POWER SOURCE

Band saw requires a 115 or 230 volt, 60 Hz power source. Band saw is shipped with motor and controls prewired for 115 volt operation. Line cord does not

have plug. A 115 volt, 20/30A three-prong plug must be attached to the line cord.

The motor is designed for operation on the voltage and frequency specified. Normal loads will be handled safe- ly on voltages not more than 10% above or below the specified voltage.

Running the unit on voltages which are not within

the range may cause overheating and motor burn-out. Heavy loads require that the voltage at motor terminals be no less than the voltage specified. Power supply to the motor is controlled by a double pole locking rocker switch. Remove the key to prevent unauthoriFed use.

GROUNDING INSTRUCTIONS

WARNING: Improper connection of equipment grounding conductor can result in the risk of electrical shock. Equipment should be grounded while in use to protect operator from electrical shock.

Check with a qualified electrician if grounding instruc- tions are not understood or if in doubt as to whether the tool is properly grounded.

Green (or green and yellow) conductor in cord is the grounding wire. If repair or replacement of the electric cord or plug is necessary, do not connect the green (or green and yellow) wire to a live terminal.

Many cover plate screws, water pipes and outlet boxes are not properly grounded. To ensure proper ground, grounding means must be tested by a qualified electrician.

To use the band saw with a 230V power supply: WARNING: All electrical connections must be performed by a qualified electrician.

Have a qualified electrician attach a 230 volt, 20/30A 3-prong plug band saw line cord.

Open cover (Figure 17, Key No. 8) by removing eight pan head screws.

Change wire from 115V terminal of transformer to the unused 230V terminal (See Figure 2).

Change amperage setting on the thermal overload relay (See Figure 2).

Replace cover.
