Why won't the starter turn on my Jungheinrich DFG 320 Forklifts?
- A
  Anthony WheelerAug 23, 2025
  If the starter of your Jungheinrich Forklifts does not turn, it could be due to several reasons. First, make sure the travel direction switch is in neutral. If not, turn it to the neutral position. A low battery charge could also be the culprit; check the battery charge and charge it if needed. Additionally, inspect the battery terminals for looseness or oxidation; clean and grease them, and tighten the battery terminal cable. Check the starter cable for any damage and ensure it's properly tightened or replaced if necessary. Finally, see if the starter magnetic switch is jammed, and check if it audibly engages.

  If the engine temperature display on your Jungheinrich Forklifts is in the red zone, it could be due to several reasons. Check the engine oil level and top it up if necessary. Also, the radiator might be contaminated, so clean it. Ensure the coolant level is adequate, checking the engine radiator system for leaks and adding coolant if needed. Lastly, a slipping fan V-belt can cause overheating, so check the V-belt tension, tightening or replacing it as required.
