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
Page 42.
the necessary magnetic switch for this procedure
can be purchased by calling grizzly Customer
service at (800) 523-4777 and ordering Model
g8296 (3-phase 440v 10hp Mag switch).
all wiring changes must be inspected by a quali-
fied electrician before the dust collector is con-
nected to the power source. if, at any time during
this procedure you need help, call grizzly tech
support at (570) 546-9663.
