How to fix an Efco Chainsaw that won't start or dies after a few seconds?

  If your Efco chainsaw won't start or dies shortly after starting, ensure the switch is in the 'I' position. The issue might be due to: * No spark. Check the spark plug for a spark. If there's no spark, try again with a new spark plug (CMR7A). * The engine is flooded. Follow the procedure on page 20. If the engine still won't start, repeat the procedure with a new spark plug.

Why are the bar and chain on my Efco Chainsaw getting hot and smoking?
- M

  The bar and chain may be getting hot and smoking because the chain oil tank is empty, the chain tension is too tight, or there is a malfunction in the lubrication system. To resolve this: * Refill the chain oil tank whenever you refill the fuel tank. * Check the chain tension. * Run the chainsaw at full throttle for 15-30 seconds, then stop and check if oil is dripping from the bar tip. If there is no oil, contact an Authorized Service Center.

Use fresh gasoline and the appropriate 2-stroke engine oil. * The air filter might be dirty. Clean the air filter. * The carburetor might need adjustment. Contact an Authorized Service Center to adjust the carburetor.
