Safety during use and operation

1 To lift an air dryer, all loose or pivoting parts shall first be securely fastened.
2 Lifting acceleration and retardation shall be kept within safe limits.
3 No external force may be exerted on the air valves, e.g. by pulling on hoses or by
installing auxiliary equipment directly to a valve.
4 Close the compressor air outlet valve before connecting or disconnecting a hose.
Ascertain that a hose is fully depressurized before disconnecting it.
When blowing through a hose or air line, ensure that the open end is held securely. A
free end will whip and may cause injury.
Never play with compressed air. Never apply it to your skin or direct an air stream at
people. Never use it to clean dirt from your clothes. When using it to clean down
equipment, do so with extreme caution and use eye protection.
5 Wear ear protectors when environmental noise can reach or exceed 90 dB(A). Beware
of long-time exposure to noise.
6 Periodically check that:
– all safety equipment is in good working order,
– all hoses, cables, wiring and/or pipes are in good condition, secure and not
rubbing,
– there are no leaks,
– all fasteners are tight,
– all electrical leads are secure and in good order,
– air outlet valves and manifold, hoses, couplings, etc. are in good repair, free of
wear or abuse.

Safety during maintenance and repair

Maintenance and repair work shall only be carried out by adequately trained personnel; if
required, under supervision of someone qualified for the job.
1 Use only the correct tools for maintenance and repair work.
2 Before removing any pressurized component, effectively isolate the compressor from
all sources of pressure and relieve the entire system of pressure. Do not rely on non-
return valves (check valves) to isolate pressure systems.
3 Never weld on, or in any way modify, pressure vessels.
4 Special service tools are available for specific jobs and should be used when
recommended. The use of these tools will save time and prevent damage to parts.
