WORK SAFELY!
Only a qualified service technician with proper training
should perform this installation. Follow all shop safety rules
when performing this installation.
PREPARATION
1. Place the pump in an area free of dirt and debris.
2. Disconnect negative battery cable from the battery.
3. Disconnect the 4 plugs from the receptacles on the
rear of the control box currently installed on the pump
(see Figure 2). Mark and tag the plugs for reference
when new control box is installed. Remove the fuse
from the rear of the control box and keep the nut and
washers. They will be used to reinstall the fuse on the
new control box.
4. Remove the existing control box as shown in Figure 2.
Keep the hex bolts, flat washers and lock nuts. They
will be used in the installation of the new control box.

1. Emergency Stop Button — Press emergency stop
button to stop pump in an emergency. Turn knob
counterclockwise to disengage the stop button.
2. Ignition Switch — Insert the ignition key here to start
the engine. Turn the key clockwise to the ON position,
then continue turning clockwise to the START position
and release. To stop the engine turn the key fully
counterclockwise to the STOP position.
3. Digital Readout Screen — Displays and monitors the

6. Remote Cable Connector — Insert the remote control
input cable into this connector.
7. Direction Control Switch — This 2-position switch
controls the direction of flow for any mix in the pump.
The leftmost position sets the pumping direction to
forward and the rightmost position sets the pumping
direction to reverse.
8. Pumping Control Switch — This 3-position switch
controls the pumping of the pump. The rightmost
position (REMOTE) is for use with the remote control
unit, the leftmost position (LOCAL) is for normal
pumping operation, and the center most position
(CENTER OFF) prevents pumping.

9. Cylinder Stroke Control Switch — This 2-position
switch controls the pumping function. The leftmost
position (AUTOMATIC) sets the pump to automatic
cycling. Set the switch to this position for normal pump
operation.
The rightmost position (JOG) changes the pump from
automatic to manual cycling. This allows the cylinders
to be manually cycled using the Manual Cylinder
Jogging Switch.
10. Manual Cylinder Jogging Switch — This 2-position
switch allows the operator to manually jog the cylinders
to assist in clearing material line packs and is used to
test pumping pressure.
The leftmost position jogs Cylinder “A” and the
rightmost position jogs Cylinder “B”.
11. Stroke Volume Control Switch — Increases or
decreases the number of strokes per minute of the
pump (not used on model LS60TD).
12. Accumulator Press ure Gau g e — This gauge
monitors the internal pressure of the Accumulator tank.
Normal internal pressure should read approximately
1750 PSI during pumping.
13. Main Pressure Gauge — This gauge monitors
the system pressure while pumping material. The
maximum pressure rating is 4400 PSI ± 50.
