    What to do if my Central Pneumatic 65173 has decreased output?

      Lisa RasmussenJul 31, 2025
      If your Central Pneumatic Sander experiences decreased output, there are several potential causes to investigate. First, check for loose connections and ensure your air supply provides sufficient airflow (CFM) at the required pressure (PSI), not exceeding 90 PSI. Next, make sure that the trigger moves freely. Insufficient lubrication can also be the issue; lubricate the tool with air tool oil and grease as directed. Clean the air inlet screen to remove any buildup. Ensure the housing is properly assembled and tight. If these steps don't resolve the issue, a qualified technician should clean and lubricate the internal mechanism, and you may need to install an in-line filter in your air supply. Also, consider removing, washing, or replacing the filter.

      Michele WilsonAug 10, 2025
      If the housing of your Central Pneumatic Sander heats up during use, it could be due to incorrect or insufficient lubrication. Make sure to lubricate the tool with air tool oil and grease according to the directions. Another potential cause is worn parts, in which case a qualified technician should inspect the internal mechanism and replace parts as needed.

    What to do if my Central Pneumatic 65173 has severe air leakage?

      William WoodAug 20, 2025
      If your Central Pneumatic Sander has severe air leakage (note that slight leakage is normal, especially in older tools), it could be due to several reasons. Check for cross-threaded housing components, looking for incorrect alignment and uneven gaps. If cross-threading is present, disassemble and replace the damaged parts before using the tool. Also, ensure the housing is tightened properly. If the housing cannot be tightened properly, the internal parts may be misaligned. Damaged valves or housing components can also cause air leakage, and these components should be replaced if damaged.
