If the engine of your Ryobi Chainsaw starts but the chain isn't rotating, first, make sure the chain brake is released. If the chain brake is not engaged, the chain tension may be too tight. Also, the guide bar and chain assembly may be incorrectly assembled. Refer to Replacing the Guide Bar and Chain in the Maintenance section of this manual. Inspect the guide bar and chain for damage. Finally, the drive sprocket teeth may be damaged, in which case you should contact an authorised service centre for drive sprocket replacement.

Why is my Ryobi RCS4246B Chainsaw bar and chain running hot and smoking?

If the bar and chain on your Ryobi Chainsaw are running hot and smoking, there are several potential causes. First, ensure the chain lubricant tank is full; it should be filled each time you fill the fuel tank. Another cause might be that the chain tension is too tight. Also, the oiler may not be functioning properly. To check, run the saw at half throttle for 30 to 45 seconds, then stop it and see if lubricant is dripping from the guide bar. If there's no lubricant, contact an authorised service centre.
