• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
ELECTRIC SHOCK HAZARD
Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before servicing
equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and

ponent Identification page 4.
• Mount panel in a dry location near the bearing that
is being serviced.
• Line length from the air/oil mixing blocks (K) to the
spindle ranges from 2 to 50 feet (0.61 m to 15.24
m).
• Mount panel using 3/8 inch (0.375 mm) diameter
bolts. Panel mounting dimensions are provided in
the Technical Data section of this manual, page 13.
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.

Setup
1. Set the desired Pause (off) and Work (on) Times for
your model using the 3 banks of dip switches (DS-1,
DS-2, DS-3) located under the electrical enclosure
cover on the top of the pump. (See Dip Switch Set-
tings, page 8.)
The possible time choices for both the Pause and
Work Times are shown on page 8.
NOTE:
• Pause (off) Time cannot exceed 20 minutes.
• Work (on) Time cannot exceed 20 seconds.
2. Adjust the air flow using the air flow adjustment
screw (H) located on the air/oil mixing blocks (K) by
turning the set screw counter-clockwise. When the
screw is flush with the surface of the block, the
blocks are full open.
To restrict the air flow, turn the adjustment screw
clockwise.
NOTE: Entirely removing the air flow adjustment
screw (H) will cause a loss of air pressure to the
entire lubrication system.
3. Set the pressure regulator for the air/oil mixing
blocks between 30 and 60 psi (0.20 MPa, 2.06 bar
and 0.41 MPa, 4.13 bar). Refer to Air Flow Chart,
page 6 for setting guidelines.
4. Air flow is supplied on a constant basis to the air-oil
mixing block. Adjust the air regulator to achieve the
required air pressure as follows.
a. Fill the reservoir with spindle oil.
b. Press the manual run button (B).
c. Loosen the purge plug (A) on the air/oil mixing
block assembly (K).
d. Press the manual run button (B) until oil flows
out of the port. As oil begins flowing out of the
purge port, quickly tighten the purge plug (A).
e. Press the manual run button (B) 10 additional
times (allowing approximately 5 seconds OFF
time). The pressure should build on the oil pres-
sure gauge (J) to 320 psi (2.21 MPa, 22.1 bar)
and drop to 0.0 psi (0 MPa, 0 bar).
f. If pressure is not established, repeat steps b - e.
Adding a Lubrication Point
To add a point, the air/oil mixing assembly must be
removed from the panel. An additional mixing module
and new tie rod combination can then be added.
Plugging a Lubrication Point
To plug an air/oil outlet, Graco Plug Part No. 555456
must be installed in the piston distributor port on top of
the air/oil mixing block.

Dip Switch Settings: Models With Timers
Pause (off) Time (FIG. 2 and FIG. 3)
The Pause (off) Time is set using dip switches DS3 and
DS1 to select the time to deliver the required lube vol-
ume per hour. For example: If 12 cycles per hour are
required 60 ÷ 12 = 5; set the pause time to 5 minutes.
NOTE: Do not exceed 20 minutes Pause (off) time.
Work (on) Time (FIG. 2 and FIG. 3)
The Work (on) Time is set using the DS2 dipswitches.
NOTE: A Work (on) Time of 20 seconds will normally be
sufficient.
Prelube (FIG. 2 and FIG. 3)
J1 is used to Yes or No. When set to Yes, the lube cycle
will immediately power up.
Pressure Switch (FIG. 2 and FIG. 3)
For timer models, J2 must be set to the monitored posi-
tion.

Controller Settings: Models With Timers
Pause (off) Time (FIG. 3)
Set the Pause (off) Time to between 2 minutes and 20
minutes to deliver the required lube volume per hour.
NOTE: Do not exceed 20 minutes Pause (off) time.
Monitor Time (FIG. 3)
Set the Monitor Time to 20 seconds. This will allow suffi-
cient time for the system pressure to rise, piston distrib-
utors to fire and the oil pressure switch to close.
Cycle Switch (FIG. 3)
Set Cycle Switch (oil pressure switch) transition to 1.
Pressure Switch (FIG. 3)
For timer models, J2 must be set to the monitored posi-
tion.

Operation
10 313444E
Operation
Theory of Operation
Air is constantly being applied to the air/oil blocks. After
a preset Pause (off) Time, the controller activates the
pump. The green “Power ON” LED (D) lights. System
pressure builds causing the piston distributors within the
air/oil mixing module to fire. The “No OIL” pressure
switch closes.
The output from the piston distributor is discharged to
the air/oil mixing chamber where the constant flow of air
causes a thin film of oil to flow along the delivery tube in
a constant, wave-like motion. This film is then applied in
the form of a very fine spray from a drilled orifice or noz-
zle tube to the bearing elements on a constant basis.
If the oil pressure switch closes before the expiration of
set Work Time, the pump and “Pump ON” LED (C) turns
off and the timer begins its count down to the next lube
occurrence.
If the oil pressure switch does NOT close before the
expiration of the set Work Time, a fault is registered,
causing a red “Alarm” LED (E) to light. The Fault Alarm
contacts to transfer. The “Pump ON” LED (C) and pump
turn off.
Other System Faults
NOTE: If a fault occurs, press the Manual Run/Rest but-
ton to clear the fault and restart the pump. The pump will
not start until the fault is cleared.
Startup Procedure
1. Verify the pressure regulator set point for the air/oil
mixing blocks; the bearing should be receiving air.
2. Repeatedly press the manual run button (B) (allow-
ing approximately 5 seconds of OFF time between
cycles).
3. Verify oil output from each of the air/oil mixing
blocks.
NOTE: This step also ensures that the inside of the
air/oil delivery lines are coated with oil.
4. If a Timer is used, verify the cycle time.
5. Allow the system to stabilize for 15 minutes; then
check the air/oil lines to ensure that oil has reached
the bearing.
6. Start the spindle.
