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.
3. Perform the Pressure Relief Procedure 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!
4. Tilt the sprayer back for easy access to the uid section.
5. Using 3/8” a hex wrench, loosen and remove the two
pump manifold mounting screws.
6. Pull the pump block down approximately 1/2” from the
pump housing to clear the transducer.
7. Slide the pump block and piston rod forward until the
piston rod is out of the T-slot on the slider assembly.
8. Using a wrench, remove the transducer assembly from the
pump manifold.
9. Thread the new transducer assembly into the pump
manifold. Tighten securely with a wrench.
10. Reassemble the pump by reversing steps 1–7.
IMPORTANT: Make sure the transducer is aligned properly
with the hole in the pump manifold during reassembly.
Improper alignment may cause damage to the transducer
o-ring.

Servicing the Fluid Section
Use the following procedures to service the valves and repack
the uid section. Perform the following steps before performing
any maintenance on the uid section.
1. Loosen and remove the four front cover screws. Remove
the front cover.
2. Position the slider assembly at the bottom, dead-center of
its stroke so that the connecting pin and retaining ring are
visible below the slider assembly. This is done by turning
the sprayer on and off in short bursts until the connecting
pin is visible below the slider housing.
3. Perform the Pressure Relief Procedure 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!
4. For Upright Cart units, remove the return hose from the
hose clip on the siphon tube. Unscrew the siphon tube
from the inlet valve housing.
5. For Low Boy cart units, remove the retaining ring from the
bottom of the inlet valve housing using a snap ring pliers.
Remove the return hose clamp and pull the return hose
from its tting on the pump manifold. Remove the suction
set assembly.
6. Loosen and remove the high-pressure hose from the
outlet tting on pump manifold.

Servicing the Valves
The design of the uid section allows
access to the inlet valve and seat
as well as the outlet valve and seat
without completely disassembling the
uid section. It is possible that the
valves may not seat properly because
of debris stuck in the foot valve seat
or outlet valve seat. Use the following
instructions to clean the valves and
reverse or replace the seats.
1. Using a wrench, loosen and
remove the inlet valve housing
from the pump manifold.
2. Clean out any debris in
the inlet valve housing and
examine the valve housing
and seat. If the seat is
damaged, reverse or replace
the seat.
3. Using a 5/16” hex wrench,
loosen and remove the outlet valve retainer from the
piston rod.

NOTE: Always service the
outlet valve with the
piston rod attached
to the pump. This will
prevent the piston rod
from rotating during
disassembly of the
outlet valve.
4. Clean out any debris and
examine the valve retainer
and seat. If the seat is
damaged, reverse or replace
the seat.
5. Remove, clean, and inspect the outlet valve cage, crush
washer, and outlet valve ball. Replace if they are worn or
damaged.
