Air Controls
•Air motor regulator and gauge (AA): Controls and
displays air pressure supplied to the air motor (B) to
drive the displacement pump (C).
•Blowoff button (AB): Turns air on and off to push
the platen out of an empty pail. The blowoff button
is only functional when the elevator director valve
(AD) is in the UP (open) position.
•Air motor shutoff valve (AC): Turns air on and off
to the air motor. The air motor shutoff valve (AC) is
shown in the ON (open) position in FIG. 2.
•Elevator director valve (AD): Applies air to the
elevator lift cylinder (L) to raise and lower the
elevator, which raises and lowers the displacement
pump (C).The elevator director valve (AD) is shown
in the UP (open) position in FIG. 2.
Air and Fluid Hoses
Be sure all air hoses and fluid hoses are properly sized
and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have

General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures.
Accessories are available from Graco. Make certain all
accessories are adequately sized and pressure-rated to
meet the system’s requirements.
Contact your Graco distributor for assistance in
designing a system to suit your particular needs.
Location
1. Attach a lifting sling at the proper lift spots (see FIG.
1). Lift off of the pallet using a crane or a forklift.
2. Position the supply system so the air controls are
easily accessible. Ensure that there is enough
space overhead for the elevator to raise fully. (See
Dimensions, page 19)
3. Ensure that the supply system base is level in all
directions to prevent the supply system from
tipping or rolling.
Grounding
Pump: use the included ground wire and clamp
(238909). Loosen grounding lug locknut and washer.
Insert one end of supplied ground wire into slot in lug
and tighten locknut securely. Connect other end of wire
to a true earth ground. See FIG. 4.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check
electrical resistance of hoses. If total resistance to
ground exceeds 29 megohms, replace hose
immediately.
Air compressor: follow manufacturer’s
recommendations.
Dispense valve: ground through connection to a
properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the dispense valve.
NOTICE
If using a lift to move the system, always lift the sup-
ply system at the proper lift location (see FIG. 1). Do
not lift in any other way. Failure to lift at the proper
lift location can result in damage to the supply sys-
tem.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.

Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
See your pump manual for flushing instructions.
Mechanical Setup
1. Fill the displacement pump wet cup 1/3 full with
Graco Throat Seal Liquid (TSL).
2. Back-off the air motor regulator (AA) to its full
counterclockwise position and close the air motor
shutoff valve (AC). This disables the pump from
running when air is applied.
3. Place the elevator director valve (AD) in the DOWN
position. This disables the elevator from lifting
when air is applied.
4. Connect the air line from an air source to the
system air inlet. See FIG. 1. Refer to the pump
performance curves in the Check-Mate Pump
Packages Instructions-Parts manual to determine
your air supply flow requirements. Use a supply
hose capable of meeting the required flow.
NOTE: Quick disconnects restrict flow for large air
motors.
5. Connect the pump outlet fittings and fluid hose (not
supplied).
NOTE: Make sure all components are adequately sized
and pressure rated to meet the system requirements.
Overview
12 3A8595A
Overview
Basic Supply System Operating
Controls
Review the following descriptions of the air controls
before operating the equipment. See Air Controls on
page 9.
Air Motor Shutoff Valve (AC)
The air motor shutoff valve (AC) turns air on and off to
the air motor (B). When closed, the valve relieves
pressure to the air motor.
Elevator Director Valve (AD)
The elevator director valve (AD) is used to raise and
lower the elevator. Moving the director valve handle to
UP will raise the elevator, and moving the director valve
handle to DOWN will lower the elevator.
Air Motor Regulator and Gauge (AA)
Air pressure to the air motor (B) can be adjusted and
viewed using the air motor regulator (AA) and gauge.
Pull the knob cap to unlock the air motor regulator (AA)
and allow rotation, and push the knob cap back in to
lock the air motor regulator (AA) and prevent rotation.
Rotate the knob counterclockwise to decrease
pressure to the air motor and decrease flow from the
pump. Rotate the knob clockwise to increase the
pressure to the air motor and increase flow from the
pump.
Blowoff Button (AB)
The blowoff button (AB) directs air to the blowoff port
on the underside of the platen (D). When the elevator
director valve (AD) is in the UP position, pressing the
blowoff button (AB) passes air under the platen,
pushing the pail away as the platen rises and keeping
the pail in contact with the elevator base. If blowoff air
is not used when the elevator is raised, the platen will
not release from the pail. Air cannot be routed to both
the elevator lift cylinder (L) and the blowoff port at the
same time. In order to keep the platen moving upwards
and also pushing away from the pail, the blowoff button
(AB) needs to be pulsed, as explained in the Pail
Change Procedure on page 16.
Raising or lowering the elevator may result in
stuttering motion. This motion is normal, and is best
described as repeated, sudden jerky movements
followed by short pauses in movement. Keep clear of
all moving parts to prevent serious injury.
Overview
3A8595A 13
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Open the dispense valve.
2. Lock the dispense valve trigger if applicable.
3. Turn the air motor shutoff valve (AC) to the OFF
position to disable the air motor (B).
4. Turn the elevator director valve (AD) to the DOWN
position to relieve pressure in the elevator lift
cylinder (L).
5. Unlock the dispense valve trigger if applicable.
6. Hold a metal part of the dispense valve firmly to the
side of a grounded metal pail, and trigger the
dispense valve to relieve pressure.
7. Lock the dispense valve trigger if applicable.
8. Open the pump bleed valve (H). Have a container
ready to catch the drainage.
9. Leave the pump bleed valve (H) open until ready to
dispense again.
10. If you suspect the dispense valve or hose is
clogged or that pressure has not been fully relieved:
a. VERY SLOWLY loosen the valve outlet fittings
or the hose end coupling(s) to relieve pressure
gradually. Refer to the appropriate manual for
specific dispense valve instructions. See
Related Manuals on page 2.
b. Remove the valve outlet fittings or the hose end
coupling(s) completely.
c. Clear the obstruction in the dispense valve or
hose.
d. Reassemble and tighten the valve outlet fittings
or the hose end coupling(s).
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.

