Can the top wheel exhibit any free play when the saw is tuned
correctly? I've got a Jet 18 inch, and the top wheel seems to be
adjusted - tracking is good, with blade running right in the center of
the tires - however the top wheel will wobble side to side. Up/down
free play seems to be negligible; I assume due to proper setting of
the tracking adjustment screw. The side to side freeplay lessens
somewhat when the blade is tensioned, but will still move.

I guess I thought it should be rigid, like a properly adjusted vehicle
wheel bearing. Bottom wheel is very solidly adjusted, doesn't move
either way.

Anything to worry about?

Thanks,
John Sellers
