3  Safety and Responsibility

3.1  Basic Information

The machine is manufactured to the latest engineering standards and acknowledged safety regula‐

tions. Nevertheless, dangers can arise through its operation:
■ danger to life and limb of the operator or third parties,
■ impairments to the machine and other material assets.

DANGER

Disregard of these instructions can result in serious injury.
➤ Read the service manual carefully and take notice of the contents for safe machine operation.

➤ Use this machine only if it is in a technically perfect condition and only for the purpose for which

it is intended; observe all safety measures and the instructions in the service manual.

➤ Immediately rectify (have rectified) any faults that could be detrimental to safety.

3.2  Specified Use

The machine is intended solely for generating compressed air for industrial use. Any other use is

considered incorrect. The manufacturer is not liable for any damages that may result therefrom. The

user alone is liable for any risks incurred.
➤ Keep to the specifications listed in this service manual.
➤ Operate the machine only within its performance limits and under the permitted ambient condi‐

tions.

➤ Do not use compressed air for breathing purposes unless it is specifically treated.
➤ Do not use compressed for any application that will bring it into direct contact with foodstuffs

unless it is specifically treated.

3.3  Improper use

➤ Never direct compressed air at persons or animals.
➤ Use hot cooling air for heating purposes only if there is no risk to the health of humans or animals.

If necessary, hot cooling air should be treated by suitable means.

➤ Do not allow the machine to take in toxic, acidic, flammable of explosive gases or vapours.
➤ Do not operate the machine in areas in which specific requirements with regard to explosion

protection are in force.

➤ As covered by the area of application of directive 2000/14/EC, the machine is not intended for

use in the open air.

3.4  User's responsibilities

3.4.1  Observe statutory and universally accepted regulations

These are, for example, nationally applied European directives and/or valid national legislation, safety

and accident prevention regulations.
