  If your EMAK Chainsaw engine isn't reaching full speed or is emitting excessive smoke, there are several potential causes: 1. **Incorrect fuel mixture:** Ensure you are using fresh fuel and the correct 2-cycle oil mix. 2. **Dirty air filter:** Clean the air filter according to the instructions in the Maintenance- Air Filter Section. 3. **Carburetor issues:** The carburetor may require adjustment; contact a Servicing Dealer for assistance.

  If your EMAK Chainsaw engine won't start or only runs briefly, it could be due to: 1. **No spark:** Check for a spark at the spark plug tip. If there's no spark, try again with a new spark plug (CMR7A). 2. **Flooded engine:** Follow the procedure on page 28. If it still fails, repeat the procedure with a new spark plug.

  If the bar and chain on your EMAK Chainsaw are running hot and smoking, consider these possibilities: 1. **Empty chain oil tank:** Refill the oil tank each time you fill the fuel tank. 2. **Overly tight chain tension:** Adjust the chain tension following the instructions in the Operation-Chain Tension section (Pag.25). 3. **Oiler malfunction:** Run the saw at full throttle for 15 to 30 seconds, then stop it and check for oil dripping from the bar tip guard and guide bar. If there is no oil, contact a Servicing Dealer.
