We all know the Juno is a reliable little machine, but every once in a while, they need a little help. Here is a quick breakdown of the top issues you can probably solve yourself. With this guide, and maybe a little phone support, you can keep your machine running and save money.
All Junos use ultrasound sensors to follow the feed fence at the right distance. If your machine is drifting into or away from the fence, or alarms out with ultrasound alarms, check here first. Make sure there is no debris covering the sensor, that the black foam filter is intact, and that the height of the sensor is correct—especially if you have a neck rail. Sometimes through bumps and collisions, the sensor bracket is bent at an angle. If this happened to your Juno, just bend the bracket back so it faces directly at your headlocks or neck rail.
Castor Wheel When your Juno weaves back and forth during a feed push, fails to turn correctly, or can’t follow a strip, you could have a jammed castor wheel. If you find your castor is stuffed full of feed fibers and gunk, clean it out. With this wheel not turning or swiveling, the Juno really struggles to drive and turn accurately. Another castor problem can happen when your skirt is adjusted too low—so low that the castor is off the ground! When lowering your skirt, make sure not to overdo it and make your machine unreliable by accident.
Inductive Sensor (Metal Sensor) For the Juno 150, any time it starts to miss a reset strip or strip-follow, check the inductive sensor boot. If feed or an object gets under the Juno while driving, this boot gets lifted or twisted out of position. While there is an option in the Settings called Inductor Height to get this adjusted perfectly (call us), there is a quick and dirty method that works well. Get a 5mm Allen wrench to loosen and tighten the boot brackets, and adjust the boot to be square, level, and a finger-width off the ground.
Charger We often get calls for a Juno driving right past its charger. In many cases the charger breaker is off, the charger is flashing an error code, or the prongs have worn or bent so they no longer touch the Juno. Check the breaker and plug first and then make sure you have a green LED lit on your charger. When the Juno is charging, you should have both a green and orange LED. If both the LEDs are flashing, this is an error code. You can call us to find out what error you have, but in almost all cases it just needs to be reset by powering the charger off (until the LEDs die) and back on again. Your Juno could also be just missing the charger prongs. This is usually the cause when the problem is happening intermittently. Charger prongs wear and bend over time, so one fix is to power down the charger and bend them outward slightly to get reliable contact. If it still misses, we can tweak your route over the phone.
When to Call: Early & Often The single best thing you can do to solve simple problems yourself and save a call-out is take advantage of our phone support. Call early when you first have a problem so we can help point you in the right direction. Call often, so we can keep troubleshooting or you can decide to call us out. The earlier and more often you call, the sooner that feed is being pushed up to your hungry cows.
