6) The Floor Grinder utilizes a factory supplied extension
cord equipped with an integral GFI device. The GFI
device is intended to protect both the operator and
electric motor in the event a ground fault is developed
during operation. The extension cord is 37 foot (11 m)
long, fabricated from 12 AWG wire and incorporates
a NEMA 5-15P plug and a NEMA L5-15R twist lock
receptacle. The twist lock feature allows the extension
cord to be pulled by the Floor Grinder without becoming
disconnected.
BEFORE USE, PROPERLY INSPECT THE
EXTENSION CORD AND WIRING DEVICES FOR
STRUCTURAL INTEGRITY. DO NOT UTILIZE A
CORD WITH A WORN OR CUT OUTER JACKET
MATERIAL. DO NOT UTILIZE A CORD THAT HAS
BEEN REPAIRED WITH ELECTRICAL TAPE. DO
NOT UTILIZE A CORD WITH A CRACKED AND/
OR DAMAGED GFI CASE. USE OF AN EXTENSION
CORD OF IMPROPER STRUCTURAL INTEGRITY
AND/OR DAMAGED GFI CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
ALL ELECTRICAL WIRING, INCLUDING EXTENSION
CORD GAUGE WIRE SIZE AND/OR LENGTH,
MUST BE INSTALLED AND/OR APPROVED IN
ACCORDANCE TO LOCAL ELECTRICAL CODES
AND PRACTICES.AN IMPROPER WIRING
INSTALLATION CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
7) Determine that the power source receptacle to be
utilized is properly grounded. This can be accomplished
with proper testing equipment and procedures. If there
are any questions regarding the suitability of a specific
power receptacle, contact your dealer or our Customer
Service Department for assistance bEFoRE utilizing
the Floor Grinder. There is no charge for this service.
8) If additional extension cord length is required for
a specific job application, an additional extension
cord can be utilized in conjunction with an external
GFI. Plug the receptacle of the additional extension
cord into the factory supplied GFI. Plug the ground
fault circuit interrupter into a separate power source
receptacle. Connect the extension cord plug into the
external GFI. This configuration will allow any fault over
the length of a defective extension cord to be indicated.
Extension cord gauge size and length must conform to
National Electric Code standards.
FOR MAXIMUM PROTECTION AGAINST A FAULT,
ALWAYS CONFIGURE A GROUND FAULT CIRCUIT
INTERRUPTER TO BE PLUGGED INTO THE POWER
SOURCE RECEPTACLE. A CONFIGURATION WITH
THE GROUND FAULT CIRCUIT INTERRUPTER
PLACED BETWEEN THE FLOOR GRINDER AND
THE POWER SOURCE RECEPTACLE WILL NOT
AFFORD MAXIMUM PROTECTION AGAINST A
POTENTIAL FAULT.
9) Couple the NEMA L5-15R receptacle of the factory
supplied extension cord and the NEMA L5-15P plug
located on the Floor Grinder together. Twist to lock.
FIGuRE 15. Connect the GFI to the power source
receptacle. Determine that the reset switch is in its
proper position to activate the GFI.
