Initial Assembly
Warning
Do not operate saw until fully assembled.
Installing the Cutting Head
Remove the three screws (part# G4) from the mounting flange of the frame assembly and set them aside. From the Cutting Head,
loosen the davies knob (part# B3) and remove the wing nut (part# B5) on the blade guard. Remove the blade guard and set it
aside. With the Cutting Head, align the three screw holes of it”s casting (part# G1) with the mounting screws through the casting
into the saw frame and retighten. Reinstall the blade guard and connect the vinyl water hose to the brass fitting located on the
blade guard.
Installing the Blade
Loosen the davies knob (part# B3) and wing nut (part# B5) on the blade guard. Raise the
blade guard to its highest position and retighten the wing nut. Loosen and remove the
blade shaft nut (part# H6) & outside blade flanges (part# H5) and set them aside. Place
the diamond blade onto the motor shaft against the inside flange. Ensure that the rotation
arrow (stamped onto the steel core of the blade) points “counter-clockwise” when viewed
from the blade side of the saw. Place the outer blade flange against the blade and tighten
the blade shaft nut onto the threaded shaft. DO NOT OVERTIGHTEN. Reposition the blade
guard and tighten fittings. Attach splash guard to back of blade guard with wingscrew and
washer provided.
Installing the Water Pump
The end of the water hose (lying in the water pan) has a 3/8” diameter vinyl sleeve attached. Affix this 3/8” sleeve onto the
spout of the water pump, using the plastic adapter provided. Place the pump anywhere in the water pan. Route the water
pump power cord through the slot in the side of the table as shown. Fill the pan with clean water, and ensure that the water
level is above the intake port of the pump. It is very important to keep the pump’s intake port under water during operations.
Any air introduced to the pump could cause an interruption of water flow. This pump is fully submersible, and you may wish
to place it adjacent to your saw in a bucket of water to provide a continuous flow of clean water to your blade (this helps
extend the life of both blade and pump). Connect the plug end of the water pump into the water pump receptacle located on
the motor. The pump is activated by the ON/Off switch on the electric motor.

Warning
This pump requires the use of a Ground Fault Circuit Interrupter. To reduce risk of electric shock, connect the saw to a Ground
Fault Circuit Interrupter outlet when operating the saw with the pump plugged into the 3-pole receptacle on motor. See the pump
manual and informational tags enclosed separately for all pump information.
Caution
Shock Hazard. For replacement pump, use only identical pump, MK model PES-100, part# 155987.
notice
Do not run the pump dry. Also be sure to disconnect and remove the water pump when cutting dry.
Electrical Requirements and Grounding Instructions
The MK-470 tile saw is wired for 120V, single phase operation, and draws 5.3 amps at 120V. This is not a large load, however
if the machine is operated on any circuit that is already close to its capacity, the circuit breaker may be tripped. If this occurs,
eliminate other loads from the circuit. A separate circuit protected by a 20 amp breaker is ideal. If other loads do not exist and
power failure still occurs, have the circuit inspected by a qualified electrician. If a generator is used, use one rated at 3.5Kw minimum.
Warning
This tool must be grounded. In the event 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.
• Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
• Improper connection of the equipment - grounding conductor can result in a risk of electric shock. The conductor with the
insulation having an outer surface that is green, with or without yellow stripes, is the equipment grounding conductor. 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 qualified 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 damaged or worn cord immediately. See Table 1 for proper extension cord gage requirements.
Warning
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch A in Figure 1. The tool has
a grounding plug that looks like the plug illustrated in Sketch A in Figure 1. 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 when a properly grounded outlet is not available. The temporary
adapter should be used only until a properly grounded outlet can be installed by a qualified 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.
Additionally, the water pump requires the use of a Ground Fault Circuit Interrupter. Therefore, when using the water pump plugged
into the water pump receptacle, this tool must be plugged into a properly installed and grounded Ground Fault Circuit Interrupter
outlet, like the one illustrated in Sketch D in Figure 1. If a Ground Fault Circuit Interrupter outlet is not available, MK Diamond has
available, as an accessory item, a plug - in Ground Fault Circuit Interrupter that may be plugged into a properly installed and
grounded 3-pole outlet. See Sketch E in Figure 1.

