6. Adjust with additional shims, as required, until table is level when all mounting screws (or nuts) are tight.

8.0 ELECTRICAL CONNECTIONS

!
All electrical connections must be done by a qualifi ed electrician. All adjustments or repairs must be done with machine disconnected from power source. Failure to comply may cause serious injury.
The Vertical Band Saw is rated at 230/460V and comes from the factory prewired 230V.
You may either connect a proper UL-listed plug suitable for 230 volt operation, or “hard-wire” the machine directly to your electrical panel provided there is a disconnect near the machine for the user.
The band saw must be grounded. A qualifi ed electrician can make the proper electrical connections and confi rm the power on site is compatible with the saw.
Before connecting to power source, make sure switch is in off position.
Fig. 1

7.0 INSTALLATION

For best performance, the band saw should be located on a solid and level foundation. Allow room for servicing and for moving large stock around the band saw when decid­ing a location for the machine.
1. Remove four (4) nuts and washers holding band saw to shipping crate bottom.
2. Use the lifting ring to lift band saw into its permanent location. For best performance, band saw should be bolted to fl oor after a level position has been found.
3. Using a square, adjust table 90 degrees to blade, both front to back and side to side. Loosen the hex cap screws below the table to move it and tighten to hold table in place. If necessary, adjust the pointers to zero should they read different once table is perpen- dicular to blade in both directions.

8.1 VOLTAGE CONVERSION

To switch to 460V operation:
1. Switch the jumper wires on the circuit board. Remove control panel from saw body and change the jumper wires according to the list in section 18.0, Electrical Connections.
2. If a plug is to be used, install a proper UL-listed plug suitable for 460V operation.
IMPORTANT: Consult the diagrams in section 19.0 for any clarifi cation of these changes on 230V to 460V con- version.

8.2 THREE-PHASE TEST RUN

After wiring the band saw, you should check that the wires have been connected properly. Connect machine to power source and turn it on for an instant to watch direction of blade movement.
If blade runs upward instead of downward, disconnect machine from power, and switch any two of the three leads in the motor junction box (see section 19.0, Wiring Diagram).
