Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following require- ments:

Minimum Gauge Size at 110V

12 AWG

Minimum Gauge Size at 220V

14 AWG

Maximum Length (Shorter is Better)

50 ft.

Voltage Conversion

The voltage conversion MUST be performed by a qualified electrician. To perform the voltage conversion, replace the power cord, install the correct plug, and rewire the motor to the new volt- age, according to the provided wiring diagram on Page 52.

Note: If the diagram included on the motor con- flicts with the one in this manual, the motor may have changed since the manual was printed. Use the diagram provided inside the motor wiring junc- tion box.

To convert the machine to 110V:

1.DISCONNECT MACHINE FROM POWER!

2.Replace the power cord with one that match- es the cord specifications under Circuit Recommendations for 110V on Page 9.

3.Replace the 6-15 plug on the power cord with a NEMA 5-20 plug.

4.Re-wire the motor as illustrated in the wiring diagram.

Disabling & Locking

Switch

The ON/OFF switch can be disabled and locked by inserting a padlock through the ON button, as shown. Locking the switch in this manner can prevent unauthorized operation of the machine, which is especially important if the machine is not stored inside an access-restricted building.

IMPORTANT: Locking the switch with a padlock only restricts its function. It is not a substitute for disconnecting power from the machine when adjusting or servicing.

Children or untrained people can be seriously injured by this machine. This risk increases with unsupervised operation. To help prevent unsupervised operation, disable and lock the switch before leaving machine unattended! Place key in a well- hidden or secure location.

NOTICE

The padlock shaft diameter is important to the disabling function of the switch. With any padlock used to lock the switch, test the switch after installation to ensure that it is properly disabled.
