2.6 Product-specific safety instructions
The following safety instructions apply for chapters 6 to 14.
WARNING
Danger from excessively high pressure!
Danger to life or risk of injury, damage to equipment!
Incorrectly changing the factory pressure setting can cause pressure to increase
beyond the permissible maximum pressure.
Operating the unit above the permissible maximum pressure can cause
components to burst and hydraulic fluid to escape under high pressure.
▶ Changes to the factory settings must only be made by Bosch Rexroth specialist
personnel.
▶ In addition, a pressure-relief valve is needed as back-up in the hydraulic system.
If the axial piston unit is equipped with a pressure cut-off and/or a pressure
controller, this is not an adequate back-up against pressure overload.
