inaccurate.
1. The spring in the blade tension mechanism
has lost its "spring." This is caused by not
releasing the blade tension when not in use or
frequently over-tensioning the bandsaw.
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.
Wheel is noisy. 1. Wheel bearing is worn out.
2. Belt is too tight (lower wheel).
1. Replace the wheel bearing.
2. Check/loosen the belt tension as described in the
Blade Speed instructions on
Page 31.
Blade does
not track
consistently,
correctly, or at
all.
1. Wheels are not coplanar or aligned with each
other.
2. Rubber tires on wheels are worn out.
1. Adjust wheels to be coplanar/aligned with each other
