My Ryobi 10532 chainsaw chain will not turn. The chain lock is off, it is a new chain. I replaced the old chain as it caught in a stump and stopped turning

Also make sure your chain brake to reset.

I get asked this question a lot , im gonna have to make a video on this subject someday .
but here:
1st ck your oil viscosity/SAE it should be 30 and say bar/chain oil
next dump out entire oil tank and wash out with kerosene (you'd be surprised what I seen come out)
then remove bar and chain , locate oil outlet it's in body of saw near adjustment screw , use a small can of air to blow in this port softly , use a touch more of kero to clean this all out , refill tank with proper oil !!!! and run saw (no need to put bar/chain back on yet ) might take several minutes but oil should start to flow out hole !! stop saw and reinstall bar/chain then run again .. fixed !! if no oil comes out ever your oil pump is gonna need some fixing

for a low cost oil I use filtered used motor oil cut down with a dab of kerosene

When the chain comes off it will damage the drive links ( burr the sides ) if the burrs are not removed the chain will be tight in the bar grove and stop it moving, you need to file the damaged drive links, or replace the chain

As it is a new machine, you should return it for warranty repair or exchange. Make sure that the electricity source will power a working lamp. Good luck!

Look at eReplacementParts.com and the parts diagrams.

If you need more help come back.Post / thumbs / testimonial are welcome!

Take the old chain to a servicing saw dealer that can cut and make up one to fit nearly any saw made. Plus, they will usually give you good tips on maintaining the new chain as well. Hope this helps!

Fuel/Oil Mixture

1. Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
2. Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few months. Anything over 6 months old use up in a 4 cycle engine. HTH

RYOBI----- with the motor running at high revs the chain stops indicates that the sprocket behind the centrifugal clutch is worn out or the centrifugal clutch itself ,or the clutch shoes are worn out the way to tell is to remove the bar and chain and have alook where the chain was conected to the saw, i think you will see the sprocket is buggered and as that is attatched to the clutch drum that will have to be replaced along with clutch springs and shoes, i think you have been running the chain a bit too loose or not running it at realy high revs ,which is what they are designed to do ,cme back to me if you feel the need

Remove the recoil cap cut the knot of the old cord off pull out the string. Cut a new cord the same length thread it in and knot it . rewind the spool until the cord in the spool. fish the cord out of the pull hole and tie on the pull handle
