FLOOR SAW TRANSPORTATION SAFETY
• ALWAYS store equipment properly when it is not being used. Equipment should be stored in a clean, dry location out of
the reach of children.
• NEVER operate this cutter in areas that contain combustible material or fumes. Fire and/or explosions may result from
errant sparks from the equipment.
• Use appropriate steel centered diamond blades manufactured for use on Floor Saws.
• ALWAYS inspect diamond blades before each use. The blade should exhibit no cracks, dings, or flaws in the steel
centered core and/or rim. Center (arbor) hole must be undamaged and true.
• Examine blade flanges for damage, excessive wear and cleanliness before mounting blade. Blade should fit snugly on
the shaft and against the inside/outside blade flanges.
• Ensure that the blade is marked with an operating speed greater than the blade shaft speed of the saw.
• Only cut the material that is specified by the diamond blade. Read the specifications of the diamond blade to ensure
the proper tool has been matched to the material being cut.
• ALWAYS keep blade guards in place. Exposure of the diamond blade must not exceed 180 degrees.
• Ensure that the diamond blade does not come into contact with ground or surface during transportation. DO NOT drop
the diamond blade on ground or surface.
• The engine governor is designed to permit maximum engine speed in a no-load condition. Speeds that exceed this limit
may cause the diamond blade to exceed the maximum safe allowable speed.
• Ensure that the blade is mounted for proper operating direction.
• Use the lifting bail and appropriate lifting equipment to ensure the safe movement of the saw.
• DO NOT use the handle bars and/or front pointer as lifting points.
• NEVER tow the saw behind a vehicle.

INTRODUCTION/DETERMINING THE RIGHT MACHINE
OPERATING PRINCIPLE
Congratulations on your purchase of our saw! You’ve made an excellent choice! Our floor saw has been specifically
designed as the ideal machine for the professional contractor who is engaged in concrete andasphalt flat cutting.
The machines used for the primary purpose of “flat” cutting.
This type of cutting is described as “flat” because the pavement is cut somewhere close to a horizontal plane. It is the
most common type of diamond blade cutting.
Floor saws 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 floor
saw. Our saw utilized for jobs requiring precision cutting including floors, pavements, walkways, ramps and other flat
sawing applications.
You will find a saw to fit a wide variety of job applications.
Upon receipt of your machine, CAREFULLY CHECK FOR ANY FREIGHT DAMAGE. Any damage should be immediately reported
to the carrier and a claim registered.
The following instructions were compiled to provide you information on how to obtain long and trouble free use of the unit.
Periodic maintenance of this unit is essential. Read the manual in its entirety and follow the instructions carefully. Failure
to do so may injure yourself or a bystander.

Cut speed depends entirely on using the correct blade for the material to be cut. Wet or dry, diamond blades of various
specifications are available for cutting concrete or asphalt.
TYPES OF CUTTING
1. Use correct blade for cutting conditions.
2. Ensure arbors and flanges are clean and undamaged.
3. Mount blade and tighten securely using wrench.
4. When wet cutting, check water jets for adequate flow.
5. Align pointer with cutter blade.
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 flooding. Always operate
the engine at full throttle when under load.
NOTE:
These starting instructions are general guidelines only. Since many engine options are available, consult the
Engine Manual included with this unit for specific instructions.
BEFORE STARTING
COLD START
Open the valve under the gas tank all the way if it has been shut off. Open the throttle approximately half way. Do not
apply the choke. Pull the starter rope sharply until the engine starts. When the engine starts, adjust the throttle. Always
operate the engine at full throttle when under load.
1. Start engine and let engine warm up. All cutting is done at full throttle.
2. Align blade and saw with cut. If wet cutting, open water valve and turn water safety switch on.
3. Push and guide the saw manually using the handles. This machine is not self-propelled and does not have powered
forward or reverse travel. Keep both hands on the handles and maintain full control of the saw while following the cutting
line.
4. Lower blade into cut slowly.
5. Cut as fast as blade will allow. If blade climbs out of cut, reduce forward speed or depth of cut.
6. Use only enough side pressure on saw handles to follow cutting line.
HOT START
TO START CUTTING
OPERATION
CAUTION
Set unit up in an 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.
CAUTION
Gasoline Engines – To improve the engine service life, allow the engine to idle without load for (2) to
(5) minutes before shutting it down. When the idling period is up, use the stop switch located on the
engine and turn it to stop. Close the fuel valve under the gas tank. Engine flooding can occur if the valve
is left open during transport.

CUTTING
BELTS & PULLEYS
NEVER MAKE ADJUSTMENTS TO V-BELTS AND PULLEYS WHILE ENGINE IS RUNNING.
Lower the blade into concrete to required depth by turning the tilt crank counterclockwise. Ease the saw slowly forward.
Slow forward pressure if the saw begins to stall.
Push the saw steadily forward using the front pointer as a guide. Exert enough forward pressure so that the engine/motor
begins to labor, but does not slow down. If the saw begins to stall, retard forward movement until full RPM is restored to
the blade. If saw stalls, raise the blade out of the cut before restarting. Avoid excessive side pressure or twisting of the
blade in the cut.
1. The best tension for a v-belt drive is the lowest tension at which the belts will not slip under full load.
2. Take up tension until the belts are snug in the grooves. Run the drive for about five (5) minutes to “seat” the belts. The
impose the peak load. If the belts slip, tighten them until they no longer slip at peak load. Most new belts will need
additional tensioning after seating.
3. Remember, too much tension shortens belt and bearing life.
4. Check the belt tension frequently during the first day of operation. Check the belt tension periodically thereafter and
make any necessary adjustments.
5. The two most common causes of sheave misalignment are:
a) The engine drive shaft and the blade shaft are not parallel.
b) The pulleys are not located properly on the shafts.
6. To check alignment, use a steel straight edge. See Figure 1.
7. Line up the straight edge along the outside face of both
pulleys shown in the drawing. All pulleys have (2) set screws
in the bottom of their grooves. Set screws require thread
locking lock title.
8. Misalignment will show up as a gap between the pulley
face and straight edge. Make sure there is clearance between
arbor pulley and saw base on both sides.
NOTE:
For deeper cuts (4 inches/102mm or more), several cuts should be made in incremental steps of 1-1/2 inch
(38mm) to 2 inches (51mm) until the desired depth is reached.
