WARNING
Beware of electric shock!
Danger of physical injuries that may have fatal consequences.
Before starting work, switch off the power supply to the electrical connection and prevent it from
being restored without due authorization.
WARNING
Pneumatic system is under high pressure.
Personal injury.
Prior to removal, vent the pressure from the (sub)system while observing the safety regulations for
electrical and pneumatic systems.
CAUTION
Use of unacceptable working substances!
Damage to equipment, total failure possible.
The oil grade must agree with the installation drawing and/or oil label. Never mix different types of
oil.
CAUTION
The use of an impact wrench to screw the sensor onto the compressor is not permitted. Knorr-
Bremse recommends using electronically controlled wrenches (torque and angle of rotation) for
installation. If any work on the compressor requires the use of any tools which could lead to strong
vibrations, the sensor must be removed first.
CAUTION
Hot surfaces!
Danger of burns close to the motor compressor set.
Allow the surfaces to cool down, and wear gloves for protection.
