DIAMOND BLADE SAFETY

  • Use appropriate steel centered diamond blades manufactured for use on concrete cutters.
  • 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 cutter.
  • 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.

CUTTER TRANSPORTATION SAFETY

  • Use the lifting bail and appropriate lifting equipment to ensure the safe movement of the cutter.
  • DO NOT use the handle bars and/or front pointer as lifting points.
  • NEVER tow the saw behind a vehicle.
  • Ensure that both pointer bars are positioned appropriately to minimize their exposure during transportation.
  • Safeguard against extreme cutter attitudes relative to level. Engines tipped to extreme angles may cause oil to gravitate into the cylinder head making the engine difficult to start.
  • NEVER transport the cutter with the blade mounted.

EMERGENCIES

  • ALWAYS know the location of the nearest fire extinguisher and first aid kit. Know the location of the nearest telephone. Also know the phone numbers of the nearest ambulance, doctor and fire department. This information will be invaluable in the case of an emergency.

  • ALWAYS allow the machine a proper amount of time to cool before servicing.
  • Keep the machinery in running condition.
  • Fix damage to the machine immediately and always replace broken parts.
  • Dispose of hazardous waste properly. Examples of potentially hazardous waste are used motor oil, fuel and fuel filters.
  • DO NOT use food or plastic containers to dispose of hazardous waste.

OPERATION

Introduction/Determining the Right Machine

Congratulations on your purchase of our Cutter! You’ve made an excellent choice! Our floor cutter has been specifically designed as the ideal machine for the professional contractor who is engaged in concrete and asphalt flat sawing. The machines used for the primary purpose of “flat” sawing. This type of sawing 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.
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. Our MF16 utilized for jobs requiring precision cutting including floors, pavements, walkways, ramps and other flat sawing applications. You will find a cutter 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.

OPERATING PRINCIPLE
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.

DELIVERY CHECKS
Immediately upon taking delivery of your new equipment and before putting it into service:

  • Read the handbook completely–it could save a great deal of unnecessary expense.
  • Read the engine manual supplied.
  • Check the general condition of the equipment–has it been damaged during delivery?
  • Check engine oil level.
  • Check fuel levels.

Recommend lubricants are detailed in the CARE AND MAINTENANCE section.

INSTALLING 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 flange.
  3. Clean off any foreign particles on the clamping surfaces of flanges 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 flange 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 flange, 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 specifications are available for cutting concrete or asphalt.

BEFORE STARTING

  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.

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.

  • 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 flooding. Always operate the engine at full throttle when under load.

  • Hot 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.
    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.
    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.

TO START CUTTING

  1. Start engine and let engine warm up. All cutting is done at full throttle.
  2. Align blade and cutter with cut. If wet cutting, open water valve and turn water safety switch on.
  3. Lower blade into cut slowly.
  4. Cut as fast as blade will allow. If blade climbs out of cut, reduce forward speed or depth of cut.
  5. Use only enough side pressure on cutter handles to follow cutting line.

CUTTING
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.

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.
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.

BELTS & PULLEYS
NEVER MAKE ADJUSTMENTS TO V-BELTS AND PULLEYS WHILE ENGINE IS RUNNING.

  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:
    • The engine drive shaft and the blade shaft are not parallel.
    • 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.

DRY CUTTING

  • Never operate any saw without safety guards in place.
  • Do not exceed maximum operating speed established for blade diameter.
  • Do not force blade into material: allow blade to cut at its own speed.
  • Do not make long continuous cuts. Never dry cut for more than 30 seconds at a time. Allow blade to cool.
  • Do not cut or grind with side of blade or cut a curve or radius.  Do not cut dry with blades recommended for wet cutting.
  • Do not operate saw with blade diameter larger than machine’s capacity.
