4.3.1 Alteration of hanging pump bodies
CAUTION
Damage to the device
Especially with pump head pointing down, make sure that no dust or small parts can in-
trude the pump through the ventilations slot. Nevertheless, the slot must not be covered
directly. If this is not possible, the pump must not be mounted with pump head pointing
downward.
To perform this, unscrew the three Phillips head screws of the casing cover (Figure 3, Figure 4) and remove the cover (also see the
spare parts drawing at the end of the operating instructions). The crankshaft drive and the engine flange will now be visible. The
pump housing is fixed to the engine flange and/or the intermediate flange (depending on the pump type) with four hexagon
bolts (SW8). Unscrew these completely (Figure 5). When unscrewing the last screw, hold the housing tight. Now carefully rotate
the housing on the centring of the flange by 180°, screw it tight again (Figure 6, Figure 7) and then re-install the cover (tighten-
ing torque of the hexagonal bolts 3Nm). Offsetting the installation of the pump head by 45° is not permitted!
