Here is a company in Virginia that may be able to steer you in the right direction http://forestryconstruction.com/content/manufacturers

Check your oil pressure with a pressure gauge, you may have an oil pressure problem not just the sensor.

There is a safety device so the boom can not be operated unless sensors on the legs are confirming legs are all set

Check the solenoid

Disconnecting all electric+hydrolic+cooling and the engine is taken out through rear door

Could you be more specific in the syndrome?

There is a check valve on Ls for each user and one is open where the message from the lever is leaking out.

It bleeds itself, only if a ram has been disassembled you need to extend and retract the ram several times slowly without building up pressure. then you should be good to go

Yes through dipstick

Does it give you an error code when it jumps out of gear? Do you have the tech code to get into the display? if so try to recalibrate the transmission valves.

Check seat switch neutral safety switch power to main contactor does the contactor close?

This is an injector driver code. injector driver module has failed ECU failed injector shorted to battery voltage may need to reflash VSM

Try fuel filters and also make sure its not overheating. Coolant level, radiator plugged??

I would try putting lift hose on the down side and down hose on the lift side. If it lifts when you push the down control and does not go down when you use the lift control then it may be a spool problem. Always take care to control all forms of energy when removing hoses to prevent harm or *****. I'm not sure if the spool on your loader is pilot controlled or mechanical linkage?? If it is mechanical take a look at all linkage and make sure its moving correctly. If its. Pilot control then the issue may be there also. Good luck and be safe.

Almost always the fuel filters. If the filters have been changed and the air is removed from fuel system it may be the pump. There should be a primer bulb in line with the fuel hose coming from the tank. Give that a squeeze and it should get hard if you have fuel pressure. If the primer bulb collapses when the machine dies that means there is something inside the suction tube located inside the tank. I have had this happen many times. You have to remove the suction tube from the tank to clean it out. DO NOT BLOW AIR INTO THE LINE. Good luck.

If no hydraulics are operating then there may be a few things to look at. Check the hydraulic fluid level as drive and bucket controls are hydraulic based. The hydraulic pump is shaft driven by the hydrostatic pump. If the fluid level is not proper, this could cause symptoms. Air in the system is another factor but most systems are self purging.

There are filters in various points around the unit and are 40 micron. Main filter has s bypass should filter be clogged. However, the smaller filters do not. The hydraulic system stays at charge pressure and fluid flows through control valves until actuated. If a spool is stuck, it may be bypassing fluid not allowing pressure to build up. Should give a basic starting point to troubleshoot further.

If the pedal you are talking about is deadman switch, either FOD has rolled in under pedal and lodged orbit is time to get a replacement pedal

that code has something to do with the remote system ,its not working properly or its not communicating with it ,that is if you have it connected

try this forum and see if they can help you get this going? https://www.thecombineforum.com/forums/4-john-deere/1442-code-list-9610-a.html
