IG. 2).

Pump (101)

• The pump can be driven by an electric motor or by a
rotating or oscillating machine motion.

• The pump must always be installed with the reser­voir (11) in a vertical position to ensure proper oper­ation.

• Always use lockwashers with mounting bolts and
make certain that the bolts are properly torqued.

Motors and Drives

Gear Reducer

NOTICE

Gear reducer units are shipped without lubricant.
Before operating, always check lubricant level and fill
per manufacturers instructions. Operation without lubri­cant will damage the gear reducer. A table of sug­gested lubricants is provided on page 24.

Gear reducers have either a 10:1 or 60:1 reduction or an
oscillating clutch drive that can be activated by a
machine motion.

FIG. 2

Grease Reservoirs

FIG. 3

• Grease reservoirs require an external air-free sup­ply source connected to the fill stud (13).

ENTANGLEMENT HAZARD

An exposed drive shaft must be guarded to enclose
the shaft.

• A shaft guard is included if the pump is configured
with a gear reducer.

• The user must provide a guard for any other config­uration.

Low-Level Switch

Low-level switches protect the system against excessive
pressure and low lubricant levels. The switch provides
an electrical signal when the lubricant level in the reser­voir is low.

Installation Instructions

Installation Instructions

The reference letters and numbers used in the following
sections, refer to F

Components are completely assembled when you first
receive the LubeMaster Pump Package from the factory.
Reassembly instructions for these components are pro­vided in the Maintenance and Repair section of this
manual, beginning on page 17.

IG. 1.

Grounding

The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Install a 12 gauge (1.5 mm) minimum ground wire
between the LubeMaster pump package and a true
earth ground.

Pressure Relief Valves

Choosing an Installation
Location

AUTOMATIC SYSTEM ACTIVATION HAZARD

The system is equipped with an automatic timer that
activates the pump lubrication system. Unexpected
activation of the system could occur and result in
serious injury, including skin injection and amputa­tion.

Before you install or remove the lubrication pump
from the system, disconnect and isolate all power
supplies and relieve all pressure.

• Select a location that will adequately support
the weight of the pump and lubricant, as well as
all plumbing and electrical connections.

• Refer to the mounting hole layouts provided in
the Dimensions section of this manual begin­ning on page 37. No other installation configura­tion should be used.

• Use designated mounting holes and provided
configurations only.

• Use fasteners that are strong enough to support
the weight of the pump and lubricant when
securing the pump to the mounting surface.

To prevent over-pressurization, which can result in
equipment rupture and serious injury, a pressure
relief valve appropriate for the lubrication system
must be installed close to every pump outlet to allevi­ate unintended pressure rises in the system and pro­tect the pump from damage.

• Only use a pressure relief valve that is rated for no
more than the working pressure of any component
installed in the system. See Technical Data, page

35.

• Install a pressure relief valve close to every pump
outlet and before any auxiliary fitting.

8 3A2781A

Pump Installation Procedure

1. Secure with attaching hardware to installation loca­tion. Make certain all fasteners are tightened to the
proper torque.

2. Install all guards and mechanical linkages or con­nections removed at the pump drive shaft.

3. Install the reservoir.

4. Electrically reconnect the pump drive.

5. Fill system with lubricant. See Filling the Reservoir
instructions, beginning on page 9.

Setup

Filling the Reservoir

Material Cleanliness

Make sure that lubricant used to fill the system is clean.
If there is doubt about cleanliness, lubricant should be
filtered before being introduced into the system. System
life and consistent operation will both be improved by
using clean lubricant.

After filtering the lubricant, make sure the lubricant sup­ply is protected from debris.

On all pumps, the lube piston diameter is very close to
the diameter of the chamber in the pump body. Contam­inants in the lubricant could cause scoring in this area,
resulting in erratic pump operation and costly parts
replacement.

Temperature Effects

Flow characteristics of the lubricant may change if the
area the unit is used in goes through drastic tempera­ture changes. Choose a lubricant that will flow properly
at all temperatures expected in the system environment.

Overhead Supply Adapter Assemblies Only

Filling Oil Reservoirs

Oil reservoirs have a fill cap (30) and filter (31).

FIG. 4

1. Wipe the area around the fill cup to avoid contami­nation during filling.

2. Open the fill cap (30) and slowly pour oil into the
reservoir (11) through the filter screen (31).

NOTE: The filter screen (31) will remove large parti­cles which may be present in the oil.

The recommended inlet pressure is 15 psi (0.103 MPa,

1.03 bar) or less.