Extension Cords
Use only extension cords that are intended for outdoor use. These extension cords are identified by a marking of, “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 damaged extension cords, do not “yank” on any cord to disconnect it from the power supply. Keep
cord away from heat and sharp edges. Always disconnect the extension cord from the receptacle before disconnecting the product
from the extension cord.
Warning
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch plug with wet hands.
Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the tile saw.
Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
Table 1
Minimum gage for cord
Use of undersize extension cords results in low voltage to the motor, which 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 customer’s expense, there will be no
warranty claim.
Notice
Warning
If the plug or receptacle does get 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.
power
supply cord
To avoid the possibility of the appliance plug or receptacle getting wet, position tile saw to one side of a wall mounted receptacle to
prevent water from dripping onto the receptacle or plug. A “drip loop,” shown in the figure below, 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.
drip loop
Lock Out Method
In order to help prevent accidental starting and to help make your workshop “Kidproof”, this saw is provided
with a means to deactivate the functioning of the motor switch. The switch is provided with a removable
toggle. With the toggle removed the switch does not function, and the motor cannot be turned on. Replacing
the toggle reactivates the switch function. See illustration.
Sawing Operations
General Cutting Guidelines
• A diamond blade does not cut, it grinds. Do not force the tile into the blade, nor feed it to quickly.
• Diamond blades are not all alike. Match the MK blade to the product to be cut.
• Before mounting any blade on the saw, inspect the arbor shaft, flanges and blade for damage or fatigue.
• It is natural for the diamond blade to wear out. Follow MK’s blade recommendations for better longevity and efficiency.
• Check that the directional arrow of your MK blade always points in a counter-clockwise direction as it is mounted.
• Ensure that a continuous flow of water to both sides of the blade occurs during operation.
• Diamond blades need to be sharpened from time-to-time, as this allows for optimum performance. (See optional accessories.)
• Be sure the blade arbor hole diameter matches the blade shaft.
• Never operate any saw without safety guards in place.
• Do not force the blade into the material: allow the blade to cut all its own speed.
• Do not cut dry with blades designed for wet cutting.
• Do not make long continuous cuts with dry cutting blades: allow the blade to cool by turning the air every few minutes.
• Do not exceed the blades safe operating speed.
• Do not operate the saw with a blade diameter larger than the saws capacity.
• Do not cut or grind with the side of the diamond blade, or make radius or curve cuts.

notice
Warning
Do not attempt to cut pieces too small to hold by hand outside the blade guard. Avoid awkward hand positions where a sudden
slip could cause a hand or fingers to come in contact with the blade. When cutting any material, make sure it is fully supported.
Hold workpiece firmly against the fence. Only feed the material as fast as the blade is able to affectively cut. DO NOT FORCE THE
MATERIAL INTO BLADE!
Rip Cutting
Rip cutting is the term used to describe cutting the material flat on the conveyor table. When cutting the
material on the square, position the rip guide to the desired cutting dimension, and tighten the thumb screw
to secure it in place. Firmly hold the material against the conveyor table back stop and the rip guide while
cutting. When cutting diagonally, position the material using the conveyor table back stop and the optional dual
45° flat angle guide. For cutting materials at other angles, use the 0-90° protractor to align material to the desired
angle. (See optional accessories, page 5.)
Warning
square cut
diagonal cut
Do not attempt to cut pieces too small to hold by hand outside the blade guard. Avoid awkward hand positions
where a sudden slip could cause a hand to move into the blade. When cutting a large piece of material, make
sure it is fully supported. Hold workpiece firmly against conveyor table, back stop and guide. Only feed the
material fast enough for the blade to cut. DO NOT FORCE.
Conveyor Table Markings
The markings on the conveyor table back stop are used to aid in cutting tile to particular dimensions. The scale on
the top of the back stop is used for setting the rip guide’s diamond window indicator relative to the exact distance
from the diamond blade to the edge of the rip guide. You must first measure the tile for the cut to act as the
standard, and then use the rip guide & table markings to assist in additional cuts.
Maintenance
For your safety, turn ON/OFF switch “OFF” and unplug saw from the power source before performing any maintenance or cleaning.
If the power cord becomes damaged in any way, replace it immediately with the approved cord. When cleaning the saw, DO NOT
let the motor come in direct contact with water. If excessive moisture is introduced to the motor electrical shock could occur and
can cause damage to the internal parts.
DO NOT Service the motor’s internal parts yourself. Contact an authorized MK Service Center, or MK Diamond’s Factory Service
Center for technical support and parts information 1-800-474-5594 for help in solving any problems.
Periodic maintenance your MK-470 allows for long life and trouble-free operation. The cutting residue that the saw generates could be
considerable. A cleaning, lubrication and maintenance schedule should be maintained.
Required maintenance practices include:
• Clean the saw with fresh water after every use.
• Pump clean/fresh water for (1) minute through the water pump and blade guard assembly to safeguard against slurry build-up and
clogging.
• Inspect the diamond blade for its overall integrity. Check the rim or segment rim for wear or damage.
• Inspect the wear of the electric motor’s (2) carbon/graphite brushes regularly. The brushes are easily accessible by removing
the brush caps with a flat end screw driver from the square top of the motor. Pull the brushes from their holder and change
them when approximately 1/4" of the brush remains. Use only authorized MK parts.
Trouble Shooting
Warning
For your safety, turn the ON/OFF switch “OFF” and unplug the saw from the power source before performing any troubleshooting procedures.
motor problems
