Code 04 - Tilt Condition

Check For These Obvious Conditions First:
• If machine is on a tilt of more than 1.5° in either or both the X or Y direction, this is normal operation.
(DRIVE and LIFT UP are disabled when tilt is detected)
• Check if Ground Control Module is mounted securely to the mast support column.
STEP
1. Using a digital level check the actual level of the machines' resting surface in
both the X and the Y directions. Does surface check within machine specifi-
cation.
2. At the Ground Control Module, enter the programming mode (See Ground
Control Programming, Section-3 of Service Manual) and check the tilt sen-
sor X and Y readings. Are readings within machine specification?
3. Zero Tilt Sensor on a surface checked to within 0.0 degrees with a digital
level in both the X and Y directions. (See Ground Control Programming, Sec-
tion-3 of Service Manual).
NOTE: If frequent calibration of the internal Tilt Sensor is required, replace the Ground Control Module.
