What to do if Hatz 2M41Z Engine does not start?
- C
  cheryl43Aug 16, 2025
  If your Hatz Engine doesn't start, consider these possible causes and solutions: * Ensure the speed control lever is correctly positioned. Depending on the situation, set it to the 1/2 start or max START position and ensure it remains fixed. * If there's no fuel at the injection pump, refuel. Also, try activating the manual lever of the fuel pump. * Systematically check the entire fuel supply system, including the fuel feed line to the engine, the fuel prefilter, and the main fuel filter. * Verify the function of the feed pump. If difficulties persist after extended periods of disuse, and activating the feed pump helps, verify the fuel system's sizing. If the injection nozzle isn't working, contact Hatz service.

  If your Hatz Engine doesn't start, make sure there is fuel at the injection pump by refueling. Also, activate the feed pump until you hear the fuel flowing back through the return line into the fuel tank. Depending on the possibility or requirement, place the lever in either the 1/2 start or max. START position and ensure the lever is fixed in this position. Systematically check the entire fuel supply: Check the feed line to the engine, the fuel prefilter, the fuel filter, and the function of the feed pump.

Why is my Hatz Engine losing power and speed?
- G
  George AllenAug 22, 2025
  If your Hatz Engine is losing power and speed, here are a few potential reasons: * If the speed adjustment lever won't stay put, try blocking it in the desired position. * Check the fuel supply. Make sure you haven't run out of fuel. Add fuel if needed. * A clogged fuel prefilter or main fuel filter can also cause this issue, so replace the fuel filter. * Also, ensure the tank is adequately vented and check the line screw connections for any leaks.

  Randy StaffordAug 26, 2025
  If your Hatz Engine is having trouble starting in cold weather, consider these factors: * Check the fuel. Ensure the fuel from the feed line is clear, not cloudy. If gelled, thaw the engine or drain the system and refill with temperature-resistant fuel. * If the oil is too viscous, change the engine oil and oil filter, using a suitable viscosity class. * Uncouple the engine from the machine, if possible.

  If your Hatz Engine starts but doesn't keep running after you release the starter, consider these possibilities: * Ensure the speed control lever is fully in the Start position. Set the lever to the Start position. * If possible, separate the engine from the machine by uncoupling it. * A clogged fuel prefilter or main fuel filter could be the culprit, so change the fuel prefilter or change the main fuel filter. * Systematically check the entire fuel supply to ensure it is not interrupted. * Check the oil level if there's a stop signal from monitoring elements due to low oil pressure.
