SERVICE AND REPAIR

CALIBRATE LOAD

This machine has a pressure transducer fitted to the lift cylinder which allows the ECU to cal-
•
culate the platform load by comparing the lift pressure with load calibration curves stored in the
ECU.
LOAD CALIBRATION PROCEDURE
If "LEVEL" hasn't been calibrated, then follow the procedure (refer to page 3-17) to "CALIBRATE
LEVEL" first.
If "HEIGHT" hasn't been calibrated, then follow the procedure (refer to page 3-18) to "CALIBRATE
HEIGHT" first.
1. Place the machine on a firm level surface and level the platform.
2. Switch the machine to ground controls.
3. Press and hold "ESC" for 5 seconds until "#### MENU: HELP: PRESS ENTER" is dis-
played.
4. Scroll to "ACCESS LEVEL" and press "ENTER".

If the GP400 control module, either of the boom angle transducers or the lift
cylinder pressure transducers are replaced and/or moved, platform load
must be recalibrated using the procedure provided. Failure to do so could
result in serious injury or death.
