➤ Do not leave any loose components, tools or cleaning rags on or in the machine.
➤ Do not open or destroy disassembled parts.
Disassembled parts may represent a safety hazard.
➤ Self-locking nuts removed for the installation must not be reused but replaced by new nuts, be‐
cause the non-positive safety is no longer ensured.
➤ Use only suitable compressed air hoses.
Compressed air hoses must meet the following requirements:
■ they are of the right type and size for the highest permissible machine working pressure,
■ they are not damaged, worn or of reduced quality,
■ they have couplings and connections of the right type and size.
➤ Wear protective gloves when connecting or disconnecting compressed air hoses.
➤ 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 > 100 psi, compressed air hoses should be secured by a cable to their
respective outlet valves.
➤ Connect and operate only suitable air tools.
■ The air tools must meet the set output pressure of the machine.
■ Use a pressure reducer for air tools requiring a lower pressure.
■ Use compressed air tools only with the pressure appropriate for its purpose (tool working pres‐
sure).
