    What to do if my RIDGID Saw motor does not start?
    • S
      Sandra KimSep 12, 2025
      If the RIDGID Saw motor isn't starting, first check the fuse or circuit breaker. If that's not the issue, the brushes may be worn and should be inspected according to the “Maintenance” section. For any other issues, get authorized service.

    Why does the brake on my RIDGID MS1290LZ not stop the blade within 6 seconds?
    • M
      Matthew DonovanAug 21, 2025
      If the RIDGID Saw's brake doesn't stop the blade within 6 seconds, it could be due to several reasons. First, inspect, clean, or replace the brushes as described in the “Maintenance” section if they are not seated or are sticking. Second, ensure you are using recommended blades/accessories and allow the motor to cool down if it has overheated from using prohibited accessories or rapid on/off cycling. Third, retighten the arbor screw if it is loose. For any other issues with the brake, get authorized service and refer to the “Troubleshooting of brake” section.

    Why does the RIDGID MS1290LZ blade bind and burn wood?
    • T
      Tasha MuellerAug 26, 2025
      The RIDGID Saw blade might bind, jam, burn wood, or produce rough cuts due to several reasons: improper operation, a dull blade (in which case you should sharpen or replace it), using the wrong blade (replace it with a 12” diameter blade designed for the material you're cutting), or a bent blade (replace the blade).

    Why does my RIDGID MS1290LZ vibrate or shake?
    • S
      Susan MooreAug 27, 2025
      Your RIDGID Saw might vibrate or shake because the saw blade is not round or is damaged, in which case you should replace the blade. Another reason might be that the saw blade is loose, so you should tighten the arbor screw.

    What to do if the RIDGID MS1290LZ blade brake doesn't stop the blade within 6 seconds?
    • S
      Susan BookerAug 30, 2025
      If the brake on your RIDGID Saw doesn't stop the blade within 6 seconds, it could be due to brushes not seated or lightly sticking (inspect, clean, or replace them), the motor brake winding overheated from use of prohibited accessory or rapid on/off cycling (use only recommended blades/accessories and let the motor cool down), or a loose arbor screw (retighten it).

    What to do if the RIDGID MS1290LZ power head won’t fully rise or the blade guard won’t fully close?
    • E
      Eileen ThomasSep 3, 2025
      If the power head on your RIDGID Saw doesn’t fully rise or the blade guard doesn’t fully close, it may be that lubrication is needed, there is part failure, the pivot spring or guard spring not replaced properly after service, or sawdust sticking to stops (inspect/clean stops).

    • P
      Paula DurhamSep 7, 2025
      If you can’t move the miter adjustment on your RIDGID Saw, it's likely due to sawdust under the table. Vacuum or blow out the dust, and be sure to wear eye protection while doing so.
