➤ Keep the access doors closed and panels in place for safety, quiet running and to ensure correct
cooling air flow.
➤ Immediately stop and secure the machine against restarting if any malfunctions occur. Have any
malfunctions corrected immediately.
➤ Carry out regular inspections:
■ for visible damage and leakage,
■ of safety devices,
■ of components needing to be monitored.
➤ Never operate machines without an air filter when drawing in air from the surroundings.
➤ Outlet valves must be closed when no consumers are connected.
➤ Use only suitable compressed air hoses:
■ that are of the right type and size for the highest permissible machine working pressure,
■ that are not damaged, worn or of reduced quality,
■ that have hose couplings and connections of the right type and size.
➤ Make sure compressed air hoses are de-pressurised before disconnecting from the machine.
➤ Secure the open end of an air hose before applying air pressure. An unsecured hose may whip
and cause injury.
➤ At working pressures >7 bar, compressed air hoses should be secured by a cable to their re‐
spective outlet valves.
Maintenance:
➤ Before commencing any work on the machine, make sure it is shut down, cooled down, pressure-
free and locked off against unwanted starting.
➤ Wear close-fitting, flame-resistant clothing. Wear protective clothing as necessary.
➤ Do not leave any loose components, tools or cleaning rags on or in the machine.
➤ Adhere to the planned intervals for maintenance and exchange of wear parts.
➤ Pressure lines must be fitted correctly. Perform a test run and check for leaks.
➤ Components removed from the machine can still be dangerous.
Do not open or destroy removed components as some (inlet valves, for instance) are powerfully
spring-loaded.
➤ Never remove or change sound damping materials. Ensure that sound damping material is not
damaged or dirty. Replace as necessary.
De-commissioning, storage and disposal:
➤ Drain off fluids and dispose of them according to environmental regulations.
These include, for example, fuel, engine oil and compressor cooling oil and engine coolant.
➤ Dispose of the machine in accordance with local environmental regulations.
3.5.3 Organisational Measures
➤ Designate personnel and their responsibilities.
➤ Give clear instructions on reporting faults and damage to the machine.
➤ Give instructions on fire reporting and fire-fighting measures.
