WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames, or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury.
Ground all equipment. Refer to Grounding on page 4.
If there is any static sparking or you feel an electric shock while using this equipment, shut off the
agitator immediately. Do not use the equipment until you identify and correct the problem.
Do not use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or
fluids containing such solvents in aluminum pumps. Such use could result in a serious chemical
reaction, with the possibility of explosion.
Do not use kerosene or other flammable solvents or combustible gases to flush the unit.
Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being dispensed.
Keep the dispensing area free of debris, including solvent, rags, and gasoline.
Do not smoke in the dispensing area.
Keep a fire extinguisher in the work area.
MOVING PARTS HAZARD
Moving parts, such as the rotating blades of the agitator, can pinch or amputate your fingers or other
body parts and can cause splashing in the eyes or on the skin.
Keep clear of all moving parts when starting or operating the agitator.
Always shut off the agitator and disconnect the air line before you remove the agitator from the
drum or check or repair any part of the agitator.
HAZARDOUS VAPORS
Hazardous fluids or toxic fumes can cause serious injury or death if splashed in the eyes or on the
skin, swallowed, or inhaled. When flushing the air motor, keep your face away from the exhaust port.

Grounding
Proper grounding is an essential part of maintaining a
safe system.
With an Elevator
Mount the drum cover as described in manual 306287.
The elevator must be in the down position when you
do any work on the elevator, agitator, or drum cover
assembly. Do not go under the elevator when it is
raised. Proceed to step 1 in With or Without an
Elevator.
Without an Elevator
If your system does not have an elevator, you should
install the Handles Kit to facilitate handling the drum
cover and agitator. Two people are needed to safely lift
and move the drum cover and agitator. To order the
Handles Kit, order Part No. 237524.
Place two standard 55 U.S. gallon (45 Imperial gallon)
barrels 14 in. (approximately 36 cm) apart, and center
the drum cover on the barrels with the Graco logo
centered and facing you, as shown in Fig. 2. Proceed
to step 1 in With or Without an Elevator.
To reduce the risk of static sparking, the mounting
cover and all electrically conductive objects or devices
in the dispensing area must be properly grounded.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment.
To ground the agitator, connect one end of the
ground wire (A) to the ground connector (B) on the
agitator. See Fig.1. Connect the other end of the
ground wire to a true earth ground.
For an additional ground wire and clamp, order
Part No. 237569.

Installation
With or Without an Elevator
1. Slide the agitator shaft through the large hole in
the center of the drum cover (29).
2. Rotate the agitator so that the air motor is to the
left of the shaft, as shown in Fig. 2, which will align
the three tapped holes in the bottom of the agitator
with the three through holes in the drum cover.
3. Thread the three hex head screws (25) up through
the drum cover and into the agitator, and torque
them to 75 in-lb (8.4 N-m).
4. Assemble one pair of agitator blades (28) so that
the four through holes in the blade halves are lined
up (see Parts Drawing for blade orientation).
5. Push four cap screws (31) through the four holes
in the blades, and start the lock nuts (32) onto the
cap screws.
For in–drum heavy duty back geared agitator
1. Determine which size adaptor nut (20) is needed.
The adaptor nuts in the kit are double–sided
meaning that each adaptor nut will cover two
agitator shaft sizes. Select the size you need by
placing the adaptors onto the built in agitator shaft
in the drum. The one you should use is the smallest one that will fit. There should only be a small
amount of slop between the adaptor nut and the
shaft.
2. Thread the adaptor into the gearbox output shaft
(6) with the side you are going to use pointed
down. Tighten it down using the wrench flats.
3. Place the threaded bung adaptor (34) onto the
gearbox and align the bolt holes.
6. Slide the loose blade assembly up the shaft, and
position it approximately 13 in. (33 cm) from the
bottom of the shaft.
7. Tighten the four lock nuts (32) evenly to draw the
blades together until they are tight on the shaft.
Torque the locknuts to 50 to 55 in-lb (5.6 to 6.2
N-m). A gap will remain between the blade halves.
8. Repeat steps 4 and 5 with the second pair of
agitator blades.
9. Position the second blade assembly near the
bottom end of the shaft, but not on the bottom
plug (20).
10. Rotate the lower blade assembly so that it is
oriented 90 degrees relative to the upper blade
assembly, and torque the lock nuts (32) to 50 to 55
in-lb (5.6 to 6.2 Nm). A gap will remain between
the blade halves.
4. Thread the three bolts (28) into the gear box and
torque to 10 ft–lbs (13.5 Nm).
5. Align the adaptor nut to engage the built–in shaft in
the 55–gallon drum.
6. Slowly screw the unit onto the threads on the
center bung fitting of the 55–gallon drum.
7. Torque the unit to 45 ft–lb (61 Nm). Place the
adaptor of the torque wrench on the top of the unit
to torque.

Installing the Siphon Kit
Installation
See the Siphon Kit, Model 238250, Parts List on page
15.
1. Remove the top plug (5) and the bottom plug (20).
2. Replace the bottom plug (20) with the plain bearing
(53), and tighten the bearing with a wrench.
3. Work the PTFE o-ring (54) onto the siphon tube
retainer (51), and press it into the o-ring groove.
4. Replace the top plug (5) with the siphon tube
retainer (51). Leave the retaining nut (52) on the
siphon tube retainer, but make sure it is not tightened. Tighten the siphon tube retainer into the top
of the agitator housing with a wrench.
5. Slide the siphon tube (50) down through the retaining nut (52), siphon tube retainer (51), and agitator
shaft (6) until the siphon tube touches the bottom
of the drum. Raise the siphon tube approximately
1/4 in. (approximately 6 mm) so that it does not
touch the bottom of the drum. Hold the siphon tube
at this height with one hand, and tighten the retaining nut with the other hand (hand-tight is enough to
hold the siphon tube in place).

CAUTION
Barrel Heights Vary.
Loosen the retaining nut on the siphon tube retainer
before you raise the drum cover. If you do not loosen
the retaining nut, the siphon tube may make contact
with the bottom of the barrel when you lower the
drum cover onto a new barrel, which could damage
the siphon tube or the barrel.

Return Tube Kit 238884 (Accessory)
Return Tube Kit 238884 is available as an accessory.
The kit must be ordered separately. Refer to the sheet
packed with the kit for installation instructions.
Air Requirements
For continuous use, the 3/4 HP (550 W) agitator air
motor typically requires 3 to 4 cfm (0.09 to 0.12
m3/min) air supply.
Air Line Accessories
Attach a quick disconnect air line fitting and coupler, or
attach a ball valve for main air shut–off to the air line.
To order the 1/8” npt(m) air line fitting, order Part No.
169969. To order the coupler, order Part No. 208536.
Install an air line filter to remove harmful dirt and
moisture from the air supply. To order an air line filter,
order Part. No. 106148 (3.8” npt, 20–micron element, 5
oz. Bowl, without gauge).
CAUTION
Not lubricating the air motor will cause air motor failure.
Downstream from the filter, install an air line lubricator
for automatic air motor lubrication. Set the lubricator
feed rate at 1 drop of oil per minute for high speed or
continuous duty usage. Do not overfeed oil or exhaust
air may become contaminated. To manually lubricate
the air motor, see Lubricating the Air Motor on page
10. To order a 3/8” npt air line lubricator, order Part No.
214847.
