as instructed in the separate gun or tip instruc-
tion manual. If you are using the RAC IV
supplied with this sprayer, see manual 308644.
5. Adjusting the Pressure
a. Turn the pressure control knob clockwise to
increase and counterclockwise to decrease the
pressure. Tighten the knob locknut to set.
b. Always use the lowest pressure that is neces-
sary to completely atomize the fluid.
CAUTION
Operating the sprayer at a higher pressure than
necessary wastes fluid, causes early tip wear, and
shortens the sprayer life.
c. If more coverage is needed, use a larger tip
rather than increasing the pressure.
d. Check the spray pattern. The tip size and
angle determines the pattern width and flow
rate. See the separate manual received with
your gun.
6. Cleaning a Clogged Tip
WARNING
SKIN INJECTION HAZARD
To reduce the risk of a fluid injection
injury , NEVER hold your hand, body or a
rag in front of the spray tip when
cleaning or checking for a cleared tip. To reduce
the risk of a fire or explosion, always hold the gun
firmly against the side of a grounded metal waste
container when checking to see if the tip was
cleared or when using a self--clearing tip.
a. Follow the Pressure Relief Procedure
Warning on page 10.
b. Clean the front of the tip frequently during the
day to keep the fluid from building up and clogging the tip. To clean, and to clear a tip if it
clogs, refer to your separate gun instruction
manual. If you are using the RAC IV tip guard
and SwitchT ip, refer to manual 308644.
7. Shutting Off the Sprayer
a. Whenever you stop spraying, even for a short
break, follow the Pressure Relief Procedure
Warning on page 10.
b. Clean the tip and gun as recommended in your
separate gun or tip manual.
c. Flush the sprayer at the end of each work day
if using water--based fluid or if it could harden
in the sprayer over night. See FLUSHING,
page 8. Use a compatible solvent to flush,
then fill the pump and hoses with solvent such
as mineral spirits to help prevent pump corrosion. Relieve pressure!
d. For long term shutdown or storage, always fill
the sprayer with mineral spirits to prevent
pump corrosion. Relieve pressure!
8. Adjusting the Intake Valve Ball Travel.
a. The pump is set to handle medium volume,
low viscosity fluid. To adjust the pump for
higher flow or heavier viscosity fluid, disassemble the intake valve as instructed in the
appropriate pump manual listed in the parts list
and move the ball stop pin to a higher set of
holes. This increases the ball travel.
11308972
Maintenance
1. Always stop the pump at the bottom of its
stroke when you take a break and at the end of
the day. This helps keep fluid from drying on the
rod and damaging the packings.
2. Keep the displacement pump packing nut/wet
cup 1/3 full of TSL at all times. The TSL helps
protect the packings and rod.
3. Check the tightness of the packing nut daily. It
should be tight enough to stop leakage but no
tighter.
CAUTION
Proper engine and hydraulic oil level is important to
prevent costly damage to the sprayer. Check it as
often as recommended in Steps 4 and 5., below.
4. Check the hydraulic oil level weekly. The oil
must be up to the top mark on the dipstick. Use
only Graco Hydraulic Oil.
5. Check the engine oil level at least weekly. The
oil must be up to the FULL mark on the dipstick.
The engine should not use more than one ounce
of oil per hour of operation. Consult the engine
manual, supplied, for additional recommended
maintenance.
8. Change engine oil and filter every 100 hour of
use. Use 30W detergent oil.
9. To change the hydraulic oil:
a. Follow the Pressure Relief Procedure
Warning on page 10.
b. Place a waste container under the drain plug
of the hydraulic reservoir. See Fig 7. Unscrew
the plug and drain the reservoir . Reinstall the
plug before proceeding.
c. Remove the nuts and reservoir cover.
d. Remove the return line filter and install a new
filter assembly.
e. Inspect the inlet filter and replace it if needed.
f. Install the reservoir cover and nuts. Then pour
in five gallons (19 liters) of Graco Hydraulic Oil
through the intake filter. See Fig 7. Install the
fill cap.

210208 Displacement Pump
Disconnect the Displacement Pump
1. Flush the pump if possible. Stop the pump on the
down stroke.
