I have a DJ-20 8″ jointer.  After handling by the movers, the beds are out of alighnment .  After a little research I learned that the cross bars ar mounted in eccentric bushings held in place by set screws.  Any special precautions before I try to re-align?  Any ideas on what type of tool to engage the slots on the eccentric bushings? I plan to verify the outfeed table is level across the axis of the cutter bar, then paralle the infeed table to the outfeed.
