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 OR

GUARDS!!!

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

I. PREPARATION

E. 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. Both the 5 HP and 7-1/2 HP. motors have overload

protectors and are equipped with a reset button on the motor housing. If, after

proper electrical connections are made, the motor will not run, press the reset

button to the overload protector switch. The optional 575v and 600v Three (3)

Phase motors do not have a thermal over load protector.

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.

Voltage Selection for Three (3) Phase Motors 5 and 7-1/2 HP 230-480v:

Wherever possible, use 480v power supply for best operation. To change

voltage, disconnect the power form the machine, remove the terminal box cover

from the top of the motor, and change the connections as shown in the wiring

diagrams on page 12 or the chart below.

Line A Line B Line C Join Join Join Join Join Join

High (480v) 1 2 3 4,7 5,8 6,9 10 11 12

Low (230v) 1,7 2,8 3,9 10,4 11,5 12,6 – – –

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. 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:

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.

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 personnel and made

to National Electrical Code and to any Local Codes.
