FM-04: Blade Speed Or Cutting Force Is Below Normal
The blade turns, but speed or cutting force is below normal in a correctly supported wood cut.
Diagnostic overview
The blade turns, but speed or cutting force is below normal in a correctly supported wood cut.
Likely Root Causes
- Battery charge or output is too low for the load
- Blade is dull, dirty, damaged, or unsuitable
- Blade rotation, size, arbor, or speed rating is incorrect
- Cut depth is excessive or feed pressure is too high
- Motor, bearing, or electronic drive fault
Quick Checks
- A clean supported test cut proceeds smoothly at normal blade speed.
Repair Preview
- Release the trigger, remove the battery, and inspect the installed blade.
- Fit a clean sharp blade of the correct size, arbor, rotation, tooth count, and speed rating.
- Set depth so about one-half tooth projects below the work and support the material near the cut.
- - Test with a charged known-good pack and steady feed - if output stays low, seek service.
