Possible Solution
1. Reduce feed rate.
2. Replace blade (Page 34).
1. Use file or stone to smooth and round the back of the
blade; slightly loosen the blade guides.
2. Inspect and replace blade if necessary (Page 34).
1. Re-install insert a different way.

1. Tighten or replace blade (Page 34).
2. Clean all sawdust from rubber tires on wheels.
1. Feed workpiece straight into the blade. See Basic
Cutting Tips on Page 26.
2. Install a smaller width blade/increase blade tension.
See Page 34 or 20.
1. Reduce feed rate.
2. Re-adjust all blade guides and support bearings.
1. Clean out dust port.
2. Three options:
—Check dust hoses for leaks or clogs.
—Connect saw to a more powerful shop vacuum.
1. Refer to Blade Lead on Page 42.
2. Clean all sawdust from rubber tires on wheels.
1. Adjust table tilt to 0˚; readjust positive stop if neces-
sary (Page 23).
2. Calibrate table tilt scale pointer to 0˚ (Page 23).
3. Shim table (Page 42).
Possible Solution
1. Replace spring in the blade tension mechanism,
then take better care of the bandsaw by releasing
tension when not in use and not over-tensioning the
blade.
1. Replace the wheel bearing.
2. Check/loosen the belt tension (Page 40).
1. Adjust wheels to be coplanar/aligned with each other
(Page 43).
2. Redress the rubber tires on the wheels (Page 37);
