Servicing/Repairing the Fluid Section
Before proceeding, follow the “Pressure Relief
Procedure” in the Operation section of this manual.
Additionally, follow all other warnings to reduce the risk
of an injection injury, injury from moving parts or electric
shock. Always unplug the sprayer before servicing!
1. Remove the safety plate (see the “Gear Box Assembly”
parts list).
2. Stop the sprayer at the top of its stroke so that the piston
is in its highest position. Turn off and/or unplug the
sprayer.
3. Remove the return tube with a wrench (see the “Siphon
Assembly” parts list).
4. Squeeze the retaining clip together (see the “Siphon
Assembly” parts list) and pull it down and out of the foot
valve (22).
5. Remove the siphon assembly by pulling it down and out
of the foot valve (22).
4. Tilt the pump back for easy access to the fluid section.
