4. Once the leveling jacks make contact with the ground surface, there will be up to
a 5 second delay before the actual auto leveling begins.
Note: Due to varying ground conditions, there may be several delays between
machine level corrections. Be sure ample time is allowed for all leveling ad-
justments to be completed.
5. Continue to engage the leveling jacks until the extend jacks LED stops blinking
and is lit solid.
Note: The level adjustment of the machine may still be improved.
Manual Level Adjustment (Trim), page
Note: If a 2/5 flash code appears through the system fault light at the platform
control station, the machine is unable to level. Reposition and try again.
6. To retract leveling jacks, press leveling jacks button and move the controller
backward until jacks are fully retracted.
Note: There is a limit switch that senses when all four cylinders are fully retracted
and this will light up the leveling jacks retracted LED on the platform control
station.
The arm stack tilt sensor and the rotary angle (elevation) sensor work in con-
junction to determine the machine is stowed. Failure of any of these sensors
will prevent leveling jacks operation.
3.11.3 Manual Level Adjustment (Trim)
Note: There is an override feature on the leveling jack system that allows the operator
to adjust (trim) the level of the machine to the left or right when the platform is
completely lowered. Use the following instructions to adjust the level of the
machine.
1. With the machine in the stowed position turn the power on, start machine, and
engage Leveling Jacks function.
2. To adjust (trim) the machine to the right, activate the steer switch on the top of
the controller to the right until the desired position is reached.
3. To adjust (trim) the machine to the left, activate the steer switch on the top of the
controller to the left until the desired position is reached.
