G1004/1008 Vertical Milling Machine
We have covered some basic electrical
requirements for the safe operation of your
Milling Machine. These requirements are
not necessarily comprehensive. You must
be sure that your particular electrical con-
figuration complies with local and state
codes. Ensure compliance by checking
with your local municipality or a licensed
electrician.
Potential for electrical shock hazard, this
equipment must be grounded. Verify that
any existing electrical outlet and circuit you
intend to plug into is actually grounded. Under
no circumstances should the grounding pin
from any three-pronged plug be removed.
Serious personal injury may occur.
220V Operation
The Model G1004/G1008 has a motor which can
be operated on a 220V single phase circuit. In
order to operate at 220V it is necessary to rewire
the motor connections (refer to the wiring dia-
grams at the back of this manual) and to add a
220V capable cord and plug. The style of plug
you require will depend upon the type of service
you currently have or plan to install. Figure 2
shows recommended plug styles.
The motor will safely draw about 8 amps at 220V
under load, therefore it should be connected to a
circuit that is protected by a 15 amp fuse or circuit
breaker. This should be satisfactory for normal
use, while providing enough protection against
motor damage caused by power surges. Grizzly
recommends that the circuit you use should be
dedicated, (i.e., the G1004 or G1008 should pro-
vide the only draw from that circuit). If frequent
circuit failures occur when using the milling
machine, contact our service department or your
local electrical contractor. You are cautioned that
equipment returned to us for service that shows
evidence of being over-fused will be repaired or
replaced totally at the customer’s expense,
regardless of the present warranty status.
We do not recommend the use of extension cords
on 220V equipment. It is much better to arrange
the placement of your equipment and the
installed wiring to eliminate the need for exten-
sion cords. Should it be necessary to use an
extension make sure the cord is rated Hard
Service (grade S) or better.

Grounding
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric
shock. This tool must be equipped with an elec-
tric cord having an equipment-grounding conduc-
tor which must be properly connected to a
grounding plug. The plug must be plugged into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
