persons with the necessary training under the 
supervision of a qualified electrician, and in com-
pliance with the regulations applicable to electri-
cal equipment. 

• 

Please note that for units with combustion engine 
special safety preventions have to be observed. 

• 

Always switch the machine off when it is not in 
use.

port for climbing. 

• 

Operating and maintenance personnel must wear 
suitable working clothes. Rings and other jewel-
lery must be removed before work starts on the 
machine. Long hair must be tied up under a hair-
net or similar. 

• 

Goggles or similar eye protection must be worn 
for work with compressed air, as loose parts and 
particles of dirt can be blown into the face. 

• 

When operating the machine, wear personal ear 
protection of the right kind for the noise level 
involved. 

• 

Never aim compressed air at any person - you 
could cause injury!

TRANSPORTATION 

 

Warning

- keep away from suspended loads

 

A suspended load could crash to the ground, and 
could cause very serious injury. It is strictly forbid-
den to move or stand in the danger area underneath a 
suspended load. 
 

CAUTION! Improper lifting

 

Lifting the compressor in the wrong way can damage 
it, so only ever lift this compressor at the points 
provided. Never lift it by its cladding or by the 
compressor block. 
 

WHEN LIFTING AND TRANSPORTING THE 
COMPRESSOR: 

• 

Let the air off from the machine 

• 

Undo the connections 

• 

Secure loose or moving parts 

• 

Adhere to local safety regulations 

• 

Only ever use suitable lifting gear with sufficient 
lifting capacity. 

 

SETTING UP AND CONNECTING  

SETTING UP 

Set the compressor up in a cool, dry place. 

 

To dampen noise and vibration, we recommend the 
use of damping rubber elements or oscillating metal 
parts. 

 

PLEASE PAY PARTICULAR ATTENTION TO 
THE FOLLOWING: 

• 

The air receiver should be easily accessible from 
all sides. 

• 

The distance between the ventilation wheel on the 
machine and the nearest wall must never be less 
than 400 mm. 

• 

The surface on which the compressor stands must 
be level and capable of bearing the weight. 

• 

The ambient temperature must lie b5°C 
and +40°C. 

• 

The room in which the compressor stands must be 
adequately ventilated. 

• 

The suction air must be clean. Caustic, combusti-
ble or poisonous gases must not be suctioned. 

• 

The filter insert of the air suction filter has a 
separation degree of 10 

µ

m. All particles of more 

than 10

µ

m are filtered out of the suction air. 

Smaller particles can pass through the filter. If the 
compressor is operated in a place where fine dusts 
exisit (cement plant ,gravel plant or building sites 
etc.) an optional filter insert with a separation 
degree of 3 

µ

m must be used.
