INSTRUCTIONS
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
This equipment is for professional use only.
Read all instruction manuals, tags, and labels before operating the equipment.
Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco
distributor.
Do not alter or modify this equipment. Use only genuine Graco parts and accessories.
Check equipment daily. Repair or replace worn or damaged parts immediately.
Do not exceed the maximum working pressure stated on the equipment or in the Technical Data
for your equipment. Do not exceed the maximum working pressure of the lowest rated component
in your system.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.
Wear hearing protection when operating this equipment.
Comply with all applicable local, state, and national fire, electrical, and safety regulations.
MOVING PARTS HAZARD
Moving parts, such as the air motor piston and elevator, can pinch or amputate your fingers.
Keep clear of all moving parts when starting or operating the pump.
Keep hands and fingers away from the elevator, pump support, drum cover, and the lip of the drum
during operation and whenever the pump or elevator is charged with air.
Before servicing the equipment, relieve the air pressure to the elevator and follow the Pressure
Relief Procedure in your separate pump manual to prevent the equipment from starting unexpect-
edly.

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.
