Installation on a Ram
(Stainless Steel Plates)
Installation
Reference letters and numbers in the text refer to Figs.
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your fingers. When the pump is operating and when raising or lowering the ram, keep
your fingers and hands away from the priming piston and lip of the pail.
4.Connect a 965 mm (38 in.), 6.3 mm (1/4 in.) OD tube (F) from the ram’s air assist valve (G) to the elbow (H) on the wiper plate.
5.Refer to the separate ram and pump manuals for
Operating the Air Assist Valve Handle
The ram’s air assist valve (G) directs air under the wiper plate, making it easier to pull the plate out of the pail. For the air assist valve to function, you must open a passage for the air with the valve handle (J). Practice using the handle a few times, until you are familiar with its use.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5.
1.Relieve the pressure.
2.Install the wiper plate (A) onto the pump intake (B), with the wiper plate vent handle (C) facing the left of the ram. Secure by tightening the setscrews (17). See Fig. 9.
3.The wiper plate is supplied for use with 19 liter (5 gallon) straight sided pails, but it can be easily modified for use with tapered pails. See steps a and b
a.To use the wiper plate with tapered pails, the large spacer (8) must be removed. Work- ing from the bottom, use a screwdriver to pry the spacer loose. Work it upward so it is com- pletely above the flange (D) of the wiper plate. See Fig. 10. Next, by hand, angle the spacer and work it off the plate, pulling it down over the flange and bottom wipers (E). See Fig. 11. Save the spacer, as it is required for other applications.
b.To reinstall the spacer for use with a straight sided pail, first make sure the large diameter of the spacer (8) is facing down. Work the spacer up over the wiper plate by hand, so it is completely above the flange (D) of the wiper plate. See Fig. 11. Then, working from the top, use a screwdriver to position the spacer between the flange (D) and the wipers
(E). See Fig. 12.

WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5.
1.Stop the pump. Relieve the pressure.
2.To open a passage for air to get under the plate, rotate the handle (J) 45_ clockwise and pull it upward (it should travel about 13 mm [1/2 in.] up and down).
3.Turn the ram director valve to UP. Press the air assist valve (G), and hold it in until the plate clears the top of the pail.
4.To close the air passage, push the handle (J) down and rotate it 45_ counterclockwise to lock.
Maintenance
If the wiper plate does not come out of the pail easily when the pump is being raised, the air assist tube (F), elbow (H), or valve (J) may be plugged. A plugged valve prevents air from reaching the underside of the plate to assist in raising it from the pail.
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 5.
Relieve the pressure. Refer to the Parts Drawing on page 16 and disassemble the air assist valve (J) as shown. Clear the hose (F) and the elbow (H) in the wiper plate. Clean all parts of the valve, and reas- semble.
