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-up
section, 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 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 label.
