AIR AND LUBE REQUIREMENTS
yExcessive air pressure will shorten the life of the pump. Do not
operate pump above recommended maximum air pressure.
For maximum operating eciency, the following air supply speci-
cation should be maintained to this pump:
yAIR PRESSURE - Refer AF0409AX1XX pump manual for maxi-
mum pressure note.
yAIR FILTRATION - 50 micron
yLUBRICATED AIR SUPPLY
yAIR INLET SIZE - 1/2” N.P.T.F. - 1
Filtered and oiled air will allow the pump to operate more ecient-
ly and yield a longer life to operating parts and mechanisms.

TO CHANGE THE PAIL
yTurn knob on pump air regulator (1) counter-clockwise to turn
air “o” to pump.
yTurn shut-off control valve to “ON” position (Handle parallel
with body) to apply pressure under follower plate.
yDisconect main air line from pump air regulator (1) and con-
nect to air line connector on cart.
yAllow pump and lift assembly to clear the top of the 5 gallon
pail of material.
yTurn shut-o controll valve tp “OFF” postition. (Handle perpen-
dicular to valve body).
yUnscrew thumb screws. Remove empty pail of material and
replace with a new pail of material.
ySecure new pail of material with thumb screws. Remove vent
plug from follower plate.
yDisconnect main air line from connector and allow lift assembly
to lower into new 5 gallon pail of material. Once the follower
plate begins to force material out of the vent plug, reseat bleed
plug.
OPERATING PROCEDURES
Flush system:
yThis pump has been tested in oil and a small amount remains
in the pump end. Oil must be ushed from the pump before
using. To ush system:
yGun or dispensing device should be removed.
yImmerse uid or suction hose in a 5 gallon pail of compatible solvent.
yPlace material outlet hose into pail.
yRegulate air pressure to a few pounds.
yConnect air supply to air motor inlet.
yAllow pump to cycle slowly and circulate solvent for awhile.
yDisconnect air supply.
To Prime System:
yInstall gun or dispensing device to material outlet hose.
yA shut-o valve located on the cart should be in the “o” posi-
tion (handle perpendicular to valve body). Connect air line to
connector.
yWith air line connected to connector, the lift assembly and
pump will rise.
yOnce lift assembly and pump are in the “up” position, place and
center opened 5 gallon pail of material under follower plate (5).
yRemove vent plug from follower plate (5). Trapped air must be
removed from beneath the follower plate.
yDisconnect the main air line to the connector and allow pump
and lift assembly to lower into 5 gallon pail of material. Once
the follower plate begins to force material out of the vent
plug, reseat bleed plug.
yOnce 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 follower plate can be removed from 5 gallon pail.
yOnce 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 follower plate can be removed from 5 gallon pail.
yConnect air line to air regulator. Adjust knob on the air regula-
tor until pump begins to cycle.
yTrigger gun to prime pump with material.
yIf pump does not stop or material does not ow from dispens-
ing valve, refer to Troubleshooting Section of this manual.
DAILY MAINTENANCE
yLack of or an excessive amount of lubrication will aect the perfor-
mance and life of this pump. Use only recommended lubricants.
yDAILY - Fill air line lubricator reservoir with SAE NO. 90W non-
detergent gear oil.
yIf pump is to be inoperative for more than a few hours at a time,
disconnect air supply and relieve all pressure from the system.
yThis manual covers the basic pump unit. The 4-1/4” air motor is
completely separate from the lower pump end. This helps to keep
the air motor from being contaminated by material being pumped.
yPeriodically flush entire pump system with a solvent that is
compatible with the material being pumped.
yKeep solvent cup lled with this compatible solvent. This will
keep material from drying on the piston rod, which would drag
thru the packings, ruin them and eventually scour the piston
rod.
yRefer to Disassembly Procedures of air motor for correct break
down.
yDisassembly should be done on a clean work bench with clean
cloths to keep parts clean.
yIf replacement parts are necessary, consult drawing containing
parts for identication.
yBefore assembling, lubricate parts where required. When assem-
bling “O” rings or parts adjacent to “O” rings, care must be exer-
cised to prevent damage to “O” rings and “O” ring groove surfaces.
MAINTENANCE
yWhen the following instructions are observed, heavy paste
materials can be pumped directly from their original 5 gallon
pail without air inclusion, or excessive waste. The follower plate
creates an air tight seal as well as clean-wiping action in its pro-
gressive downward movement into the pail.
yLubricate lower follower wiper plate seal with any type grease
(silicone, vaseline, gear, etc.). This ensures a smooth t into the
pail as well as prevents curing type compounds from bonding
to the seal.
yCheck vent plug to be sure it easily threads in and out. It is rec-
ommended to lubricate the threads of the plug to help prevent
possible set up of compound at this point. See Follower Plate
Operator’s Manual.
TROUBLESHOOTING
Material leakage around the Control Handle.
yMalfunctions beyond the scope of this manual should be
brought to the attention of your ARO Representative..
No material coming from extrusion nozzle.
yObstructed Material, Remove tip and clean.
yObstructed Hose, Remove control handle and cycle pump until
hose is clear.
yObstructed Control Handle, Disassemble control handle and
clean.
