Rewiring to 110V
The Model G0643 can be converted for 110V
operation. This conversion job consists of dis-
connecting the machine from the power source,
replacing the electrical box, replacing the ON but-
ton/lamp, and rewiring the motor for 110V opera-
tion.
The necessary electrical box and ON button/
lamp for this procedure is the Model G0643 110V
Conversion Kit (Part No. P0643222), and can be
purchased by calling Grizzly Customer Service at
(800) 523-4777.
All wiring changes must be inspected by a quali-
fied electrician before the boring machine 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.
