2. Clean and lubricate/wax rails.
3. Adjust clamp screw (Page 74).
1. Learn/use proper feeding technique.
2. Adjust fence parallel with blade (Page 75).
3. Use jointer to straighten edge of workpiece that
slides against fence.
1. Replace blade (Page 34).
2. Adjust miter slot parallel with blade (Page 69).
1. Adjust 45°/90° stop nuts (Page 67).

stop nuts; lubricate as necessary.
1. Clean sawdust or debris out of trunnion slides.
2. Adjust miter slot parallel with blade (Page 69).
3. Correctly install blade (Page 34).
4. Adjust table or trunnion mounting position
(Page 69).
5. Verify that blade arbor washers are correct and in
the required position.
1. Always cut bowed workpiece with cupped side
against table; use different board or use jointer to

2. Reduce feed rate and apply consistent pressure
through entire cut.
3. Replace blade (Page 34).
4. Change blade to one with fewer teeth.
