Identifying Original Sumec Firman Generators:

To avoid falling victim to fake products, here are key indicators to spot an original Sumec Firman generator:

  1. Look for the boldly engraved name “FIRMAN” on the fuel tank (for petrol generators).
  2. The name “FIRMAN” should also be engraved on the AVR, air filter, engine block, alternator rear frame, carburetor, cylinder head cover, and muffler.
  3. If the name “FIRMAN” is not engraved on these parts, be cautious and consider it a potential fake.
  4. Only the name “FIRMAN” should be engraved, not “SUMEC FIRMAN” or “SUMEC” on the mentioned parts.
  5. Note the unique way the “F” in “FIRMAN” is written, with a dot as its middle piece.
