SECTION 2: CIRCUIT REQUIREMENTS

110/220V Operation

Serious personal injury could occur if you connect the machine to the power source before you have completed the setup pro- cess. DO NOT connect the machine to the power source until instructed to do so.

Amperage Draw

The Model G9749 features a 110/220V motor that is prewired for 220V and draws the following amps under maximum load:

Motor Draw at 110V	16	Amps
Motor Draw at 220V	8	Amps

Circuit Requirements

We recommend connecting your machine to a dedicated and grounded circuit that is rated for the amperage given below. Never replace a circuit breaker on an existing circuit with one of higher amperage without consulting a qualiﬁed electri- cian to ensure compliance with wiring codes. If you are unsure about the wiring codes in your area or you plan to connect your machine to a shared circuit, consult a qualified electrician.
