I. PREPARATION
A. Safety Precautions
Important! The following safety precautions must always be observed.
Hazard Symbols
Fuel (gasoline) is extremely flammable and its vapors can explode if ignited.
Store gasoline only in approved containers, in well-ventilated, unoccupied
approved areas, and away from sparks or flames. Do not fill the fuel tank
while the engine is hot or running. Do not start the engine near spilled fuel.
Never use the fuel as a cleaning agent
Engine components can get extremely hot from operation. To prevent burns,
do not touch the engine or related parts while the engine is running or
immediately after it is turned off. Never operate the engine with any heat
shields or guards removed.
Keep all guards in place when operating any piece of equipment
Keep hands, feet, hair, and clothing away from all rotating parts
Lethal Exhaust Gas use only in well ventilated areas. Engine exhaust gases
contain poisonous carbon monoxide, which is odorless, colorless, and can
cause death if inhaled. Avoid inhaling exhaust fumes, and never run the
engine in a closed building or confined area
Never tamper with the governor components of settings to increase the
maximum speed. Severe personal injury and damage to the engine or
equipment can result if operated at speed above maximum. Always obey the
maximum speed rating of blade.
DO NOT LIFT THE SAW BY THE HANDLE BARS

5
Dust and Silica Warning
Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust,
mists and fumes containing chemicals known to cause serious or fatal injury or illness, such as
respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar with
the risks associated with the particular process and/or material being cut or the composition of
the tool being used, review the material safety data sheet and/or consult your employer, the
material manufacturer/supplier, governmental agencies such as OSHA and NIOSH and other
sources on hazardous materials and make certain to comply with all product warnings and
instructions for the safe and effective use of the material being cut. California and some other
authorities, for instance, have published lists of substances known to cause cancer,
reproductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work
practices and follow the recommendations of the manufacturer/supplier, OSHA/NIOSH, and
occupational and trade associations. Water should be used for dust suppression when wet
cutting is feasible. When the hazards from inhalation of dust, mists and fumes cannot be
eliminated through engineering controls such as either vacuum and/or water mist, the operator
and any bystanders should always wear a respirator approved by NIOSH/MSHA for the
material being cut.
California Proposition 65 Message
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contain chemicals known (to the State of California) to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
• Lead, from lead-based paints
• Crystalline silica, from bricks and cement and other masonry products
• Arsenic and chromium, from chemically treated lumber

1. Before mounting any blade on the saw, the blade should be inspected for any damage
which might have occurred during shipment, handling or previous use.
2. The blade collars and arbors should be cleaned and examined for damage before
mounting the blade.
3. The blade must be properly fitted over the arbor with the drive pin on the outside
collar projecting through the drive pinhole on the blade and inside collar.
4. The blade shaft nut, which is a left-hand thread nut, must be tightened securely
against the outside blade shaft collar.
5. The blade must be operated within the specified maximum operating speed listed on
the blade.
6. Turn water control valve to full to provide adequate coolant (4 to 6 gallons per
minute) for diamond blades and wet cutting abrasive blades. Insufficient coolant
could result in severe blade breakage or diamond segment separation.
7. The blade guard must be in place with the nose guard down and locked when the saw
is running.
8. The operator should wear safety glasses and any other appropriate safety equipment.
9. When starting the saw, the operator should stand away and to the side of the blade.
10. If for any reason the saw should stall in the cut, raise the blade out of the cut. Check
the outside blade shaft collar and nut for tightness. Inspect the blade for damage
before restarting the saw. Use caution when resuming a cut. Be certain that the
blade is in alignment with the previous cut.
11. During cutting operations, do not exert excess side pressure on the handles as a
method of steering. Do not force the blade into the cut by lowering the blade too fast
or by pushing the saw too fast.

I. PREPARATION
D. Electrical Connections
Important-Before connecting the motor leads to the power supply be sure that the
voltage, cycles and phase shown on the nameplate of the motor correspond to the
available power supply.
Voltage Selection For Single Phase Motors
1-1/2 HP and 2 HP single phase masonry saw motors have a dual voltage capable. A 115-volt
or 230 volt power supply can be used. To change voltage simply move the voltage change
switch located on the front of the motor to the required voltage, no rewiring is required.
Wherever possible, use 230-volt power supply for best operation.
BBC307 3 HP models are 230 volt only.
Failure to run the motor on the proper voltage will damage the motor and is not
covered under warranty. Improperly wired motors are not covered under warranty.
BBC157 & BBC207 models are wired for 115 Volt from the factory!!!
Power Connections
Connect the power supply to the pigtail leads of the switch. Direct wiring connection is
preferred, but an extension cord with an electrical plug with 30-amp minimum capacity may be
used. A 30-amp circuit breaker is recommended. Connecting wires should be as short as
possible and in one piece. In no case should the connecting wires be longer than shown in the
following table for 1-1/2, 2, and 3 HP. Single-phase motors:
Length Of Wire
Wire gauge 115 volt 230 volt
12 AWG 50’ (15m)100’ (30.4m)
10 AWG 50’ (15m)150’ (45.7m)
Caution-When wires that are too small gauge or too long are used, loss of power, over
heating, or possible damage to the motor will result. For the best performance and cost
use a 10 AWG 50 foot (15 meter) extension cord.
Always use the proper wiring connectors that are UL/CSA approved to attach the
motor to the electrical supply. Any wiring hook ups should be made by qualified
personal and made to National Electrical Code and to any Local Codes.
Generators:
If a generator must be used, it must be of 8kW or larger. The generator must have a 30A
circuit and capable of providing a minimum of 8kW at the required voltage. Under size
generators will cause motor damage and is not covered under warranty.
