Why is my RF 812N Saw motor running too hot?
- K
  Kenneth SchwartzAug 13, 2025
  The motor of your RF Saw might be running too hot due to several reasons. It could be that the blade tension or the drive belt tension is too high, so you should reduce the tension on them. Alternatively, the blade might be too coarse or too fine for the material you are cutting, so try using a finer or coarser blade accordingly. Improperly aligned gears, gears needing lubrication, or the cut binding the blade could also be the cause. Adjust the gears so that the worm is in the center of the gear, check the oil path, or decrease feed and speed.

How to prevent excessive blade breakage on my RF 812N?

  To prevent excessive blade breakage on your RF Saw, make sure to clamp the work securely. Adjust the speed or feed if they are incorrect. If the blade teeth spacing is too large, replace it with a smaller teeth spacing blade. If the material is too coarse, use a blade of slow speed and small teeth spacing. Ensure the blade tension is properly adjusted so it doesn't slip on the wheel. Place the blade in contact with the work after the motor is started. Adjust the wheel alignment if the blade rubs on the wheel flange, and adjust the guide bearings if they are misaligned. If the blade is too thick, use a thinner one. If cracking occurs at the weld, weld again, paying attention to the weld skill.

What to do if my RF 812N is making bad (crooked) cuts?
- W
  William JacksonAug 20, 2025
  If your RF Saw is making bad, crooked cuts, several factors could be the cause. Begin by reducing the feed pressure by increasing the spring tension on the side of the saw. Ensure the guide bearings are properly adjusted with a clearance no greater than 0.001. Increase blade tension by adjusting the blade tension. Replace the blade if it's dull. Adjust the speed if it's incorrect and adjust the guide space if the blade guides are spaced out too much. Tighten the blade guide assembly if it is loose. Finally, re-track the blade according to the operating instructions if the blade truck is too far away from the wheel flanges.

How to fix premature blade dulling on my RF 812N?
- J
  Jeremy MartinezAug 25, 2025
  To address premature blade dulling on your RF Saw, consider these points. If the teeth are too coarse, switch to finer teeth. If the speed is too high, decrease it. If the feed pressure is inadequate, decrease the spring tension on the side of the saw. For hard spots or scale on the material, reduce speed and increase feed pressure. If there is work hardening of material, increase feed pressure by reducing.

What causes teeth ripping from the blade on my RF 812N?
- J
  jenniferfryeAug 28, 2025
  Teeth ripping from the blade on your RF Saw can occur due to several reasons. If the tooth is too coarse for the work, use a finer tooth blade. If the pressure is too heavy and the speed too slow, decrease the pressure and increase the speed. If the work-piece is vibrating, clamp it securely. If the gullets are loading, use a coarser tooth blade or a brush to remove chips.

What to do if my RF 812N is making bad (rough) cuts?
- J
  James CrawfordAug 31, 2025
  If your RF Saw is making bad, rough cuts, this could be due to too much speed or feed, so decrease them. Alternatively, the blade may be too coarse, so replace it with a finer blade. Also, check the blade tension and adjust it if it is loose.

Why is the blade twisting on my RF 812N?
- M
  Michael CookSep 4, 2025
  If the blade is twisting on your RF Saw, it could be that the cut is binding the blade, so decrease the feed pressure. It could also be due to too much blade tension, so decrease the blade tension.

What causes unusual wear on the side or back of the blade on my RF 812N?
- J
  Jessica RobinsonSep 8, 2025
  Unusual wear on the side or back of your RF Saw blade can be caused by worn blade guides, so replace them. It may also be caused by blade guide bearings not adjusted properly, so adjust them as per operators manual. If the blade guide bearing bracket is loose, tighten it.
