Why is my Wacker Neuson EHB 11 BLM Power Hammer not working?
- A
  Anne GarciaAug 12, 2025
  If your Wacker Neuson Power Hammer isn't working, it might be due to several reasons: * **Incorrect Voltage:** For 230V machines, ensure the input voltage is between 80V and 300V. For 115V machines, it should be between 45V and 150V. Use an extension cable with a sufficient cross-section if needed. * **Overheated Inverter:** If the inverter has shut off due to excessive temperature, allow the machine to cool down. * **Power Cable Issues:** Check the power cable for any interruptions and replace it if it's defective.

  If the drill on your Wacker Neuson Power Hammer gets stuck, it could be due to: * **Excessive Dust:** Too much borer dust in the borehole. To resolve this, pull the drill bit out of the borehole and remove the dust from the drill bit. * **Reinforcing Steel:** Interference from reinforcing steel. In this case, you should redrill the borehole.

How to fix blocked percussion system on Wacker Neuson EHB 11 BLM?
- A
  Amy MartinAug 20, 2025
  If the percussion system on your Wacker Neuson Power Hammer is blocked, it might be because: * **Low Temperatures:** High grease resistance due to very low temperatures. Allow the machine to warm up in a warm environment, such as a heated room. * **Seized Parts:** Moving parts seizing, possibly due to prolonged dry running. If this is the case, have the defective components replaced.

  Sean JonesAug 25, 2025
  If your Wacker Neuson Power Hammer isn't working, there are several potential causes. First, the input voltage might be too high (over 300 V or 150 V) or too low (below 80 V or 45 V). Ensure you are providing the correct voltage, and if needed, use an extension cable with an adequate cross-section. Another possibility is that the inverter has shut off because it's too hot; in this case, let the machine cool off. Finally, the power cable could be interrupted. Check the cable and replace it if it's defective.

  A blocked percussion system in your Wacker Neuson Power Hammer can be caused by high grease resistance due to very low temperatures. To resolve this, allow the machine to warm up in a warm environment, such as a heated room. Alternatively, the moving parts may be seizing, possibly due to prolonged dry running. If this is the case, have the defective components replaced.

  If your Wacker Neuson Tools machine isn't working, there could be several reasons: * **Incorrect Voltage:** For 230V machines, ensure the input voltage is between 80V and 300V. For 115V machines, it should be between 45V and 150V. Use an extension cable with sufficient cross-section if needed to correct the voltage. * **Overheating:** If the inverter has shut off due to excessive temperature, allow the machine to cool down. * **Power Cable Issues:** Check the power cable for any interruptions or damage. If defective, have it replaced.

  Your Wacker Neuson Tools drill might be jammed due to: * **Excessive Borer Dust:** Too much dust in the borehole can cause the drill to get stuck. Pull the drill bit out and remove the dust. * **Reinforcing Steel:** If the drill encounters interfering reinforcing steel, you'll need to redrill the borehole.
