Symptoms
- Saw stalls or jumps partway through a cut
- Blade smokes or slows under load
- Wood pinches the blade
- Saw kicks back toward you
Likely causes
- CommonWorkpiece not supported on both sides of the cut lineUnsupported wood sags and closes the kerf onto the blade.
- CommonNo riving knife/splitter, or it's misalignedWithout one, the kerf can close right behind the blade.
- PossibleBlade is dull or has pitch buildupA dull blade needs more force, increasing binding risk.
- PossibleCutting freehand without a guideWandering off line twists the blade in the cut.
- Less commonWarped or stressed lumber releasing tension when cutInternal stress can snap the kerf shut as you cut.
What to do
- Stop the saw and let the blade fully stop before backing it out of a pinched cut.
- Set up sawhorses or a cutting table so both sides of the cut are supported, not just one.
- Check that the riving knife or anti-kickback splitter is installed and aligned with the blade.
- Use a straightedge guide clamped to the work so the blade tracks straight instead of wandering.
- Inspect the blade for dullness or resin buildup; clean or replace it if cuts feel forced.
- Keep the saw's base plate flat on the work and let the blade do the cutting instead of pushing hard.
- Always stand to the side of the cutting line, never directly behind the blade, in case of kickback.

When to call a pro
If cuts are binding even with proper support and a sharp blade, a saw repair shop can check for a bent blade arbor or misaligned base plate.
Safety
Use caution
Kickback from a binding saw can throw the tool back at you; keep your body out of the blade's line of travel and use both hands.
