General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
Accessories are available from Graco. Make certain all
accessories are adequately sized and pressure-rated
to meet your system’s requirements.
Fig. 1 is only a guide for selecting and installing sys-
tem components and accessories. Contact your Graco
distributor for assistance in designing a system to suit
your particular needs.
Hydraulic Operation
To convert the ram from air to hydraulic operation,
install Piston Kit 220501. See page 22. Contact your
Graco distributor for details.
Location
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 23.
Using the holes in the ram base as a guide, drill holes
for 1/2 in. (13 mm) anchors.
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.
Air Line Components and Accessories
Refer to Fig. 1.
WARNING
A main air bleed valve (E) and 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.
DThe main air bleed valve (E) is required in your
system to shut off the air supply to the pump and
ram (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).
DThe 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
pump air regulator (G).
DThe pump air regulator (G) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump. Locate the regulator close to the pump,
but upstream from the pump air bleed valve.
DThe air manifold (F) has a swivel air inlet. It
mounts to the ram, and provides ports for connect-
ing lines to air-powered accessories.
DAn air line filter (J) removes harmful dirt and mois-
ture from the compressed air supply. Also, install a
drain valve (W) at the bottom of each air line drop,
to drain off moisture.
DA second bleed-type air valve (K) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
DThe ram air regulator (T) controls the air pressure
to the ram.
DThe ram director valve (U) controls the raising
and lowering of the ram.
DThe air release valve (V) opens and closes the
flow of air to assist raising the wiper plate (C) out of
an empty drum.
DThe check valve (CC) bleeds air from under the
wiper plate (C) to assist in priming the pump.

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:
Dare instructed to relieve the pressure,
Dstop spraying/dispensing,
Dcheck or service any of the system equipment,
Dor 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. 9. 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 (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 drum of fluid on the ram base, slide it
back against the tube stop, and center it under the
wiper plate (C). Use the drum clamps (17) to
center, hold, and properly align the drum with the
ram. Then remove the drum cover and smooth the
surface of the fluid with a straightedge.
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 drum.
NOTE: Do not use drums that have side bungs or
large dents with this ram. Rough bung openings or
large dents will damage the wipers or stop the wiper
plate, resulting in a runaway pump.
4. Push down on the director valve handle so the
arrow points to DOWN, and lower the ram until the
wiper plate is just ready to enter the drum, then set
the valve to neutral. Reposition the drum as neces-
sary so the wipers will not hit the drum lip, then
open the check valve (CC) on the wiper plate.
5. Set the director valve to DOWN and continue to
lower the ram until fluid appears at the check
valve (CC). Set the director valve to neutral and
close the check valve.

10 306934
Operation
Starting and Adjusting the Pump
1. Be sure the pump air regulator (G) is closed. Then
set the ram air regulator (T) to about 3.5 bar (50
psi). Set the director valve (U) to DOWN.
See Fig. 9.
2. Start the pump as explained in the separate pump
instruction manual.
3. Keep the director valve (U) set to DOWN while the
pump is operating.
NOTE: Increase air pressure to the ram if the pump
does not prime properly with heavier fluids. If fluid is
forced out around the top wiper, ram pressure is too
high and the air pressure should be decreased.
