 Reassemble the seal assemblies and the pump head
 Lightly grease the supporting surfaces of the crank section/seal assembly.
 Insert the complete seal assembly with the piston (20) in the pump housing. Ensure that the O-rings (60) are
not pressed out of the grooves and damaged. Ensure that the threaded bores in the casing (10) (for the hex.
skt. head screws (90) from pump head) are correctly in position.
 (Ref. to fig.: Loosen the piston) Place the circlips (480) over the piston rods to be fixed later.
 Press the piston (20) down on the piston rod and slide the peg of the piston in the piston rod.
 Assemble the parts of the pump head as described under point pump head.
 (Ref. fig: Loosen the piston) Press the clamp halves (470) on piston and piston rod.
 Hold the clamp halves with one hand and install the circlip (480) with the other hand by using circlip pliers.
Ensure that the circlip seats correctly in the groove.
 Reassemble all lines and add-on pieces.

Test procedure
 Spray the piston with Optimol F + D. Regularly spraying of the piston with Optimol F + D prevents deposits and
extends the standing time!
 Start the pump and let it run for 5 to 10 minutes. Ensure that there are no excessive sounds or vibrations and
no excessive leakage.
 If the test procedure was successful, stop the pump and replace the cover plates.
