  If your Lumag Grinder's motor won't start, several issues could be the cause. First, ensure you have enough fuel by filling the fuel tank. Next, check the engine oil level and refill if necessary. A dirty or faulty spark plug can also prevent starting, so clean or replace it. If the motor is cold, make sure the choke is set to the CLOSE (left) position. Finally, verify that the fuel tap is set to ON. If the starter is defective, repair it.

  If your Lumag Grinder engine gets too hot, it might be due to several reasons. First, check the engine oil level and refill if it's too low. Also, ensure that the cooling air system is clean by cleaning the fan grille and internal cooling fins. A polluted air filter can also cause overheating, so clean the air filter. If the carburetor is not set correctly, specialist dealers should be hired.
