A double flat A (arrows picture 2) at the
end of the actuator spindle serves as an
anti-twist system of the actuator piston.
When mounting the compressor, the double
flat A must be in correct alignment with the
recess B of the compressor back (arrows
picture 1).
If the actuator piston is not in the correct
position, it must be turned to the correct
position. The position of the double flat A is
offset by 45° to the position of C.
Place the compressor loosely on the
actuator piston, fit the recesses D into the
guides C and A into B. The compressor
must be able to be moved freely between
the guides!
