I am having difficulty getting the bandsaw blade to track correctly. The blade will only track very close to front edge (closest to operator) of top wheel and often comes off of the wheel. The adjusting screw tilts the wheel but it does not correct the problem. Nothing is obviously broken but after removing the top wheel I have noticed that back outer edge of the wheel hub has been rubbing. I would appreciate suggestions for correcting problem. Thanks
It sounds like the charger has gone bad. This style of charger doesn't have any of the circuitry to protect it from a shorted out battery that many of today's more advanced chargers have. Because of this if you plug a shorted battery into the charger the bad battery will destroy the charger. You will need to have your batteries tested before you replace the charger to ensure that a bad battery doesn't also ruin your new charger. A local repair shop should be able to test your batteries for you.
The new charger is part #2607225367 and is available from http://www.ereplacementparts.com.
