General Information

Setup

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.

D

The 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).

Fig. 1 is only a guide for selecting and installing system 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 30. 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 31.

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.

D

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 pump air regulator (G).

D The 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.

D

The air manifold (F) has a swivel air inlet. It mounts to the ram, and provides ports for connecting lines to air-powered accessories.

D

An air line filter (J) removes harmful dirt and moisture from the compressed air supply. Also, install a drain valve (W) at the bottom of each air line drop, to drain off moisture.

D A second bleed-type air valve (K) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

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 adjusting or repairing the pump.

D

The ram air regulator (T) controls the air pressure to the ram.

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.

4

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 unexpectedly. Locate the valve close to the pump.

306934

D

The ram director valve (U) controls the raising and lowering of the ram.

D The air release valve (V) opens and closes the flow of air to assist raising the wiper plate (C) out of an empty drum.

D

The check valve (CC) bleeds air from under the wiper plate (C) to assist in priming the pump.

Operation

Starting and Adjusting the Ram 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:

D are instructed to relieve the pressure,

D stop spraying/dispensing,

D check or service any of the system equipment,

D 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.

1.

Refer to Fig. 7. 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 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 necessary 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.

Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of

Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.
