Dead Wood stuck in rollers Jensen A528

[Sussex Groundie]

Hi,

 

Just acquired this chipper

 

Wonder if anyone has a good idea how to free up this piece of dead wood I have stuck the rollers in a Jensen A528. The engine stopped whist chipping this 6ft branch before I could reverse it.

 

Can I release the tension on the rollers or manually reverse them?

 

Is it a case of a felling lever to hold the rollers open and grab the wood out?

 

Hold the rollers open a bit and use a pole saw to destroy the wood?

 

 

Many thanks

I dont no about jensens but with my tw if this happens you take both springs off the rollers and lift the top roller and then pull the object out. Its abit odd that getting stuck though it looks a tiny branch compared to what you could put through, are you sure nothing is jammed in the flywheel?

Open the top, release the springs then leaver the wood back out.

Happens occasionaly on our jensen. More often than not it happens with dull blades.

Thanks guys for your advice

 

Will give it a go, did not like the idea of my fingers getting stuck in the rollers as they snapped shut!

Take the drive belts off and start engine, pull bars into reverse! Then fix the no stress device!

Looking at the picture something untoward has happened to the top roller which is probably your first point of interest.

looks like what happens occasionally with the TW,bit of a noggin occasionally jams into the roller races jamming them up as james said,pull the top roller up and hold it up with a bar and carfully slide the offending branch out

upon closer inspection of the picture,looks like a bearing may of gone astray in the top roller assembely, judging by the odd angle of that feed roller :scared1:

I think the angle of the top roller is normal . Ours pivots up more one side than the other . I think the anti stress device has cut in early maybe the blades are blunt and/or the feed was too high . Have you tried restarting the engine . If you start it on half throttle it should not try to feed in or out . I suppose the safety bar is not pushed right in stopping the feed ? bit obvious but just a thought . If it starts put it to full throttle and revers the feed and it should spit it out . Some times the feed rate dial vibrates round to zero and nothing hap[pens .. outside chance it could be that .

It is a Jensen. Their top roller can "waggle" as it is on a UJ with shaft drive to a gearbox which drives both rollers with one hydraulic motor. It is supposed to aid feeding awkward material. Plus the roller rises up in an arc instead of parrallel.
