the Ram.
2. Attach kit to Ram using (5) Button Head Screws (see gure
7, page 5).
3. Remove the coil hose from the Lock-out Valve on the
Ram.
4. Attach the coil hose to the Air Supply Outlet (port#2) on
the low level cuto kit. Other end of coil hose should be
connected to pump air motor.
5. Attach the (4) Connector to the Lock-out Valve where the
coil hose was attached.
6. Connect the (9) Tubing to the (4) Connector.
7. Connect the other end of the (9) Tubing to the (2) Male
Elbow at the Air Supply Inlet (port #1) on the low level
cuto kit.
8. Attach the (15) Lever Rod to the (16) Limit Valve Assem-
bly. Set the (15) Lever Rod to about 30° from horizontal.
9. Attach the (10) Clamp and (7) Switch Plate to the piston
rod of the Ram. Locate the (10) Clamp by raising the Ram
2 inches o the plate and set a clearance of 1/4 inch be-
tween the (7) Switch Plate and (15) Lever Rod and tighten
the clamp.
10. Adjustment of the (15) Lever Rod and (7) Switch Plate
may be needed achieve the desired Ram position to turn-
o the pump.
11. Lower the Ram to actuate the (16) Limit Valve.
12. Test the setting by turning on the air supply to the as-
sembly. The air motor should remain o.
CAUTION
When the Ram is raised and the (15) Lever
Rod disengages from the (7) Switch Plate, the air mo-
tor will start.
13. To test the operation:
a. Set supply pressure to air motor @ 20 psi (1.4 bar)
maximum.
b. Raise the Ram until the motor starts.
c. DO NOT RUN THE PUMP DRY.
14. Turn o the air supply to the air motor until you are ready
for the pump to run.
67502 KIT INSTALLATION ON RAM
This kit is mounted on the Ram head using the (23) Cap
Screws that are included with the Kit (see gure 8, page 6).
1. Remove the Cap Screws (96702170) and Washer (96756)
that are on the Ram. (Only needed on models
SP0443X2XXXXXXXX and NP322XX4XR7-XX)
2. Attach Low Level Cuto assembly to upper bolt pattern
of Ram Head (Ref PN 97543-1 on Ram Assembly) using
(23) Cap Screws, (24) Washers, (26) Lock Washers, and (27)
Nuts (see gure 8, page 6).
3. Remove hose from elbow fitting on Lock-out Valve on
Ram. Install Hose into elbow tting in Air Supply Outlet
(port#2) on the low level cuto kit.
4. Install one end of (9) Tubing into elbow tting on Lock-
out Valve on Ram and install the other end in elbow t-
ting in Air Supply Inlet (port#1) on the low level cuto kit.
5. Attach the (15) Lever Rod to the (16) Limit Valve Assem-
bly. Locate the (15) Lever Rod by raising the Ram 2 inches
o the plate and set a clearance of 1/4 inch between the
(15) Lever Rod and Cap 96752 on Ram.
6. Additional adjustment may be made by loosening (11)
Nut and (18) Socket Head Cap Screw and moving (16)
Limit Valve up or down.
7. Adjustment of the (15) Lever Rod and (16) Limit Valve
may be needed achieve the desired Ram position to turn-
o the pump.
8. Lower the Ram to actuate the (16) Limit Valve.
9. Test the setting by turning on the air supply to the as-
sembly. The air motor should remain o.
CAUTION
When the Ram is raised and the (15) Lever
Rod disengages from the Cap 96752 on Ram, the air
motor will start.
10. To test the operation:
a. Set supply pressure to air motor @ 20 psi (1.4 bar)
maximum.
b. Raise the Ram until the motor starts.
c. DO NOT RUN THE PUMP DRY.
11.Turn o the air supply to the air motor until you are ready
for the pump to run.
OPERATION
1. Turn o the air supply to the pump.
2. Raise the Ram and place a drum of material into position.
3. Lower the Ram and, when ready, turn on the air supply to
the pump.
4. As the material is consumed and the Ram lowers, the (15)
Lever Rod will engage the (7) Switch Plate or Cap 96752,
switching the (16) Limit Valve, removing the air single
from port #3 to port #2 and exhausting port #2 to atmo-
sphere thru port #1.
5. When the pressure from port #2 exhausts, (1) Valve shifts
and removes the air supply to the pump, turning the
pump o.
6. Before raising the Ram, turn off the air supply to the
pump to prevent the pump from starting.
7. The position of (15) Lever Rod and (16) Limit Valve will
determine when the pump shuts off, but does not
control the Ram.
8. Caution should be used when lowering the Ram to
prevent damage to (16) Limit Valve.
