(50 ft) hose. Screw the assembly onto the outlet
nipple. Don’t use thread sealant and don’t install
the spray tip yet!
3. Two gun hookup. Unscrew the cap from the 1/4
npsm(m) secondary hose outlet. Connect a hose
and gun to the outlet. Use a 1/4 in. ID, 15.1 m (50
ft) long (minimum) main hose. For more flexible
gun movement, install a 3/16 in. ID, 0.9 m (3 ft)
hose between the main hose and the gun.
CAUTION
To avoid damaging the pressure control, which may
result in poor equipment performance and component damage, follow these precautions:
1. Always use grounded, flexible spray hose at
least 50 ft. (15 m) long.
2. Never use a wire braid hose as it is too rigid to act
as a pulsation dampener.
3. Never install any shutoff device between the filter
and the main hose. See Fig. 2.
4. Always use the main filter outlet for one gun operation. Never plug this outlet.
WARNING
FIRE AND EXPLOSION HAZARD
Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Read the warning section FIRE OR EXPLOSION HAZARD on
page 2 for more detailed grounding
instructions.

WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
follow the illustrated Pressure Relief
Procedure warning on page 12 when-
ever you are instructed to relieve pressure.
NOTE: Flush the sprayer if this is a first-time startup.
See page 11.
NOTE: See Fig. 4 except where noted.
1. Put the suction tube into the paint container .
2. Turn the pressure adjusting knob fully coun-
terclockwise to zero pressure.

c. Release the trigger. Engage the gun safety latch.
5. Check all fluid connections for leaks . Relieve
the fluid pressure before tightening connections.
6. Install the spray tip and tip guard. Engage the
gun safety latch. See Fig. 3. Install the spray tip
according to the instructions supplied with it.
7. Adjust the spray pattern.
a. Increase the pressure just until spray from the
gun is completely atomized. Use the lowest
pressure needed to get the desired results. This
reduces overspray and fogging, decreases tip
wear and extends the life of the sprayer.
b. If more coverage is needed, use a larger tip
rather than increasing the pressure.
c. Test the spray pattern. T o adjust the pattern,
engage the gun safety latch, loosen the retaining
nut. Position the tip guard horizontally for a horizontal pattern or vertically for a vertical pattern.
Then tighten the retaining nut.

DO NOT drop the gear cluster (51) when removing
the drive housing (67). The gear cluster may stay engaged in the motor front end bell or the drive housing.
DO NOT lose the thrust balls (9) located at each end
of the gear cluster (51) or drop them between gears.
The balls, which are heavily covered with grease,
usually stay in the shaft recesses, but could be dislodged. If caught between gears and not removed,
the balls will seriously damage the drive housing. If
the balls are not in place, the bearings will wear prematurely.
14. While supporting the motor (73) to keep the
sprayer from tipping, remove the four motor
mounting screws (8). Lift off the motor.
15. Install the new motor (73).
16. Liberally apply bearing grease to the gear cluster
(51). The gear area should have approximately 4
total ounces of grease, Grease is supplied with
the drive housing replacement kit. Be sure the
thrust balls (9) are in place.
7. Loosen the connector nut on the connector elbow
(31) at the motor and pull the conduit (1) away
from the motor. Pull the leads through the conduit,
one at a time.
8. Unscrew the connector elbow (31) from the
motor.
9. Pull the wires through the elbow, one at a time.
10. Remove the front cover (49).
11. Remove the two drive housing screws (26).
17. Place the bronze-colored washer (67b) and then
the silver-colored washer (67a) on the shaft protruding from the big gear in the drive housing (67).
18. Align the gears and push the drive housing (67)
straight onto the front of the motor (73) and locating pins.
19. Continue reassembling the sprayer. Use a turning
motion on the conduit (1) when feeding wires
through it. Install the conduit seal (29) around the
wires in the conduit elbow (318) at the pressure
control to keep contaminants from entering the
motor conduit. See the Detail in Fig. 22.

Reassembling the Pump
NOTE: Alternate leather and plastic packings as shown
in Fig. 27. The lips of the throat “V” packings
must face down. The lips of the piston “V” packings must face up. The lips of the U–cup seal
(203*) face down. Incorrect installation damages
the packings and results in pump leaking.
NOTE: Soak leather packings in oil before using them.
1. Check the outside of the piston rod (224) and the
inside of the sleeve (218) for scoring or scratches.
If these parts are damaged, new packings will not
seal properly. Replace these parts if needed.
2. Stack the backup washer (214), seal (203*),
female gland (215*), alternate packings
(212*,206*), and then male gland (210*) onto the
piston valve (222). See Fig. 25.

REMOVING AND INSTALLING PUMP
Remove the pump
1. Flush the pump. Relieve pressure. Stop the pump
with the piston rod (224) in its lowest position or
carefully rotate the blades of the fan with a screwdriver to lower the rod.
2. While holding the pump intake valve (223) steady
with a wrench, unscrew the suction tube (71).
3. Disconnect the hose (70).
4. Push the retaining spring (42) up. Push out the pin
(43).
5. Loosen the locknut (47) and unscrew the pump
from the bearing housing (69).
69
(
Fig. 31).
3. Push the retaining spring (42) into the groove all
the way around the connecting rod.
4. Tighten the locknut (47) very tight–about 70 ft-lb
(97 N.m)–with a 2 in. open–end wrench and a light
hammer.
WARNING
Be sure the retaining spring (42) is firmly in the
groove of the connecting rod, all the way around, to
prevent it from working loose due to vibration. Refer
to Fig. 32.
If the pin works loose, parts could break off due to the
force of the pumping action. These parts could be
projected through the air and result in serious bodily
injury, sprayer damage or property damage.
CAUTION
If the locknut (47) loosens during operation, the
threads of the bearing housing (69) will be damaged.
Be sure to tighten the locknut firmly.
