Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
D are instructed to relieve the pressure,
D stop spraying/dispensing,
D check or service any of the system equipment,
D or install or clean the spray tip/nozzle.
1. Lock the gun/valve trigger safety.
2. Close the pump air bleed valve (required in your
system).
3. Shut off the main air bleed valve (required in your
system).
4. Unlock the gun/valve trigger safety.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Lock the gun/valve trigger safety.
7. Open the drain valve (required in your system)
and/or the pump bleeder valve, having a container
ready to catch the drainage.
8. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray tip/nozzle or hose is
completely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the tip guard retaining nut or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.

Installation on a Ram
(Carbon Steel or Aluminum Plates)
Installation
Reference letters and numbers in the text refer to Figs.
1–4 and the Parts Drawings on pages 14–15.
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 the 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 front
of the ram. Secure by tightening the setscrew (3).
See Fig. 1.
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.
b. To reinstall the spacer for use with a
straight sided pail, first make sure the large
diameter of the spacer (19) 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. 3. Then, working
from the top, use a screwdriver to position the
spacer between the flange (D) and the wipers
(E). See Fig. 4.
4. Connect a 610 mm (24 in.), 1/4 in. (6.3 mm) OD
nylon tube (F) with a 1/8 npt(f) fitting (H) from the
ram’s air assist tube fitting (G) to the air assist
check valve (21) on the wiper plate.
5. Refer to the separate ram and pump manuals for
set-up and operating instructions.
Maintenance
If the wiper plate does not come out of the pail easily
when the pump is being raised, the air assist tube (F),
fitting (H), and check valve (21) may be plugged. This
prevents air from reaching the underside of the plate to
assist in raising it from the pail.
WARNING
a. To use the wiper plate with tapered pails,
the large spacer (19) must be removed. Work-
ing from the bottom, use a screwdriver to pry
the spacer loose. Work it upward so it is completely above the flange (D) of the wiper plate.
See Fig. 2. Next, by hand, angle the spacer
and work it off the plate, pulling it down over
the flange and bottom wipers (E). See Fig. 3.
Save the spacer, as it is required for other
applications.

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
