Installation

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 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.

WARNING

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 mov-

ing parts when raising or lowering the elevator

to prevent pinching or amputating them includ-

ing between the drum and pump mounting

assembly.

3. When the pump is in the raised elevator posi-

tion, 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.

Moveable Stand Mount Elevator

Locate the elevator where there is at least a 9 ft

(2.75 m) overhead clearance. Install the four

stabilizers (23) as shown in Fig. 1. Secure in place with

the setscrews (1).

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 dimen-

sional 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 or 22).

Position 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 or 22) 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.

Air Connection

Screw the restrictor valve (55) into the push-pull valve

(60) as shown in Fig. 5. Mount the valve on the wall at

a convenient height, using the mounting bracket (54).

Connect the master air supply to the valve. Screw the

elbow fitting (52) into the 1/8 npt(f) inlet of the restrictor

valve. Push one end of the copper tube (51) into the

elbow and tighten the fitting. Screw the straight fitting

(53) into the base (17 or 22) of the elevator. Push the

other end of the copper tube (51) into this fitting and

tighten the fitting.

NOTE: With the moveable stand mount elevator, the

air control valve must exhaust air to enable the eleva-

tor to lower.

Operation

Starting and Adjusting the Elevator

You must adjust the elevator to ensure that the cover

is supported by the drum.

 Close all air regulators and air valves.

 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.

 Set a full 200 liter (55 gal.) drum against the eleva-

tor base.

WARNING

MOVING PARTS HAZARD

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 eleva-

tor, pump support, drum cover, and lip of the drum.

 With your hands away from the drum and the cov-

er, 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 lowered 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

WARNING

MOVING PARTS HAZARD

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 eleva-

tor, pump support, drum cover, and lip of the drum.

CAUTION

Shortened or recycled drums may cause the pump

or agitator to bottom out in the drum, causing dam-

age. Contact your fluid supplier to order a standard

size drum.

 Stop the pump. Close the pump air bleed valve.

 Pull up on the air control valve to raise the eleva-

tor.

 Remove the empty drum and place the full drum

against the elevator base.

 Lower the elevator as explained at left.

Service

Lubrication

Every two to six weeks, take the cap (20) of f 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 20–40 ft-lb (37–54 NSm).

CAUTION

Be careful not to dent or damage the riser tube (14

or 28). Dents may cause the elevator to bind, making

operation impossible.

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 damage 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. Re-

assemble in the reverse order. Apply LoctiteR 56765

thread sealant to the internal threads of the piston

body (11) and the threads of the capscrew (21). Torque

the capscrew to 15–20 ft-lb (20–27 NSm).

To replace the guide tube gasket (19), screw the guide

tube (13 or 29) out of the elevator base (17 or 22).

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 R tape on

the threads of the guide tube and screw it into the

base. Torque to 90–130 ft-lb (122–175 NSm).

Push-Pull Valve

Remove the valve guide (71), washer (64), o-ring (66*)

and seal (67*). Pull the assembled valve parts out of

the valve body (70). See the Parts Drawing on

page 8. Disassemble parts, clean and inspect. Re-

assemble the valve, using new parts as necessary.
