General
Special safety regulations apply to pneumatic and hydraulic systems.
Note
All components that remain pressurized after separating the machine from the
power supply must be provided with clearly visible drain facilities and a warning
sign that indicates the need for pressure relief before adjustments or performing
any maintenance on the robot system.
Residual energy
• Residual energy can be present in these systems. After shutdown, particular
care must be taken.
• The pressure must be released in the complete pneumatic or hydraulic
systems before starting to repair them.
• Work on hydraulic equipment may only be performed by persons with special
knowledge and experience of hydraulics.
• All pipes, hoses, and connections have to be inspected regularly for leaks
and damage. Damage must be repaired immediately.
• Splashed oil may cause injury or fire.
Safe design
