wheel° Do not attempt to sharpen while on the mower°

bafancer, follow the instructions supplied with bal-
anGer),,
° Slide blade on to an unthreaded portion of the steel bolt
or pin and hold the bolt or pin parallel with the ground.
If blade is balanced, it should remain in a horizontal
position.. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced

the center hole may appear to be centered, but are not..
