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

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.

I. PREPARATION
C. Assembly Conveyor Cart & Guide-a-Cut
Conveyor Cart Assembly:
Remove the Conveyor Cart and Back Stop from the Saws Water Pan, and the
Wing Nuts, Carriage Bolts, Washers, and Cart Stop from the plastic bag. Slide
one (1) Carriage Bolt thru each of the three (3) Square Holes located on the
front of the Conveyor Cart. Slide the Back Stop Over each of the Carriage
Bolts. Slide the Stop Assembly over the Carriage Bolt Located on the Left front
of the Conveyor Cart NOTE: The Rubber Stop will faces away from the
Conveyor Cart. Attach one (1) Washer and one (1) Wing Nut to each Carriage

Figure 2: Guide-A-Cut Assembly
Splash Assembly:
Remove the Splash Guard from the Saw Water Pan. Attach the Splash Guard
Spring Clips to the Pivoting Bar Located Under the Cutting Head. Note that the

Splash Guard material is made is designed for easy to cleaning. To clean,
simply rinse the Splash Guard with water until clean. The Splash Guard should
be used when wet cutting to reduce the amount of debris thrown from the blade
and cutting surface. When dry cutting the Splash Guard can be removed to
allow the dust particles to drift away from the Saw Operator.

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 h.p. and 7-1/2 h.p. 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.
Voltage Selection for Single Phase Motors 3 h.p. Single phase masonry saw
motors have' an * optional dual voltage switch so that 115 volt or 230-volt power
supply can be used with no change in wiring. Wherever possible, use 230 volt
power supply for best operation. To change voltage, remove the screw on the
motor voltage toggle switch, and set the toggle switch knob to the connected
operating voltage .
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 for 3 and 5 h.p. single phase motors:
Length Of Wire
Wire Gauge 3 HP 115-Volt 3 &5 HP 230-Volt
12 -NA- 50’
10 25’ 100’
08 50’ 150’
06 75’ -NA-
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.
