SAFETY WARNINGS
SILICA DUST WARNING:
Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition
may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay,
granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline
silica can cause serious or fatal respiratory diseases, including silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a substance known to cause cancer. When cutting such
materials, always follow respiratory precautions.
CALIFORNIA PROPOSITION 65 MESSAGE:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain
chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
•Lead, from lead-based paints
•Crystalline silica, from bricks and cement and other masonry products
•Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:
http://www.osha.gov/SLTC/silicacrystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.html
Your risk from these exposures varies depending on how often you do this type of work.To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment,
such as those dust masks that are specially designed to lter out microscopic particles.

ELECTRIC MOTOR SAFETY
For maintenance care and operation of the electric motor, refer to your electric motor instruction booklet
furnished with the electric motor.
Protect the electric motor from dust as much as possible and keep ventilating openings clean.
Electric Motor Connection
ALWAYS make certain that the power source required for the electric motor is correct and always use the
correct NEMA conguration plug. Motors can burn out when the line voltage falls 10% below the voltage rat-
ing of the motor. Failure to use proper voltage will cause the motor to overheat. Make certain that the correct
size grounded (3-wires) extension cord is used. See the table below.
•
•
DO NOT spray water on the electric motor. Do not touch the plug with wet hands. To reduce
the risk of electrocution, keep all connections dry and off the ground.
DO NOT operate electric motor in an explosive environment.
CAUTION

In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols
should be followed at all times!
In case of a malfunction or breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances.

ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS
WARNING
Do not modify the plug provided – if it will not t the outlet; have the proper outlet installed by a qualied
electrician.
Improper connections of the equipment-grounding conductor can result in a risk of electric shock. The
equipment-grounding conductor is the insulated conductor that has an outer surface that is green, with or
without yellow stripes. If repair or replacement of the electric cord or plug is necessary, do not connect
the equipment-grounding conductor to a live terminal.
Check with a qualied electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the
tool’s plug.
Repair or replace a damaged or worn cord immediately.
WARNING
This tool is intended for use on a circuit that has an outlet that looks like the one shown in Sketch A of
Figure 2. The tool has a grounding plug that looks like the plug illustrated in Sketch A of Figure 2. A temporary
adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a
2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not available. The temporary adapter
should be used only until a properly grounded outlet can be installed by a qualied electrician. The green-
colored rigid ear, lug, and the like, extending from the adapter, must be connected to a permanent ground such
as a properly grounded outlet box.
NOTE: Use of a temporary adapter is not permitted in Canada.

To reduce the risk of electrocution, keep all connections dry and off the ground.
A Ground Fault Circuit Interrupter (GFCI) should be provided on the circuit(s) or outlet(s) to be used for this
machine. Receptacles are available having built-in GFCI protections and may be used for this measure of safety.
When using an extension cord, the GFCI should be installed closest to the power source, followed by the
extension cord and lastly, the machine.
WARNING
WARNING
The pump requires a GFCI. To reduce risk of electric shock when operating the machine with the pump
plugged into the 3-pole receptacle on the motor, connect the saw to a GFCI outlet. See the pump manual and
informational tags enclosed separately for all pump information.
Fig. 3 Drip Loop Information
To avoid the possibility of the appliance plug or receptacle getting wet, position the machine to one side of
a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A “drip loop,”
shown in Figure 3, should be arranged by the user to properly position the power cord relative to the power source.
The “drip loop” is that part of the cord below the level of the receptacle, or the connector, if an extension
cord is used. This method of positioning the cord prevents the travel of water along the power cord and
coming in contact with the receptacle.
If the plug or receptacle gets wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that
supplies power to the tool. Then unplug and examine for presence of water in the receptacle.

WATER PUMP SYSTEM INFORMATION
NOTICE
The Electric Water Pump is a powerful, thermally protected, self-lubricating, fully submersible unit capable of de-
livering 170 gallons (644 litres) of water per hour. For operator convenience, the pump power cord plugs into the
female receptacle of the motor terminal box, and is automatically activated as soon as the motor is turned to the
“ON” position.
The pump has been designed to operate “WET”, therefore it is advisable to disconnect the pump if the operation
calls for “DRY” cutting.When running wet, the pump should be kept in the water reservoir in a position that per-
mits the scupper to be fully submersed. For optimum performance and longevity, it is best to keep clean water in
the reservoir at all times.
You may wish to immerse your water pump in a drum of fresh water, as to allow clean/unslurried water to cool the
Diamond Blade.This action will keep your machine cleaner and allow the greatest life for your Diamond Blade.

