Grounding

 

 

 

 

 

 

The Model G1066/G1066Z/G1079 features 220V single-phase motors. The G1066/G1066Z 5 HP motor will safely draw about 25 amps under load. The G1079 2 HP drum motor requires 12 amps for safe operation. All sanders feature 1/4 HP feed motors that draw approx. 3 amps under load.

The Model G1066/G1066Z should be fused at 30 amps. The Model G1079 should be fused at 15 amps. Make sure the wiring in your circuit is rated to handle the amperage draw from your machine. If frequent circuit failure occurs when using the sander, contact our Service Department. The sander must be connected to its own dedicated circuit and should not share a circuit with any other machine. A standard 2-pole breaker is nec- essary for use with the sander.

We recommend using a NEMA-style L6-30 plug and outlet for the Model G1066/G1066Z, and an L6-15 for the Model G1079. You may also “hard- wire” the sander directly to your panel, provided you place a disconnect near the machine. Check the electrical codes in your area for specifics on wiring requirements.

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 an electric cord that has an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper connections of the electrical-grounding conductor can result in the risk of electric shock. The conductor with green or green and yellow striped insulation is the electrical-grounding con- ductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

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.
