Pole Saw

[ParadiseThinkersKY]

Hi all,
I own a Ryobi 40v pole saw, the expand-it edition, and I am experiencing some bouncing/jittering when I try to prune trees. I installed a new chain and thought it would be all good, but it's not.. the chain I had on previously never gave me this issue and I was cutting everything good! So my questions are, what do I need to do to correct this or what is wrong?

Also, does anyone have recommendations on sourcing replacement parts for all Ryobi outdoor tools? I live in the Cayman islands and can't access the link on the Ryobi site so I need an alternative, if available.

Thank you for your help!

Are you sure you have the chain fitted in the correct orientation?

Yup, everything is as it should be.. what are the possible problems if everything is done correctly?

Lots of things, different type and or make of chain, incorrect gauge, incorrect pitch, worn nose sprocket on bar, worn drive sprocket, worn bar rails, going from low kickback chain to a more aggressive style.

Chain and Guage are correct. They are the same as the first one I used. Bar used little, less than a year worth of usage, but possible. Experienced kick back when first using it and the chain slipped and damage the Guage (teeth?) So I replaced the chain immediately as it didn't run smoothly after reassembling it but possible damage to bar but other chains had no issues for good amount of usage, not sure about the "low kickback chain" as the chain was the same as the other.. I'll try the old chain, see how that goes and report back to you if the problem doesn't happen again. Do you do hypotheticals? If so, what if the old chain doesn't give me the shakes, what could that mean then?
New at this, I really appreciate your feedback and I can't find vids pinpointing any of this to me. Thanks

Take a phot of the drive sprocket at the end of the shaft that drives the chain. Old chain if worn and damaged will mate to a damaged sprocket (they both wore at the same rate) and the new chain will have full drivers that may not be meshing perfectly with a worn/damaged drive sprocket- but running the two together will damage the drivers of the new chain.

Is it just shacking when you go to cut with it or does it do it to just reving in up when it's not cutting

 

[Bob Hedgecutter]

So it is only shaking when the chain is loaded and working- may be meshing with the sprocket near enough under no load and out of sync once the chain is loaded.
Sounds like something is not right in the drive head- the sprocket, or the bearing that supports it.

 

[Bryan Newton]

That's what I'm thinking

The chain isn't gripping into the tree when I try to cut so it bounces/kickback. Brand-new chain too.

Can you show picture of chain and bar on the saw

Forgive the spanner, couldn't find a washer! When I pull/rotate the chain, it has a bit of tension on it but the tensioner isn't at it's max. When I rotated it at a slow speed by hand with the cover off, the chain would find a tough spot and I'd have to pull harder to make it rotate. When I pull harder/faster, it's better/no jam.

Let me know if this is good
