WARNING:
Wear protective clothing, gloves, and safety glasses when
lowering the follower plate into the container. The expelled air from under
the follower plate may contain material.
NOTE:
It may be necessary to increase the cylinder pressure when using
high-viscosity material to ensure proper operation of the cylinder assembly
and to prevent the pump from losing contact with the material. Use the
minimum air pressure necessary to operate the elevator.
12. Place the elevator control valve (4) in the
Ram Down
position and slowly
lower the follower plate (5) into the open container of material. To stop
the follower plate, place the elevator control valve in the
Neutral
position.
13. Perform the following:
a. When material begins to flow from the fitting on the bleeder
stem/blow-off port (6), place the elevator control valve in the
Neutral
position.
b. Install the bleeder stem (8) into the bleeder stem/blow-off port and
tighten securely. Use a rag to remove excess material around the
the bleeder stem/blow-off port.
14. Place the elevator control valve (4) in the
Ram Down
position to force
material into the pump.
WARNING:
To prevent personal injury, do not open the bleed valve more
than two or three turns.
15. Bleed the pump:
a. Carefully loosen the bleed valve (10) only two or three turns. Do not
remove the bleed valve.
b. Leave the valve open until the material flow is continuous and any
trapped air in the hydraulic section vents.
c. Tighten the bleed valve.
16. Make sure that the hose and applicator are secured and that the
applicator is not pointing at any personnel in the area.
17. Trigger the applicator(s) to bleed off air in the lines.
18. Open the air motor ball valve (1) and adjust the air motor regulator (2) to
increase pressure until the pump begins to operate. Operate the pump
until the applicator dispenses material that flows smoothly, continuously,
and without air bubbles.
