Why is my Ryobi Chainsaw bar and chain running hot and smoking?
- H
  hillwilliamAug 1, 2025
  If the Ryobi Chainsaw's bar and chain are running hot and smoking, it could be due to several reasons. First, ensure the chain lubricant tank is full, refilling it each time you fill the fuel tank. Next, check the chain tension and adjust it according to the manual's instructions. Then, run the chainsaw at half throttle for 30-45 seconds, stop, and check if lubricant is dripping from the guide bar. If there's no lubricant, contact an authorized service center. If lubricant is present, the chain may be dull or the bar damaged.

What to do if my Ryobi RCS4240NB Chainsaw engine starts but the chain is not rotating?

  If the Ryobi Chainsaw engine starts but the chain doesn't rotate, it could be because the chain brake is engaged. Disengage the chain brake. Another reason might be that the chain tension is too tight, so adjust it according to the manual. Also, check if the guide bar and chain are assembled incorrectly. Inspect the guide bar and chain for any damage. If the drive sprocket teeth are damaged, contact an authorized service center for replacement.
