Why Hatz Engine won't start?
- P
  Patrick AndersonAug 19, 2025
  Your Hatz engine might not be starting due to several reasons. First, make sure the speed control lever is in the START position. Also, verify that the stop pin is not engaged in the STOP position; pull it lightly to the operating position. Check if there's fuel at the injection pump and refuel if necessary. Finally, insufficient compression due to wrong tappet clearance can also be a cause; in this case, check and adjust the tappet clearance.

  If your Hatz engine is losing power and speed, there are a few potential causes. First, ensure the speed adjustment lever stays in the desired position; if it doesn't, block it. Also, check the fuel level and add fuel if the tank is empty. Lastly, a clogged fuel filter can restrict fuel flow, so consider changing the fuel filter.

How to start Hatz Engine in cold weather?

  If your Hatz engine won't start in low temperatures, consider these possibilities. If the temperature is below the starting limit, activate the pre-glow system, if available. Fuel may have gelled due to insufficient cold resistance; check if the fuel is clear and not cloudy, and if gelled, thaw the engine or replace the fuel with a temperature-resistant mixture. Also, viscous oil can slow the starter, so change the engine oil to a suitable viscosity. Check the battery and contact the service center if necessary. If possible, separate the engine from the machine by uncoupling it.

  If your Hatz engine is overheating and the temperature indicator lamp is on, there are several potential causes. One possibility is too much engine oil; drain the oil to the upper mark on the dipstick. Another cause is inadequate cooling due to contamination in the cooling air guides; clean the cooling air area. Also, check the air guide parts and shafts for completeness and good sealing properties.

What to do if my Hatz Engine shuts off while running?
- W
  williamsconnieSep 1, 2025
  If your Hatz engine spontaneously shuts off, there are a few things to check. The most common reason is simply running out of fuel, so refill the tank. A clogged fuel filter can also cause this, so replace the fuel filter. Ensure that the tank is adequately vented, as a clogged tank vent can also cause the engine to stop. If none of these resolves the issue, it may be due to mechanical faults, and you should contact Hatz Service.

How to troubleshoot a Hatz 1B20 that won't start?
- M
  Matthew BradleySep 5, 2025
  If your Hatz Engine doesn't start or is hard to start but turns easily, first, ensure the speed control lever is in the START position. Next, check that the stop pin is not engaged; pull it lightly to the operating position. Also, make sure there is enough fuel. If these steps don't work, there may be insufficient compression due to wrong tappet clearance, which requires checking and adjustment. For cylinder or piston ring wear, contact Hatz Service.
