ProbleM Possible Cause solutioN
1) Excessive
vibration. 1. blade out of balance.
2. blade is damaged.
3. saw is not mounted securely.
4. Work surface is uneven.
5. blade is warped. 1. Replace blade.
2. Replace blade.
3. Tighten all hardware.
4. Reposition on flat surface. adjust legs.
5. Check saw blade installation. Replace
blade if necessary.
2) Rip fence does not
move smoothly. 1. Rip fence not mounted correctly.
2. Rails are dirty or sticky.

3) Cutting stalls
motor, burns work.
binds, stops when
ripping. 1. dull blade.
