TO RAISE THE 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 of RM052S-X Two Post
Lift / Ram Operator's Manual.
2.
Connect the air supply (125 p.s.i. / 8.6 bar max.) to the air inlet.
Adjust the air pressure on the lift / ram pressure regulator (turn
the knob clockwise) to 20 p.s.i. (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 fi t 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 (see RM052S-X Operator's Manual).
TO LOWER LIFT:
PINCH HAZARD. Follower can descend quickly,

causing injury. Keep hands clear when aligning with con-
tainer. Read the warnings on page 2 of RM052S-X Two Post Lift
/ Ram Operator's Manual.
NOTE: Be certain the follower plate vent plug has been removed
so that the air trapped between the follower and the material is al-

als can be pumped directly from their original drum without air
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 drum.

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.
The unit is now ready for operation. Open the pump air supply
valve. Adjust the air pressure on the pump fi lter / regulator (turn
the pump regulator knob clockwise) until the pump begins to
cycle.
4.
Trigger the gun to prime the pump with material.
TO RAISE LIFT, (NORMAL OPERATION):
1.
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 THE DRUM:
NOTE: The control valve lever must 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 the cover.
