10.4 STABIL-TRAK™ OPERATION
10.4.1 Understanding Stabil- TRAK™ S ystem
The following is a description of modes in the patented
Stabil-TRAK™
system. The vehicle may operate in any
one of the following modes.
a. Free Pivot Mode
Boom below 40° (5), Stabil-TRAK™ system is in FREE
PIVOT MODE (6). Rear axle is allowed to pivot freely.
Frame level control will function normally with or without
outriggers down. Stabil-TRAK indicator will be OFF (7).
b. Slow Pivot Mode
Boom above 40° (5), Stabil-TRAK™ system is now in
SLOW PIVOT MODE (8). In this mode, rear axle is
UNLOCKED and is allowed to pivot, but will respond
SLOWLY to changes in terrain. Stabil-TRAK™
indicator
(7) will be OFF when:
• Transmission is in gear
• Service brake is disengaged
Frame level control function will act normally in this mode.
c. Locked Mode
With boom above 40° (5) and by activating one or more
of functions (as follows), Stabil-TRAK™
system is in
LOCKED MODE and rear axle is locked so it is rigid with
frame. Stabil-TRAK™
indicator (7) will be ON when
• Engaging parking brake switch
• Placing transmission control lever in (N) Neutral
• Depressing and holding service brake pedal
Model 10054 has an additional boom extend interlock
system. This system prevents boom from being extended
beyond a point between “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, vehicle will
automatically place Stabil-TRAK™
system in LOCKED
MODE. System will remain in LOCKED MODE, until
boom has been retracted. (Refer to Section 10.6, “Boom
Extend Interlock System Operation (10054 Only)”, for
more information.)
Frame level control will function slower than normal in this
mode with or without the outriggers down.
