What to do if Central Pneumatic 91773 Sander has severe air leakage?
- B
  Bruce BaileyJul 31, 2025
  If your Central Pneumatic Sander has severe air leakage, inspect the housing components for cross-threading, incorrect alignment, and uneven gaps; if found, disassemble and replace damaged parts. Ensure the housing is tightened properly; misalignment of internal parts may be the reason if it won't tighten. Also, check for a damaged valve or housing and replace any damaged components. Finally, inspect the valve assembly for dirt, wear, or damage; clean or replace it as necessary.

  If your Central Pneumatic Sander has severe air leakage (note that slight air leakage is normal, especially on older tools), check for incorrect alignment and uneven gaps in the housing components, which could indicate cross-threading. If cross-threaded, disassemble and replace the damaged parts before use. Also, try tightening the housing assembly. If it still leaks, the internal parts may be misaligned. If tightening doesn't solve the issue, you may need to replace damaged components or clean/replace the valve assembly.

How to fix decreased output on my Central Pneumatic 91773 Sander?
- D
  danielsandersAug 10, 2025
  If you're experiencing decreased output from your Central Pneumatic Sander, start by checking for loose connections and ensuring that the air supply provides enough air flow (CFM) at the required pressure (PSI), without exceeding the maximum air pressure. Then, clean around the trigger to ensure free movement and lubricate the tool using air tool oil and grease according to the directions. Also, clean the air inlet screen of any buildup, and make sure the housing is properly assembled and tight. If these steps don't resolve the issue, have a qualified technician clean and lubricate the mechanism, and consider installing an in-line filter in the air supply.

Why Central Pneumatic 91773 has decreased output?

  johnsonlawrenceAug 19, 2025
  Several factors can cause decreased output in your Central Pneumatic Sander. It could be due to insufficient air pressure or airflow—check for loose connections and ensure your air supply meets the tool's CFM and PSI requirements, without exceeding the maximum air pressure. An obstructed trigger, incorrect or insufficient lubrication, a blocked air inlet screen, a loose housing, or a contaminated mechanism could also be the cause. Clean the trigger, lubricate the tool with air tool oil, clean the air inlet screen, tighten the housing, or have a technician clean and lubricate the mechanism, respectively. Consider installing an in-line filter.

Why Central Pneumatic Sander housing heats during use?
- L
  Lindsey SteeleAug 26, 2025
  If the housing of your Central Pneumatic Sander heats up during use, it may be due to incorrect or insufficient lubrication. Make sure to lubricate it properly with air tool oil according to the directions. Alternatively, worn parts inside the tool could be the cause. In this case, have a qualified technician inspect the internal mechanism and replace any worn parts as needed.
