Some things to check are. 1) are the belts old and stiff? 2) is everything lubed correctly? 3) Condition of the sheaves in the lower ranges. 4) If it is a vari-speed, was it run at one speed for a long long time creating some wear grooves in the sheaves? 5) Is there vibration with some or all cutting set-up? such as boring head, drill chuck, flycutter.
Check thes out and let us know what you have discovered.
