The Tilt Sensor has three wires; red-power (12v in),
black-ground, white-output (12v out). To verify the
sensor is working properly there is an LED on the
bottom of the sensor that lights up when the sensor is
out of level.
1. Check tires for proper pressure.
2. Place machine on firm level surface ± 1/4°.
3. Use Inclinometer to ensure that the front and rear
the chassis are level within ± 1/4°.
4. Adjust the three leveling locknuts until the bubble
is centered in the circle on the bubble level.
5. Elevate the platform until the down limit switch
opens and push the tilt sensor base to test the
alarm circuit. Alarm should sound.
