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.
