왘 Remove the hose (4) from the bleed valve (5) and unscrew the valve
왘 Carefully remove the O-ring and the three filter meshes below the bleed valve
왘 Push a highly flexible hose (e. g. electrical shrink tubing) deep into the revealed opening to act
as breather hose
왘 Push a very flexible hose (e.g. electronic shrinkable tubing) deep into the opening which is
now visible
왘 Slowly fill the hydraulic end via this opening with hydraulic oil up to the support surface of the
bleed valve (approx. 0.65 l hydraulic oil Mobiloil DTE 11, 1.0 l, order no. 555332)
왘 Thoroughly clean the outside of the bleed valve (5) with compressed air
왘 Fit o-ring and sieve
왘 Screw in the bleed valve (5)
왘 Attach the bleed hose (4)
왘 Unfasten the union nut on the PG threaded connector on the housing of the diaphragm
rupture warning system
왘 Unscrew the housing diaphragm rupture warning system
왘 Unscrew the diaphragm rupture sensor a few turns (see Fig. 24)
왘 Screw in the diaphragm rupture sensor until it switches
왘 Now unscrew the diaphragm rupture sensor until it closes (use continuity tester) then screw
on nut (do not mount housing yet)
왘 Reconnect liquid end on the suction and discharge sides (check seals)
왘 Switch on the pump
왘 Set desired stroke
왘 If feeding against pressure, hydraulic oil must start to flow slowly along the hose to the bleed
valve after a few minutes.
NOTICE
If hydraulic oil does not flow through the hose (4) to the bleed valve, stop the pump
immediately and contact customer service. The liquid end may otherwise be seriously
damaged.
