4) The motor is equipped with automatic thermal protection
device that will stop it before major internal damage
can result. After the motor has cooled to an acceptable
temperature level, the switch must be manually
activated to restart. FIGURE 32.

To minimize the voltage drop to the motor, all extension
cords should be copper stranded, 8 AWG or larger. A
NEMA 6-20R twist-lock type receptacle is provided with
the SFG10E SURFACE GRINDER as a standard
accessory. The twist clock feature allows the extension
cord to be pulled by the SURFACE GRINDER without
becoming detached. Wire the NEMA 6-20R receptacle
to the appropriate extension cord that will be coupled
to the NEMA 6-20P plug provided on the SURFACE
GRINDER. FIGURE 33.

NOT UTILIZE A CORD WITH A WORN OR CUT OUTER
JACKET MATERIAL. DO NOT UTILIZE A CORD WITH
EXPOSED INNER WIRES OR INSULATION MATE-
RIAL. DO NOT UTILIZE A CORD THAT HAS BEEN
REPAIRED WITH ELECTRICAL TAPE. USE OF A AN

ALL ELECTRICAL WIRING MUST BE INSTALLED
AND/OR APPROVED IN ACCORDANCE TO LOCAL
ELECTRICAL CODES AND PRACTICES. AN IM-
PROPER WIRING INSTALLATION CAN RESULT IN
PROPERTY DAMAGE AND/OR PERSONAL INJURY.
5) Determine that the power outlet 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 outlet,
contact the Customer Service Department for
assistance BEFORE utilizing the SURFACE GRINDER.
There is no charge for this service. A qualified electrician
can also be consulted. If a 115 VAC power outlet is
selected, it is recommended that a properly tested,
externally mounted, ground fault circuit interrupter
(GFCI) be utilized at all times as an additional safety
precaution. FIGURE 34.
