Installation on a Ram
(Stainless Steel Plates)
Installation
Reference letters and numbers in the text refer to Figs.
9–12 and the Parts Drawing on page 16.
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.
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.
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
set-up and operating instructions.
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. 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.
