signing a system to suit your particular needs.
Pump Location and Set-Up
1. Place the unit on a hard, level surface. Check that
the unit is level in all directions. Refer to Dimen-
sions on page 28 to ensure that there is sufficient
overhead clearance for the pump when the ram is
fully raised. Leave room on both sides so the air
regulators will be easily accessible.
2. Read the section System Components and
Accessories on page 9. Connect an air supply
hose to the 1/4 npt(f) main air inlet fitting (57). See
Fig. 2.
3. Unpack the wiper plate (P). Back out the screws
(302) so they will clear the pump intake housing
(11). Raise the ram by setting the ram director
valve switch (36) to the UP position and increasing
the setting of the ram air regulator (27b).
4. Place the wiper plate (P) on a 2 in. thick x 4 in.
wide block of wood. Center the wiper plate and the
wood block on the base, under the pump intake
housing (11).
5. Set the ram air regulator (27b) to zero. Set the ram
director valve switch (36) to the DOWN position.
As the ram unit slowly falls, guide the pump intake
housing (11) into the wiper plate (P).
6. Set the ram air regulator (27b) to 0.07 MPa, 0.7
bar (10 psi). Push down on the pump to install the
wiper plate (P) onto the intake housing (11). Se-
cure the wiper plate to the pump with the two
screws (302).
7. Connect the 660 mm (26 in.) air line tube (76) from
the connector (37) at the air assist valve (18) to
the connector (310) at the wiper plate (P). Refer to
Connecting and Disconnecting Tubes.
Connecting and Disconnecting Tubes
Connection
1. Grasp the tube, then slowly push it straight into the
fitting until it stops.
2. Be sure that the tube is securely connected, and
will not pull out when air pressure is applied. To
check, pull back gently on the tube to ensure that it
will not pull out.
Disconnection
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
1. Relieve the pressure.
2. Push evenly on the fitting’s red release button.
3. While holding the release button in, pull the tube
out of the fitting.
4. To reuse the tubing, cut off the previously connec-
tion portion at 90_, being careful not to damage
the outer diameter of the tube. Use of a tube cutter
is recommended. The fitting will leak if the tubing is
not cut at 90_.

System Accessories (See Fig. 2)
WARNING
Two required safety devices are supplied with your
pump: a bleed-type master air valve (8) and a
pump bleeder valve (25). These devices help
reduce the risk of serious injury, including splashing
in the eyes or on the skin, and injury from moving
parts if you are adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. The valve is located close to the
pump, downstream from the pump air regulator.
The pump bleeder valve assists in relieving fluid
pressure in the displacement pump, hose, and
dispensing valve. Triggering the dispensing valve to
relieve pressure may not be sufficient.
Supplied Components
The following components are supplied with your
pump.
DThe bleed-type master air valve (8) is supplied
with your system to relieve air trapped between it
and the air motor when the valve is closed (see the
WARNING above).
DThe pump air regulator (27a) controls pump
speed and outlet pressure by adjusting the air
pressure to the pump. The regulator is located
upstream from the bleed-type master air valve.
DThe ram air regulator (27b) controls ram speed by
adjusting the air pressure to the ram, and also
controls the pressure exerted by the wiper plate on
the fluid.
DThe pump bleeder valve (25) is supplied in your
system to relieve fluid pressure in the displacement
pump, hose, and dispensing valve (see the WARN-
ING at left). Be sure the drain hole in the valve is
pointing down. This valve is also used to bleed air
from the pump when priming.
Air Line
Connect an air supply hose to the 1/4 npt(f) main air
inlet fitting (57). Install an air line filter and lubricator in
the main air line. In the main air line, upstream from all
other air line accessories, install a second bleed-type
master air valve to shut off all air to the system and to
isolate the accessories for servicing.
Fluid Line
Connect a fluid hose to the fluid outlet fitting (28).
Connect a suitable dispensing valve to the free end of
the hose.

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acci-
dentally. To reduce the risk of an injury from acci-
dental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Proce-
dure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray nozzle.
1. Shut off the dispensing valve.
2. Shut off the bleed-type master air valve (required
in your system), on the main air line.
3. Close the bleed-type master air valve (supplied
with your pump).
4. Trigger the dispensing valve to relieve pressure.
If you suspect that the dispensing valve, nozzle, or
hose is completely clogged, or that pressure has not
been fully relieved after following the steps above, very
slowly open the pump bleeder valve, having a contain-
er ready to catch the drainage. Leave the pump bleed-
er valve open until you are ready to dispense again.
Very slowly loosen the hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the nozzle or hose.
WARNING
Keep hands and fingers away from the priming
piston and pump intake during operation and
whenever the pump is charged with air. During
operation, the priming piston extends beyond the
intake housing to pull material into the pump, and
can severely injure or amputate a hand or finger
caught between it and the intake housing. Always
follow the Pressure Relief Procedure at left
before clearing, cleaning, flushing, or servicing any
part of the pump.
The air motor piston and fluid piston (located inside
the air motor cylinder and coupling) also move
when air is supplied to the motor. Do not place your
hand or fingers into the air motor coupling cavity
while the pump is operating.
As the ram is raised and lowered, the wiper plate,
ram tubes, and pump mounting bracket move. To
reduce the risk of pinching or amputation of fingers,
keep you hands away from the wiper plate, lip of
the fluid can, pump bracket, and ram tubes while
the pump is operating.
To reduce the risk of serious injury and damage to
equipment, do not shut off the air supply to the ram
when the ram is raised. Doing so will cause the
pump to fall uncontrolled to the bottom.
