ASSEMBLY INSTRUCTIONS/OPERATIONS
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. Ground fault circuit interrupters are not available for operation on 230 VAC. FIGURE 34.

DANGER
FOR MAXIMUM PROTECTION AGAINST A FAULT, ALWAYS CONFIGURE THE GROUND FAULT CIRCUIT INTERRUPTER TO BE PLUGGED INTO THE EXTENSION CORD. A CONFIGURATION WITH THE GROUND FAULT CIRCUIT INTERRUPTER PLACED BETWEEN THE POWER SOURCE AND THE EXTENSION CORD WILL NOT AFFORD MAXIMUM PROTECTION AGAINST A POTENTIAL FAULT.
6)Couple the NEMA
7)Grasp the operator handle with firm gripping. When starting the electric motor, apply a down force directly to the operator handle to help reduce the amount of machine weight against the work surface. Turn the ON/OFF switch to the ON position. Reduce the amount of applied down force on the operator handle as the electric motor attains its operational speed.
When operating on 115 VAC, the electric motor will require additional starting time to help compensate for the additional starting amperage requirement. This time is usually within two seconds of activating the ON/OFF switch.
8)The DFG/E Series electrically powered SURFACE GRINDER is not equipped with a centrifugal clutch assembly. The electric motor is directly coupled to the
DANGER
AS SOON AS THE ELECTRIC MOTOR HAS STARTED, THE OPERATOR MUST BE IN A POSITION TO ASSUME DIRECT AND FULL CONTROL OF THE SURFACE GRINDER. FAILURE TO ASSUME DIRECT AND FULL CONTROL CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
9)The DFG/E Series electrically powered SURFACE GRINDER is stopped by moving the ON/OFF switch located on the operator handle to the OFF position. For safety considerations, it is also recommended that the extension cord be disconnected from both the SURFACE GRINDER and electric power source whenever the SURFACE GRINDER is not in use on the job site.
STARTING THE DFG/G SERIES GASOLINE POWERED SURFACE GRINDER ON THE JOBSITE.
1)Position the SURFACE GRINDER on a flat and level surface of firm foundation.
2)Refer to the material supplied by the engine manufacturer for the correct starting, operation and stopping procedures.
3)The DFG/G Series SURFACE GRINDER is equipped with a centrifugal clutch assembly. The clutch is designed to engage at approximately 2400 RPM engine speed. Normal operation of the clutch will allow the engine to operate at its designated idle speed without the multi- accessory discs rotating. If the multi- accessory discs rotate below the designated engine idle speed, do not continue to operate the SURFACE GRINDER until the problem has been properly corrected. Consult the Customer Service Department for specific information. There is no charge for this service.
