Introduction/Determining the Right Machine
The machines used for the primary purpose of “at” sawing. This type of sawing is described as “at”
because the pavement is cut somewhere close to a horizontal plane. It is the most common type of
diamond blade cutting. Concrete cutters in the industry are available in a variety of types, sizes and styles,
they range from manual or self propelled in horsepower from 7-72hp. It is possible to cut both concrete
(green or cured, with or without rebar) or asphalt with a concrete cutter.
INSTALLING THE BLADE
1. Be certain that the spark plug is disconnected or saw is unplugged.
2. Remove the blade shaft nut and take off outside blade shaft ange.
3. Clean off any foreign particles on the clamping surfaces of anges and on the mounting surface of the
blade.
4. Place the blade on the blade shaft,lining up the offset drive pin in the blade with the drive pin in the
mounting collar (if the pin system is available on the machine). If your blade has a directional rotational
arrow, position arrow for down cut (diamond tail trailing for down cut).
5. Replace the outside blade shaft ange on the blade shaft. Drive pin on the inside collar must project
through the drive hole in the blade and into the outside collar (if the pin system is available on the machine).
6. Tighten the blade shaft nut securely against star washer and outside ange, using wrench supplied.
7. Reconnect the spark plug or (with switch “off”) plug in the electric supply cord.
Types of Cutting
Cut speed depends entirely on using the correct blade for the material to be cut. Wet or dry, diamond
blades of various specications are available for cutting concrete or asphalt.
Before Starting/Cold Start/Hot Start
BEFORE STARTING
1. Use correct blade for cutting conditions.
2. Ensure arbors and anges are clean and undamaged.
3. Mount blade and tighten securely using wrench.
4. When wet cutting, check water jets for adequate ow.
4. Align pointer with cutter blade.
CAUTION: Set unit up in en open area. Avoid close proximity to structures or other equipment. Failure to
do so may cause Inadvertent injury to operator or other persons in the area.
COLD START: Open the fuel valve under the gas tank all the way. Position the engine stop switch located
on the engine, to run. Open the throttle approximately half way and apply the choke. Pull the starter rope
sharply. When the engine starts, open the choke and adjust the throttle as necessary to keep it running.
Allow the engine to warm up for a few minutes before placing it under the load If the engine doesn’t start
after (3) pulls open choke slightly to prevent ooding. Always operate the engine at full throttle when under
load.
