Setup
This air-powered ram extruder forces high viscosity
fluids into the intake valve of the fluid pump. Wiper
plates for use with this ram are listed on page 16.
NOTE: Always use Genuine Graco Parts and Acces-
sories, available from your Graco distributor. If you
supply your own accessories, be sure they are ade-
quately sized and pressure rated for your system.
Location
1. Position the ram so the air regulators for the pump
and the ram will be easily accessible. Ensure that
there is sufficient overhead clearance when the
ram is fully raised. Refer to Dimensions on page
19.
2. Using the holes in the ram base (28) as a guide,
drill four holes for 1/2 in. (13 mm) anchors. Refer
to Dimensions on page 19.
3. Check that the ram base is level in all directions. If
necessary, level the base using metal shims.
Secure the base to the floor using 13 mm (1/2 in.)
anchors which are long enough to prevent the ram
from tipping.
NOTE: The ram may also be mounted on portable cart
237–557. See manual 308–567 for details.
Setup of Accessories and Connecting Air
Lines
Refer to Fig. 1.
WARNING
A main air bleed valve (E) and a pump air bleed
valve (H) are required. 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 adjust-
ing or repairing the pump.
The main air bleed valve (E) shuts off and relieves
the air to the pump and ram. The ram will hold
pressure if the ram director valve (U) is in the
horizontal (neutral) position. To relieve air pressure
in the ram, close the main air bleed valve (E) and
move the director valve (U) to DOWN. The ram will
slowly drop.
The pump air bleed valve (H) relieves air trapped
between it and the pump after the air is shut off.
Trapped air can cause the pump to cycle unexpect-
edly. Locate the valve close to the pump.
The main air bleed valve (E) is required in your
system to shut off the air supply to the pump (A)
and ram (B) (see the WARNING at left). When
closed, the valve will bleed off all air in the ram and
pump, and the ram will slowly drop. Be sure the
valve is easily accessible from the pump, and is
located upstream from the air manifold (F).
The pump air bleed valve (H) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed (see the WARNING
at left). Be sure the valve is easily accessible from
the pump, and is located downstream from the air
regulator (G).
The air regulator (G) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump (A). Locate the regulator close to the pump,
but upstream from the pump air bleed valve (H).
The air manifold (F) has a swivel air inlet. To
supply air to the ram, connect a hose (EE) between
an auxiliary port of the air manifold and the ram air
inlet.
The ram air regulator (T) controls the air pressure
to the ram.
The ram director valve (U) controls the raising
and lowering of the ram.
The air release valve (V) opens and closes the
flow of air to assist raising the wiper plate (C) out of
an empty pail.
Assembling Model 222–781 Ram
NOTE: Model 222–781 Ram requires the assembly of
an extension tube which allows Model 206–450 Ram
to be used with Check-MatePumps. Refer to the
parts drawing on page 10.
1. Unscrew the cap nut (13) from the piston rod (20).
Remove the lockwasher (7). Lift the pump support
(18) off the ram.
2. Install the extension tube (105) on the piston rod
(20). Align the holes in the rod and tube, and install
the capscrew (104) through the holes. Secure with
the nut (103).
3. Install the pump support (18) on the extension tube
(105), and secure with the lockwasher (7) and cap
nut (13).
4. Install the ram as explained above.

Operation
Pressure Relief Procedure
WARNING
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:
are instructed to relieve the pressure,
stop spraying/dispensing,
check or service any of the system equipment,
or install or clean the spray tip/nozzle.
1. Lock the gun/valve trigger safety.
2. Close the pump air bleed valve (H, required in your
system).
3. Shut off the main air bleed valve (E, required in
your system). Set the ram director valve (U) to
DOWN. The ram will slowly drop.
4. Unlock the gun/valve trigger safety.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Lock the gun/valve trigger safety.
7. Open the drain valve (required in your system)
and/or the pump bleeder valve (DD), having a
container ready to catch the drainage.
8. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray tip/nozzle 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 pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
Starting and Adjusting the Ram
1. Refer to Fig. 1. Close all air regulators and air
valves.
2. Open the main air bleed valve (E) and set the ram
air regulator (T) to 2.8 bar, 0.28 MPa (40 psi). Pull
up on the director valve (U) handle so the arrow
points to UP, and let the ram rise to its full height.
3. Set a full 19 liter (5 gal.) pail of fluid on the ram
base, slide it back against the ram tube and sup-
ports, and center it under the wiper plate (C). To
prevent air from being trapped under the wiper
plate, scoop fluid from the center of the pail to the
sides, to make the surface concave.
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your
fingers. When the pump is operating and
when raising or lowering the ram, keep
your fingers and hands away from the pump intake,
wiper plate, and lip of the fluid container.
4. With your hands away from the pail and the wiper
plate, push down on the director valve (U) handle
so the arrow points to DOWN, and lower the ram
until the wiper plate rests on the lip of the pail.
Move the director valve handle to the horizontal
position (neutral).
5. Adjust the pail to be sure it is aligned with the
wiper plate, and remove the vent handle (AA) from
the wiper plate (C) to open the vent hole (BB).
6. Set the director valve (U) to DOWN and continue
to lower the ram until fluid appears at the wiper
plate vent hole (BB). Set the director valve to
neutral, reinstall the vent handle (AA) and tighten
securely. See Fig. 1.

Changing Fluid Pails
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your
fingers. When the pump is operating and
when raising or lowering the ram, keep
your fingers and hands away from the pump intake,
wiper plate, and lip of the fluid container.
To reduce risk of injury or damage to equipment,
take care when adjusting air release valve pres-
sure. Too much pressure can cause the wiper
plate to rise very quickly or burst the pail. Too little
pressure can cause the ram to lift the entire pail
from the ground.
When the pail is empty, follow this procedure to load a
new pail of material.
1. Stop the pump (A) by closing the pump air bleed
valve (H).
2. Before raising the wiper plate, locate the pushbut-
ton on the air release valve (V).
3. Raise the wiper plate out of the pail.
a. Set the ram air regulator (T) to 0.07 to 0.10
MPa (0.7–1.0 bar) (10–15 psi).
b. Set the director valve (U) to UP to raise the
wiper plate. At the same time, carefully equal-
ize pressure in the pail by operating the air
release valve (V) open and closed.
4. Raise the wiper plate until it is completely out of
the pail.
5. Remove the empty pail.
6. Inspect the wiper plate and, if necessary, remove
any remaining material or material build-up.
7. Place the full pail on the ram base.
8. Lower the ram and adjust the position of the pail
relative to the wiper plate (C), as explained under
“Starting and Adjusting the Ram” on page 4.
