There seems to be intermittent connectivity on the forward rollers kicking in which is the big half spherical black button. If you hold the button down for 20-30seconds it seems to understand. Then maybe it will take rollers forward on first press. Any help would be much appreciated. It doesn’t seem like a bad connection to me but I could be wrong.

I had a similar problem on mine ,turned out to be the solenoid valve ,not help by the plug attached to it,so worth checking no water has got in that connector ,

As mentioned,  it could be the solenoid valve or the bottom coil on the valve for infeed ?

This valve is mounted by the indexing lever for the turntable  , it has two coils , both with a square Herschmann plug connected to them.

I would suggest undoing the screw that holds each plug on and swapping the plugs over then run the chipper at maximum revs , press the palm switch and see if , by doing this the rollers will feed in reverse ? If so then I would suspect that the bottom coil is faulty. You can confirm this by pulling the red bar for reverse to see if the rollers will now feed forwards  ? If they don't instantly work then this would confirm a coil failure.

Many thanks. I’m flat out and it’s just getting me by. I’ll give it a good inspection with your helpful advice on a quieter day or day off. Seems everything boils down to a faulty solenoid 😅. Are the parts cheap and easily sourced please? 

[Jase hutch]

The parts should be in stock , the coil is reasonably priced but the armature kit if needed is quite pricey (part of the valve the coil sits over), but still a lot cheaper than a complete new valve assembly.

Just a quick update on the forward roller problem. As always I ought to have started on the easier fix options first. It was the Hirschmann plug that connects to the Vickers solenoid valve that was faulty. My auto electrician performed a quick fix and hey presto forward motion. Jason Hutch from GreenMech kindly sent me a pair of new Hirschmann plugs which will be fitted this week 👌🏼
