Mounting
1. Plan the mounting layout for easy operator access
to the pump air controls, suf ficient room to change
drums and a secure mounting platform.
2. If using a follow plate (H), remove the drum cover .
Scoop the material to the center of the drum to
make the surface concave. Place the plate on the
material. Guide the pump foot valve through the
plate.
3. Mount the pump to the drum cover or other suit -
able mounting device.
4. For ease in changing drums, install a pump eleva -
tor.
Air and Fluid Line and Accessories
Refer to Figure 1 above.
WARNING
The bleed-type master air valve (J) is required in
your system to help reduce the risk of serious inju -
ry from moving parts if you are adjusting or repair -
ing the pump. Locate the valve close to the pump,
and downstream from the air regulator . The bleed
valve relieves air trapped between it and the air
motor after the air supply is shut of f. T rapped air
can cause the air motor to cycle unexpectedly ,
causing serious injury .
CAUTION
Do not hang the air accessories directly on the air
inlet. The fittings are not strong enough to support
the accessories and may cause one or more to
break. Provide a bracket on which to mount the
accessories.
NOTE:
Install the air line accessories in the order
shown in Figure 1.
1. Install a pump runaway valve (G) to shut of f the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump which runs too fast
can be seriously damaged.
2. Install an air line lubricator (F) for automatic air
motor lubrication.
3. Install a bleed-type master air valve (J) to relieve
air trapped between the valve and the motor (see
WARNING at left). Order Part No. 107–142.
4. Install the air regulator (C) to control pump speed
and pressure.
5. Install an air line filter (E) to remove harmful dirt
and contaminants from your compressed air sup -
ply.
6. Install a second bleed-type master air valve (J)
upstream from all other accessories, to isolate the
accessories for servicing.

Installation
Grounding
Proper grounding is an essential part of maintaining a
safe system.
T o reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this equipment:
1. Pump: use a ground wire and clamp as shown in
Fig. 2.
2. Air and fluid hoses: use only electrically conductive
hoses.
3.
Air compressor: follow manufacturer ’ s recommen -
dations.
4.
Fluid supply container: according to local code.
5. T o maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
valve firmly to the side of a grounded metal pail,
then trigger the valve.
To ground the pump:
To ground the pump , loosen the grounding lug locknut
(W) and washer (X). Insert one end of a 12 ga (1.5
mm ) minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely . Connect the other
end of the wire to a true earth ground. Order Part No.

Operation
Pressure Relief Procedure
INJECTION HAZARD
The equipment stays pressurized until
pressure is manually relieved. T o reduce
the risk of serious injury from pressur -
ized fluid, accidental spray from the valve or
splashing fluid, follow this procedure whenever you:
 are instructed to relieve pressure,
 stop dispensing,
 check, clean or service any system equipment,
 install or clean dispensing devices.
WARNING
1. Close the pump air regulator and the bleed-type
master air valve (required in your system).
2. Hold a metal part of the dispensing valve firmly to
a grounded metal waste container and trigger the
valve to relieve the fluid pressure.
Startup
1. If there are multiple pumps on the air line, close
the air regulators and bleed-type master air valves
to all but one pump. If there is only one pump,
close its air regulator and bleed-type master air
valve.
2.
Open the master air valve from the compressor .
3.
For the pump which is supplied with air , open the
dispensing valve into a grounded metal waste con -
tainer
, making firm metal-to-metal contact between
the container and valve. Open the bleed-type mas -
ter air valve and open the pump air regulator
slowly , just until the pump is running. When the
pump is primed and all air has been pushed out of
the lines, close the dispense valve.
4. If you have more than one pump, repeat this pro -
cedure for each pump.
NOTE: When the pump is primed, and with suf ficient
air supplied, the pump starts when the dispensing
valve is opened and shuts of f when it is closed.
5. Set the air pressure to each pump at the lowest
pressure needed to get the desired results.
COMPONENT RUPTURE HAZARD
The maximum working pressure of each
component in the system may not be the
same. T o reduce the risk of overpressur -
izing any component in the system, be sure you
know the maximum working pressure of each com -
ponent. Never exceed the maximum working pres -
sure of the lowest rated component in the system.
Overpressurizing any component can result in rup -
ture, fire, explosion, property damage, and serious
injury.
T o determine the fluid output pressure using the air
regulator reading, multiply the ratio of the pump by
the air pressure shown on the regulator gauge. For
example:
50 (:1) ratio x 100 psi air =
5000 psi fluid output
[50 (:1) ratio x 7 bar air = 350 bar fluid output]
Limit the air to the pump so that no air line or fluid
line component or accessory is overpressurized.
WARNING
6. Never allow the pump to run dry of the material
being pumped. A dry pump will quickly accelerate
to a high speed, possibly damaging itself. If your
pump accelerates quickly , or is running too fast,
stop it immediately and check the material supply .
If the supply container is empty and air has been
pumped into the lines, prime the pump and lines
with material, or flush it and leave it filled with a
compatible solvent. Be sure to eliminate all air
from the material lines.
NOTE: A pump runaway valve (G) can be installed on
the air line to automatically shut of f the pump if it starts
to run too fast.
7. Read and follow the instructions supplied with
each component in your system.
8. T o shut of f the system, always follow the Pressure
Relief Procedure W arning , at the left.

Toubleshooting
WARNING
T o reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
Relieve pressure before you check or service any sys -
tem equipment.
WARNING
MOVING P ARTS HAZARD
Never operate the pump with the warn -
ing plate or the identification plate re -
moved. These plates protect your fin -
gers from pinching or amputation by moving parts
in the air motor .
NOTE: Check all other possible problems and solu -
tions before disassembling the pump.
