SECTION 2: CIRCUIT REQUIREMENTS

110V Operation

 

Grounding

 

 

 

 

 

 

The Model G8220 is wired for 110V, single phase operation only. The 1⁄4 HP motor will draw 1 amp at 110V. If you operate this grinder 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 service department.

Fusing

A 15-amp fuse or circuit breaker should be used when connecting this Bench Grinder. Circuits rated any higher are not adequate to protect the motor from power surges.

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.

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.

Extension Cords

If you find it necessary to use an extension cord with the Model G8220, 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.
