How to fix a Kobalt SGY-AIR220 Grinder that runs slowly?
- NNancy WestAug 3, 2025
To troubleshoot a Kobalt Grinder that runs slowly, consider these points: 1. Check for grit or gum inside the tool and flush it with air-tool oil or gum solvent. 2. Ensure the tool is properly lubricated. 3. Verify adequate air pressure by adjusting the tool's regulator to the maximum setting and the compressor regulator to a maximum of 90 PSI. 4. Inspect for air hose leaks and tighten/seal any found fittings. 5. Address potential pressure drops by using an appropriately sized hose and avoiding multiple hoses connected by quick-connect fittings. 6. Consider replacing a worn rotor blade. 7. If there's moisture in the exhaust, drain the air compressor tank and then oil the tool, running it until no more water is visible; repeat the oiling and running for 1-2 seconds.
