8. Using the switch dust cover and the locknut in
combination, position the brake switch so the Stabil-
TRAK dash light comes ON at the 150 ±50 psi
(10,3 ±3,4 bar) brake pressure.
9. Repeat steps 6 through 8 until the Stabil-TRAK dash
light comes ON at 150 ±50 psi (10,3 ±3,4 bar) brake
pressure.
10. After the required pressure is achieved, use a
wrench and fully tighten the locknut against the
service brake switch bracket.
In order to test the switch for proper operation, the boom
must be raised above the 40° position, the parking brake
switch must be in the OFF position and the machine must
be in a forward or reverse gear mode. Proper operation
of the switch will activate the Stabil-TRAK dash panel
indicator. If the Stabil-TRAK indicator does not activate
when all conditions are met, the boom angle sensor must
be adjusted. Refer to Section 9.10.6, c. “Boom Angle
Sensor Installation.”
11. Shut off the engine.

c. Boom Angle Sensor Installation
1. Install boom angle sensor through outside of boom
frame.
2. Install locknut onto sensor.
3. Measure the clearance between the sensor and
frame, and adjust sensor distance (15) to 0.120”
(3,05 mm) and tighten locknut.
4. Properly connect the battery.
