Always wear protective gloves when working on the compressor to avoid
bruising fingers or hands while opening or closing components!
WARNING!
Make sure that the compressor is installed in compliance with the installation
requirements!
Prior to starting up the compressor for the first time, check to ensure whether
the transport securing device was removed correctly and the GM-belt ten-
sioning device was activated (see chapter "3.3 Installation")!
Record the test results in the commissioning certificate.
WARNING!
Always check the rotational direction of the drive and fan motor prior to com-
missioning.
Even brief operation in the wrong direction of rotation (more than approx.
5 seconds) may cause the total destruction of the air end!
Record the test results in the commissioning certificate.
WARNING!
Ensure that the rotational direction coincides with the rotational direction
arrow on the air end.

2. Switch the compressor on and immediately off again to check the rota-
tional direction.
WARNING: Risk of injury!
Press the emergency stop switch/button, disable the mains disconnection
device and secure it with a padlock to prevent it from being switched on again
inadvertently.
