Load Material
NOTE: Before loading material, ensure that there is a
minimum overhead clearance of 20 in. (51 cm) and all
air regulators are backed off to their full counterclock-
wise position.
1. Close all air regulators and air valves. See F
IG
. 3 on
page 7.
2. Open the main air ball valve (BA) and set the ram
air regulator (BB) to 40 psi (0.28 MPa, 2.8 bar). Set
the director valve handle (BC) to the UP position
and let the ram rise to its full height.
3. Lubricate the platen seals with grease or other lubri-
cant compatible with the fluid you will pump.
4. Remove the drum cover and smooth the surface of
the fluid with a straightedge.
5. Put a full drum of fluid on the ram base, slide it back
against the drum stops, and center it under the
platen.
6. Remove the bleed stick (DE) from the platen bleed
port. See F
IG
. 16.
7. If the drum has a plastic liner, pull it over the edge of
the drum. Secure the liner with tape wrapped
around the circumference of the drum.
8. Set the director valve (BC) to the DOWN position
and lower the ram until fluid appears at the top of
the platen bleed port. Adjust the ram air regulator
(BB) as needed. Set the director valve (BC) to neu-
tral and close the platen bleed port (G).
NOTICE
Do not use a drum of material that has been dented or
otherwise damaged; damage to the platen wiper can
result.
Moving parts can pinch or amputate fingers. When
the pump is operating and when raising or lowering
the ram, keep fingers and hands away from the pump
intake, platen, and lip of the drum.
