1.5 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.
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 dryer 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. Never use damaging contaminants. (e.g. dust, fibres, fine sand) for cleaning parts.
11. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts
and exposed openings with a clean cloth, paper or tape.
12. Never weld on, or in any way modify, pressure vessels.
13. 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.
14. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
15. Make sure that no tools, loose parts or rags are left in or on the machine.
16. 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.
17. 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.
18. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering
them, e.g. when steam cleaning.
19. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork,
is in good condition. If damaged, replace it by genuine material from the manufacturer to prevent the
sound pressure level from increasing.
20. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
21. The following safety precautions are stressed when handling refrigerant:
•
Never inhale refrigerant vapours. Check that the working area is adequately ventilated; if
required, use breathing protection.
•
Always wear special gloves. In case of refrigerant contact with the skin, rinse the skin with
water. If liquid refrigerant contacts the skin through clothing, never tear off or remove the latter;
flush abundantly with fresh water over the clothing until all refrigerant is flushed away; then
seek medical first aid.
Also consult following safety precautions: Safety precautions during installation and
Safety precautions during operation.
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.
