GENERAL SAFETY PRECAUTIONS AND HAZARD SYMBOLS
In order to prevent injury, the following safety precautions and symbols should be followed at all times!
SAFETY PRECAUTIONS
KEEP GUARDS IN PLACE
In order to prevent injury, keep guards in place and in working order at all times.
EXPLOSIVE FUEL!
Gasoline is extremely ammable, its vapors can explode if ignited; store only in approved containers, in well-ventilated, unoccupied buildings and away from sparks or ames. Do not ll the fuel tank while the engine is running
or hot. Spilled fuel could ignite if it contacts hot parts or sparks from ignition. Do not start the engine near spilled
fuel. Never use gasoline as a cleaning agent.

MK-5000G SAFETY
LETHAL EXHAUST GASES!
Engine exhaust gasses contain poisonous carbon monoxide, an odorless colorless gas that can cause
death if inhaled. Avoid inhaling exhaust fumes, and never run the engine in a closed building or conned
area.
ELECTRICAL SHOCK!
Never touch electrical wires or components while the motor is running. Exposed, frayed or worn electrical motor wiring can be sources of electrical shock that could cause severe injury or burns.
ENGINE OVER-SPEED.
Never tamper with the governor components or settings to increase the maximum speed of the machine. Severe personal injury and/or equipment damage could result if the equipment is operated speeds above design
maximum.
ACCIDENTAL STARTS!
Before starting the engine, be sure the ON/OFF switch is in the “OFF” position to prevent accidental starting.
Place the ON/OFF switch in the OFF position before performing any service operation.
ROTATING OR MOVING PARTS!
Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate a power tool
with shrouds or guards removed.
HOT PARTS!
Engine components can become extremely hot from operation. To prevent severe burns, do not touch these
areas while the engine is running, or immediately after it is turned off. Never operate the engine with heat
shields removed.
ALWAYS USE SAFETY GLASSES!
Exhaust gases may be harmful if inhaled. Do not operate gas-powered equipment in enclosed spaces. Respiratory protection should be worn when operating gas powered equipment.
ALWAYS USE RESPIRATORY PROTECTION!
Safety glasses should always be worn when working around power tools. Everyday eyeglasses only have
impact resistant lenses and may not prevent eye injury; they are NOT safety glasses.
ALWAYS USE HEARING PROTECTION!
To reduce the possibility of hearing loss, always use hearing protection when operating equipment.
REMOVE ADJUSTING KEYS AND WRENCHES.
Form a habit of checking to see that keys and adjusting wrenches are removed from the power tool before it is turned on.
KEEP WORK AREA CLEAN.
Cluttered work areas and benches invite accidents.
DO NOT USE IN DANGEROUS ENVIRONMENTS.
Do not operate equipment in dangerous environments. Always keep the work area well lighted.
5
Page 6
MK-5000G SAFETY
KEEP CHILDREN AWAY.
All visitors and children should be kept a safe distance from work area.
MAKE 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.
WEAR PROPER APPAREL.
Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may be caught in moving parts.
Nonslip footwear is recommended. Wear protective hair covering to contain long hair.
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 sharp and clean for the best and safest performance. Always follow maintenance instructions for lubricating
and when changing accessories.
SHUTDOWN TOOL.
The saw should always be shutdown before servicing or when changing accessories such as blades, bits, cutters, and
the like.
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.
NEVER LEAVE TOOL RUNNING 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.
CHECK FOR DAMAGED PARTS.
Before using a power tool, check for damaged parts. A guard or any other part that is damaged should be carefully
checked to determine it would operate properly and perform its intended function. Always check moving parts for
proper alignment or binding. Check for broken parts, 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.

MK-5000G SAFETY
SILICA DUST WARNING
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 addition, 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.
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain 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.

MK-5000G 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”
Types of Cutting
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 Dia-
mond 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.
