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.

:
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.

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.

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.
