Page 5
MK-145 SAFETY
KEEP CHILDREN AWAY
All visitors and children should be kept a safe distance from work area.
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 rst. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage that will result in a loss of power and
overheating. TABLE 1, Page 9 shows the correct AWG size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.
USE PROPER APPAREL
DO NOT wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may be
caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering
to contain long hair.
ALWAYS wear approved eye protection.
ALWAYS wear approved respiratory protection.
SECURE WORK
Clamps or a vise should be used to hold work whenever practical. Keeping your hands free
to operate a power tool is safer.
DO NOT OVERREACH
Keep proper footing and balance at all times by not overreaching.
MAINTAIN TOOLS WITH CARE
Keep tools clean for the best and safest performance. Always follow maintenance
instructions for lubricating, and when changing accessories.
DISCONNECT TOOLS
Power tools should always be disconnected before servicing or when changing accessories,
such as blades, bits, cutters, and the like.

Page 6
MK-145 SAFETY
ON / OFF
ALWAYS place the power ON/OFF switch in the OFF position when the saw is not in use
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. A guard or any other part that is
damaged should be carefully checked to determine if would operate properly and perform
its intended function. Always check moving parts for proper alignment or binding. Check
for broken parts and mountings and all other conditions that may affect the operation of the
power tool. A guard, or any damaged part, should be properly repaired or replaced.
DIRECTION OF FEED
ALWAYS feed work into a blade or cutter against the direction of rotation. A blade or cutter
should always be installed such that rotation is in the direction of the arrow imprinted on the
side of the blade or cutter.
NEVER LEAVE A TOOL UNATTENDED
TURN POWER OFF - Do not leave a tool until it comes to a complete stop. Always turn a
power tool OFF when leaving the work area, or when a cut is nished.
CALIFORNIA PROPOSITION 65 MESSAGE

MK-145 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. 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 t the outlet; have the proper outlet installed
by a qualied 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 qualied 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. The tool has a grounding plug that looks like the plug illustrated in Sketch A. 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
qualied 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.

MK-145 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
Drip Loop Information
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.
WARNING
Use only extension cords that are intended for outdoor use. These extension cords are
identied 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 damaged 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. Keep cords 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 the plug with wet hands. 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. There will be no warranty claim.
To choose the proper extension cord,
• Locate the length of extension cord needed in the table below.
• Once the proper length is found, move down the column to obtain the correct AWG
size required for that length of extension cord.
EXTENSION CORD MINIMUM GAGE FOR LENGTH
VOLTS TOTAL LENGTH OF CORD IN FEET

MK-145 MAINTENANCE
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 will become smoothed or “glazed” over. This will reduce grinding
efciency 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. The diamond blade can be dressed using the
MK Dressing Stick (part number 152792) and by following the steps below.
(A)
Setup the MK-145
for operation
(D)
Set Blade Guard above the
top of the Dressing Stick

MK-145 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. As a result, a diamond blade for cutting soft, abrasive material must have a hard
metal matrix composition to resist this erosion long enough for the exposed diamonds to be properly
utilized. Conversely, a blade for cutting a hard, non-abrasive material must have a soft bond to
ensure that it will erode and expose the diamonds embedded in the matrix. These simple principles
are the foundation of “controlled bond erosion”.
TypesofCutting:
There are two basic types of cutting-Dry or Wet. The choice of which type of blade to use depends on
• The requirements of the job
• The machine/tool utilizing the diamond blade
• The preference of the operator
In the case of DRY cutting, the overwhelming popularity and quantity of hand-held saws and the
exible nature of MK Diamond blades to professionally handle most ceramic, masonry, stone and
concrete materials, make the DRY cutting blade a very attractive tool. When using a DRY blade, the
user must be aware of distinct operating practices to ensure optimum performance. DRY cutting
blades require sufcient airow about the blade to prevent overheating of the steel core. This is best
accomplished by shallow, intermittent cuts of the material with periods of “free-spinning” (for several
seconds) between each cut, to maximize the cooling process.
For WET cutting applications, MK has the exact blade to compliment both the material to be cut
and the wet cutting machine to be used. During cutting operations, liberal amounts of water act as
a coolant to support the cutting effectiveness and longevity of the WET blade. Additionally, using
water adds to the overall safety of cutting operations by keeping the dust signature down.
Know all you can about the material you wish to cut.
