Chain

[Glenn]

The chain came off after turning the wheel to adjust the depth of the planer. It was turning really hard prior to it coming off.

I was having the same problem when I noticed one of the threaded posts that the sprockets are on was turning with the sprocket. It totally wacked that one corner. I adjusted the post(it has flats spots on the bottom enabling the use of an adjustable wrench), then tightened the screw underneath. Raises and lowers much better. B&D should have designed it with teeth on the bottom of those posts so they won't turn after being tightened. I still have to replace both bearings in the motor (totally trashed), replace fan shroud, and a few other things...then should be like new.
