Prevent polution in the air lines
Correct Incorrect
All air lines have a air connection with a closing lid.
Always close after uncoupling the air connection on
the head board.
Hang up the air lines again after uncoupling. This
prevents sand/polution in the air connections, which
can enter the EBS modulator through the compressed
air.
