9. Carefully slide the spring retainer onto the piston assembly.
10. Slide the assembled piston back into the piston housing.
11. Slide the spring over the piston, positioning it flush against the spring retainer.
12. Carefully slide the pump head straight onto the alignment rods. Guide the
spring over the piston guide. Gently push the piston through the seal.
13. Hold the head firmly against the pump housing and replace the two nuts. Use
a wrench to tighten them evenly.
14. Reconnect the liquid lines to the check valve housings.
15. Reconnect the power cord and turn on the power switch.
16. Prime the pump (see Section B.13
).
Avoid all lateral motion when sliding the head onto the piston. Failure
to slide the head straight on will break the piston, as well as damage
the piston seal and back-up seal.
Évitez tout mouvement latéral lorsque vous faites coulisser la tête sur
le piston. Un coulissement non rectiligne de la tête cassera le piston
et en endommagera le joint étanche et le joint étanche de sécurité.
Vermeiden Sie Seitwärtsbewegungen, wenn Sie den Kopf auf den
Kolben schieben. Andernfalls kann der Kolben abbrechen und die
Kolbendichtung sowie die Hinterspülungsdichtung zerstört werden.
