TO RAISE LIFT, (THE FIRST TIME):
1. Take note of the pump / drum clearance above. Be certain the
lift / ram is clear of any objects above. Also, refer to “Operating
and Safety Precautions”, found on page 2.
2. Connect the air supply (125 psig / 8.6 bar maximum) to the air
inlet. Adjust the air pressure on the lift / ram pressure regulator
(turn knob clockwise) to 20 psig (1.4 bar).
3. Shift the control valve lever to the “up” position.
4. Raise the lift / ram high enough to clear the height of the drum.
Stop the lift upward travel by moving the control valve lever to
the “neutral” (center) position.
5. Once the lift / ram assembly and pump are in the “up” position,
place and center an opened drum of material on the lift / ram
base.
6. Lubricate the lower follower wiper plate seal with grease.
NOTE:
Make certain the grease is compatible with the material being
dispensed. This ensures a smooth fit into the drum, as well as
prevents curing type compounds from bonding to the seal.
7. Check the vent plug on the follower plate to be sure it easily
threads in and out. It is recommended to lubricate the threads
of the plug to help prevent possible set up of the compound at
this point.
TO LOWER LIFT:
WARNING
PINCH HAZARD. Follower can descend quickly,
causing injury. Keep hands clear when aligning with con-
tainer. Read the warnings on page 2.
NOTE:
Be certain the follower plate vent plug has been removed
so that the air trapped between the follower and the material is al-
lowed to escape from this vent.
NOTE:
The lift / ram may hesitate momentarily before starting
downward. The air pressure inside the post air chamber must de-
crease before it will begin to descend.
1. Shift the control valve lever to the “down” position and proceed
to lower the pump.
2. Replace the vent plug once the material begins to ooze from
the vent opening.
3. Models RM072S-CXX-XX: The unit is now ready for operation.
Open the pump air supply valve. Adjust the air pressure on the
pump filter / regulator (turn the pump regulator knob clock-
wise) until the pump begins to cycle.
4. Trigger the gun to prime the pump with material.
TO RAISE LIFT, (NORMAL OPERATION):
1. Models RM072S-CXX-XX: Close the pump air supply valve.
2. Shift the control valve lever to the “up” position.
3. Raise the lift / ram high enough to clear the height of the drum.
Stop the lift upward travel by moving the control valve lever to
the “neutral” (center) position.
TO CHANGE DRUM:
NOTE:
The control valve lever should be in the “neutral” position
and the pump air supply valve should be closed.
1. To avoid damage, DO NOT OVER-PRESSURIZE THE DRUM.
2. Open the follower plate air supply valve to allow air under the
follower plate.
3. Shift the control valve lever to the “up” position.
4. Place and center a new drum into position. Remove cover.
