Installation  
Any pails used when flushing: Use only metal,  
Mounting the Pump  
grounded pails when flushing. Make firm  
metal-to-metal contact between a metal part of the  
dispensing valve and the pail. Use the lowest possi-  
ble pressure.  
Mount the pump securely so that it cannot move dur-  
ing operation. Failure to do so could result in per-  
sonal injury or equipment damage.  
To maintain grounding continuity when flushing or reliev-  
ing pressure, always hold a metal part of the valve firmly  
to the side of a grounded metal pail, then trigger the  
valve.  
Select a location that allows the operator easy  
access to the pump and air controls, sufficient room  
to change supply containers, and a secure  
mounting platform.  
To ground the pump, remove the ground screw (Z) and  
insert through the eye of the ring terminal at end of  
ground wire, (Y). Fasten the ground screw back onto the  
pump and tighten securely. Connect the other end of the  
ground wire to a true earth ground. See FIG. 2. To order  
a ground wire and clamp order Part No. 222011.  
If you are mounting the pump directly on the supply  
container, be sure it is positioned so the pump’s  
intake tube is no more than 1 in. (25 mm) from the  
bottom of the container. Mount the pump to the  
cover or other suitable mounting device.  
To prevent damage to the pump, remove sedi-  
ment from the bottom of the container before  
installing a pump in an existing container.

Grounding  
Proper grounding is essential to maintaining a safe  
system.  
TI1052  
FIG. 2  
To reduce the risk of static sparking, ground the pump.  
Check local electrical codes for detailed grounding  
instructions for your area and equipment type. Be sure  
the following equipment is properly grounded:  
Pump: See FIG. 2.  
Air and fluid hoses: Use only electrically conductive  
hoses.  
Air compressor: Follow manufacturer’s  
recommendations.  
Dispensing valve: Obtain grounding through con-  
nection to a properly grounded fluid hose and pump.  
Fluid supply container: Follow your local code.  
Object being lubricated: Follow your local code.

Operation  
Operation  
See FIG. 1 to identify references shown in parentheses,  
i.e., (A).  
3. Open the pump air regulator (C) slowly, just until the  
pump is running. When the pump is primed and all  
air has been pushed out of the lines, close the dis-  
pensing valve (H).  
NOTE: When the pump is primed, and with sufficient air  
supplied, the pump starts when the dispensing valve (H)  
is opened, and shuts off when it is closed.  
This equipment stays pressurized until pressure is  
manually relieved. Read PRESSURIZED EQUIP-  
MENT HAZARD warnings on page 2.  
4. Adjust the air regulator (C) until you get sufficient  
flow from dispensing valve (H). Always run the  
pump at the lowest pressure necessary to get the  
desired results. Do not exceed the maximum work-  
ing pressure of any component in the system.  
Maximum working pressure of all components in the  
system may not be the same. To reduce risk of over-  
pressurizing any component, be sure you know the  
maximum working pressure of each component.  
Never exceed the maximum working pressure of the  
lowest rated component in the system. Overpressur-  
izing any component can result in rupture, fire, explo-  
sion, property damage, and serious injury.  
CAUTION  
Never allow the pump to run dry of the fluid being  
pumped. A dry pump will quickly accelerate to a high  
speed, possibly causing pump damage. It may also get  
very hot.  
To 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:  
5. If your pump accelerates quickly or is running too  
fast, stop it immediately and check the fluid supply. If  
the supply container is empty and air has been  
pumped into the lines, prime the pump and lines  
with fluid, or flush it and leave it filled with a compat-  
ible solvent. Be sure to eliminate all air from the fluid  
lines.  
3:1 ratio x 100 psi air = 300 psi fluid output  
Limit the air pressure to the pump so that no air line  
or fluid line component is overpressurized.  
Pressure Relief Procedure  
1. Close the pump air regulator (C) and the bleed-type  
master air valve (A), required in your system.  
6. Read and follow the instructions supplied with each  
component in your system.  
7. If the pump will be unattended for any period of  
time, if there is an air supply interruption, or at the  
end of the work shift, shut off the system and always  
relieve the pressure.  
2. Hold a metal part of the dispensing valve (H) firmly  
to a grounded metal waste container, and trigger the  
valve to relieve fluid pressure.  
Starting and Adjusting the Pump  
1. With the air regulator (C) closed, open the  
bleed-type master air valve (A).  
2. Open the dispensing valve (H) into a grounded  
metal waste container, making firm metal-to-metal  
contact between the container and valve.