2. Follow the Pressure Relief Procedure Warning
on page 10.
3. Reference Roof Rig Parts Drawings, page 30.
4. Remove the suction tube and fluid hose from the
displacement pump.
5. Unscrew the three tie rod locknuts (48). See appropriate sprayer parts drawing.
6. Unscrew the shouldered nut (35). Pull the
displacement pump (46) off the tie rods (47).
7. Screw the jam nut (90) up onto the connecting rod
(91).
9. Refer to separate pump manual for displacement
pump repair instructions.
Reconnecting the Displacement Pump
1. Screw the connecting rod (91) into the connecting
rod coupling (36, page 30) and replace the lower
cotter pin (89). Screw the jam nut (90) all the way
down. See appropriate sprayer parts drawing.
2. Mount the displacement pump (46) onto the tie
rods (47).
3. Screw the shouldered nut (35) onto the hydraulic
motor (29). Screw the tie rod locknuts (48) onto
the tie rods (47) and torque to 35--50 ft-lb (47--68
N.m).
4. Reattach the hoses to the displacement pump.
5. If the grounding wire was disconnected before
service, be sure to reconnect it before operating
the sprayer.
8. Remove the lower cotter pin (89) and unscrew the
connecting rod (91) from the connecting rod coupling (36, page 30).

Displacement Pump Service
237510 and 222801 Displacement Pumps
Disconnecting the Displacement Pump
1. Flush the pump, if possible. Stop the pump at the
bottom of its stroke.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
2. Relieve the pressure.
3. Reference Roof Rig Parts Drawings, pages 18
through 27.
Reconnecting the Displacement Pump
1. Make sure coupling nut (170) and coupling collars
(80) are in place on displacement rod (Ref. 29).
2. Use at least two people to hold the displacement
pump while another reconnects it to the motor (see
the preceding CAUTION). Orient the pump fluid
outlet (81) to the hydraulic inlet (76) as was noted
in step 5 under Disconnecting the Displacement
Pump. Position the displacement pump (46) on
the tie rods (47).
4. Disconnect the air or hydraulic hose and the fluid
hose. Plug all hydraulic hoses immediately, to
prevent contamination of the hydraulic system.
5. Disconnect the displacement pump (46) from the
motor (29) as follows. Note the relative position of
the pump fluid outlet (81) to the hydraulic inlet (76)
of the motor. If the motor does not require servicing, leave it attached to its mounting.
CAUTION
Use at least two people when lifting, moving, or dis-
connecting the pump. This pump is too heavy for one
person. Support the displacement pump while it is
being disconnected, to prevent it from falling and
causing injury or property damage.
If the pump is mounted on a cart, slowly tip the cart
backward until the handle rests on the ground, then
disconnect the displacement pump.
6. Using an adjustable wrench (or hammer and
punch), unscrew the coupling nut (170) from the
motor shaft ( Ref. 29). Take care not to lose or
drop the coupling collars (80).
3. Screw the nuts (48) onto the tie rods (47) and
torque to 81--89 N.m (60--66 ft-lb).
4. Screw coupling nut onto motor shaft (Ref. 29),
loosely. Hold the motor shaft flats with a wrench to
keep it from turning. Use an adjustable wrench to
tighten the coupling nut. Torque to 196--210 N.m
(145--155 ft-lb).
5. Reconnect all hoses. Reconnect the ground wire if
it was disconnected. Fill the packing nut (2) 1/3 full
of Graco Throat Seal Liquid or compatible solvent.
6. Turn on the hydraulic power supply. Open the
hydraulic return line valve first, then the supply line
valve. Run the pump slowly to ensure proper
operation.
WARNING
7. Hold the tie rod flats with a wrench to keep the
rods from turning. Unscrew the nuts (48) from the
tie rods (47). Carefully remove the displacement
pump (46) from the motor (29).
8. Refer to separate manual listed in parts list for
displacement pump service. To service the hydraulic motor, refer to the separate motor manual,
supplied.
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
7. Before returning the pump to production, relieve
the pressure and retorque the packing nut (2) to
136--149 N.m (100--110 ft-lb).
