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 fluid section.

  5.  Slide the retaining ring up on the slider assembly to 

expose the connecting pin.

  6.  Push the connecting pin forward through the slider 

assembly and piston.  The connecting pin will fall into a 

recessed area of the gear box housing where it can be 

retrieved.

  7.  Using 3/8” a hex wrench, loosen and remove the two 

pump manifold mounting screws.

  8.  Pull the pump manifold down off of the gear box housing.

  9.  Remove the four heat sink assembly mounting screws.  

Pull back the heat sink assembly for access to the 

transducer wire.

  10.  Follow the transducer wire from the transducer to the 

motor electronic control assembly and unplug the wire 

from the electronic control assembly.

  11.  Using a wrench, remove the transducer assembly from the 

pump manifold.

  12.  Thread the new transducer assembly into the pump 

manifold.  Tighten securely with a wrench.

  13.  Plug the transducer wire into the motor electronic control 

assembly where the old transducer wire was located.

  14.  Reassemble the pump by reversing steps 1–8.

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 fluid section.  Perform the following steps before performing 

any maintenance on the fluid 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 fitting on the pump manifold.  Remove the suction 

set assembly.

  6.  Loosen and remove the high-pressure hose from the outlet 

fitting on pump manifold.

Servicing the valves

The design of the fluid section allows 

access to the inlet valve and seat 

as well as the outlet valve and seat 

without completely disassembling the 

fluid 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 3/8” 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 housing 

and seat.  If the seat is 

damaged, reverse or replace the seat.

  5.  Remove, clean, and inspect the outlet valve cage and 

outlet valve ball.  Replace if they are worn or damaged.

  6.  Reassemble the valves by reversing the steps above.
