Extension Cords:
Most motor trouble
is the result of too small gauge or
too long of extension
cord.
Cords must be one piece and as short as
possible.
Cords should be no longer than shown on
Table 2: Extension Cord Maximum Length Chart.
Norton Construction Products is not responsible for
damage to motors due to the use of extension cords that
are too small or too
long.
For safety and security concerns the operator should lockout the power switch when the
machine is not in use. Verify the model number of the machine and select the correct
wiring diagram before preforming any maintenance or service.
Ground Fault Circuit Interrupt (GFCI)
The BBM307 and BBM158 do not include a Ground Fault Circuit Interrupt (GFCI) device. If a GFCI is
required, please order the following from your Norton Clipper distributor. The 70184633009 GFCI is
designed to attach to the BBM’s power in cord and the power supply, if using an extension cord
always connect the GFCI to the power source, then attach the extension cord (see Extension Cord
section of this manual for details on the cord set), and then attach the BBM to the Extension cord.
DO NOT place the GFCI between the Extension Cord and the machine as it will trip a GFCI.
