SECTION 2: CIRCUIT REQUIREMENTS

110V Operation

Grounding

The Model G4000 is wired for 110 volt, single phase operation only. The 3⁄4 HP motor will safely draw 12 amps at 110V. A 15-amp fuse or circuit breaker should be used when connecting this metal lathe. Circuits rated any higher are not ade- quate to protect the motor.

If you operate this lathe on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist and a power failure still occurs, contact a qualified electrician or our ser- vice department.

Equipment returned to us for service that shows evidence of being over-fused will be repaired or replaced totally at the customer’s expense, regardless of the present warranty status.

Extension Cords

If you find it necessary to use an extension cord with the Model G4000, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instructions to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric cur- rent. This tool is equipped with a power cord hav- ing an equipment-grounding conductor. See Figure 1. The outlet must be properly installed and grounded in accordance with all local codes and ordinances.

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually ground- ed. If it is not, it will be necessary to run a separate 12 A.W.G. copper grounding wire from the outlet to a known ground. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.
