ASSEMBLY INSTRUCTIONS/OPERATIONS

CAUTION

Operating the SURFACE GRINDER from a power source of improper voltage and amperage will result in un-repairable damage to the electric motor and related controls.

FIGURE 31

4)Providing proper voltage and amperage levels to the electric motor is essential to obtain maximum productivity and service life. Low voltage and amperage levels will cause the motor to overheat. 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.

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 DFG/E Series

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.

DANGER

PROPERLY INSPECT ALL EXTENSION CORDS AND WIRING DEVICES FOR STRUCTURAL INTEGRITY. DO NOT UTILIZE A CORD WITH A WORN OR CUT OUTER JACKET MATERIAL. DO NOT UTILIZE A CORD WITH EXPOSED INNER WIRES OR INSULATION MATERIAL. DO NOT UTILIZE A CORD THAT HAS BEEN REPAIRED WITH ELECTRICAL TAPE. USE OF A AN EXTENSION CORD OF IMPROPER STRUCTURAL INTEGRITY CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.

DANGER

ALL ELECTRICAL WIRING 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.

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
