GENERAL DESCRIPTION
The ARO Model 651612-X Two Post Lift / Ram is used to help force high
viscosity materials or greases into the pump material inlet. This unit uses
dual 5-1/2’’ air operated cylinders welded to a heavy gauge plate and a
tubular steel cross member to raise and lower a fluid handling pump as-
sembly into and out of a standard 55 - gallon drum.
The cast aluminum follower is fitted with a dual-lipped seal to wipe the
drum clean and seal off the material from the atmosphere. Several fol-
lower plate outer seal material options are available to be compatible
with the material being pumped. In a typical configuration the pump low-
er pump end is securely attached to the follower plate and is further sta-
bilized by a support bracket assembly. Hold down brackets located on
each of the cylinders help to properly position drum with the follower
plate each time the drum is changed.
It is best to permanently fasten the lift / ram to the floor. Once the unit has
been properly anchored in concrete, this unit has the ability to raise a
pump 38-1/4” (to clear a standard 55 - gallon drum.) The operator is then
able to easily remove a pump and follower assembly from a drum in or-
der to exchange drums.
This unit uses a lever type control valve which controls the air necessary
to raise and lower thelift. This type of valve exhausts through aport in the
valve.
The lift also includes an auxiliary manual air valve which is used to sup-
ply a controlled amount of air to the follower plate. A small amount of air
supplied under the follower plate will help to raise the follower plate,
pump and lift by relieving the vacuum.

OPERATING AND SAFETY PRECAUTIONS
ZRead and heed all Warnings, Cautions and Safety Precautions
before operating.
ZUse only genuine ARO replacement parts to assure compatible
pressure rating and longest service life.
WARNING THE LIFT MUST BE SECURELY ANCHORED IN
CONCRETE. DO NOT ATTEMPT TO USE THE LIFT UNTIL ALL
POSSIBLE MEASURES HAVEBEEN TAKEN TO INSURE THAT
THE LIFT HAS BEEN PROPERLY INSTALLED AND THEBASE
IS SECURELY FASTENED. It is the duty of the installer to provide
anchor bolts / studs (not included) and for them to be securely em-
bedded in concrete which is more than 2’’ thick. An improperly se-
cured lift is unsafe.
WARNING PREVENT ELECTRIC SHOCK. BE CERTAIN THE
AREAABOVETHELIFTISCLEAR OFELECTRICALFIXTURES,
DEVICES AND WIRING(minimum of 100”is required.) Examine
the working area and take necessary action to assure adequate
clearance for the lift and pump assembly to raise to the fullest limit
and function properly.
WARNING DO NOT EXCEED MAXIMUM INLET PRESSURE
OF 100 p.s.i. (6.9 bar). OPERATINGLIFT AT HIGHER PRES-
SURE MAY CAUSE LIFT DAMAGE AND /OR PERSONAL INJU-
RY AND /OR PROPERTY DAMAGE.
WARNING DO NOT EXCEED DRUM PRESSURE LIMITS.
Know the pressure limitations of the drum and regulate the air pres-
sure within safe limits when supplying air to the follower plate.
WARNING AVOID POSSIBLE INJURY. KEEP HANDS, ARMS
AND FEET CLEAR OF DRUM WHEN LIFT IS ASCENDINGAND
DESCENDING.Do not attempt to reposition the pump by grasping
the follower plate. In the raising and lowering function, the air is re-
stricted through a secondary restrictor orifice (in addition to the air
valve). In a situation where the lift could get hung up or the descent is
restricted temporarily, the lift could in some cases drop rapidly and
be hazardous. If the follower plate does not enter the drum properly,
DO NOT ATTEMPT TO REPOSITION IT WITH YOUR HANDS; rai-
se the lift and restart.
WARNING STAND CLEAR WHEN RAISINGOR LOWERING
THE LIFT. It is good safety practice to stay clear of a raised lift and
operate it from a safe position. When using the larger size pumps
(10” & 12”) the clearance of the air motor and cross tube are quite
close, KEEP HANDS AWAY FROM THIS AREA ANY TIME THE
PUMP IS DESCENDING.
WARNING DO NOT SERVICE OR CLEAN LIFT, PUMP,
HOSES OR DISPENSINGVALVEWHILE THE SYSTEM IS PRES-
SURIZED AS SERIOUS PERSONAL INJURY COULD RESULT.
First disconnect air line; then releive pressure from system by open-
ing valve or device and / or carefully and slowly loosening and re-
moving outlet hose or piping from the pump.
CAUTION BE CERTAIN ALL OPERATORS OF THIS EQUIP-
MENT HAVE BEEN TRAINED FOR SAFE WORKING PRACTIC-
ES, UNDERSTAND IT’S LIMITATIONS AND WEAR SAFETY
GOGGLES / EQUIPMENT WHEN REQUIRED.

