Safety precautions during maintenance or repair

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
manufacturer.
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.

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 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 any 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 to avoid spontaneous ignition of the oil vapour (if applicable) 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.
