SkyTrak 8042 Service Manual - Manual (Page 848)

10.7 Model 8042, 10042, 10054 Legacy Rev. 10/03
Stabil-TRAK™ System and Boom Interlock System
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 and apply the park brake. 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been retracted.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.)
Note: On Model 10042, the position of the outriggers
will not effect the described operation of the frame sway
in any of the following modes.
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
With the boom below 40° (6 or 9), the Stabil-TRAK™
system is in the FREE PIVOT MODE (7 or 10) and the
rear axle is allowed to pivot freely. The frame sway control
will function normally with or without the outriggers down.
The Stabil-TRAK light will be OFF (8 or 11).