4. Inspect the platen (D) for dried or excess material
on the seal or bottom surface of the platen.
Remove any material buildup with a scraping tool.
Keep hands away from the pump inlet.
5. Lubricate the platen seals (D) with grease or other
lubricant compatible with the fluid you will pump.
6. Remove the pail cover and smooth the surface of
the fluid with a straightedge. To prevent air from
being trapped under the platen, scoop fluid from
the center of the pail to the sides, to make the
surface concave.
7. Unscrew the bleed stick (K) and remove it from the
platen bleed port (G).
8. Put the full pail on the elevator cart and center it
under the platen (D).
9. With hands away from the pail and the platen, push
down on the elevator director valve (AD) handle,
and lower the elevator until the platen rests on the
lip of the pail.
10. If the platen (D) is not aligned with the pail, use the
elevator director valve to raise the platen, then
return to step 8.
11. Lower elevator:
a. Turn the elevator director valve (AD) to the
DOWN position, and continue to lower the
elevator until fluid appears at the platen bleed
port (G).
Moving parts can pinch or amputate fingers. When
the pump is operating, and when raising or lowering
the elevator, keep fingers and hands away from the
priming piston/pump inlet, platen (D), and lip of the
pail.
When raising or lowering the elevator, the elevator lift
cylinder (L) is prone to sudden movements due to
varying drive and frictional forces.

This manual only covers generic instructions for starting
and adjusting the pump as part of the complete system.
See your specific pump instruction manual for model
specific instructions, care of the pump, preventative
maintenance, troubleshooting, and accessory
equipment. See Related Manuals on page 2.
1. Follow the Load Pails procedure on page 14.
2. Check the fluid level in the wet cup (E). Maintain a
fluid level of 1/3 full.
3. Verify the elevator director valve (AD) is set to
DOWN.
4. Inspect the platen seal around the perimeter of the
pail periodically for leakage. If leakage is present,
clean or replace the platen seal.

