Installation
Mount the pump to suit the type of installation planned.
Very heavy lubricants may require an inductor plate.
See page 16 for the mounting hole layout and
dimensions
WARNING
A bleed-type master air valve (B) is required to
shut off and relieve air pressure that may be
trapped in the air motor. Trapped air could cause
the pump to cycle unexpectedly and cause serious
bodily injury, including amputation.
Install the air line accessories in the approximate order
shown in the Typical Installation. Install a bleed-type
master air valve (B) within easy reach of the pump,
upstream from the air regulator. Install an air filter (C)
to remove harmful dirt and moisture from your
compressed air supply. For automatic air motor
lubrication, install an air line oiler (D) close to the pump
air inlet. Install an air regulator (E) to control pump
speed.
Be sure the air hose is properly sized to deliver an
adequate supply of air to the motor. Refer to the
Technical Data on page 17.
Connect a dispensing hose to the 3/4 npt(f) pump
outlet. Install an appropriate gun or dispensing valve to

Operation
Startup and Adjustment
WARNING
Open the bleed-type master air valve. Open the
dispensing valve, and slowly open the air regulator
until the pump is running smoothly. After all the air is
purged, close the dispensing valve. The pump will
start and stop as the valve is opened and closed.
D This pump is designed to be used ONLY in
pumping non-corrosive and non-abrasive lubri-
cants and greases. Any other use of this pump
can cause unsafe operating conditions and
result in component rupture, fire, or explosion,
which can can cause serious bodily injury,
including injection.
CAUTION
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed and may damage itself. If your pump acceler-
ates 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 the pump and
leave it filled with a compatible solvent. Be sure to
eliminate all air from the fluid system.
D Moving parts can pinch or amputate your fin-
gers or other body parts. When the pump is
operating, the priming piston (located at the
pump intake) and the air motor piston (located
behind the air motor plates) move. NEVER
Operate the pump with the air motor plates
removed, and keep your fingers and hands
away from the priming piston.
Use the air regulator (E) to control the pump speed
and fluid pressure. See Fig. 2. Always use the lowest
pressure necessary to obtain the desired results.
Pressure Relief Procedure
WARNING
When you are finished using the pump for the day,
always follow the Pressure Relief Procedure at left.
SKIN INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause
serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you
Maintenance
The Accessory air line oiler (D) provides automatic air
motor lubrication. For daily manual lubrication,
disconnect the air hose, place about 15 drops of light
machine oil in the air inlet, reconnect the hose, and
turn on the air supply to blow oil into the motor.
D Are instructed to relieve the pressure
D Stop dispensing
D Check or service any of the system equipment
D Install or clean the dispensing nozzles
1. Close the air regulators.
2. Close the supply pump’s bleed-type master air
valve (required in this system).
3. Open the dispensing valve until pressure is fully
relieved.
If you suspect that the dispensing valve, extension, or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after following the steps above,
VERY SLOWLY loosen the coupler or hose end
coupling and relieve pressure gradually, then loosen
completely, then clear the clog.

from the piston housing (16).
9. Clean and inspect all the parts.
Reassembly
Before you start:
1. Reassemble the piston, using all the new parts
from the kit and any other new parts needed. Oil
the leather cup packings (36*) first. Then assemble
the parts on the piston housing (16) in this order:
backup washer (35*), spreader (34*), leather
packing (36*), cup spacer (20) with new o–ring
(33*) installed in it, another leather packing (36*),
spreader (34*), and backup washer (35*).
D To reduce down time, be sure you have all
necessary repair parts available.
D Repair Kit 237498 is available. If you have a repair
kit, use all the new parts for the best results. Parts
included in the kit are marked with an asterisk (*).
D When cleaning parts, use a compatible solvent.
Inspect parts for wear or damage and replace as
necessary. Scoring or irregular surfaces on the
priming rod (8) or polished inner wall of the riser
tube (2) causes premature packing wear and
leaking. Check these parts by rubbing a finger on
the surface and by holding the parts up to the light
at a slight angle.
NOTE: To replace the throat packings, follow the
procedure given in your separate air motor manual
(306982) before continuing with the procedure.
2. Screw the piston assembly onto the connecting
rod (3) and adjust the ball travel as instructed in
Check Valve Adjustment on page 12. Tighten the
locknut (4).
3. Check the o–ring (13) in the pump base and
replace it, if necessary.
Use light, waterproof grease wherever grease is
mentioned.
4. Lubricate the piston packings and the inner wall at
the top of the riser tube (2). Wrap the packings
with with a guide collar made of 1/64 in. maximum
thickness shim stock or metal sheeting. Using a
turning motion, work the first leather packing into
the riser tube. Remove the guide collar and push
the riser tube up and screw it into the base. Torque
the tube to 100–150 ft.–lb. (135–204 N–m).
Disassembly
1. Follow the Pressure Relief Procedure on page
7.
2. Remove nut (10) and priming plate (9) from
priming rod (8).
3. Unscrew the foot valve housing (7) from cylinder
(2).
5. Slide bearing (5) onto priming rod (8) with the step
side facing the bottom of the pump.
NOTE: Poppet check (6) foot valve packings and
bearings (5) slide off priming rod (8) when
removing foot valve housing.
6. Insert foot valve packings (30) into poppet check
(6) replace if necessary.
4. Unscrew bearing (5) from foot valve (7).
7. Slide poppet check containing foot valve packings
onto priming rod (8) with beveled edge facing the
bottom of the pump.
5. Remove the poppet check (6) and inspect foot
valve packings (30).
6. Unscrew riser tube (2) from pump base. Clean the
tube and inspect it for wear by holding it up to a
light at a slight angle. If you see wavy lines or
scratches where the piston travels, replace the
tube as it will not seal well with the new piston
packings and the pump will perform poorly.
8. Slide foot valve over poppet check and screw
bearing (5) into the foot valve (7).
9. Push foot valve up to the riser tube.
10. Inspect o–ring (11) for damage and replace if
necessary.
7. Loosen the lock nut (4) and unscrew the valve
housing (14) from the connecting rod (3), unscrew
valve housing (14) from piston housing (16).

and tighten.
To change the piston ball travel, loosen the locknut (4).
Turn the piston valve housing (14) counterclockwise to
increase and clockwise to decrease. Medium viscosity
fluids should have a 3/16 in. (5 mm) ball travel.
Decreasing the ball travel minimizes surging at stroke
changeover; however, too short of ball travel restricts
the flow and slows down the pump.
13. Reconnect the pump’s ground wire to a true earth
ground.
