1 Safety
1.4 Safety during installation and commissioning
Continued
Pneumatic or hydraulic related hazards
Loss of pressure in the robot system may cause parts or objects to drop.
Dump valves should be used in case of emergency.
Shot bolts should be used to prevent tools, etc., from falling due to gravity.
All pipes, hoses, and connections have to be inspected regularly for leaks and
damage. Damage must be repaired immediately.
Verify the safety functions
Before the robot system is put into operation, verify that the safety functions are
working as intended and that any remaining hazards identified in the risk
assessment are mitigated to an acceptable level.

Note
The pressure in the complete pneumatic or hydraulic systems must be released
before service and maintenance.
All components in the robot system that remain pressurized after switching off
the power to the robot must be marked with clearly visible drain facilities and a
warning sign that indicates the hazard of stored energy.
