BBM158 Electric Motor
Motor Specifications:
Voltage:
115/230 volt
Cycles: 60Hz
Amperage: 15/7.5 Amp
Horsepower: 1.5 HP Peak
Watts:
1,490 kW
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 3: Extension Cord Maximum Length Chart (see above). Norton Construction Products is not
responsible for damage to motors due to the use of extension cords that are too small or too long.
Electrical Supply:
The BBM158 can be used on a 115-volt 60 Hz 1 Phase circuit with a 20-amp breaker, for best
performance use a 30-amp breaker. The BBM158 can also be used on a 230-volt 60 Hz 1 Phase
electrical supply with a 20-amp breaker, for best performance use a 30-amp breaker.
Before connecting the BBM158 to the electrical supply, make sure the
voltage selected on the saw (see Figure: BB158 Dual Voltage Switch)
matches the voltage of the electrical supply. Failure to do so may result
in motor damage and is not covered under any warranty.
Generator:
Using the machine with a generator that is less than the recommend output
can result in motor damage and is not covered under warranty. Only use with
a generator that is capable of continuous put of 4,000 w (4kW) at 20 amps or
greater.
Dual Voltage Switch:
Always turn off the machine before setting the dual voltage switch. Failure to do so will damage the
motor. To change the voltage: Remove the screw, select the desired voltage, and replace the screw
to prevent the switch from being toggled accidentally.
For safety and security concerns the operator should lockout the power switch when the machine is
not in use.
Wiring Diagram:
The BBM307 and BBM158 use different wiring diagrams and electrical systems due to the different
electrical motors the machines have. Be sure to reference the correct wiring diagram for your
machine.
