General

1.2

Introduction

The compressor and its additional equipment must not be installed and com-
missioned until the operating instructions are understood.
These operating instructions can be supplemented with instructions on the 
basis of existing national regulations concerning accident prevention and envi-
ronmental protection.
In the illustrations, the compressor is shown in part without safety cladding or 
safety devices for better visualization. However, operation without these com-
ponents is prohibited!

Symbols used

In these operating instructions, important safety instructions and tips are iden-
tified by the following symbols:

WARNING!

This symbol indicates information warning of dangers to life and limb of the 
operator or other persons or dangers, which might destroy or damage the 
compressor.

WARNING: Risk of injury!

This symbol indicates information warning of possible danger to life and limb 
of the operator or other persons.

DANGER: Voltage!

This symbol indicates information warning of life threatening electrical volt-
age levels.
It indicates work which must be exclusively performed by skilled electricians.

NOTICE!

This symbol indicates information and tips concerning the economical and 
careful operation of the compressor.