GENERAL LIFT INSTALLATION INSTRUCTIONS
1. The area above the lift work area must be clear and without obstruc-
tions and safely away from anything electrical.
2. THE LIFT BASE SHOULD BE SECURELY ANCHORED IN CON-
CRETE. Anchor bolts / studs must be embedded in AT LEAST 2”of
good concrete is recommended. The base itself can be used for a
template for establishing the proper anchor locations.
3. Install an air shut-off valve between air source and pump air inlet.
NOTE: One of the available F-R-L combinations should be used with the
ram. Refer to page 5.

651612-XPAGE4OF8
INITIAL SET-UP PROCEDURE
1. Assemble pump to follower plate.
2. Place pump on follower plate and secure with the proper fasteners.
3. Mount 91519 mounting plate to bottom of air motor only if a 4-1/4” or
6” air motor is going to be used. Be sure support rods are properly
placed in the 14” (35.6 cm) location to mount air motor. Use the
17-7/8” (45.4 cm) support rod spacing for the 8”, 10” or 12”.
NOTE: It may be necessary to loosen pump spacer rods nuts in order to
re-index the air motor on the pump to a more favorable position.
4. Place two support brackets around base of the air motor and secure
with four Y6-65-C 1” long screws, four Y16-616 lockwashers and
four Y12-6-C jam nuts.
5. Install an air shut-off valve between air source and pump.
NOTE: This is important for pump control when the pump and follower
are in the “UP” position.
LIFT OPERATION
TO RAISE LIFT:
1. Connect air supply 100 p.s.i. (6.9 bar) to air regulator coupler (not
supplied).
2. Adjust air regulator pressure to between 30 and 40 p.s.i. (2.1 and 2.8
bar).
3. Remove vent plug.
4. Rotate lift valve lever to the “UP” position to raise lift. Be certain the
lift is clear of any objects above. Also refer to “OPERATING AND
SAFETY PRECAUTIONS” found on page 2.
5. Raise the lift to desired height to clear drum. Stop lift upward travel
by rotating lift valve lever to the “NEUTRAL” position.
TO LOWER LIFT:
SAFETY NOTE:The lift may hesitate before starting downward, the air
pressure inside the lift post air chamber must decrease before it will be-
gin to descend.
NOTE:The lift valve should be in the “NEUTRAL” position.
1. Place the drum in position securely against barrel guides and adjust
if needed.
2. Align pump and follower with drum.
3. Turn lift valve lever to the “DOWN” position to begin lowering.
WARNING BE CERTAIN HEAD, HANDS AND ARMS ARE
CLEAR OF ASCENDINGAND DESCENDINGLIFT. Refer to “OP-
ERATINGAND SAFETY PRECAUTIONS”on page 2.
4. Gradually work the follower seal into the drum, be certain the vent
plug has been remove (as applicable) so that the air trapped be-
tween the follower and the material is allowed to escape.
5. Air trapped between material and follower will purge through the
vent plug opening. When material “oozes” from the vent, replace the
vent plug. The lift valve lever should remain in the “DOWN” position.
6. At this point the pump should be started and allowed to prime. After
the pump has cycled several times, all the trapped air should be
purged from the pump, hose assembly, and the extrusion gun. A
steady stream of material from the nozzle indicates the system is
primed and ready to operate. Pump should stall out or remain static
when extrusion gun is in the “OFF” position.
7. Should pump continue to cycle after extrusion gun is in the “OFF”
position, increase the air pressure to the lift valve to a higher setting;
this increases the force exerted by the two cylinders and the follower
plate on the material.
8. If this does not remedy the problem; increase the setting in incre-
ments of 10 p.s.i. (0.7 bar) up to 90 p.s.i. (6.2 bar) or purge the
trapped air under the follower plate or in the system.
TO CHANGE DRUMS:
CAUTION DO NOT EXCEED MAXIMUM PRESSURE LIMITA-
TIONS OF DRUM AS INDICATED BY DRUM SUPPLIER /
MANUFACTURER.
1. Disconnect air supply to pump.
2. When utilizing the follower air valve assist feature; open the follower
plate air supply valve supply an amount of air sufficient to help the lift
raise the pump through the material drum.
3. SLOWLY rotate lift valve lever to “UP” position and raise lift by throt-
tling the lift valve.
4. When the follower plate air supply is no longer needed; turn off air
valve and remove vent plug.
5. Replace drum.
6. Repeat steps under “TO LOWER LIFT” section.
