WARNING  
SKIN INJECTION HAZARD  
Fluid from the dispensing valve, leaks, or ruptured components can inject fluid into your body and  
cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on  
the skin can also cause serious injury.  
D Fluid injected into the skin may look like just a cut, but it is a serious injury. Get immediate  
surgical treatment.  
D Do not point the dispensing valve at anyone or at any part of the body.  
D Do not put your hand or fingers over the end of the dispensing valve.  
D Do not stop or deflect leaks with your hand, body, glove or rag.  
D Use only extensions and no-drip tips that are designed for use with your dispensing valve.  
D Tighten all fluid connections before you operate this equipment.  
D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately. Do  
not repair high pressure couplings; you must replace the entire hose.  
HAZARDOUS FLUIDS  
Improper handling of hazardous fluids or inhaling toxic fumes can cause extremely serious injury,  
even death, due to splashing in the eyes, ingestion, or bodily contamination.  
D Know the specific hazards of the fluid you are using.  
D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,  
state, and national guidelines.  
D Always wear protective eyewear, gloves, clothing, and respirator as recommended by the fluid

Installation  
D Install an air line filter (B) to remove harmful dirt  
System Accessories  
and contaminants from your compressed air supply.  
CAUTION  
D Install a bleed-type master air valve (A) to isolate  
the accessories for servicing. See Fig. 1. To order  
a bleed-type master air valve, order Part No.  
107142.  
Do not hang the air accessories directly on the air  
inlet (E). 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.  
As an alternative to a bleed-type master air valve,  
you can install an air line quick disconnect coupler  
(M) and fitting (L) to serve as an air-bleed device.  
See Detail A in Fig. 1.  
NOTE: Install the following accessories in the order  
shown in Fig. 1.  
D Install a ball valve (F), at the end of a line drop, as  
shown in Fig. 1, for releasing moisture that collects  
in the line.  
WARNING  
Four accessories are required in your system: an  
air shut-off valve/air bleed device, fluid drain valve,  
thermal relief kit, and ground wire. These accesso-  
ries help reduce the risk of serious bodily injury  
including fluid injection, splashing in the eyes or on  
the skin, injury from moving parts if you are adjust-  
ing or repairing the pump, and explosion from  
static sparking.  
D Install a drain valve (H) near the pump fluid outlet to  
relieve fluid pressure in the hoses and gun when  
opened. To order a fluid drain valve, order Part No.  
210658.  
D Install a pump runaway valve (D) to shut off the air  
to the pump if the pump accelerates beyond the  
pre-adjusted setting, which can be caused by a  
depleted fluid supply. A pump that runs too fast  
can be seriously damaged. To order a 3/4-in. npt(f)  
inlet and outlet pump runaway valve, order Part No.  
215362.  
The air bleed device relieves air trapped between it  
and the air motor after the air supply is shut off.  
Trapped air can cause the air motor to cycle unex-  
pectedly, causing serious bodily injury if you are  
adjusting or repairing the pump. Use either a  
bleed-type master air valve (A) or a quick-discon-  
nect coupler (M) and fitting (L). Install near the  
pump air inlet, within easy reach of the pump.  
D Install a thermal relief kit (K) on the dispensing  
valve side of the pump. To order a 1600 psi  
(110 bar) thermal relief kit, order Part No. 240429.  
The fluid drain valve (H) assists in relieving fluid  
pressure in the displacement pump, hoses, and  
dispensing valve. Triggering the valve to relieve  
pressure may not be sufficient.  
D Install a suitable fluid hose (P) and dispensing  
valve (J).  
Wall Mount  
The pump shown in Fig. 1 is a wall-mounted universal  
pump, Model 205626. To order the wall-mounting  
bracket shown, order Part No. 238245.  
The thermal relief kit assists in relieving pressure in  
the pump, hose, and dispensing valve due to heat  
expansion.  
The ground wire reduces the risk of static sparking.  
Cover Mount  
Pump Model 222065 is designed for mounting directly  
on a 55-gallon drum cover. When the pump is  
mounted to a closed-head drum, be sure you loosen  
the vent plug on the drum cover to prevent a vacuum  
in the drum. For cover mounting, see the Mounting  
Hole Layout on page 16.  
D Screw the muffler (5) into the 3/4-in. npt muffler  
port, and tighten it using a wrench on the flats of  
the muffler near the male threads.  
D Install an air line lubricator (N) for automatic air  
Bung Mount  
motor lubrication.  
Pump model 222095 is designed for bung mounting on  
a 55-gallon drum. The bung adapter (153) is shown in  
the Parts Drawing on page 15.  
D Install the air regulator (C) to control pump speed  
and pressure.

