Electric Motor

The BBM307/YBM307 Block Buster Mini Masonry Saw electrical information:

Motor Specifications:

Voltage: 115-volt

Cycles: 60Hz

Amperage: 14Amp

Horsepower: 3HP Peak

Watts: 2,238 watt

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 in the following table. The

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 Block Buster Mini Masonry Saw should be connected to 115-volt 60 Hertz electrical supply with a

minium of a 15 amp circuit. For best results use a 20 amp circuit. Using the machine with the improper

electrical supply can result in motor damage and is not covered under warranty.

Generator:

For best results use a generator that has a continuous output that is greater than 4,000 watts (4kW).

Using the machine with a generator that is less than the recommend output can result in motor damage

and is not be covered under warranty.

Electrical Safety

For safety and security concerns the operator should lockout the power switch when the machine is not

in use.

Ground Fault Circuit Interrupt (GFCI)

This machine requires the use of a Ground Fault Circuit Interrupt (GFCI) device.

Grounding:

Do not modify the plug as provided- if it will not fit the outlet, have the proper outlet installed by a

qualified electrician.

Improper connection of the equipment-grounding can result in a risk of electric shock. The conductor

with insulation having an outer surface that is green with or without yellow stripes is the equipment-

grounding conductor. If repair or replacement if the electric cord or plug is necessary, do not connect the

equipment-grounding conductor to a live terminal. Check with a qualified electrician or service personal

if the grounding instructions are not completely understood, of in doubt as to whether the tool is properly

grounded. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles

that accept the tool’s plug. Repair or replace damaged or worn cord immediately.
