                                         WARNING

Before starting work on the hydraulic

system, the pressure must first be

relieved in a controlled manner. The

system has an overpressure of 14 bar, which means that the oil will be forced out if a union is opened without relieving the system. This means there is a risk of eye injuries, etc. Wear protective

goggles.

The accumulator tank is filled with

nitrogen at an overpressure of

approximately 8.5 bar. This means that the accumulator tank is pressurised

even if there is no oil in the system.

Hydraulic oil is aggressive; avoid skin contact at all times. Wear protective

gloves.

IMPORTANT! Handle empty accumulator tanks in compliance with local regulations.

compressed air. The connections on the

master cylinder and centering cylinder must then be undone.

5   Remove the protective cap on the gas side of the accumulator tank.

6   Undo the plug on the gas side max 2 turns and allow the gas to seep out.
