Stabil-TRAK™ System and Boom Interlock System
10.8 Model 8042, 10042, 10054 Legacy Rev. 10/03
b. LOCKED Mode
With the boom above 40° (1 or 4) and by activating one
or more of the functions (as follows), the Stabil-TRAK™
system is in the LOCKED MODE (2 or 5) and the rear
axle is locked so it is rigid with the frame. The Stabil-
TRAK™ light (3 or 6) will be ON when:
• Engaging the parking brake switch
• Placing the travel select lever in (N) NEUTRAL
• Depressing and holding the service brake pedal
The Model 10054 has an additional boom extend interlock
system. This system prevents the boom from being
extended beyond a point between the “E” and “F” boom
extend letters (approximately 40' [12 m]), unless both
outriggers have been lowered onto solid terrain.
Once this system has been activated, the vehicle will
automatically place the Stabil-TRAK™ system in the
LOCKED MODE. The system will remain in the LOCKED
MODE, until the boom has been retracted. (Refer to
Section 10.6, “Boom Extend Interlock System Operation
(10054 Only),” for more information.)
The frame sway control will function slower than normal
in this mode with or without the outriggers down.
c. SLOW PIVOT Mode
With the boom above 40° (7 or 10), the Stabil-TRAK™
system is now in the SLOW PIVOT MODE (8 or 11). In
this mode the rear axle is UNLOCKED and is allowed to
pivot, but will respond SLOWLY to changes in terrain. The
Stabil-TRAK™ light (9 or 12) will be OFF when:
• The parking brake switch is disengaged
• Placing the travel select lever in Forward or
Reverse
• The service brake pedal is disengaged
The frame sway control function will function normally in
this mode.
To check that the Stabil-TRAK™ System is functioning
properly, refer to Section 10.8, “Stabil-TRAK™ System
Test,” for the proper system function.
