9. If warm cooling air from dryers is used in air heating systems, e.g. to warm up a working area,
take precautions against air pollution and possible contamination of the breathing air.

take precautions against air pollution and possible contamination of the breathing air.
10. Do not remove any of, or tamper with, the sound dampening material.
11. Never remove or tamper with the safety devices, guards or insulations fitted on the machine.
Every pressure 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.
12. 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.
Note:
Also consult following safety precautions: Safety precautions during operation and Safety
precautions during maintenance or repair.
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.
1.5 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 starting 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. 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 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 vapor
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.
