Replacing the Transducer
1. Loosen and remove the four front cover screws. Remove
the front cover.
2. Stop the sprayer at the bottom of its stroke so that the
piston is in its lowest position. Turn off and unplug the
sprayer.
Before proceeding, follow the Pressure Relief
Procedure outlined previously in 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!
3. Tilt the pump back for easy access to the fluid section.
4. Using a 3/8” hex wrench, loosen and remove the two
pump block mounting screws.
5. Pull the pump block down approximately 1/2” from the
pump housing to clear the transducer.
6. Slide the pump block and piston rod forward until the
piston rod is out of the T-slot on the connecting rod.
7. Using a wrench, remove the transducer assembly from
the pump block.
8. Thread the new transducer assembly into the pump block.
Tighten securely with a wrench.
9. Reassemble the pump by reversing steps 1–6.
IMPORTANT: Make sure the transducer is aligned
properly with the hole in the pump block during
reassembly. Improper alignment may cause damage to
the transducer o-ring.
