Why does my Husky Impact Driver run slowly or not operate?
- J
  Joshua BallJul 28, 2025
  Your Husky Impact Driver might be running slowly or not operating due to several reasons. It could be due to grit or gum in the tool, which can be resolved by flushing the tool with air tool oil or gum solvent. Another cause could be that the tool is out of oil; in this case, lubricate it according to the manual's lubrication instructions. Low air pressure or leaking air hoses can also be culprits; adjust the regulator to the maximum setting, check for leaks and tighten hose fittings, sealing them with pipe thread tape if necessary. Also, ensure the hose is the proper size, and directly connect the hoses together. Finally, worn components like a rotor blade or ball bearing in the motor may be the cause, requiring replacement or cleaning.

  If your Husky Impact Driver impacts slowly or not at all, it could be due to lack of lubrication. Lubricate the air motor and the impact mechanism according to the lubrication instructions in this manual. Another possible reason is that the tool regulator setting is in the wrong position; adjust the regulator on the tool to the maximum setting.

Why is there moisture blowing out of my Husky Impact Driver's exhaust?

  Stephen BensonAug 16, 2025
  If you notice moisture blowing out of your Husky Impact Driver's exhaust, it's likely due to water in the tank. Drain the tank, then lubricate the tool and run it until water is no longer evident. After that, lubricate the tool again and run it for 1-2 seconds.
