MK-170 TILE SAW Safety MAKE THE WORKSHOP KID PROOF Make the workshops kid proof by using padlocks, master switches or by removing starter keys. DO NOT FORCE THE TOOL A power tool will do a job better and safer operating at the rate for which it was designed. USE THE RIGHT TOOL DO NOT force a tool or an attachment, to do a job that it was not designed to do. USE THE PROPER EXTENSION CORD If using an extension cord make sure it is in good condition first.
MK-170 TILE SAW Safety USE RECOMMENDED ACCESSORIES Consult the owner’s manual for recommended accessories. Using improper accessories may increase the risk of personal or by-stander injury. NEVER STAND ON THE TOOL Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally contacted. CHECK FOR DAMAGED PARTS Before using a power tool, check for damaged part.
MK-170 TILE SAW Safety n Hazard Symbols ELECTRICAL SHOCK NEVER touch electrical wires or components while the engine is running. They can be sources of electrical shock which could cause severe injury or burns. ROTATING PARTS Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate the motor with covers, shrouds, or guards removed. (( )) OVER SPEED NEVER tamper with the governor components or settings to increase the maximum speed.
MK-170 TILE SAW Safety ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be followed at all times! WARNING 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.
MK-170 TILE SAW Safety WARNING 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 the picture 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.
MK-170 TILE SAW Safety WARNING To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands. WARNING Use of under sized 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 customer's expense.

MK-170 TILE SAW (J) Dispose the contents of the Water Pan NOTE: MAINTENANCE (K) Clean the MK-170 with soap and clean water (L) Clean the Water Pan To extend the life of the MK-170, lubricate the Motor Shaft with light oils such as, 3 in 1, WD-40, etc.
MK-170 TILE SAW MAINTENANCE Blade Dressing Like most cutting instruments, a diamond blade performs best when it is dressed. Over time and use, diamonds on the outer edge of the blade will become smoothed or "glazed" over. This will reduce grinding efficiency and may cause the blade to "wander" or bend giving the illusion of an alignment problem. When this occurs, the blade will need to be dressed.
MK-170 TILE SAW MAINTENANCE Motor Brush Change-out WARNING Disconnect the tool before servicing and when changing accessories, such as blades, bits, cutters, and the like.

(C) Ensure the Blade Core is not bent and Arbor is not out of round (B) Remove the pump suction screen and clean the Water Pump of a all debris. (C) Remove the Cooling Transfer Tube from the Blade Guard inlet. Inspect for blockage. (D) Verify the blade is correct for the material being used.
MK-170 TILE SAW (D) Remove the Blade Guard Intake Fitting. TROUBLESHOOTING (E) Clean the Blade Guard Intake Fitting. (F) Locate the Blade Guard Cooling Channels. (B) Verify all plugs are fully connected. (C) Check to see if the Ground Fault Circuit Interrupter (GFCI) is tripped. (G) Rod Cooling channels and recheck flow. Blade Stops Turning (A) Check the ON/OFF Switch is in the ON position.
MK-170 TILE SAW (D) Verify the circuit breaker is at least 20 amps - if not, more to 20-amp circuit. TROUBLESHOOTING (E) Verify circuit breaker not tripped; if it is tripped, reset it once only. 26 (F) Check power source voltage is 120V - if not 120V, move another circuit.

MK-170 TILE SAW THEORY THEORY OF DIAMOND BLADES Diamond blades do not really cut; they grind the material through friction. Diamond crystals, often visible at the leading edge and sides of the rim/segment, remove material by scratching out particles of hard, dense materials, or by knocking out larger particles of loosely bonded abrasive material. This process eventually cracks or fractures the diamond particle, breaking it down into smaller pieces.
