SECTION 2: CIRCUIT REQUIREMENTS

110V Operation

The Model H4378 is wired for 110V and will draw

2.5amps. The Model H4379 is wired for 110V and will draw 3.5 amps. If you operate this machine 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 elec- trician or our service department.

A 10 amp dedicated circuit should be used with this grinder. Always check to see if your current wires are capable of handling a 10 amp load. If you are unsure, consult the advice of a qualified electrician.

Extension Cords

If you find it necessary to use an extension cord with the Model H4378/H4379, 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 dam- aged.

Grounding

In the event of an electrical short, grounding reduces the risk of electric shock by providing electric current a path of least resistance. This tool is equipped with a power cord having an equipment-grounding conductor. See Figure 1B. The outlet must be properly installed and ground- ed in accordance with all local codes and ordi- nances.

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no cir- cumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.