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.  
Proper grounding is an essential part of maintaining a  
safe system.  
To 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 this equipment:  
D Pump: Use a ground wire and clamp as shown in  
Fig. 2.  
D Air and Fluid hoses: Use only electrically conduc-  
tive hoses.  
D Air compressor: Follow the manufacturer’s recom-  
mendations.  
Y
D Fluid supply container: Follow the local code.  
D Object being lubricated: Follow the local code.  
Z
D To 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.

Operation  
Pressure Relief Procedure  
WARNING  
HAZARDOUS VAPORS  
The air motor exhaust coming out of the  
muffler could contain harmful materials,  
such as oil, antifreeze, or some of the  
material being pumped.  
WARNING  
SKIN INJECTION HAZARD  
To reduce the risk of serious bodily  
injury, including fluid injection or  
splashing in the eyes or on the skin,  
always follow this procedure whenever you shut off  
the pump, check or service any part of the system,  
install or change dispensing devices, and when you  
stop dispensing.  
WARNING  
MOVING PARTS HAZARD  
Do not operate the pump without the  
muffler installed. When the muffler is not  
installed, the air motor is exposed, and it  
could cut your fingers if they are pushed into the  
muffler opening.  
1. Close 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, or open the  
drain valve (H).  
1. With the air regulator (C) closed, open the bleed-  
type master air valves (A) or, if so equipped, join  
the quick disconnect coupler (M) to the male fitting  
(L).  
If you suspect that the nozzle or hose is completely  
clogged, or that pressure has not been fully relieved  
after you have followed the steps above, do the follow-  
ing: Wrap a rag around the hose end coupling, and  
relieve pressure gradually by very slowly partially  
loosening the fitting. Then loosen completely, then  
clear the obstruction.  
2. Open the dispensing valve (J) into a grounded  
metal waste container, making firm metal-to-metal  
contact between the container and valve.  
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 dispensing valve.  
Startup and Adjustment  
WARNING  
COMPONENT RUPTURE HAZARD  
The maximum working pressure of each  
component in the system may not be the  
same. To reduce the risk of overpres-  
NOTE: When the pump is primed, and with sufficient  
air supplied, the pump starts when the dis-  
pensing valve is opened and shuts off when it  
is closed.  
4. If your system is equipped with a runaway valve (D  
in Fig. 1), set it for your system configuration. See  
manual 308201 for instructions on setting the  
pump runaway valve.  
surizing any component in the system, be sure you  
know the maximum working pressure of each  
component, including the air motor and pump.  
Never exceed the maximum working pressure of  
the lowest rated component in the system. Over-  
pressurizing any component can result in rupture,  
fire, explosion, property damage, and serious  
injury.  
5. Adjust the air regulator until you get sufficient flow  
from the dispensing valve. Always run the pump  
at the lowest speed necessary to get the desired  
results. Do not exceed the maximum working  
pressure of any component in the system.  
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:  
6. If your pump accelerates quickly or is running too  
fast, stop it immediately, and check the fluid sup-  
ply. 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  
compatible solvent. Be sure to eliminate all air  
from the fluid lines. If your system has a runaway  
valve, reset it according to the instructions in  
manual 308201.  
10 (:1) ratio x 180 psi air =  
1800 psi fluid output  
[10 (:1) ratio x 12.4 bar air = 124 bar fluid output]  
Limit the air to the pump so that no air line or fluid  
line component or accessory is overpressurized.

Disassembly  
NOTE: Clean and inspect all parts for wear or damage  
as you disassemble them. Replace parts as  
needed. For best results, always replace all  
the o-rings and packings when you disassem-  
ble the pump.  
NOTE: Be sure you have all necessary parts on hand.  
Repair Kit 238751 includes repair parts for the  
air motor and pump. Use all parts in the kit for  
the best results. Parts included in the kit are  
marked with one asterisk, for example (19*), in  
the text and drawings. See the Parts List on  
page 14.  
1. Relieve the pressure.  
2. Follow steps 1 to 7 of Disassembly on page 9.  
1. Flush the pump.  
3. Carefully inspect the smooth inner surface of the  
fluid cylinder (110) for scoring or scratches. Such  
damage causes premature seal wear and leaking.  
Replace the cylinder as needed.  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 7.  
Reassembly  
Do steps 16 through 26 in Air Motor and Throat
