GENERAL SAFETY PRECAUTIONS AND HAZARD SYMBOLS

SAFETY PRECAUTIONS

In order to prevent injury, the following safety precautions and symbols should be followed

at all times!

GENERAL SAFETY

DO NOT operate or service this equipment before reading this entire manual.

This equipment should not be operated by persons under 18 years of age.

NEVER operate this equipment when not feeling well due to fatigue, illness or taking

medicine.

NEVER operate this equipment under the inuence of drugs or alcohol.

Whenever necessary, replace nameplate, operation and safety decals when they become
difcult to read.

ALWAYS store equipment properly when it is not being used. Equipment should be stored

in a clean, dry location out of the reach of children.

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. Never operate the machine in an explosive atmosphere.

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 conned area.

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.

MK-X1318 SAFETY

on

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

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 RESPIRATORY PROTECTION

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 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.

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.

6

MK-X1318 SAFETY

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, etc...

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 func-

tion. 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-X1318 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.

CALIFORNIA PROPOSITION 65 MESSAGE

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.

8

MK-X1318 PRE-START

Before starting the machine, ALWAYS check that all guards are in position and correctly tted. Check

the machine for loose bolts before starting.

Keep area around the machine clear of obstructions which could cause persons to fall onto moving parts.
ALWAYS ensure that the machine is on level ground before using. Know how to stop the machine
quickly in case of emergency. NEVER try to stop a moving blade with your hands.

• NEVER disconnect any “emergency or safety devices”. These devices are intended for

operator safety. Disconnection of these devices can cause severe injury, bodily harm or
even death! Disconnection of any of these devices will void all warranties.

• Unauthorized equipment modications will void all warranties. Manufacturer does not
assume responsibility for any accident due to equipment modications.

• NEVER use accessories or attachments, which are not recommended by MK Diamond for

this equipment. Damage to the equipment and/or injury to user may result.

WARNING

DO NOT use woodcutting, or carbide blades on this machine! Use ONLY Diamond blades on machine.
