The following describes the three basic modes of the
patented Stabil-TRAK™ system. The vehicle may
operate in any one of the following three modes.
a. Free Pivot Mode (Fig. 10-6)
With the boom below 40°, the Stabil-TRAK™ system is in
the FREE PIVOT MODE and the rear axle is allowed to
pivot freely. The frame sway control will function normally.

b. Locked Mode (Fig. 10-7)
With the boom above 40° and by activating one or more
of the functions (as follows), the Stabil-TRAK™ system is
in the LOCKED MODE and the rear axle is locked so it is
rigid with the frame. The Stabil-TRAK™ light will be ON:
• Engaging the parking brake switch
• Placing the travel select lever in (N) NEUTRAL
• Depressing and holding the Service Brake with brake
pressure greater than 150 ±50 psi (10,3 ±3,4 bar)
The frame sway control will function slower than normal
in this mode.
