Cone Check/Renewal for EVC Distribution Valve
Periodically check the distribution valves for proper sealing. Do this by
running the sprayer with clean water and open all distribution valves.
Cautiously remove the clip (A) and pull out the hose (B) for the return
line. When the housing is drained, there should be no liquid flow
through the return line.
If there is any leakage, the valve cone (E) must be changed.
1. Remove the clip (C)
2. Lift the motor housing off the valve housing.
3. Unscrew the screw (D) and replace the valve cone (E).
4. Reassemble in reverse order.

ATTENTION! Follow this procedure if you are having problems
maintaining the chosen application rate.

2. Remove 4 screws (B).
3. Replace cylinder (C) and O-ring (D).
4. Loosen the nut (E), remove and replace the cone (F).
