten pressure regulator bleed screw.
Disconnect contact breaker lead from coil.
Operate storter,watching the pressure g”“ge :
the pressure should rise steadily and then
appear to stobilize.
Note this reading, which is the inflation
pressure of acc”mulator.
This preksure must equal 62 ‘, To
bars
(899 IE,psi) Corned lead of contact breaker
5. Checking cut-out :
a) Checking cut-out ~TPSSU~~~ : Start engine.
With pressure regulator bleed screw tightened,
examine the pressure gauge.
When pressure stops rising, reading indicates
maximum cut-out pressure.
This pressure m”st be equal to
170 t’5 bars
(2466 ?,73 p:i ). When the c”t-o”t pressure is obtained allow
the engine to nrn for a few minutes in order
to stabilize pressure.
Stop engine.
Examine the pressure gauge and note the fall
in pressure for the next 3
minutes. If the fall in’pressure exceeds
10 bark 4 145psi) check seai of plug D and repeat, the test sequence.
If the result of test is the some, the pressure
regulator is defective,
Replace it 01 repair it.
When cutout takes place, slightly slacken
pressure regulator bleed screw.
The pressure should fall gently then rise (IS~.
soon (IS the HP pump begins to operate.
The minimum reading indicated on tbe pressure
gauge corresponds to the cut-in pressure.
This pressure must be 145 +,5 bars
(2103 ?,73
psi ). If these cut-in and cot-out pressures do
not lie within the given tolerances, check the
pressure regulator.
c) Slacken the pressure regulator bleed screw.
d) Remove plug D and connect HP inlet pipe ( 1)
to safety valve.

7. Checking the safety valve slidevolve :
a) Remove plug from rem suspension outlet on
safety v&e at G b >a.
b ) Disconnect contact breaker lead on coil and
turn engine using stmter : fluid should start
to run through the opening a d N when pressure
reaches
1lLl +o 130 bars ( 1585 to 1885 psi )
c) Slacken pressure regulator bleed screw.

8. Checking the hydraulic brake contml :
m ) Tighten pressure regulator bleed screw.
b) Start up engine.
When cut-out takes place wait a fen: seconds
for the pressure to stobilize.
Stop engine%
Watch pressure gauge and note the pressure
drop in the next 3
minutes. If pressure drop
exceeds 10 bors*( 145 psi ) repeat the test.
If the re< is the same. the broke control
valve is defective : change it.

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.
