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 flat 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.

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 fitting
(K)
to the manifold.
2. Connect the gauge elbow
(A)
to the 1/4″ NPT fitting
(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)
.
