Grounding
To ground the pump (FIG. 2):
1. Remove the ground screw (Z) located on the back
of the pump base.
2. Insert the ground screw (Z) through the eye of the
ring terminal (W) located at the end of the ground
wire (Y).
3. Fasten the ground screw (Z) back onto the back of
the pump and tighten the screw securely.
4. Connect the other end of the ground wire (Y) to a
true earth ground.
Mounting
Install the pump in a location that will adequately sup-
port the weight of the pump when it is filled with lubri-
cant and also provides easy operator access to the
pump air controls. The pump must be mounted in a ver-
tical position with the reservoir up. See Technical Data,
page 29 for pump weight information and the Dimen-
sions, page 28.
Low Level Models Only
DIN Connector
Connection o s made to PINS 1 and 3 of the DIN Field
Wire-able Connector. See FIG. 3.
Grounding is necessary when voltages above 30
VAC or 42 VDC are used for the low level switch or an
air valve is attached to the pump. Improper ground-
ing can cause electric shock. Grounding reduces the
risk of electric shock by providing an escape wire for
the electric current in the event of malfunction or
breakdown.
FIG. 2
Mount the pump securely so that it cannot move
around during operation. Failure to do so could result
in injury or equipment damage.

Air and Fluid Line Accessories
Refer to FIG. 1, page 6, for the following instruction
Install the air line accessories in the order shown in FIG.
1, page 6.
Bleed-type master air valve (F): required in your sys-
tem to relieve air trapped between it and the pump.
Air line filter (B1): removes harmful dirt and moisture
from compressed air supply.
Pump air regulator (B2): to control pump speed and
outlet pressure. Locate it close to the pump.
1. Install a bleed-type master air valve (F) to relieve air
trapped between it and the pump. Install the valve
in a location that is easily accessible from the pump
and located downstream of the air regulator.
2. Install an air line filter (B1) to remove harmful dirt
and contaminants from the compressed air supply.
3. Install the air regulator (B2) to control pressure.
4. Install an air line lubricator (B3) to lubricate the air
cylinder.
5. Install the (3-way) air solenoid valve (C) for control
of the pump forward and return strokes.
To use the air regulator reading to determine the fluid
output pressure, multiply the ratio of the pump (29:1)
by the air pressure shown on the regulator gauge or
see Table 1: Lubricant Output - PSI or Table 2: Lubri-
cant Output - MPa (bar), provided on page 13.
Limit the air to the pump so that no air line or fluid line
component or accessory is over pressurized.
Air Supply Lines (U)
1. Install two air supply lines (U) between the air sole-
noid outlets (C) and the pump (D) as shown in the
Typical Installation, page 6.
2. Install an air supply line (U) between the air solenoid
valve inlet (C) and the Filter/Regulator/Lubricator
Assembly (B) as shown in the Typical Installation,
page 6.
Fill Reservoir
1. Remove the grease cap (43) (FIG. 4) from the fill port
to access the fill stud (42).
2. Connect the quick connect fitting on the fill pump
to the fill port (42).
Trapped air can cause the pump to cycle unexpect-
edly which could result in serious injury from moving
parts or splashing.
NOTICE
Do not mount the air accessories directly on the
solenoid valve air inlet. The air inlet and fittings are
not strong enough to support the accessories and
may break. Provide a bracket on which to mount the
accessories.
The maximum working pressure of each
component in the system may not be the same.
To reduce the risk of over-pressurizing any part of
your system, know the maximum working
pressure rating of each component and its
connected components. Never exceed the
maximum working pressure of the lowest rated
components connected to a particular pump.
FIG. 4
Over-pressurization can result in equipment
rupture and serious injury. Fill slowly to avoid over
pressurizing the reservoir.

3. Slowly dispense grease from the fill pump into the
reservoir until the grease in the reservoir lifts the fol-
lower plate (22) above the reservoir weep hole (wh),
grease comes out of the weep hole (wh) and expels
the air inside the reservoir (FIG. 5).
4. Disconnect the fill pump from the fill stud (42) (FIG.
4, page 8).
5. Secure grease cap (43) over the fill stud (42) (FIG. 4,
page 8).
Priming
Refer to FIG. 1, page 6, for the following instruction
NOTE:
• Prime the pump before connecting the outlet to
supply line (G).
• Before priming the pump, the reservoir must be
filled with lubricant (see Fill Reservoir instructions,
page 8).
Run the pump until grease (gr), free of air, comes out of
the pump outlet (E). See Operation, page 12.
• It may take up to 20 the pump strokes to prime the
pump. This will depend on the viscosity of the lubri-
cant and temperature.
• Allow 5 seconds ON time for the forward stroke and
5 seconds OFF time for the return stroke.
Supply Lines (G)
Refer to FIG. 1, page 6, for the following instruction
1. Run the pump until grease (gr), free of air, comes
out of the pump outlet (E). Connect the supply line
(G) to the pump outlet (E).
2. If there are multiple pumps on the air line, close the
air regulators and bleed-type master air valves to all
but one the pumps. If there is only one pump, open
its air regulator and bleed-type master air valve.
3. Open the master air valve from the compressor.
4. Set the air pressure to each pump at the lowest
pressure needed to get the desired results. See
Recommended Pressure provided in Table 1:
Lubricant Output and Pressure - US or Table 2:
Lubricant Output and Pressure - Metric provided
on page 13.
Feeder Lines (S)
Fill each feeder line (S) with lubricant prior to connect-
ing lines to the injector outlet.
Injectors
1. Check each injector for proper operation. The injec-
tor stem should move when lubricant is discharged.
2. Adjust the injector output if needed to ensure that
the output volume discharged is sufficient.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Close the bleed-type master air valve (F, page 6)
(required in the system).
2. Relieve pressure in system using two wrenches
working in opposite directions on the pump outlet
(E) and lubrication line fitting (G) to slowly loosen
the fitting until it is loose and no more lubricant or
air is leaking out of the fitting (FIG. 6).
Air Lock Procedure
The reference letters used in the following instructions
refer to the Typical Installation FIG. 1 on page 6.
An air lock occurs when a bubble or pocket of air pre-
vents the normal flow of the lubricant.
If there is an air lock:
1. Refill the reservoir to the full level (page 8).
2. Relieve pressure. See Pressure Relief Procedure,
page 10.
3. Disconnect the lubricant supply line (G) from the
pump outlet (E) (FIG. 7).
4. Open the bleed-type master air valve (F, page 6).
5. Run the pump a few strokes until grease, free of air,
comes out of the pump outlet (E) (FIG. 7).
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.
