Residual hazards
Hot surfaces
Some parts of the compressor become hot in op-
eration (up to 120 °C / 248 °F). A danger warning
sign on the compressor enclosure warns of the
danger.
Before starting any maintenance and repair work,
the compressor must be sufficiently cooled.
Personal protective equipment
We recommend the wearing of the following per-
sonal protective equipment:
Safety shoes
Safety glasses for all work with compressed air
and open enclosure
Ear defenders during test runs with an open
acoustic hood

Identification of safety
instructions
Within the operating instructions, safety instruc-
tions are used as special warnings with the follow-
ing described names and symbols.
These special warnings are intended to prevent
danger and are located close to the possible dan-
ger both in terms of space and time:
on the system close to the danger source
in the operating instructions, before a sequence
of actions / activity is described

The special warnings in the operating instructions
are structured as follows:
