110V Operation

The SHOP FOX® W1688 can also be operated at 110 volts (refer to the wiring diagram on Page 38. You will need a NEMA-style 5-20 plug and receptacle as shown in Figure 8. The motor is rated at 11⁄2 HP and draws approximately 16 amps. Use an outlet with a 20 amp circuit break- er or fuse. Remember other machines using the same circuit as this machine add to the total electrical load applied to the circuit. Add up the amperage load ratings of all machines on the cir- cuit. If this total amperage load exceeds the amperage rating of the circuit breaker or fuse, use a different circuit with a higher amperage rating.

DO NOT modify an existing low-amperage circuit by only replacing the circuit breaker with a breaker rated for a higher amperage. The break- er and the complete circuit must be replaced by a qualified electrician.

Extension Cords

We do not recommend using an extension cord with 110V equipment. Using extension cords with an undersized gauge or one that is too long, generates heat in the cord that may cause fire or circuit damage. If you must use an extension cord, use the guidelines below and TABLE 3 to determine the correct cord length and gauge. The amp rating of the motor is 16 amps while wired for 110V and can be found on the motor- data plate.

•Use a cord rated for Hard Service (Grade S) •Use a cord that is 100 feet or less only •Use a cord with a NEMA-style 5-20 plug •Use only undamaged cords

Grounding

Any electrical outlet and cir-

cuit that you plug your

machine into must be grounded. Serious injury and/or fire may occur if this warning is ignored!

Ground this machine! The electrical cord sup- plied with the Model W1688 does not come with a 110 volt plug. Use a plug with a ground pin as shown in Figure 8. If your receptacle does not accommodate a NEMA 5-20 plug with a ground pin, have the receptacle replaced by a qualified electrician or have an appropriate adapter installed and grounded properly.

NOTICE

Make sure when using an adapter, the adapter is grounded.

Remember, an adapter with a grounding wire does not guarantee the machine will be ground- ed. A ground source must always be verified in the electrical circuit within the wall or conduit.
