How to troubleshoot starting issues with my Hatz Diesel 1B30 Engine?
- J
  Jeremy MurrayAug 14, 2025
  If your Hatz Diesel Engine won't start or hesitates but turns easily, make sure the speed control lever is in the "START" position. Also, check if there is fuel at the injection pump by adding fuel and systematically checking the entire fuel supply. Insufficient compression may be the issue, so check and adjust the tappet clearance if needed. If the temperature is below the start limit, activate the pre glow unit (if equipped). For cylinder/piston ring wear or a non-functional injection nozzle, contact the HATZ service station.

  If your Hatz Diesel Engine hesitates or doesn't start but turns easily, here are a few things to check: * **Speed control lever position:** Ensure the speed control lever is in the "START" operating position and the stop pin is not in the STOP position. * **Fuel supply:** Add fuel and systematically check the entire fuel supply system to ensure fuel is reaching the injection pump. * **Tappet clearance:** Check the tappet clearance and adjust if necessary. For cylinder/piston ring wear or a non-functional injection nozzle, contact the HATZ service station.

Why does my Hatz Diesel Engine lose power and emit black smoke?
- J
  Joseph McclainAug 21, 2025
  If your Hatz Diesel Engine loses power, speed, and emits black smoke, the air filter may be dirty. Try cleaning or replacing the air filter. Also, the tappet clearance might not be correct, so you should adjust it. If these steps don't resolve the issue, the injection nozzle might be malfunctioning, and you should contact the HATZ service station.

What to do if my Hatz Diesel 1B30 shuts off during operation?
- M
  Mary HuberAug 25, 2025
  If your Hatz Diesel Engine switches off spontaneously, it could be due to an interrupted fuel supply. Add fuel to the tank. Other potential causes include a clogged fuel filter (change it), a clogged tank vent (ensure sufficient venting), or air in the fuel system (check for air ingress and inspect the bleed valve). For mechanical faults, contact the HATZ service station.
