Echo Timberwolf chain/bar issues

[gentlemanfarmer]

I bought a new Echo Timberwolf last fall - I went to start for the first time this Spring. I did not start and run this thing in the farm supply store where I bought it, which was probably a mistake

The chainsaw starts with no issues, but I cannot get the chain to move at all. The sprocket moves when I remove the bar and chain, however, this thing will not turn and just starts smoking with the chain and bar back on. The chain does get stuck/pinched in certain places in the bar.

In this likely just an issue with the bar or am I missing a critical first step with getting this thing up and running?

Check that the chain and clutch sprocket are the same pitch,maybe it was assembled with the wrong bar and chain.I know you said the chain was not getting pinched at different places on the bar ,but what about around the sprocket on the nose of the bar.

Chain / clutch brake is likely engaged. That is the anti-kickback device. It is the plastic "paddle" looking bar-thing just in front of the top handle. If the chainsaw kicks back, the chain brake "paddle" hits your top hand and engages the chain brake. To disengage, pull it toward the rear of the saw. Your face may go a bit red when you figure out what you've done...

It is getting pinched in places, including at the end. The sprocket on the end does move though. Is there an easy way to loosen up the bar?

Thanks! I know that step! Luckily not the issue this time.

Did you take the bar and chain off? Inspect the drive links for damage. If the chain has burrs or other damage, it will lock up inside the bar's rails and not slide properly. With the chain off, does the bar tip rotate freely?

You could have something like a .050 bar with a .058 chain?
list numbers on bar and chain to see if matching

Make sure there are not any burrs on some of the drive links causing it to bind.File them down if necessary.Check the groove in the bar and see if it was damaged somehow.It may be too narrow in some spots causing the chain to bind.You could take a flathead screwdriver and open the groove some to allow the chain to slide freely.Just don’t open the groove up too much,try to keep it consistent with the rest of the bar.Again double check that the bar and chain are the same gauge such as .050,.058 etc.Hope this helps.Let us know what it ends up being.

If you had a .058 gauge chain in a .050 bar, that would cause your symptoms.

Could be excess paint in the groove.

Did the chain come in a box or was it already on the guide bar.

Need some pics of the chain to see what type it is and a pic of the bar. Wonder if it's a LP bar running a 72 style chain??? But not sure a LP bar would fit that mount. What size is the bar? If its 20" then that shouldn't be the issue.

Please ignore my previous post ,I did not see the other post before mine with similar information.

Already on

It appears i definitely have some burrs on the chain causing it to lock up

I think it’s definitely a chain issue - found some burrs and imperfections on some of the teeth. I may need to file down or replace

Good call on this. I did find some flecks of paint in there

 

[Brufab]

Wow that's crazy it has that big burr on it. Glad you were able to identify the issue.

Is the CS-590 TimberWolf a spur or rim sprocket?

 

[Chevboy0167]

Looks to be spur from the pic JQ. Personally, I don't think just paint in the bar rail would cause that kind of damage to the drivers.....
