INSTALLATION
The HD0844S5XXXXXXXX Extrusion System comes complete- ly assembled. Remove the unit from the crate and place on a level surface. Install the material hose and dispensing device as required.
When the following instructions are observed, heavy paste
materials 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

TO RAISE THE LIFT, (the first time):
1.Take note of the pump / drum clearance above. Be cer- tain the lift / ram is clear of any objects above. Also, refer to “Operating and Safety Precautions” found on page 3 of
2.Connect the air supply (100 p.s.i. max.) to the air inlet. Adjust the air pressure on the lift / ram pressure regula- tor (turn the knob clockwise) to 30 - 40 p.s.i. (2.1 - 2.8 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 and securely against the barrel guides, adjusting if necessary.
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
TO LOWER LIFT:
WARNING PINCH HAZARD. Follower can descend quickly, causing injury. Keep hands clear when align- ing with container. Read the warnings on page 3 of
NOTE: Be certain the follower plate vent plug has been re- moved so that the air trapped between the follower and the material is allowed to escape from this vent.
NOTE: The lift / ram may hesitate momentarily before start- ing downward. The air pressure inside the post air chamber must decrease 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. Adjust the air pres- sure on the pump filter / regulator (turn the pump regu- lator knob clockwise) until the pump begins to cycle.
4.Trigger the gun to prime the pump with material.
TO RAISE LIFT, (normal operation):
1.Adjust the follower plate air valve pressure up to approx- imately 8 p.s.i.g. (0.55 bar). DO NOT OVER PRESSURIZE THE DRUM to avoid damage. NOTE: Air from this valve will only pass when the control lever is in the “up” posi- tion.
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” posi- tion.
1.Remove the old drum.
2.Place and center a new drum into position.
