CHAPTER 2  INSTALLATION
Mounting Bracket
1. Make sure all switches on the 744E Sprayer Control are turned to
the “Off” position.
2. Determine the best location for the 744E Sprayer Control in the
vehicle cab according to the following guidelines:
• pressure gauge should be readily visible
• switches should be within easy reach
• controller bracket should rest on a at surface
• 12 volt DC power source must be accessible (maximum draw
10 amps)
3. Determine the proper routing for power cables and pressure tube:
• away from operators’ movement area
• away from moving parts
• away from sharp objects
4. Install the mounting bracket using ¼″ (6.4 mm) drill, machine
screws, nut, washers and lock washers as illustrated below. Attach
the control housing assembly to the mounting bracket using the
console adjusting knobs and washers.
Figure 5: Mounting bracket
Tube Assembly
Fluid leakage around the gauge indicates a poor connection or a
defective gauge.
NOTE: All cables and tubes must be placed in a way, so that they
cannot be snagged or pulled with the operator’s feet. Tubes
and cables must be routed around sharp metal objects, edges
and moving parts with enough slack so that they will not be
pulled apart when sharp turns are made.
Connection to Manifold
1. Connect 1/4″ NPT tting (K) to the manifold.
2. Connect the gauge elbow (A) to the 1/4″ NPT tting (K).
3. Locate the tubes on the TJ744 harness (N).
4. Remove the tube nuts (B) from the gauge elbow (A) and slide
the tubing through the nut. The threaded portion of the nut
should face its respective gauge elbow. The tube should protrude
approximately ½″ (1 cm) beyond the nut.
5. Insert the brass tube insert (C) into the end of the tube. This must
be used with the gauge elbow assembly.
6. Connect tube nut (B) to the gauge elbow (A).

Connection to 744E Console
1. Locate the gauge elbow (A) on the TJ744 console (M).
2. Remove the tube nuts (B) from the gauge elbow (A) and slide
the tubing through the nut. The threaded portion of the nut
should face its respective gauge elbow. The tube should protrude
approximately ½″ (1 cm) beyond the nut.
3. Insert the brass tube insert (C) into the end of the tube. This must
be used with the gauge elbow assembly.
4. Connect tube nut (B) to the gauge elbow (A).

CHAPTER 3  MAINTENANCE
Routine Procedures
Several routine procedures should be followed to help maintain the
744E Sprayer Control system.
1. Check all wires and connections for wear, damage and frayed ends
to prevent shorting out of the system.
2. Make sure that the mounting bracket for the 744E Sprayer Control
is mounted securely.
3. All connections and terminals should be free of corrosion.
4. The control unit is designed so that it may be removed, cleaned
and stored during periods of non-use to protect it from extreme
heat or cold.
5. The 744E Sprayer Control is NOT WATERPROOF. Do not immerse
the unit when cleaning.
6. Periodic ushing of the sprayer will help prevent clogging due to
residue buildup.
Removal of Control Unit
1. De-pressurize the system.
2. Uncouple the nylon pressure tube from outside the vehicle cab
and allow the liquid to drain. Uncouple the tube from the bottom of
the unit.
3. Disconnect the input power cable from the back of the unit.
4. Disconnect the output control cable from the back of the unit.
5. Loosen the triangular knobs on both sides of the unit and slide the
unit off of the bracket.
