Check the relay connections, they are pretty poor to be honest we recently removed ours pulled the female part of the spades from their position in the mount and crimped them up to make a firmer connection. In time we will probably replace the female part of the spades with better quality connections.

 

Hope that makes sense and would be one of my first areas to check, you can do it without taking to much apart by simply removing the cover for the relays held on with 2 butterfly nuts, then whilst the machine is running and the feed rollers not going forward wiggle the relays whilst having someone press the forward button, if it starts feeding that's your fault.

 

Otherwise call Timberwolf they are helpful and will point you in the right direction.

On my old TW I had a small piece of angle iron jammed on top of the relays to keep them snug.

 

Just replacing them is also a good start, easily available from motor factors.

Still you never know, he might still be in his workshop 3 years later scratching his chin.

Basically yes still here 3 years later scratching my chin ! 

I did get them working for a while . Relays was one of the problems ,

but there is a number of things causing the same symptoms . After it’s been running for a while the rollers just stop , killing and then restarting the engine seemed to get them going again for another 20 mins or so. Then same thing again! 

I put this problem down to the hydraulic oil because after it got upto temperature the rollers would stop and the chipper oil tank had gone below minimum And the oil was going into the other tank then overflowing . I changed the hyd oil recently and new filters and breather valves which seems to have cured the problem of the oil going into the other tank , however when I took the tanks off to clean them out I noticed there isn’t even an oil level sensor so that wasn’t the problem at all,  and still the forward roller doesn’t work again at all . Reverse still works, I’m just looking at it again today. 

Anyone know what the 3rd wire is for on safety cut out switch on the push bar ? 

The blue / brown wires make a circuit and when the button is pressed the circuit breaks . What’s the 3rd wire tho?
