Operate brake pedal until the hydraulic pressure
warning lamp remains on.
Attbat point, read off pressure on pressure gauge.
This should be between 75

out takes place.
Allow pressure to stabilize.
Stop engine.
Examine pressure gauge and note pressure drop

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.

3. Obtaining S( straight line )I steering position :
IMPORTANT In order that the following checks
should be accurate, the zero setting of the turn-
tables must correspond exactly to the strnifih/

The steering should return to the (( straight ahead n
position of its own accord. In this position, check that the following !wo
conditions me met.
1 ) That it is possible to insert pin A (dia =6.5mm)
into the control pinion (rwrrr poiat oi rack J
2) That the values indicated on the rear graduated
rules B ore identical.
1st case : The pin cannot be inserted :
- Slackenvscrews ( -c) and operate eccentric
i 1 i until pin inserts.
NOTE In the case where the eccentric travel
is insufficient :
- Place eccentric ot the centre of its travel.
- Slacken screws (2 ) and rotate steering shaft(!)
until pin inserts.
In the case where this last operation is unsuccess-
ful, it is necessary to move the steering clamp on
the rock control pinion.
2nd case : The values indicated on rear gradu-
ated rules ore different :
- Slacken collars ( 4) and use one of the
sleeves ( 5 1 to obtain an identical value
on Path rear graduated rules 6.
- Bring the Z~IO of graduated sections C
opposite fixed mark <( a )I of each turntable.
- Lock the graduated sections in place using screws D.