3. When filling is complete, close fill cap (30) and wipe
any spillage.

Filling Grease Reservoirs

OVER PRESSURIZATION HAZARD

Over pressurization can result in equipment rupture
and serious injury. Fill slowly to avoid over pressuriz­ing the reservoir.

FIG. 5

• Filling grease reservoirs requires an external,
air-free supply source be connected to the fill stud
(13).

• To avoid introducing air into the system, make sure
there is enough grease in the supply source to fill
the reservoir without being disconnected.

• Operate the supply source at a steady speed to
allow air-free filling of the reservoir. Filling the reser­voir too fast may result in air pockets.

1. Remove cover (12)

2. Connect grease supply source to fill stud (13).

3. Loosen the drain plug (E) (located on the opposite
side of the base from the fill stud (13) (F

IG. 6).

FIG. 6

4. Slowly begin to fill the reservoir, allowing air trapped
under follower to exhaust out the open drain plug.

5. When grease free of air flows from the drain, tighten
the plug (E) and continue to fill the reservoir until fol­lower is at the vent hole in reservoir tube (any
remaining air and small amount of grease will exit
drain).

6. When filling is complete, turn off the supply source
and disconnect if from the fill stud (13). Replace the
cover (12).

NOTE: A check valve in the fill stud will prevent
lubricant from being forced back out.

• The level of grease is checked by visual means.

- In reservoirs with plastic cylinders, the grease level
can be viewed through the cylinder.

10 3A2781A

7. Loosen system mainline connection at pump outlet.

8. Operate pump until lubricant free of air flows from
outlet port.

9. Tighten mainline connection at pump. Pump is now
free of air.

NOTE: If the pump will not take a prime, it may be
helpful to inject several ounces of heavy oil through
the fill stud. The pump will then prime on oil pulling
the grease behind it. If it becomes necessary to use
this method, all injected oil should be discharged at
the loosened system mainline connection along with
any air.

Setup

System Filling

After the reservoir is filled as described in Filling the
Reservoir, page 9, fill the remainder of the system by
attaching a hand pump to the system downstream from
the pump manifold block assembly and cycle the hand
pump until the system is filled.

Manifold Bleeding

Proper filling of the system will reduce the chance of air
entrapment. The pump block manifold assembly (117,
page 28) must be bled to remove air which will be
trapped inside the pump. Cycle the pump several times
until air-free lubricant is dispensed.

NOTE: Manual air bleeding procedures are necessary
in the event any system components are loosened, dis­connected or otherwise removed after their initial instal­lation.

Adjusting the Clutch Drive

The degrees of throw of the clutch lever is adjustable
from 12 to 60 degrees. Table 1 (page 12) provides the
minimum/maximum pump outputs. The actual pump
output for your installation may be computed by using
the Calculating Pump Output procedure (page 12).

Using the clutch lever diagram provided in F
mine the anticipated clutch lever throw angle.

Operation

Startup

Before attempting to operate any system, check the
following:

• Ensure the reservoir is securely fastened to the
pump and that the fill cap or grease-fill fitting is eas­ily reached.

• Check that the pump is securely fastened in place.

• Check that gear reducer has been filled with proper
lubricant.

• Check all electrical connections to any controllers,
level switches or pressure switches used on the sys­tem.

While the system is operating, periodically check
the following components:

• Check that the pump is cycling according to sched­ule.

• Visually check the unit for leaks and loose fittings.
Make sure that hoses do not become kinked and
are not rubbing on anything.

• If the reservoir is not equipped with a low-level
switch, visually check the lubricant level and refill
before all lubricant is used.

NOTE: If the reservoir is allowed to run dry, excess
air will be introduced into the system, requiring that
the system be bled.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.

• Check that all accessories plumbed into the output
manifold block assembly are secure.

• Make sure all hose or tubing connections are tight.

• Check that the reservoir is filled with lubricant. See
Filling the Reservoir, page 9.

• Check that all filling and bleeding steps have been
completed.

• Check the output of the lubricant pump. Adjust the
output as described in the Clutch Drive - Calculating
Pump Output, page 12.

• If the pump is equipped with a clutch drive, verify it
is properly adjusted as described in the Adjusting
the Clutch Drive section, page 11.

The unit is now ready to run. The pump is cycled by an
external source, such as a timer, counter, control pack­age, or customer-supplied drive. Once this external
source is engaged, the unit will cycle as programmed.

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro­cedure when you stop dispensing and before clean­ing, checking, or servicing the equipment.

1. Verify pump is stopped and disconnected from
power source.

2. Using a wrench, slowly loosen the outlet fitting (a,
F

IG. 9) connected to the pump block manifold

assembly until the fitting is loose and no more lubri­cant or air is leaking from the fitting.
