Installation
NOTES:
Object being sprayed: Follow your local code.
D Reference numbers and letters in parentheses in
the text refer to the callouts in the figures and the
parts drawing.
Fluid supply container: Follow your local code.
Solvent pails used when flushing: Follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the pail
on a nonconductive surface, such as paper or card-
board, which interrupts the grounding continuity.
D Accessories are available from your Graco repre-
sentative. If you supply your own accessories, be
sure they are adequately sized and pressure-rated
to meet the system’s requirements.
Grounding
To maintain proper grounding continuity when flushing
or relieving pressure, always hold the metal part of the
spray gun firmly to the side of a grounded metal pail,
then trigger the gun.
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, the pump, mount-
ing cover, and all electrically conductive objects or
devices in the spray area must be properly grounded.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment.
Positioning the Unit
D Select a convenient location for the unit. The air
valves for the pump (37), agitator (5), and elevator
(3) must be fully accessible.
For a ground wire and clamp, order
Part No. 237569.
D The elevator needs 9 ft (2.8 m) of overhead clear-
ance. Bolt the elevator to the floor as shown in the
elevator instruction manual 306287.
Pump: Connect one end of a 12 ga (1.5 mm@) mini-
mum ground wire (A) to the ground connector (B) on
the pump. See Fig. 1. Connect the other end of the
wire to a true earth ground.
System Accessories
Agitator and drum cover: Connect one end of ground
wire (A) to ground connector (B) on rim of drum cover.
See Fig. 1. Connect other end of ground wire to true
earth ground.
WARNING
A bleed-type master air valve (A) and a fluid drain
valve (M) are required in your system. These
accessories help reduce the risk of serious injury,
including fluid injection and splashing of fluid in the
eyes or on the skin, and injury from moving parts if
you are adjusting or repairing the pump or agitator.
B
A
The bleed-type master air valve relieves air
trapped between this valve and the pump after the
air is shut off. Trapped air can cause the pump to
cycle unexpectedly. Locate the valve close to the
pump. Order Part No. 107141.
Fig. 1
Air and fluid hoses: Use only electrically conductive
hoses with 500 ft (150 m) maximum combined hose
length to ensure grounding continuity.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Order Part No. 210658.
Air compressor: Follow manufacturer’s recommenda-
tions.

nated by the oil, flush it out with a compatible solvent.
Pressure Relief Procedure
WARNING
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you
To flush the pump, do the following procedure:
1. Relieve the pressure.
2. Remove the spray tip from the gun.
D Are instructed to relieve the pressure
D Stop spraying
3. Hold a metal part of the gun firmly to the side of a
grounded metal pail.
D Check or service any of the system equipment
D Install or clean the spray tips
4. Start the pump. Always use the lowest possible
fluid pressure when flushing.
1. Lock the gun trigger safety.
5. Trigger the gun.
6. Flush the system until clear solvent flows from the
gun.
2. Shut off the air supply to the pump.
3. Close the bleed-type master air valve (required in
your system).
7. Relieve the pressure.
4. Unlock the gun trigger safety.
CAUTION
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
Never leave water or water-based fluid in the pump
overnight. First, flush with water or a compatible
solvent, then with mineral spirits. Relieve the
pressure, but leave the mineral spirits in the pump
to protect the parts from corrosion.
6. Lock the gun trigger safety.
7. Open the drain valve (required in your system),
and have a container ready to catch the drainage.
Adjusting the Unit
8. Leave the drain valve open until you are ready to
spray again.
You must adjust the elevator to ensure that the cover
is supported by the drum.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
the pressure gradually. Then loosen it completely.
Then clear the tip or hose.
CAUTION
Shortened or recycled drums may cause the pump
or agitator to bottom out in the drum, causing
damage. Contact your fluid supplier to order a
standard size drum.
Flushing the Pump
WARNING
NOTE: The 100-mesh intake screen (9) should be
replaced by the coarser 50-mesh screen when using
large-orifice spray tips.
FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
AND EXPLOSION HAZARD on page
5. Be sure the entire system and flush-
ing pails are properly grounded. Refer
to Grounding on page 6.
1. Connect the air supply. Raise the elevator by
pulling out the knob of the elevator’s push/pull air
valve.
2. Place a drum of fluid under the cover, against the
elevator base.
Flush the pump before first use. The pump is
tested with lightweight oil, which is left in to protect the
8

Operation/Maintenance
3. Push in on the air valve knob to lower the elevator,
CAUTION
so the cover (A) rests on the top lip of the drum.
The support clamp (K) recesses must be tight
against the elevator riser tube. The pump intake
valve feet (B) must contact and support the perfo-
rated plate (9) as shown in Fig. 2.
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If
your pump is running too fast, stop it immediately
and check the fluid supply. If the container is
empty and air has been pumped into the lines, refill
the container and prime the pump and the lines, or
flush and leave it filled with a compatible solvent.
Eliminate all air from the fluid system.
4. Raise the elevator 1/4” (6.4 mm), then tighten the
support clamp screws. This ensures that the
cover rests on the drum lip when the elevator is in
the lowered position.
5. Adjust the restrictor valve screw to control the
speed of raising and lowering the unit. Turn the
restrictor screw clockwise to decrease the air
pressure and counterclockwise to increase air
pressure to the elevator. Lock the screw’s position
with the locknut when the adjustment is completed.
9. With the pump and lines primed, and with ade-
quate air pressure and volume supplied, the pump
will start and stop as you open and close the gun.
In a circulating system, the pump will speed up or
slow down on demand, until the air supply is shut
off.
6. Unscrew the filter bowl and remove the filter
screen. Replace the bowl. Flush the unit until
clear solvent comes from the gun, then reinstall
the filter screen.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause compo-
nent rupture and serious injury, never
exceed the specified Maximum Incoming Air Pres-
sure to the pump. (see Technical Data on
page 13.)
7. Before operation, ensure that all fasteners and
tube connections are tightened securely.
Starting and Adjusting the Pump
1. Lower the pump into the fluid supply drum.
2. Close the air regulator (F).
10. Use the air regulator (F) to control pump speed
and fluid pressure. Always use the lowest air
pressure necessary to get the desired results.
Higher pressures cause premature tip and pump
wear.
3. Open the pump’s bleed-type master air valve (E).
4. Hold a metal part of the gun (S) firmly to the side
of a grounded metal pail and hold the trigger open.
5. Slowly open the regulator until the pump starts.
Shutdown and Care of the Pump
6. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
7. Release the gun trigger and lock the trigger safety.
The pump should stall against pressure.
8. If the pump fails to prime properly, open the drain
valve (M). Use the drain valve as a priming valve
until the fluid flows from the valve. Close the
valve.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the ex-
posed displacement rod and damaging the throat
packings. Relieve the pressure.
NOTE: When changing fluid containers with the hose
and gun already primed, open the drain valve (M) to
help prime the pump and vent air before it enters the
hose. Close the drain valve when all air is eliminated.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing on page 8.
