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

ALWAYS read this Owner’s Manual before operating the machine.

ALWAYS keep the Guards in place.

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 PLACES

DO NOT use power tools in damp or wet locations nor expose them to rain. Always
keep the work area well lighted.

KEEP CHILDREN AWAY

All visitors and children should be kept a safe distance from work area.

MK-1503SS 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. 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 10 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.

ON / OFF

DISCONNECT TOOLS

Power tools should always be disconnected before servicing or when changing
accessories, such as blades, bits, cutters, and the like.

ALWAYS place the power ON/OFF switch in the OFF position when the tool is not in use.

MK-1503SS 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. 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 finished.

CALIFORNIA PROPOSITION 65 MESSAGE

WARNING

Some dust created by power sanding, polishing, 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/SLTC/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.

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. Severe personal injury and damage to the engine or equipment can result if
operated at speeds above maximum.

DO NOT EXPOSE TO RAIN

DO NOT expose to rain or use in damp locations.

WARNING

Polishing and drilling generates dust. Excessive airborne particles may cause irritation to eyes, skin
and respiratory tract. To avoid breathing impairment, always employ dust controls and protection
suitable to the material being polished or drilled; See OSHA (29 CFR Part 1910.1200). Diamond
Blades improperly used are dangerous. Comply with American National Standards Institute Safety
Code, B7.1 and, Occupational Safety and Health Act covering Speed, Safety Guards, Flanges,

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

qualied 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 qualied 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 qualied 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.
