DISASSEMBLING AND REPAIRING OR REPLACING THE PUMP ASSEMBLY
1. Release the pressure from the sprayer and remove all liquid from both the pressure chamber and tank.
2. Remove hose.
3. Remove the In-tank filter from the pressure chamber.
4. Remove 2 bolts attaching the pivot lever to the pump shaft and remove piston assembly (fig. 2).
5. Remove the large clamp holding the pressure chamber and tank together (fig 1).
6. Rock the pressure chamber back and forth and push down to free it from the tank (fig 1).
7. Once freed the entire pump assembly can be removed by maneuvering it through the base frame
(fig 3a & 3b). Pump shaft may be removed to ease the disassembly of the pump.
8. The pressure chamber o-ring can also be replaced. DO NOT stretch the o-ring over the bottom flange.
Assemble the o-ring over the top of the chamber. Apply petroleum jelly to the o-ring before reinstalling
pump assembly into the tank (fig. 3b).
9. Reassemble backwards from step 7 thru 2, performing each step in reverse. Note: there is a notch/tab
combination in the pump assembly/tank to be used for alignment (fig. 4).
