115 Volt Operation
The VBS-18MW band saw is wired from the
factory for 115 volt operation. The power cord
has a
plug that looks like A, Figure 1, and is
used in an outlet that looks like B, Figure 1. A
temporary adapter with a grounding ear secured
with a screw (C, Figure 1) may be used to
connect this plug to a two-pole receptacle if a
properly grounded outlet is not available. The
temporary adapter should only be used until a
properly grounded outlet can be installed by a
qualified electrician.
This adapter is not
applicable in Canada. The green colored
grounding ear , lug, or tsab, extending from the
adapter, must be connected to a permanent
ground such as a properly grounded outlet box,
as shown in C, Figure 1.
Figure 1
It is recommended that the Band Saw when
operated at 115 volts , be connected to a
dedicated, minimum 30 amp circuit with a 30
amp circuit breaker or time delay fuse. Local
codes take precedence over recommenda-
tions.
230 Volt Operation
If 230V, single phase operation is desired, the
following instructions must be followed:
1. Disconnect machine from the power source.
2. This band saw is supplied with four motor
leads that are connected for 115V operation.
For 230V operation, re-connect the leads as
shown in the diagram inside the motor
junction box. The diagram is replicated on
page 40 of this manual.
3. The 115V attachment plug supplied with the
band saw must be replaced with a UL/CSA
listed plug suitable for 230V operation,
similar to that shown in Figure 2. Contact
your local Authorized JET Service Center or
qualified electrician for proper procedures to
install the plug. The band saw must comply
with all local and national codes after the
230V plug is installed.
4. The band saw with a 230V plug should only
be connected to an outlet having the same
configuration (Figure 2). No adapter is
available or should be used with the 230V
plug.
Figure 2
It is recommended that the Band Saw when
operated at 230 volts , be connected to a
dedicated, minimum 15 amp circuit with a 15
amp circuit breaker or time delay fuse. Local
codes take precedence over recommend-
dations.
Important: In all cases (115 or 230 volts), make
certain the receptacle in question is properly
grounded. If you are not sure, have a registered
electrician check the receptacle.
Extension cords
The use of an extension cord is not
recommended for this band saw; try to position
the machine within reach of the power supply. If
an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine’s motor plate. An undersize cord
will cause a drop in line voltage resulting in loss
of power and overheating.
Use the chart in Figure 3 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
