General Information
NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing.
NOTE: Always use Genuine Graco Parts and Accesso- ries, available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure rated for your system.
To reduce the risk of serious injury, including fluid injection, splashing in the eyes or on the skin, or injury from moving parts:
1.Always relieve air and fluid pressure in the pump before raising the elevator.
2.Keep your fingers and hands away from moving parts when raising or lowering the elevator to pre- vent pinching or amputating them including between the drum and pump mounting assembly.
3.When the pump is in the raised elevator position, do not leave it unattended. Keep air supplied to the elevator. Block the pump, drum cover or pump support bracket before working on the pump.
4.Before working on the elevator, remove the pump and relieve air pressure to the elevator.
Fixed Mount Elevator
Locate the elevator where there is at least 9 ft (2.75 m) overhead clearance. Mark and drill holes for 0.5 in. (13 mm) mounting bolts. See FIG. 2 and the dimensional drawing on page 15. Level the base (17), using shims if necessary. Secure the base to the floor using four 1/2 in. (13 mm) mounting bolts which are long enough to prevent the elevator from tipping.

Installation
Pump Support Bracket
Set an open drum against the elevator base (17). Posi- tion the bracket (40) on top of the drum so that the clamp (34) recesses are tight against the elevator riser tube (14 or 28). See FIG. 1 and FIG. 3. Raise the riser tube up about 0.25 in. (6.4 mm), install the clamps (34) and tighten securely. Attach the pump mounting brack- ets (38)

Cover Support
Place the cover in its proper position in the support ring (49) and tighten the capscrews (45). Set an open drum against the elevator base (17) and put the cover on the drum so the support clamp (44) recesses are tight against the elevator riser tube (14 or 28). Raise the tube 0.25 in. (6.4 mm), then tighten the clamp screws (42). See FIG. 4.

Operation
Operation
Starting and Adjusting the
Elevator
Moving parts can pinch or amputate your fingers. When the pump is operating and when raising or lowering the elevator, keep your fingers and hands away from the elevator, pump support, drum cover, and lip of the drum.
You must adjust the elevator to ensure that the cover is supported by the drum.
1.Close all air regulators and air valves.
2.Open the main air bleed valve. Pull up on the air control valve and let the elevator rise to its full height. Normal operation requires only a few sec- onds for air pressure to build up or exhaust, and to start raising or lowering the elevator.
3.Set a full 200 liter (55 gal.) drum against the elevator base.
4.With your hands away from the drum and the cover, push down on the air control valve and lower the elevator until the cover rests on the lip of the drum. The support clamp recesses must be tight against the elevator riser tube.
5.Raise the elevator 1/4 in. (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 low- ered position.
6.Before operation, ensure that all fasteners and tube connections are tightened securely.
NOTE: To increase or decrease the operating speed of the elevator, loosen the hex nut of the restrictor valve and turn the valve needle either in or out.
Changing Drums
Moving parts can pinch or amputate your fingers. When the pump is operating and when raising or lowering the elevator, keep your fingers and hands away from the elevator, pump support, drum cover, and lip of the drum.
NOTICE
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.
1.Stop the pump. Close the pump air bleed valve.
2.Pull up on the air control valve to raise the elevator.
3.Remove the empty drum and place the full drum against the elevator base.
4.Lower the elevator. See Starting and Adjusting the Elevator.
Service
Lubrication
Every two to six weeks, take the cap (20) off the riser tube (14 or 28) and put a few drops of light, high grade motor oil on the inside surface of the tube to lubricate the leather packing (10). See FIG. 6. When replacing the cap, torque to
NOTICE
Be careful not to dent or damage the riser tube (14 or 28). Dents may cause the elevator to bind, making operation impossible.

Service
Seals and Gaskets
To replace the leather cup packings (10), screw the bearing housing (25) out of the riser tube (14 or 28) and slide the tube up off the piston (11). See FIG. 6. Screw the piston retainer capscrew (21) out of the piston body and remove the parts. Inspect parts for wear and dam- age and replace as necessary.
NOTE: When replacing packings, install a new spreader
(5). This will increase the life of the packings.
Soak new leather packing (10) in light oil, and put lithium grease on the inside surface of the tube.
To replace the guide tube gasket (19), screw the guide tube (13 or 29) out of the elevator base (17). Take the gasket out. See FIG. 6. Be careful not to damage the outside bearing surface of the guide tube. Put a new gasket into the base. Put PTFE tape on the threads of the guide tube and screw it into the base. Torque to
