Jet Tools J-3410 Uncrating and spotting the saw, Electrical, To change the operating voltage

Machine Set-up

The saw delivered to you has been adjusted at the factory. A number of test pieces have been cut using the saw to verify the accuracy of cutting.

Therefore, the only set-up operations required before releasing the saw for service are spotting the saw and establishing the electrical connections to the motor.

If ordered with the coolant kit, the kit is typically installed at the JET factory. However, if the kit is ordered separately by you, it must be installed by a set-up mechanic, so instructions for this task are included in this Machine set-upsection, as well.

Uncrating and spotting the saw

Spot the saw where it makes the most sense for the operations you will probably be doing. If you are going to be doing cut-off work on very long pieces of stock, allow plenty of room for the stock, infeed and outfeed supports, etc.

Remove the saw from the shipping skid and discard any hold-down devices which might have secured the saw to the skid.

Note the lock plate on the arm of the saw which is secured under the bump rubber. This lock plate must be removed before the saw arm can be raised. You may discard the lock plate and cap screw used to hold it in place. Be sure, however, to replace the nut on the bottom of the horizontal stop.

Electrical

The saw is delivered as either a 115 volt or 230 volt saw, depending upon your order. Wiring diagrams for either type of circuit are shown here.

The motor is connected, internally, to achieve the voltage set-up required. However, you can change the motor's internal wiring connections to change the operating voltage, if necessary.

To change the operating voltage

1.Disconnect the saw from its electrical power source.

2.Open the motor plate. The requirements for

either 115 or 230 volt connection will be seen on a diagram inside the motor plate.

3.After making the connections, close the motor plate.

4.If you are using a plug connection to a socket, you will need to use the appropriate plug for the new power source supplying the saw, then plug the cord into the supplying receptacle to reconnect power to the saw.

5.If you are hard wired to a junction box, connect to the wires in the box, close the box, and reestablish power to the branch.

6.The saw is now ready for service.

Note: JET recommends that any wiring involving hard wiring of the saw to a branch, or any change of voltage supplied to the motor, be performed by a licensed electrician.

Note: also --- if the coolant kit is installed on the Model J-3410 saw is prewired for 115 volt operation . When changing the motor voltage to 230 volts, the coolant pump must be changed to 230 volt following Figure-20 or the wiring diagram on the pump lable.
