Possible Solution
1. Reduce feed rate.
2. Replace blade (Page 36).
1. Use file or stone to smooth and round the back of the

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 and guide bearings (Pages
24 and 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 50.
2. Clean all sawdust from rubber tires on wheels.
1. Adjust table tilt to 0˚; readjust positive stop if
necessary (Page 27).
2. Calibrate table tilt scale pointer to 0˚ (Page 27).
3. Shim table (Page 46).
Possible Solution
1. Reset the blade tensioner (Page 51).
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 45).
1. Adjust wheels to be coplanar/aligned with each other
(Page 47).
2. Redress the rubber tires on the wheels (Page 42);
replace the rubber tires on the wheels.
