which may be lodged in them. Lodged chips can prevent
rotation of the guide rollers and cause flat spots on the
guide rollers.

rubber tires should be inspected for looseness or damage
when changing the blade. Wipe any chips from the rubber
tires on the pulleys with a brush.

tool with loose or damaged rubber tires will cause unstable
travel of the band saw blade.
