The MK-370 _le Sow is a versatilecur,r.ingmachinedesigned to use diamond blades. Its funcuonis to cut
a variety of materials to include ceramics and certain types of stone. The MK-370 is compactand
lighweight, and incorporetos features found on larger progfessional models. This saw is engineeredas a
self-contained unit consisting of a powerful universal motor, removeable water reservoir and water
recirculating system, and quality diamond blade. The motor operates on standard 115V current, and the
water pump is convenientlyenergizedby the motor.

replacement of the electric cord or plugis necessary,donot connectthe equipment- groundingconductorto a liveterminal.
• Checkwith a qualified electricianor servicepersonnelif the grounding instructions are not completelyunderstood,or if in doubt
as to whether the tool is properly grounded,
• Use only3-wire extensioncordsthat have 3-preng groundingplugs and 3-pole receptacles that accept the tool's plug.
• Repair or replace damaged or worn cord immediately, SeeTable1 for proper extensioncord gage requirements.
This toolis intendedfor use on a circuitthat has anoutlet that looks like the one illustrated in Sketch A in Figure 1. l_e tool has

General Cutting Guidelines
•Adiamond bladedoes not cu_. it grinds, Do not force the tile intothe blade, nor feed it to quickly.
• Diamond blades arenot airalike.March the MK blade to r_e product to be cut,
•Beforemounting anybladeon the saw, inspect the arbor shaft, flanges andblade for damage or fatigue.
• It is natural for the diamondbladeto wear out. Follow MK's bladerecommendations for better longevityendefficiency.
•Oled< that the diractional arrowof yourMK blade always points in acounter-clockwise direction as it is mounted.
• Ensure that acontinuousflow 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 opUmum performance. [See optional
accessories.)
• Be sure the blade arbor hole diameter matchesthe blade shaft.
• Never operate any saw without sefecyguardsin place,
• Do not force the bladeinto the material: allowthe blade to cut all it's ownspeed.
• Do not cut dry with blades designedfor wet cutting.
• Oonot make long continuouscurs with dry cuttingblades: allowthe blade to cool by turning the air everyfew minutes.
• Do not exceedthe blades safe operating speed.
• DOnotoperate the saw witha bladediameter larger than the sawscapacity. 5
• Do nat cut or grindwiththe sideof the diamondblade, or make radiusor curvecuts.

RIp Cutting
Rip cutting is the term usedto describe cutting the material flat on the conveyor table. When cutt,_ngthe
:material on the square, position the rip guide to the desired cuttingdimension,and tighten the thumb screw
to secure it in place. Firmly hold the material against; r_e conveyor table back stop end the rip guide while

Do not atr.emptto cut pieces _o small to hold byhand outside the blade guard. Avoid awkward handpositions
where asudden slip could causea hand to move into the blade, When cutrJng alarge piece of material, make
sure it is fully supported. Hold workplace firmly against conveyortable, back stop and guide. Only feed the
material fast enoughfor the bladeto cut. DO NOTFORCE.
TableMarkings
Themarkings on the table back stop are usedto aid in cutting tile to particular dimensions. The scale onthe top of
the back stop is used for setting the rip guide's diamond window indicator relative to the exact distance from the
diamondblade to the edgeof the rip guide.You must firscmeasure the tile for the cut to act as the standard, and
then use the rip guide & table markJngsto assist in additional outs.
Maintenance
For your safety, turn ON/QFF switch "OFF' and unplugsaw from the power source before performing any maintenance or
cleaning.
If the power cord becomes damaged in anyway, replace io immediately with the approved cord When cleaning the sew, O0
NOTlet the motor come in direct contactwith water. If excessivemoisture is introduced to the motor electricalshockcould
occur andcan cause damage to the internalparts.
