[QUOTE="skidsteer.ca, post: 4128, member: 307"] Perry the two little green lights should wouk like this You start the engine both lights are off, you push button once and one green light comes on. This mode is for using a hydraulic cylinder on your aux front couplers the oil only flows intermittantly, and is controled by the “self centering” thumb switch on the rh steering lever. ie push the switch to the R with you thumb and your grapple attachment closes. Push the same switch to the left and your grapple attachment opens. The second mode. Push the button by the green light a second time, now both green lights should be on. Instead of using the thumb switch you now use the finger “trigger“ switch on the front side of the RH steering lever. Squeezing the trigger switch will cause the oil to flow contiuously until you squeeze the trigger a second time. This mode is used for a hoe attachment or brushcutter, something requireing continuos flow to opperate. Your loader appears to be stuck in the continuos mode as you always haveing this trouble When you start the engine the green lights should both be off. If they were on (aux hyd was in use) b4 you shut the machine off (and they would be on only if you pushed the button beside them, and you would only push this button because you wanted to use the “auxilary hydraulics” / “front quick couplers”) they should automatically go out every time the key is turned off. If they (one or both) are on when you start the engine and you never touched th button beside them then there is (likely) a problem with the switch or wiring. If thats the case, then the problem may not be dirt at all. with the key on, are one or both green lights on? If yes then go to the main hyd valve (the one the foot pedal linkages connect to) there will be a section for one foot pedal, a section for the other and a 3rd section for the aux hyd. This 3rd section will have a spool (round black thing, smaller then your fist) with 2 wires coming from it. One spool on each end. Gently remove the nut in the center and try to slide the coil (black thing) off the spool (metal rod in center that nut was attached to) the green lights indicate that one or of the spools is getting power so there should be a magnetic pull holding the coil on the spool, you slide it partially off and magnetic pull trys to put it back on. If your problem is electrical you can unplug the wires to each spool then the flow to the aux couplers should stop. If the problem is still there then it may be dirt (though im not sure why either green light should be on) If disconecting the spools does not work then remove your front aux couplers and get a hyd shop to make you a hyd hose to fit the end of the steel lines, or follow the steel lines up to the top/rear of the loader arm and disconect the 2 hoses there and buy a fitting to join them together. They should be a # 10 JIC male one each hose. So you would need a double # 10 female to join them. these are common hyd fittings that most hyd hose shops should have or buy a male and female couplers and a hyd hose to fit between them and plg them into the couplers to “loop” the aux hyd together (more $ but easy to insall or remove) after looping you aux hyd valve spool you should have eliminated this as a potential problem Ken [/QUOTE]
