January 2012Section 4 • Repair Procedures4 - 10 GS-30 • GS-32 • GS-46 • GS-47 Part No. 228901GROUND CONTROLS2-4Level SensorsThe Electronic Control Module (ECM) isprogrammed to deactivate the lift and drivefunctions and activate an alarm when a signal isreceived from the level sensor.The tilt alarm sounds when the incline of thechassis exceeds 1.5° to the side and 3° to the frontor rear.How to Install and Calibrate the1.5° Level SensorTip-over hazard. Failure to installor calibrate the level sensor asinstructed will compromisemachine stability and cause themachine to tip over, resulting indeath or serious injury. Do notinstall or calibrate the level sensorother than specified in thisprocedure.1 Move the machine to an area that has a firm,level surface and is free of obstructions.2 Remove the platform controls from the platform.3 Turn the key switch to platform control and pullout the red Emergency Stop button to the onposition at both the ground and platformcontrols.4 Raise the platform 7 to 8 feet / 2.1 to 2.4 m.5 Lift the safety arm, move it to the center of thescissor arm and rotate down to a verticalposition.6 Lower the platform onto the safety arm.Crushing hazard. Keep handsclear of the safety arm whenlowering the platform.If you are not installing a new level sensor,proceed to step 15.7 Turn the key switch to the off position and pushin the red Emergency Stop button to the offposition at the ground controls.8 Tag and disconnect the level sensor wireharness from the chassis wire harness.Note: The wire harness connection is located nextto the level sensor, on top of the chassis at thesteer end of the machine.9 Remove the level sensor retaining fasteners.Remove the level sensor from the machine.10 Tag and disconnect the level sensor wires fromthe level sensor connector plug.11 Securely install the wires of the new levelsensor into the level sensor connector plug.12 Place the new level sensor onto the levelsensor mount bracket with the "X" on the levelsensor base closest to the long side of the levelsensor mount, and the "Y" on the level sensorbase closest to the short side of the levelsensor mount.Tip-over hazard. The level sensormust be installed with the "X" onthe level sensor base closest tothe long side of the tilt level sensorbox, and the "Y" on the levelsensor base closest to the shortside of the tilt level sensor box.Failure to install the level sensoras instructed, could result in themachine tipping over, causingdeath or serious injury.
