Refer to Disassembly Procedures of air motor for correct break
down.
OPERATING PROCEDURES
Disassembly should be done on a clean work bench with clean
cloths to keep parts clean.
x
x
The 9:1 ratio is an expression of the relationship between the effec-
tiveairmotorareaandtheeffectivelowerpumparea.When120PSI
(10 bar) of air pressure is supplied to the air motor, the lower pump
end will develop a maximum of 1,350 PSI (93 bar) of fluid pressure
(at no flow) as the fluid control is opened, the flow rate will increase
as the air motor cycle rate increases to keep up with the demand.
Flush system. This pump has been tested in kerosene and a small
amount remains in the pump end. Kerosene must be flushed from
the pump before using. To flush system:
If replacement parts are necessary, consult drawing containing
parts for identification.
Before assembling, lubricate parts where required. When assem-
bling“O”ringsorpartsadjacentto“O”rings, caremust beexercised
to prevent damage to “O” rings and “O” ring groove surfaces.

When the following instructions are observed, heavy paste materi-
alscanbepumpeddirectlyfromtheiroriginal5gallonpailwithoutair
inclusion, or excessive waste. The follower plate creates an air tight
seal as well as clean-wiping action in its progressive downward
movement into the pail.
Lubricate lower follower wiper plate seal with any type grease (sili-
cone, vaseline, gear, etc.). This ensures a smooth fit into the pail as
well as prevents curing type compounds from bonding to the seal.
Check vent plug to be sure it easily threads in and out. It is recom-
mended to lubricate the threads of the plug to help prevent possible
setupofcompoundatthispoint. See65184X-XOperator’sManual.
Regulate air pressure to a few pounds.
Connect air supply to air motor inlet.
Allow pump to cycle slowly and circulate solvent for awhile.
Disconnect air supply.

To Prime System:
Install gun or dispensing device to material outlet hose.
A shut-off valve located on the cart should be in the “off” position
(handle perpendicular to valve body). Connect air line to connector
(See figure 1).

With air line connected to connector, the lift assembly and pump will
rise.
Onceliftassemblyandpumpareinthe“up”position, placeandcen-
ter opened 5 gallon pail of material under follower plate (5).
Remove vent plug from follower plate (5). Trapped air must be re-
moved from beneath the follower plate.
Disconnectthemainairlinetotheconnectorandallowpumpandlift
assembly to lower into 5 gallon pail of material. Once the follower
plate (5) begins to force material out of the vent plug, reseat bleed
plug.
Once the follower has been properly seated, prior to pumping, be
sure the thumb screws on the cart are tightened to secure 5 gallon
pail. Pail must be locked in place with thumb screws before the fol-
lower plate can be removed from 5 gallon pail.
Djustment knob on air regulator (1) should be turned counter-clock-
wise until it turns free to prevent overpressurizing the pump.
Connect air line to air regulator (1). Adjust knob on the air regulator
(1) until pump begins to cycle.
Trigger (13) gun to prime pump with material.
If pump does not stop or material does not flow from dispensing
valve, refer to Troubleshooting Section of this manual.
