7

Load pressure accumulator chamber to the prescribed pressure by using the manual pressure pump (4)

 If pressure is too high, it can be corrected by pressing the pressure relief button (3) on the manual pressure pump (4).

 For technical reasons that can not be avoided, adjust the pressure approx. 0.2 bar above the prescribed pressure, because by detaching the manual pressure pump hose (4) in the accumulator filling connection (2), an equivalent pressure drop will occur.
