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

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

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
