Forst ST6 starting issue

[Thesnarlingbadger]

Hi all,

 

I’ve have an issue with my ST6 for the past few months and can’t seem to find the route of the cause.

 

The chipper starts from cold fine and generally works fine except on big jobs when it’s running flat out. The problem is if it’s been going 10 to the dozen and then we turn it off for a minute to let brash build up again then try and start it it won’t start. We leave in for half an hour or so and away she goes.

 

We have been getting by with the issue but I’m just a little worried as the commercial side of things is getting more and more and the old girl is doing harder days and a half hour stop on a big job a couple of times a day can be a right pain in the backside.

 

I have checked the coolant levels which are all fine. The fuel seems to be getting through the filters to the engine alright. The earth cable seem alright but every now and then I file the metal down to make sure it has a good connection. The starter motor is engaging but the machine isn’t not taking off.

 

I’m leaning towards it being and electrical issue somewhere but it’s annoying because it only does it when it’s been running for a while.

 

Any ideas guys? Thanks in advance [emoji106]

Stop solenoid? Does it turn over? Do you get white smoke out or nothing from the exhaust

YeH it turns over just doesn’t kick in. Yeah we tend to get white smoke from the exhaust when it starts up.

Fuel stop solenoid not returning look at the injector pump

Similar problem on my outfront Kubota, Fuel stop solenoid sticking needing a prod from my finger. Still does it sometimes but no bother.

Wicket thanks guys. I’ll take a look at it tomorrow on the job. Arbtalk to the rescue once again [emoji106]

If this was a GreenMech then I would suggest removing the small wire from the starter motor solenoid and going through the start procedure. With the wire disconnected you should be able to hear the fuel solenoid click in as the engine won't be cranking over.

If you get stuck, we are a chipper dealer and only based down the road in Devizes. We could look at the issue for you.

 

Thanks.
