G0456 Variable Speed Wood Lathe
The Model G0456 features a DC motor, which
uses heavy-duty carbon brushes. While these
brushes are designed for extended life, they will
eventually wear out, causing a loss of power or
faulty starting. This procedure takes approxi-
mately 45 minutes to complete and requires you
to remove and discard the sandpaper disc if it is
installed. If you need help locating any parts of
the machine, refer to the parts breakdown.
