Having problems with your PC Desktops ?

Posted by iupholster on Mar 03, 2009 I have a hunter J111 alignment machine. When I go to set castor and you get to the screen that shows all four wheels are lit up green and even numbers then when you are supposed to turn left as soon as you do then the left front sensor starts blinking the red fault arrow and will not change, If you turn the wheels back to the front you get the all green lights and numbers back. If you stick your hand in the IR beam it takes the numbers from 150 down to 30


Answers :

Remove and clean and refit the sensor and try if still the same problem.then a manufactures needs to be called for service and replacement.
That is the isr sensor moved or out of range, you need to call manufacturer.
