INSPECTION/SETUP
INSPECTION/SETUP
1. Read and fully understand this manual,
the safety intructions in particular, and
the motor manufacturer's manual supplied
with the saw.
2. Select the correct blade for each application. If abrasive
blades are used, MAKE CERTAIN they are designed
for use on a concrete floor saw. They must be reinforced
and have a hole for the driving pin. When wet cutting
with an abrasive blade, MAKE CERTAIN the blade is
intended for wet cutting. Water will destroy a dry cut
abrasive blade. Some diamond blades require water
cooling and failure to do so will destroy them almost
immediately. Other diamond blades can be used with or
without water. Refer to the Blades and Blade Placement
sections in this manual for further information.
3. Handle all blades with care and NEVER use a damaged
blade. NEVER use an abrasive blade that has been
dropped.
Electric Motor
1. The motor should be connected to a power source in
compliance with all local electrical codes. This must
be performed by a qualified electrician. After this
connection is made, it will be necessary to check the
rotation of the motor shaft. The shaft rotation MUST
be counter-clockwise when viewing the motor from
the shaft extension end. If the rotation of the shaft is
incorrect make the necessary changes for the correct
shaft rotation.
2. MAKE CERTAIN the rated line voltage is at the motor
when cutting. Motors can burn out when the voltage
falls 10% below the voltage rating of the motor. Also
use the correct heavy duty circuit breakers or fuses in
the circuit.
3. MAKE CERTAIN the correct size extension cord is
used. Undersize wires will burn out motors. Use the
following chart to determine the extension cord size.

WARNING
ALWAYS use a grounded extension cord and
make certain the motor is connected to a
properly grounded electrical circuit to protect
the operator from possible electric shock.
DANGER
ALWAYS use a grounded (3-wire) extension cord and
MAKE CERTAIN that the motor is connected to a
properly grounded electric circuit to protect the operator
from possible electric shock.
NEVER touch the power
cord with wet hands or while
standing in water when it is
connected to a power source.
The possibly exists of electrical
shock (electrocution) or even
death. NEVER spray water
directly on the electric motor.
WARNING
NEVER operate the saw without blade guards and
covers in place. DO NOT operate with the front of
the blade guard raised. The blade exposure cannot
exceed 180 degrees during operation. Adhere to the
safety guidelines of the American National Standards
Institute (ANSI) B7.1 and B7.5.
