I have not had any problem with the belt on my '470 slipping, but then we
don't have cold WX in Arizona <grin>.
It could be the clutch on the driven pulley that is slipping, and that is
adjustable. Just keep in mind that the clutch is a safety device, designed
to slip when the tower is fully extended against the stops. Slipping
clutches save broken cables (and destroyed towers).