Troubleshooting  
Troubleshooting  
Check all other possible problems and solutions  
before disassembling the pump. Before you trouble-  
shoot problems using the table below, relieve the  
pressure and disconnect the pump fluid line. If the  
pump starts when the air is turned on again, the  
fluid line, dispensing valve, etc., is clogged.

the pump and air motor. Use all the parts in the kit  
for the best results. Parts included in the kit are  
marked with one asterisk, for example (17*), in the  
text and drawings. See Parts, page 14.  
CAUTION  
Do not damage the plated surface of the trip rod (40).  
Damaging the surface of the trip rod can result in  
erratic air motor operation. Use the special padded  
pliers to grasp the rod.  
Two accessory tools should be used: Padded  
Pliers, 248198, are used to grip the trip rod without  
damaging its surface. Gauge, 15E796, is used to  
ensure the proper clearance between the poppets  
and seat of the transfer valve.  
9. Remove the six screws (9) holding the air motor  
cylinder (35) to the air motor base (28), and care-  
fully pull the cylinder straight up off of the  
piston (34).  
Disassembly  
1. Flush the pump, and relieve the pressure.  
CAUTION  
To avoid damaging the cylinder wall, lift the cylinder  
straight up off of the piston. Never tilt the cylinder  
while you are removing it.  
10. Pull the air motor piston/displacement rod assembly  
(29, 34) clear of the air motor base (28) by pulling up  
on the air motor piston.  
To reduce the risk of serious injury whenever you are  
instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 6.  
11. Remove the o–rings (13*, 103*) and u–cup  
packing (16*) from the air motor base (28). Use nee-  
dle–nose pliers to remove the u–cup packing from  
the bottom of the air motor base.  
2. Disconnect the ground wire from the grounding  
screw (28a), disconnect the hoses, remove the  
pump from its mounting, and clamp the air motor  
base in a vise horizontally by closing the vice jaws

by closing the vice jaws on the flats of the displace-  
ment rod.  
13. Clamp the displacement rod upright in the vice by  
closing the vice jaws on the flats of the displace-  
ment rod.  
2. Pull the new exhaust valve poppets (31*) into the  
valve actuator (27), and clip off the top parts of the  
poppets (shown with dotted lines in the Cutaway  
View in Fig. 4).  
14. Use a screwdriver to push down on the trip rod  
yoke (23) to snap the toggle assemblies (L) down.  
15. Remove the lockwires (25*) from the adjusting  
nuts (24*) of the transfer valves. Screw the top nuts  
off. Screw the valve poppet (32*) stems out of the  
grommets (17*) and bottom nuts (24*). Take the  
valve poppets off of the stems, and squeeze them  
firmly to check for cracks.  
3. Install the new grommets (17*) in the actuator (27),  
place the inlet valve poppets (32*) in the piston, and  
thread the bottom valve nuts (24*) onto the stems of  
the inlet valve poppets until there are a few threads  
left before the threads run out.  
If you thread the valve nuts too far down onto the  
poppets, they will run off the threaded part of the  
poppets.  
16. Grip the toggle arms (38) with pliers. Compress the  
springs (20) and swing the toggle assembly (L) up  
and away from the piston lugs (M), and remove the  
assembly. Check that the valve actuator (27) is sup-  
ported by the spring clips (26), but slides easily into  
them. See Fig. 4.  
4. Grease heavily and place the trip rod (40) in the air  
motor piston (34), place the actuator (27) in the  
yoke (23), and place the well–greased actuator/yoke  
assembly in the piston, with the trip rod going  
through the center holes of the actuator and yoke  
and the stems of the inlet valve poppets (32*) going  
through the grommets (17*).  
To reduce the risk of pinching or amputating your fin-  
gers, always keep fingers clear of the toggle  
assemblies (L).  
5. Thread the top valve nuts (24*) onto the stems of  
the inlet valve poppets (32*) until one thread of the  
inlet valve poppets is exposed above the valve nuts.  
17. Remove the trip rod yoke (23), actuator (27), and  
trip rod (40). Check the exhaust valve poppets (31*)  
for cracks.  
6. Install the toggle pins (36) in the yoke (23), place the  
toggle arm (38) ends of the toggle assembly (L)  
onto the toggle pins, and snap the pivot pin (37)  
ends of the toggle assembly into the piston lugs (M).  
To remove the exhaust valve poppets (31*), stretch  
them out and cut the end off with a sharp knife.  
7. Measuring with the gauge (Part No.15E796), create  
0.105 in. (2.7 mm) of clearance between the inlet  
valve poppets (32*) and the piston seat when the  
inlet valve is open. See the Cutaway View in Fig. 4.  
Clean and Service  
1. Clean all the parts carefully in a compatible solvent  
and inspect for wear or damage. Use all the repair  
kit parts during reassembly, and replace other parts  
as necessary.  
Adjust the distance between the inlet valve poppets  
and the piston seat by turning the top valve  
nuts (24*).  
2. Check the polished surfaces of the air motor  
piston (34), displacement rod (29), and cylinder  
wall (35) for scratches or wear. A scored rod will  
cause premature packing wear and leaking.  
8. Tighten the bottom valve nuts (24*) by hand. The  
grommets (17*) should be slightly compressed.  
3. Lubricate all parts with a light weight, water-resis-  
tant grease.

and break easily from too much bending.  
14. Clamp the air motor upright in the vice by closing  
the vice jaws below the flange.  
9. Align the holes in the valve nuts (24*) and the slots  
on the stems of the inlet valve poppets (32*). Drop  
the lock wires (25*) through the holes in the valve  
nuts and into the slots in the stems of the inlet valve  
poppets. Pull the lock wires down tightly, and bend  
the ends with pliers so that they cannot be pulled  
back out of the holes.  
15. Carefully lower the air motor cylinder (35) straight  
down onto the piston assembly (34). Tighten the six  
screws (9) holding the air motor cylinder to the air  
motor base (28).
