Grizzly G0740 Adding Coolant, Power Connection, To connect the power cord to the lathe

In addition to the reservoirs, we also recommend that you lubricate all other points on the machine at this time. This can be accomplished by follow- ing the maintenance schedule on Page 64.

Note: If this lathe was shipped with oil in the res- ervoirs, do not change that oil until after the test run and spindle break-in procedures.

Adding Coolant

Add the coolant of your choice now. For detailed instructions on where the coolant tank is located and how to add fluid, refer to Coolant System Service on Page 70.

Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use an electrician or a qualified service personnel to ensure a safe power connection.

Before the machine can be connected to the power source, an electrical circuit must be made available that meets the minimum specifications given in Circuit Requirements for 220V on Page 15. If a power circuit has not been prepared for the machine, do that now.

To minimize the risk of electrocution, fire, or equip- ment damage, installation work and electrical wir- ing MUst be done by an electrician or qualified service personnel.

Note About Extension Cords: Using an incor- rectly sized extension cord may decrease the life of electrical components on your machine. Refer to Extension Cords on Page 16 for more infor- mation.

Model G0740 (Mfg. Since 11/12)

Note About 3-Phase Power: Due to the startup load from this machine, we do not recommend using a static phase converter to create 3-phase power—as it can quickly decrease the life of electrical components on this machine. If you must use a phase converter, only use a rotary phase converter and connect the manufactured leg or "wild wire" to the S terminal (see location in Figures 22–23). The S terminal can handle power fluctuation because it is wired directly to the motor.

To connect the power cord to the lathe:

1.Press the STOP button, turn the two-speed motor switch to the OFF position then open the electrical cabinet door.

2.Identify the R, S, and T terminals and the grounding terminal (see Figure 22).
