Why does my Power Fist 8844136 Sander lose power?

  Brittany ReidAug 5, 2025
  Loss of power or erratic performance in your Power Fist Sander can occur due to several reasons. First, check for excessive drain on the air hose or incorrect hose connectors, ensuring the fitting is correct for the inlet bushing. Secondly, moisture or restrictions in the air hose/tank can be a cause; depressurize the system and drain any water. Also, verify that your air compressor has sufficient flow to match the tool's requirements. Finally, inspect the air hose for leaks and tighten and seal any leaking hose fittings with tape.

First, check the air inlet filter for blockage. You can also try pouring air tool lubricating oil into the air inlet as per the lubrication instructions to clear shipping grease, and operate the tool in short bursts to clear debris. If the tool remains jammed, clean and lubricate it according to the lubrication instructions. Another possible cause is that the air regulator is in a closed position; open the air regulator to the desired airflow. Finally, the issue could be damage or excessive wear of internal parts, in which case you should have a qualified technician service the tool or replace t...
