Jet Tools HBS-814GH operating instructions Extension cords, Volt Operation

115 Volt Operation

As received from the factory, your band saw is ready to operate at 115 volt power, using an outlet and a plug that look similar to those illustrated in Figure 6.

A temporary adapter, which looks like the adapter illustrated in Figure 7, may be used to connect this plug to a two-pole receptacle as shown, if a properly grounded outlet is not immediately available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician.

The green colored rigid ear, lug or tab, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box, as shown in Figure 7.

Make sure the voltage of your power supply matches the specifications on the motor plate of the Band Saw.

Conversion to 220 Volt

If 220 volt, single phase operation is desired, the following instructions must be followed:

1.Disconnect machine from power source.

2.Open the electrical box and change the position of the fuse from the 115V slot to the 220V slot. An electrical drawing is included inside the electrical box, and is also shown on page 31 of this manual.

3.The 115V attachment plug supplied with the band saw must be replaced with a UL-listed plug suitable for 220 volt operation. The band saw must comply with all local and national codes after the 220 volt plug is installed. The band saw with a 220 volt plug should only be connected to an outlet having the same configuration (Figure 8). No adapter is available or should be used with the 220 volt plug.

Extension cords

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 only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the machine’s plug.

Use the chart in Figure 9 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.
