SECTION 2: CIRCUIT REQUIREMENTS

110/220V Operation Grounding

The Model G1183/1276 is prewired for 110V, sin- gle phase operation. Figure 1 depicts the typical grounded receptacle which should be used. This machine can be rewired to operate at 220V, how- ever a different plug will need to be installed. Figure 2 shows a typical 220V plug. A wiring dia- gram is provided at the back of the manual to show the two wiring configurations.

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.

Fusing

The 1 HP motor will draw 12 amps at 110V and 6 amps at 220V. A 15-amp fuse or circuit breaker should be used when fusing this combination sander. Circuits rated any higher are not ade- quate to protect the motor from power surges. If you operate this sander on any circuit that is already close to capacity, it might trip the breaker or blow the fuse. However, if an unusual load does not exist, and the circuit protection is still activated, you should have the circuit inspected by a qualified electrician.
