vessel or auxiliary installed outside the machine to contain air above atmospheric pressure shall be
protected by a pressure relieving device or devices as required.
13. Yearly inspect the air receiver. Minimum wall thickness as specified in the instruction book must be
respected. Local regulations remain applicable if they are more strict.

Safety precautions during maintenance or repair

Precautions during maintenance or repair
1. Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.).
2. Use only the correct tools for maintenance and repair work.
3. Use only genuine spare parts.
4. All maintenance work shall only be undertaken when the machine has cooled down.
5. A warning sign bearing a legend such as "Work in progress; do not start" shall be attached to the starting
equipment.
6. Persons switching on remotely controlled machines shall take adequate precautions to ensure that there
is no one checking or working on the machine. To this end, a suitable notice shall be affixed to the remote
start equipment.
7. Close the compressor air outlet valve and depressurize the compressor before connecting or disconnecting
a pipe.
8. Before removing any pressurized component, effectively isolate the machine from all sources of pressure
and relieve the entire system of pressure.
9. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions against
toxic vapours of cleaning liquids.
10. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts
and exposed openings with a clean cloth, paper or tape.
11. Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely
purged, e.g. by steam cleaning, before carrying out such operations. Never weld on, or in any way modify,
pressure vessels.
12. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the
machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has
elapsed; this to avoid the risk of spontaneous ignition of the oil vapour when air is admitted.
13. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
14. Make sure that no tools, loose parts or rags are left in or on the machine.

precautions during maintenance.
These precautions apply to machinery processing or consuming air or inert gas.
Processing of any other gas requires additional safety precautions typical to the application
which are not included herein.
Some precautions are general and cover several machine types and equipment; hence
some statements may not apply to your machine.
All responsibility for any damage or injury resulting from neglecting these precautions, or
non observance of the normal caution and care required for installation, operation,
maintenance and repair, even if not expressly stated, will be disclaimed by the
