Step 9:

exactly 45°
, move the range select lever to (3) THIRD gear.
b. Move the travel select lever to (F) FORWARD.
c. Release the service brake pedal to deactivate the Stabil-TRAK
system. The Stabil-TRAK Lock light should go OFF. The Stabil-
TRAK Slow Pivot light should come ON.
d. Slowly drive the vehicle forward against the block to stop the
vehicle from moving forward.
e. With the front left tire against the block, frame sway the vehicle
no more than 5°
to the left.
f. Check that the front left tire remains on the ground. It is normal
for the front left tire to raise slightly when swaying to the left, but
the tire should immediately lower when the frame sway function
is stopped.
g. Frame sway the vehicle back to 0° and pause briefly.
h. Frame sway the vehicle no more than 5°
to the right.
i. Check that the front right tire remains on the ground. It is nor-
mal for the front right tire to raise slightly when swaying to the
right, but the tire should immediately lower when the frame
sway function is stopped.
j. Frame sway the vehicle back to 0°.
k. Depress the service brake pedal.
l. Shift the travel select lever to (N) NEUTRAL.
m. Lower the boom.
If steps 1 through 9 prove positive, the Stabil-TRAK system is functioning
properly and the vehicle can be returned to service. If any of these steps
indicate that the Stabil-TRAK system is not functioning properly, contact
your local JLG Authorized Service Center (ASC) immediately to repair the
system.
