3.5.2.3 Commissioning, operation and maintenance
During commissioning, operation and maintenance you may be exposed to dangers resulting from
electricity, pressure and temperature. Careless actions can cause accidents with severe adverse
health effects.
➤ The machine should be operated by authorized personnel only.
➤ Wear close-fitting, flame-resistant clothing. Wear protective clothing as necessary.
➤ Switch off the machine and lock against unexpected activation.
➤ Depressurize all pressurized components and enclosures and then verify.
■ Wait until the machine has automatically vented.
■ Carefully open the compressed air outlet valve.
■ Check: The pressure gauge must read 0 psig!
➤ For maintenance and repair work, isolate machines with "automatic start/stop" (Option ob) from
the compressed air network and secure against automatic start.
➤ Allow the machine to cool down sufficiently.
➤ Do not open any body panels whilst the machine is switched on.
➤ Do not open or dismantle any valves.
➤ Only use spare parts approved by KAESER for use in this machine.
➤ Operate the machine only in technically sound condition.
➤ Carry out regular inspections:
■ for visible damage and leaks,
■ of safety devices,
■ of the EMERGENCY STOP push button,
■ of parts that require monitoring.
➤ Pay particular attention to cleanliness during all maintenance and repair work. Cover compo‐
nents and exposed openings with clean cloths, paper or tape to keep them clean.
➤ Do not leave any loose components, tools or cleaning cloths on or in the machine.
➤ Components removed from the machine can still be dangerous:
Do not attempt to open or destroy any components taken from the machine.
➤ Self-locking nuts removed for the installation must not be reused but replaced with new nuts,
because the non-positive safety is no longer ensured.
➤ Only use suitable compressed air hoses.
Compressed air hoses must meet the following requirements:
■ They must be of the right type and size for the highest permissible working pressure of the ma‐
chine,
■ They must not be damaged, worn or of inferior quality,
■ use only hose couplings and connections of the right type and size.
➤ Wear protective gloves when connecting or disconnecting compressed air hoses.
➤ Ensure that compressed air hoses are vented before disconnecting them from the machine.
➤ Secure the open end of an air hose before applying air pressure. The free end of an unsecured
hose may whip and cause injury.
