440V Conversion
The Model G0772 can be converted for 440V
operation using the optional Part# P07721412.
This can be purchased by contacting the Grizzly
Order Desk at (800) 523-4777. This conversion
job consists of: 1) replacing the overload relays, 2)
rewiring the transformer for 440V operation, and
3) rewiring the main and scoring blade motors for
440V operation.
All wiring changes must be done by an electrician
or qualified service personnel before the saw is
connected to the power source. If, at any time
during this procedure you need help, call Grizzly
Tech Support at (570) 546-9663.
Before performing the conversion procedure, we
recommend setting the blade to 0° and raising it
all the way up to create clearance under the main
and scoring motor junction boxes for rewiring.
To convert G0772 for 440V operation:
3. Remove main motor overload relay for 220V.
Replace with RHU-10/7.5K1 overload relay
included with 440V Conversion Kit. Set over-
load dial to 6.5A (see
Figure 9).
4. Remove scoring motor overload relay for
220V. Replace with RHU-10/2K1 overload
relay included with 440V Conversion Kit. Set
amperage dial to 1.6A (see
Figure 9).
