Stabil-TRAK™ System and Boom Interlock System
10.6 BOOM EXTEND INTERLOCK
SYSTEM OPERATION (10054 ONLY)
The ultimate purpose of this system is to add an extra
measure of stability, allowing the boom to be extended to
its maximum limits. The boom extend interlock system
may operate in one of the two following modes:
10.6.1 Extend Interlock Mode
The EXTEND INTERLOCK MODE, limits boom
extension (4) to a point after letter "E" has appeared on
the side of the boom and before letter "F" appears. A
sensor in the boom will automatically STOP the boom
from extending past this point until the outriggers have
been lowered onto firm terrain.
The retract function will still operate normally in this
mode.
With the outriggers RAISED (5) and the boom inside of
the extension limit (4) the vehicle will function normally.
The Stabil-TRAK system will perform as designed.
10.6.2 Outrigger Interlock Mode
The OUTRIGGER INTERLOCK MODE, allows for full
boom extension (6) only as long as both outriggers (7)
have been lowered onto firm terrain (outriggers DOWN).
Once this condition is met, the boom is allowed to extend
to its full limits.
IMPORTANT: As an added measure of safety, ALWAYS
remember to shift the Travel Select Lever to the (N)
NEUTRAL position, move the neutral lock lever to
NEUTRAL LOCK position, and engage the park brake
when lowering the outriggers.
As the boom is extended past the “F” boom extend letter,
the vehicle will automatically place the Stabil-TRAK™
system in the LOCKED MODE. It will remain in this mode
until the boom has been retracted to a point where the
boom extend sensor is activated.
With the outrigger interlock engaged additional systems
are automatically activated which enhance the stability of
the vehicle:
• Stabil-TRAK is in the LOCKED Mode.
• Transmission has been DECLUTCHED.
• Parking brake is ENGAGED.
• Outrigger RAISE function is inoperable.
• Stabil-TRAK light will be ON (8)
Other effects you will experience while the outrigger
interlock is engaged:
• With Stabil-TRAK active, frame sway will be slower
than normal.
• Outriggers are still allowed to lower to adjust for any
changes in outrigger footing.
Not until the boom has been retracted past the extension
limit will any of these conditions change.
It is important that you regularly check that this system is
functioning properly. To check that the Stabil-TRAK™
System is functioning properly, refer to Section 10.8,
“Stabil-TRAK™ System Test,” for the proper system
function.
