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. Before removing any pressurized component, effectively isolate the machine from all sources of
pressure and relieve the entire system of pressure.
8. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions
against toxic vapours of cleaning liquids.
9. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the
parts and exposed openings with a clean cloth, paper or tape.
10. 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.
11. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
12. Make sure that no tools, loose parts or rags are left in or on the machine.
13. All regulating and safety devices shall be maintained with due care to ensure that they function
properly. They may not be put out of action.
14. Before clearing the machine for use after maintenance or overhaul, check that operating pressures,
temperatures and time settings are correct. Check that all control and shut-down devices are fitted
and that they function correctly. If removed, check that the coupling guard of the compressor drive
shaft has been reinstalled.
15. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from
entering them, e.g. when steam-cleaning.
16. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
17. The following safety precautions are stressed when handling desiccant:

Take precautions not to inhale desiccant dust.

Check that the working area is adequately ventilated; if required, use breathing
protection.

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 manufacturer.
