system is active and functioning properly.
To test the function of the Stabil-TRAK™ system, read
the Stabil-TRAK™ System Test instructions and follow
Steps 1 through 9 of Section 10.4.2, “Stabil-TRAK™
System Test Procedures.”
10.4.1 Stabil-TRAK™ System Test
Instructions
• Test the Stabil-TRAK™ system with the machine
on a level surface.
• Remove any attachment from the quick attach
before performing the test.
• DO NOT extend the boom at any time during the
test. Perform the test with the boom fully retracted.
• DO NOT raise the boom above 60° for Steps 3-6.
• DO NOT raise the boom above 45° for Steps 7-9.
• Follow Steps 1 through 9 of the Stabil-TRAK™
system test procedure exactly as written.
Note: If the Stabil-TRAK™ light goes OFF and the front
left tire lowers to the ground at any time during Steps 4
through 7, the test was not performed properly or the
Stabil-TRAK™
system is not functioning properly.
Carefully repeat the steps starting with Step 1.
If the Stabil-TRAK™ light goes OFF and the front left tire
lowers to the ground consistently during Steps 4 through 7,
the Stabil-TRAK™ system is not functioning properly and
the test should be stopped immediately. If the Stabil-
TRAK™ system is not functioning properly, follow the
procedures in Section 10.5.2, “Stabil-TRAK™ Hydraulic
Circuit,” to repair the system.
Note: The front left tire off the ground during the test is a
visible indication that the stability system is in the locked
mode.
