Possible Solution
1. Reduce feed rate.
2. Replace blade (Page 36).
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 36).
1. Re-install insert a different way.
2. Align table (Page 29).
1. Tighten or replace blade (Page 36).
2. Clean all sawdust from rubber tires on wheels.
1. Feed workpiece straight into the blade.
2. Install a smaller width blade/increase blade
tension (Page 34).
1. Reduce feed rate.
2. Re-adjust all blade support bearings and blade
guide blocks (Pages 27 and Page 26).
1. Clean out dust port.
2. Three options:
—Check dust lines for leaks or clogs.
—Move dust collector closer to saw.
—Install a more powerful dust collector.
1. Refer to Blade Lead on Page 52.
2. Clean all sawdust from rubber tires on wheels.
1. Adjust table tilt to 0˚; readjust positive stop if
necessary (Page 22).
2. Calibrate table tilt scale pointer to 0˚ (Page 28).
3. Shim table (Page 48).
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 47).
1. Adjust wheels to be coplanar/aligned with each
other (Page 49).
2. Redress the rubber tires on the wheels (Page
44); replace the rubber tires on the wheels.
