Mounting the pump head
NOTICE
The pump head cannot be mounted the wrong way, as it has fastening
bolts with different bore hole depths, i.e., one fastening bolt is longer
than all others. The bore hole with the greatest depth must therefore
be aligned with the longest bolt.

￭ Push the pump head onto the four fastening bolts (1).
￭ Tighten the four fastening screws using the hex key (6.2621.030)
alternating crosswise.