19
Interruption of motor operation caused by the thermal switch indicates the existence of improper or insufcient
power to your electric motor. DOUBLE CHECK YOUR POWER SOURCE!
NOTICE

MK-1080 PAVER SAW OPERATION
MOTOR INFORMATION
Your MK-1080 Paver Saw requires minimum preparation prior to operation. It is advisable, however, to periodi-
cally lubricate those metal components that pivot and rotate and observe three critical areas of concern:
1.
2.
3.
Ensure the proper/recommended Diamond Blade has been selected for the job.
Inspect and ensure the proper electrical power is available for your motor.
Ensure a constant ow of water is generated to the Diamond Blade.
Fig. 25 Thermal Overload Switch
For your own safety, NEVER start the motor until you fully understand the electrical
requirements and standards of your machine and jobsite. When starting the saw, the
operator should stand outside the path of the blade. Read requirements and features
of this saw.
WARNING
ON / OFF
The MK-1080 Paver Saw has not been engineered nor designed to cut materials (ie. steel, wood, etc.) other than
those comprised of ceramic/masonry material such as clay, stone, rock, cinder and masonry brick and block. For
best results, USE ONLY MK DIAMOND BLADES. For assistance in Diamond Blade selection, contact your
distributor or MK Diamond at [phone].
NOTICE
The electric motors used on the MK-1080 have been designed to deliver exceptional power over a long period
of time, with virtually no maintenance requirements. However, if they do NOT receive the proper voltage condi-
tions, their performance and longevity will degrade. Continued operations utilizing dubious power sourcing could
damage your electric motor. If extension cords are necessary, pay particular attention to their length and gauge.
Always be cautious around your jobsite power source!
NOTICE
THERMAL OVERLOAD PROTECTION
The Thermal Overload manual reset switch is located on the top housing of the electrical motor (Figure 25). If
an extreme internal temperature is sensed, the switch will “trip” and the motor will shut off automatically. If this
occurs, turn the motor “ON/OFF” switch to the “OFF” position and allow the motor to cool for at least ten
minutes before restarting. Push the “reset” button (using minimal force) and resume operations.

MK-1080 PAVER SAW OPERATION
CUTTING OPERATIONS
The MK-1080 Paver Saw permits the operator several options for cutting relative to the design of the saw.The
Cutting Head may be adjusted to a xed position for “FORCED” cutting (the action of pushing the material
steadily into the blade). The material may also be “STEP” cut (the process of passing the material while adjusting
the blade to various depths as a means to incrementally cut the piece). Lastly, the “CHOPPING” action of the
saw can be employed to expeditiously “come down onto” and “push through” the material in one motion to
fully utilize the mechanics of the recoil spring /rolling conveyor cart. Whatever the preferred technique, please
follow these general guidelines:
1.
2.
3.
4.
Hold the material rmly against the conveyor cart backstop. Use the rip guide provided to support and
orient the material.
DO NOT force the material into the blade! Allow the diamonds to do the grinding.
When using a brand new diamond blade, make the rst few cuts slowly until the blade is “broken-in” and
cuts freely and easily.
After continuous cutting of very hard and dense materials, the blade’s cutting efciency may slow down.
Should this occur, it can be sharpened by making several passes against very abrasive material such as: soft
cinder block or lightweight sandstone. ENSURE PLENTY OF WATER IS USED DURING THIS
PROCESS!
WARNING
DO NOT operate saw without the blade guard in place. The exposed area of the blade should never exceed
180 degrees during operation. When installing the blade, ensure that the blade and anges are free of sediment,
so the t between ange and blade is even and true.
NOTICE
A Diamond Blade actually grinds...it does not cut. Not allowing the blade to perform the way it was engineered
may result in premature blade wear, diamond “glazing”, steel core warpage, or severe segment damage.
CLEANING & LUBRICATION
The slurry and cutting residue generated by the MK-1080 Paver Saw is considerable. A cleaning and lubrica-
tion schedule must be maintained in order to ensure long and trouble-free operation. As a common sensible
and preventative maintenance practice, clean the dirt and cutting deposits from your machine after each use.A
pressurized spray system may be used, however, never spray around the electric motor, switch box, or ON/OFF
switches. Further, the following lubrication points are advised:
•
•
•
Place light machine oil where friction, pivoting or rotation occurs between the structural components.
DO NOT OIL THE MOTOR!
Pump clean/fresh water for one minute through the Blade Guard Water Tubes to safeguard against a build
up of sediment and the possibility of clogging.
Rotate the entire Cutting Head Assembly on the Pivot Shaft and lubricate where the casting and shaft make
contact.
