Replacing the Transducer
1. Perform the Pressure Relief Procedure and unplug the unit.
2. Turn the pressure control knob to the “MIN PSI” position to
make sure the power supply has discharged.
3. Loosen and remove the four motor shroud screws. Remove
the motor shroud.
4. At the electronic control assembly, disconnect the black wire
coming from the transducer.
5. Pull the grommet out of the mounting plate and slide it up
the shaft of the transducer until it is clear of the mounting
plate.
6. Using a wrench, loosen and remove the transducer from
the lter housing. Carefully thread the transducer wire out
through the mounting plate.
7. Slide the grommet o of the old transducer and onto the new
transducer.
8. Thread the new transducer wire through the mounting plate
and up to the electronic control assembly.
9. Thread the new transducer into the lter housing and tighten
securely with a wrench.
NOTE: Make sure the transducer cap and inner seal on
the transducer are in place before threading the
transducer into the lter housing.
10. Push the grommet into the mounting plate.
11. Connect the transducer wire to the electronic control
assembly (refer to the electrical schematic in the Parts List
section of this manual).
12. Slide the motor shroud over the motor.
13. Secure the motor shroud with the four motor shroud screws.

Servicing the Fluid Section
Use the following procedures to service the valves and repack the
uid section.
1. Loosen and remove the four front cover screws. Remove the
front cover.
2. Position the crankshaft/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 o in short bursts until the
connecting pin is visible below the slider housing.
3. Turn o and unplug the unit.
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. Remove the return hose from the clamp on the siphon tube.
5. Unscrew the siphon tube/suction set from the inlet valve.
6. Loosen and remove the high-pressure hose from the nipple
on the back of the cylinder of the uid section.

7. Slide the retaining ring up on
the slider assembly to expose
the connecting pin.
8. 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.
9. Using a wrench, turn the jam
nut counterclockwise to loosen
it from the gear box housing.
10. Turn the uid section
counterclockwise to remove it
from the gear box housing.
11. Place the uid section cylinder
upright in a vise by clamping

13. Remove the inlet valve cage,
inlet valve ball, inlet valve seat,
and o-ring from the inlet valve.
14. Clean out any debris in the
inlet valve housing and
examine the housing and the
inlet valve seat. If the seat is
damaged, reverse or replace
the seat.
15. Using a wrench, remove the
upper seal retainer.
16. Slide the piston rod out
through the bottom of the
cylinder.
17. Inspect the piston rod for wear
and replace if necessary.
18. Remove the upper packing assembly from the top of the
cylinder.
19. Remove the adapter and lower packing assembly from the
bottom of the cylinder.
NOTE: Be careful not to scratch, score, or otherwise
damage the cylinder during removal of the
