Why Bosch CM8S motor does not start?
- D
  Dominic JonesAug 18, 2025
  The Bosch Saw motor might not start due to several reasons. First, ensure the unit is properly plugged into a functioning outlet, or try a different outlet. It's also possible that the power source fuse or time delay fuse has blown, requiring a 15-Amp time delay fuse or circuit breaker replacement. Another potential cause is worn brushes, which may need replacement as described in the Maintenance and Lubrication section. If none of these solutions work, it may require authorized service.

  If the Bosch Saw blade binds, jams, burns wood, or makes rough cuts, consider the following: Ensure you are operating the saw correctly, as detailed in the Saw Operations section. A dull blade can cause these issues, so replace or sharpen it. Using the wrong blade can also lead to problems; replace it with an 8-1/2” diameter blade designed for the material you're cutting. Finally, a bent blade will cause these issues, so replace the blade.

What to do if Bosch Saw cannot rotate table to change miter angle?
- E
  Eric RussellAug 26, 2025
  If you cannot rotate the table to change the miter angle on your Bosch Saw, there are a few possible reasons. First, the miter lock knob may be tightened; turn it counterclockwise to loosen it. Second, the miter detent lever may be engaged with a detent (slot) in the detent plate; pull up on the miter detent lever to disengage it from the detent slot. Finally, sawdust accumulation can obstruct movement; vacuum or blow out dust around the turntable, wearing eye protection.

What to do if Bosch CM8S blade does not cut completely through workpiece?
- M
  Miguel JamesSep 2, 2025
  If the Bosch Saw blade does not cut completely through the workpiece, it could be because the depth stop plate is pulled out for non-through cuts. Push the depth stop plate inward to set it for full-depth cuts. Another reason could be that the replacement blade is less than 8-1/2” diameter; change to a blade that is fully 8-1/2” diameter.

  If the Bosch Saw head assembly will not fully raise or the blade guard will not fully close, several factors could be the cause. First, check if the head assembly lock pin is engaged and pull it out to allow the head assembly to go up. Sawdust accumulation can also obstruct movement; clean the head assembly. If neither of these solutions works, authorized service may be required.
