Fluid level must be in area of "MIN." marking (up to 2 mm (0.08 in.)
above or below marking) Operating temperature: above approx. 50 C (122 F) Fluid level must be between "MIN." and "MAX." markings If there is too much fluid in the reservoir, fluid must be extracted.If there is not enough fluid, it is not sufficient to just top off the fluid; the
hydraulic system must also be checked for leaks page 48

(with steering at lock) when carrying out this
test.
In this position the following components must be
checked for leaks:

Pinion seal on steering gear valve housing
All line connections
Rack seals

- Check rack seals with boots pushed back:

- Open boot clamp.
