7)Apply Petroleum jelly to the inside of the piston cylinder wall and on the collar, and reinstall the piston assembly into the piston cylinder.

8)Insert the piston at an angle with the leading edge of the

collar placed over the slot in the piston cylinder. Bolt the piston assembly to the pump shaft using the lever bolts.

9) Replace the protective dust cap. Tighten the

nut and bolt. Reinstall the pump handle. Replace the hose and ﬁrmly secure the hose clamp in place.

DISASSEMBLING AND REPAIRING THE PUMP ASSEMBLY

Only remove the pump assembly if the cartridge filter is clogged or the sprayer is leaking between the pressure chamber o-ring and tank.

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 cylinder (located inside the tank - fig. 1).

4.Remove 2 bolts attaching the pivot lever to the pump shaft and remove piston assembly (fig. 2a & 2b).

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).
