TW230 feed roller problems and hydraulic oil

[vdubber79]

Hi, recently bought a 2003 TW75 230H tracked chipper and often if the rollers get jammed/ you stop them / or move the chipper and go to restart the blades they won't go forward , the backwards button works fine but forward won't, doesn't seem to be the bar switch I've tried messing with that when it does the problem, only way to get it to work again is to drop revs, turn off the engine restart and pull up revs again, this seems to always do the trick but it's a real pain in the ass! Where exactly is the relay that some are talking about .? It started doing it today and seemed to do it more often as the day went on . Also

what hydraulic oil do these old chippers take ? I assume ISO 32 And

does anyone know where I can buy or download the manual for this model

Many thanks

Hello Neil

 

I would suggest involving an authorised Timberwolf dealership or auto electrician to check the circuitry on the roller issue.

A manual has been emailed to you, hope its useful.

 

32 grade hydraulic oil is used on your machine.

Ok I will do that, I am a vehicle engineer myself and familiar with electronic systems it's just these machines are new to me in terms of maintaining, although I have used them extensively this is the first one I've owned. I will check the wiring and relays and if I have no luck I will have to find my nearest dealership many thanks for your help
