INFORMATION D’UTILISATION ET COMPOSANTS DU PULVÉRISATEUR, suite

INSTALLER LA POIGNÉE DE POMPE

Le pulvérisateur inclut toute la quincaillerie nécessaire pour installer la poignée de pompe. Installez la
poignée de pompe sur la base (A). Centrez le trou de la poignée entre la découpe au bas de la base du
réservoir (B). Poussez la pince « C » sur la poignée de la pompe en alignant le tenon sur la pince avec
le trou de la poignée (C). Glissez la rondelle sur le raccordement de pompe (côté court) (D). Glissez le
raccordement du bras de la pompe (côté court) à travers la poignée de la pompe au bas du réservoir
(D et E). Glissez une deuxième rondelle sur le raccordement et insérez la goupille à travers le trou du
raccordement (E). Placez le clapet sur le dessus de la pompe (F). Vous pouvez tourner l’assemblage
de pompe pour orienter la sortie de la pompe à la position voulue (G). Tournez la poignée vers le bas
jusqu’à ce que le clapet repose sur le dessus de la pompe (F et G). Resserrez l’écrou de retenue de la
pompe (F). Ne resserrez pas trop. Enfoncez la gaine sur l’écrou de retenue (H). Assurez-vous que
l’écrou de blocage de la pompe est serré (G).

PISTON CYLINDER DISASSEMBLY AND REBUILD

1) Insure the tank and pressure chamber contents are emptied and pressure
has been released in the pressure chamber. To release pressure in the
pressure chamber activate shut-off valve and release all pressure.

2) Disconnect linkage arm from the top of the pump assembly (see section
covering Installing The Pump Handle). (Figure 1).

3) Loosen pump locking ring and remove entire pump assembly from tank
( Figure 2).

9) At this point the piston cylinder itself and/or piston cylinder stud gaskets can
be replaced. The piston cylinder stud gaskets must be oriented correctly or
leakage may result (Figure 7).

8) To rebuild disassemble two halves of cartridge and replace seal and/or ball.
Replace cartridge (Figure 6). The seal mounts inside the larger of the two
halves of the cartridge. The seal counterbore side mounts into the grooves in
the cartridge halve. Pump performance my be affected if this is not assembled
correctly.

6) Remove check valve cartridge assembly from bottom of piston cylinder
utilizing pump handle clip (clip has flat blade incorporated into end). Place flat
blade into slot in bottom of cartridge and unscrew (Figure 4 and 5).

7) Once cartridge has been removed it can either be replaced as an assembly or
rebuilt.

5) Reach in through the tank fill opening and remove the piston cylinder.

4) Remove the three bolts/washers attaching the piston cylinder to the bottom
of the tank (Figure 3).

13) Connect linkage arm to the top of the pump assembly (see section covering
Installing the Pump Handle).

10) Reassemble piston cylinder using washers and bolts on the underside of
the base.

11) Replace pump assembly into tank and into the piston cylinder which is
mounted on the bottom of the tank (see important notes regarding gasket and felt
washer in Pump and Disassembly and Rebuild section). Be careful not to damage
the plunger seal as it seats into the piston cylinder. It is recommended that you
look through the tank fill opening while performing this to achieve better
alignment. If necessary you can also reach in and use your hand to guide the
plunger seal into the piston cylinder.

12) Position the pump outlet (hose connection) in the desired position. Tighten
the pump retaining ring onto the tank.
