Grime-stoppers, rid your tablesaw of dust
It's ironic: Tablesaws create dust with every cut, but that same debris can restrict the saw's ability to tilt, elevate, and make more cuts. Even with effective dust collection in place, gunk tends to build up on the gears, trunnions, bearings, and motor. Here's how you can beat the dust gremlins.
Make a clean sweep
Begin your cleanup by sucking out as much debris as possible from inside the saw cabinet with a shop vacuum, preferably with a narrow nozzle. Be sure to wear eye and breathing protection. Next, close the access door and remove the blade from the arbor. With your dust collector running, blow compressed air into the throat opening to clear as much dust as possible, directing it toward the dust port.
After you've blown off all the dust you can through the blade throat, open or remove all the access doors and panels. Now blow out as much dust as possible by shooting compressed air through all the openings. You'll likely have to do this several times from above and below to completely evacuate the dust.
Next, use a steel or brass wire brush, right, to dislodge grime from your saw's gears, threaded rods, trunnions, and bevel stops. For tough grease-and-gunk deposits, dip the brush in mineral spirits and scrub. Just keep any such solvents well away from bearings to avoid damaging them.
