MK-1080 PAVER SAW SAFETY
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 ad-
dition, 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.
SILICA DUST WARNING
CALIFORNIA PROPOSITION 65 MESSAGE
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-
tain 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/dsg/topics/silicacrystalline/index.html
http://www.cdc.gov/niosh/consilic.html
http://oehha.ca.gov/prop65/law/P65law72003.html
http://www.dir.ca.gov/Title8/sub4.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.

9
To choose the proper extension cord:
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.
• 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
MK-1080 PAVER SAW SAFETY

WARNING
Use only extensions cords that are intended for outdoor use. These extension cords are identied
by a marking, “Acceptable for use with outdoor appliances; store indoors while not in use.” Use only
extension cords having an electrical rating not less than the rating of the product. Do not use dam-
aged extension cords. Examine extension cords before using and replace if damaged. Do not abuse
extension cords and do not yank on any cord to disconnect. Always disconnect the extension cord
from the receptacle before disconnecting the product from the extension cord.
WARNING
• Locate the length of extension cord needed
in table to the right.
• Once the proper length is found, move
down the column to obtain the correct
AWG size required for that length of
extension cord.
Use of undersize extension cords result in low voltage to the motor that can result in motor burnout
and premature failure. MK Diamond warns that equipment returned to us showing signs of being run
in a low voltage condition, through the use of undersized extension cords will be repaired or replaced
totally at the customers expense. There will be no warranty claim.
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 rating 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.

MK-1080 PAVER SAW SAFETY
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 cur-
rent to reduce the risk of electric shock. This tool is equipped with an electric cord having an equip-
ment-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 1. The tool has a grounding plug that looks like the plug illustrated in Sketch A of Figure 1. A
temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to con-
nect this plug to a 2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not avail-
able. 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.
Shock Hazard. For replacement, use only an identical pump.
NOTE: Do not run pump dry. Also, be sure to disconnect and remove the pump when cutting dry.
CAUTION
Fig. 2 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 2, 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 exten-
sion 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 ca-
pable of delivering 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.
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.
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 permits the scupper to be fully submersed. For optimum performance and longevity, it is best
to keep clean water in the reservoir at all times.

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 SET-UP
MOTOR INFORMATION
• 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.
(A)
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 conditions, their performance and longevity will degrade. Continued operations utilizing dubious
power sourcing could damage your electric motor. If extension cords are necessary, pay particular atten-
tion to their length and gauge. Always be cautious around your jobsite power source!
NOTICE
The Thermal Overload manual reset switch is located on the top housing of the electrical motor (Fig-
ure 24). 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 mo-
tor to cool for at least ten minutes before restarting. Push the “reset” button (using minimal force) and
resume operations.
Your MK-1080 Paver Saw requires minimum preparation prior to operation. It is advisable, however, to
periodically lubricate those metal components that pivot and rotate and observe three critical areas of
concern:

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. Hold the material rmly against the conveyor cart backstop. Use the rip guide provided to support
and orient the material.
2. DO NOT force the material into the blade! Allow the diamonds to do the grinding.
3. When using a brand new diamond blade, make the rst few cuts slowly until the blade is “broken-in”
and cuts freely and easily.
4. 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 per-
form 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
lubrication schedule must be maintained in order to ensure long and trouble-free operation. As a com-
mon 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.
