Voltage Conversion; Extension Cords - Jet HVBS-7MW Operating Instructions And Parts Manual

as shown in B if a properly grounded outlet is
not available. The temporary adapter should be
used only until a properly grounded outlet can
be installed by a qualified electrician. This
adapter is not permitted in Canada. The green-
colored rigid ear, lug, and the like, extending
from the adapter must be connected to a
permanent ground such as a properly grounded
outlet box.
3. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has
an outlet that looks like the one illustrated in D,
Figure 6. The tool has a grounding plug that
looks like the plug illustrated in D. Make sure the
tool is connected to an outlet having the same
configuration as the plug. No adapter is
available or should be used with this tool. If the
tool must be reconnected for use on a different
type of electric circuit, the reconnection should
be made by qualified service personnel; and
after reconnection, the tool should comply with
all local codes and ordinances.

6.7 Voltage conversion

The HVBS-7MW band saw is rated at 115/230V
and comes from the factory prewired at 115V.
To switch to 230V operation, follow the wiring
diagram found on the inside of the motor
junction box. (Similar diagrams are shown in
Figures 7/8.) The plug must be replaced with a
plug that is rated at 230V. The coolant pump
wiring will have to be changed also. Follow the
diagram found on the coolant pump head to
switch to 230V operation.
Before hooking up to the power source, be sure
the power and coolant switches are in the off
position.

6.8 Extension cords

The use of extension cords is discouraged. Try
to position machines within reach of the power
source. If an
necessary, make sure the cord is in good
condition and heavy enough to carry the current
your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows correct
size to use depending on cord length and
nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge
number, the heavier the cord.