motor regulator (AA) fully counterclockwise.
6. Open the pump bleed valve (H) and place a
container under the valve.
7. Turn the air motor shutoff valve (AC) to the OPEN
position to allow the pump to start.
8. Gradually turn the air motor regulator (AA)
clockwise until the pump begins to cycle.
9. Allow material to flow into the cup until there is a
smooth flow with no snapping or popping caused
by trapped air.
10. Close the air motor shutoff valve (AC) to stop the
pump.
11. Close the pump bleed valve (H).
Keep hands and fingers away from the priming
piston/pump inlet, located on the bottom of the
platen, during operation and whenever the pump is
pressurized with air. Follow the Pressure Relief
Procedure before checking, clearing, or priming the
pump.
To reduce the risk of skin injection, do not use your
hand or fingers to cover the bleed hole in the

Purge Air From the Fluid Hose and
Dispense Valve
Perform steps 12-17 only when priming new hoses, or
after replacing/maintaining wetted components
between the pump and dispense valve. These steps
describe priming from the dispense valve. If wetted
components have been cleaned or replaced, purge air
from the new/clean components, then reconnect and
prime at the dispense valve. This reduces the possibility
of pushing air through components that have already
been primed.
12. Hold a metal part of the dispense valve firmly to the
side of a grounded metal pail to collect dispensed
material.
13. Trigger the dispense valve and hold it open.
14. Open the air motor shutoff valve (AC) to start the
pump.
15. Allow material to flow into the pail until there is a
smooth flow with no snapping or popping caused
by trapped air.
NOTE: For unprimed hoses, it may take a few minutes
for material to fill the hoses and reach the dispense
head.
16. Close the dispense valve to stop material flow.
17. Make sure the elevator director valve (AD) is in the
DOWN position while the pump is operating.
Change Pails
The elevator lift cylinder (L) raises the displacement
pump (C) and platen (D). Blowoff air is used to push the
material pail off of the platen as the elevator rises.
Without blowoff air, the elevator will lift the pump,
platen, and pail. It is necessary to coordinate the rate
that the elevator lifts with the rate that the blowoff air
pushes the pail off of the platen to keep the pail in
contact with the elevator base. Keeping the pail close
to or in contact with the base of the elevator will ensure
the pail stays upright and does not tilt on the platen.
Blowoff air can only be applied when the elevator
director valve (AD) is in the UP position. A hissing
sound can usually be heard in the pail when blowoff air
is passing.
Pail Change Procedure
1. Turn the air motor shutoff valve (AC) off to stop the
pump.
2. Rotate the elevator director valve (AD) to the UP
position.
3. Once the platen (D) begins to rise, pulse the blowoff
button in one second intervals (one second ON,
one second OFF) in order to keep the platen (D)
moving while also minimizing pressure in the pail.
a. If the pail begins to raise off the cart base,
press and hold the blowoff button (AB) until the
pail contacts the cart base. Then pulse the
blowoff button (AB) as necessary to maintain
contact between the pail and the cart.
b. If the pail raises significantly above the cart
base and the pail tilts to one side on the platen,
causing blowoff air to escape from the platen
and pail, move the elevator director valve (AD)
to the DOWN position to begin lowering the
elevator until the pail makes contact and
realigns with the cart base.
Initial fluid flow from the hose or dispense valve can
splatter significantly until all air is purged. Wear
appropriate protective equipment when in the work
area and direct the fluid outlet into a container before
triggering to help prevent serious injury from
splashing fluid.
Excessive air pressure in the material pail could
cause the pail to rupture, causing serious injury. The
platen must be free to move out of the pail. Never
use pail blowoff air with a damaged pail.
Overview
3A8595A 17
4. When the platen exits the pail, release the blowoff
button and allow the elevator to rise to its full
height.
5. Remove empty pail.
6. Inspect the platen (D) and, if necessary, remove any
remaining material or material build–up. Keep
fingers away from the pump inlet.
7. Follow the procedure to Load Pails on page 14.
Shutdown and Care of the Pump
1. Set the elevator director valve (AD) to DOWN.
2. Follow the Pressure Relief Procedure on page 13.
3. Follow the pump shutdown instructions in separate
pump manual.
Material splatter may occur when blowoff pressure is
relieved between the pail lip and the perimeter of the
platen (D) as the platen exits the pail. Wear
appropriate protective equipment when in the work
area to help prevent serious injury from splashing
fluid.
