A grooved pin A at the end of the spindle
serves as an anti-twist system for the bonnet
spindle. When mounting the compressor the
grooved pin A must be in correct alignment
with the recesses B on the compressor.
If the bonnet spindle is not in the correct
position, use the handwheel to turn it to the
correct position. The position of the grooved
pin A is offset by 90° to the position of C.
Place the compressor loosely on the bonnet
spindle, fit the wings D into the grooves C
and A into B. The compressor must be able
to be moved freely between the grooves!
