Over heating firewood processor

[Woodworks]

My little Farmi has taken to getting a little too hot when running. Handbook says to stop if the hydraulic oil gets to 80c. Had this happen on occasion in hot weather in the past but today was cool, overcast with a breezy and we still had to stop a few times to let it cool down. What could cause the overheating? 

 

Thanks

Were you just splitting, or cutting as well? I've noticed the oil temp go up when just using it as a splitter.

No it was cutting and splitting some fresh ash, chestnut, alder mix. Lovely easy stuff to cut and split. Yours was less prone to getting too hot than this one.

Do you regularly change the filters as spec. in the manual?

This . The smaller the the restriction that you force hydraulic oil through the hotter it becomes . Partially clogged filters have more restriction than clean ones .

Not changed it but took it off and gave it a visual inspection. Looks like new but did talk to Riko who said give it a clean with some petrol but they did not think that would be the cause.

It's really important to regularly change hydraulic filters even though they look spotless. Forget washing in petrol!

Microsopic particles of metal swarf build up and other contaminates that you cannot see.

 

Fair enough it's been an exceptional summer with all engine temperatures up, however for longevity I would be looking at fitting an oil cooler.

 

Not serious money but worth the investment if your keeping the machine long term, anyway you will have it for the next one.

Got a new one on the way so lets hope that is the cause of the problem. £750 for the oil cooler so that's not going to happen. Never overheats when working on my own as the loading time gives the machine a few moments to cool. Normally just a problem on a  few jobs in the summer with the right wood and a good helper.

Interfluid hydraulics Gunnislake - the whole lot > £200. ?

Now £200 is more like it! Is it bulky as there not a vast amount of spare space on a mobile processor
