    Why does my Jet Saw blade keep breaking?
    • E
      efriedmanAug 15, 2025
      Excessive blade breakage in your Jet Saw can occur for several reasons. It may be caused by loose material in the vise (clamp work securely), incorrect speed or feed (check machinist’s handbook for appropriate settings), teeth that are too coarse for the material (check machinist’s handbook for blade type), incorrect blade tension (adjust until the blade doesn't slip), the blade contacting the workpiece before starting (start motor first), the blade rubbing on the wheel flange (adjust blade tracking), misaligned guides (adjust guides), or cracking at the weld (longer annealing cycle).

    How to fix out-of-square cuts with my Jet J-7020?
    • D
      Daniel StaffordAug 19, 2025
      Out-of-square cuts with your Jet Saw can arise from several factors. Ensure the workpiece is square with the blade by adjusting the vise and clamping the work tightly. Other causes include excessive feed pressure (decrease pressure), improperly adjusted guide bearings (adjust clearance to 0.001-0.002 inch), inadequate blade tension (gradually increase tension), excessive span between blade guides (move guide bar closer to work), a dull blade (replace blade), incorrect blade speed (check blade speed), a loose blade guide assembly (tighten assembly), a loose blade guide bearing assembly (tighten bearing assembly), blade tracking too far from wheel flanges (adjust tracking), or a worn guide bearing (replace bearing).

    Why is my Jet J-7020 blade dulling so quickly?
    • M
      Mandy StricklandAug 21, 2025
      Premature blade dulling in your Jet Saw could be due to several reasons. The blade teeth might be too coarse (use a finer tooth blade), the blade speed might be too high (try a lower speed), or the feed pressure may be inadequate (decrease spring tension). Other potential causes include hard spots or scale on the workpiece (increase feed pressure for hard spots, reduce speed and increase feed pressure for scale), work hardening of the material (increase feed pressure by reducing spring tension), insufficient blade tension (increase tension), or operating the saw without pressure on the workpiece (do not run blade at idle).

    What to do if my Jet J-7020 motor is running too hot?
    • J
      Justin NewmanAug 26, 2025
      If your Jet Saw motor is overheating, several factors could be responsible. These include excessive blade tension (reduce tension), excessive drive belt tension (reduce tension), using a blade too coarse for the workpiece (use a blade with fine tooth pitch), using a blade too fine for the workpiece (use a blade with coarse tooth pitch), or the speed reducer gears requiring lubrication (check speed reducer).

    Why are teeth missing or ripped from my Jet J-7020 blade?
    • S
      stanleyprinceAug 27, 2025
      Missing or ripped teeth on your Jet Saw blade can be caused by several issues: using a blade tooth pitch that's too coarse for the workpiece (use a blade with finer tooth pitch), incorrect feed pressure (increase feed pressure and/or blade speed if too slow), workpiece vibration (clamp securely), or gullets loading up with chips (use a blade with a coarse tooth pitch and reduce feed pressure). Also, ensure you brush the blade to remove chips.

    What causes rough cuts on my Jet Saw?
    • S
      Stephanie DanielAug 30, 2025
      Rough cuts on your Jet Saw can occur if the blade speed is too high for the feed pressure (reduce both), or if the blade is too coarse (replace with a finer blade).

    Why is there no coolant flow in my Jet J-7020?
    • A
      Angela MahoneySep 3, 2025
      Lack of coolant flow in your Jet Saw may be due to a burned-out pump motor (replace pump), a clogged screen/filter on the pump (clean it), a loose impeller (tighten it), or a coolant level that is too low (add coolant to the reservoir).

    Why is there unusual wear on the side or back of my Jet Saw blade?
    • A
      Ann FloresSep 5, 2025
      Unusual wear on the side or back of your Jet Saw blade can be attributed to worn blade guides (replace them), improperly adjusted blade guide bearings (adjust them), or a loose blade guide bearing bracket (tighten it).

    Why is the blade twisting on my Jet J-7020 Saw?
    • C
      Carlos OlsonSep 8, 2025
      Blade twisting on your Jet Saw can be caused by the blade binding in the cut (decrease feed pressure) or the blade tension being too high (decrease tension).

    What causes excessive noise or vibration from the speed reducer in my Jet J-7020?
    • E
      erica42Sep 12, 2025
      Excessive noise or vibration from the speed reducer in your Jet Saw can occur if the V-belt is too tight (reset V-belt tension) or if the countering spring is not tensioned properly (increase spring tension).
