Excessive chain juddering

Go up a file size in yr sharpening guide, I do this if I am cutting dead elm or other fractious stuff, it makes a tougher profile an reduces bite, which may suite you Sir, k

( if it's 5.2mm then use 5.5mm )

Comments thus far much appreciated. Based on some of those comments let me elaborate on condition of this saw.

I did indicate that saw was less than 6 mnths old, checked paper work and its actually less than 3 months, purchased 18/11/17. So effectively brand new saw and bar! The current chain is a new from 10th Jan, so less than 1 mnth old.

 

The issues started after the new current chain was installed. Now I do have another chain, purchased at same time as replacement, which I haven't tried yet. I was interested in getting other peoples perspective on the problems I'm experiencing in case I was missing something obvious or there were known issues with the type of chain I'm using, before I started swapping & changing stuff about.

 

Additionally, the chain was originally replaced following an unfortunate incident when the saw got trapped in the kerf of a cut on a dismantle. When the limb I was cutting fell away the saw got dragged away out of my hands and in the process twisted the links on the original chain. The chain was unusable and replaced, problems started. Have to admit I've perhaps taken the rakers down a bit more aggressively than necessary thinking this might be the issue, but from comments above this was probably the wrong course of action!!

 

I will be stripping the saw down today, and will more closely inspect the bar for any issues following the "chain kink" incident. Though a visual inspection at the time it did appear to be fine. So thanks again for everybody's input, but if you or anyone else has any additional input in light of the added information then please fire away.

 

Many thanks.

It's possible you've used a depth guage meter for the wrong size chain. Easily done. 5 our so file strokes on each tooth and see if it's better. That should rule  it out.

I hope it's the chain.

 

If it's not you might have Parkinsons.

It's worth noting that the chain usually shipped with the echo is a 91px which is smoother cutting due to the extra safety ramps compared to the 91vxl. So if you have also taken the depth gauge down a bit on the vxl it will account for the increased judder and jamming. 

 

Because it is more aggressive we sell a lot more of the vxl.

Hi I had the same complaint after replacing the chain on my 360TES too.    It was so bad i took the chain back to the local dealer and complained and they swapped it for a different spec. chain which solved the problem.  It was dangerous in my opinion.  When i mentioned it on here a 2/3 years ago another Arbtalk member replied by saying 'i bet that chain is a blah blah blah' and when i checked the box it had come in he was bang on the money!  He explained to me that it was indeed too aggressive in his opinion and said i shud replace it asap.

Had the same issues

Filed off the back of the cutter sloping it down, and it's not so bad. Never bought anymore of them.
