the Model
g0673 can be converted for 440V
operation. this conversion job consists of discon-
necting the dust collector from the power source,
changing the magnetic switch, and rewiring the
motor for 440V operation, as shown on
necting the dust collector from the power source,
changing the magnetic switch, and rewiring the
motor for 440V operation, as shown on
page 42.
