SAFETY PRECAUTIONS

5
MK-101-24 SAFETY
MAKE THE WORKSHOP KID PROOF
Make the workshop 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 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.
ALWAYS place the power ON/OFF switch in the OFF position when the saw is not in use.

MK-101-24 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 ifwould 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.
WARNING
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 and
• 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 filter out microscopic particles.
CALIFORNIA PROPOSITION 65 MESSAGE

MK-101-24 SAFETY
In order to prevent potential electrical shock and injury, the following electrical safety precautions and
symbols should be followed at all times!
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
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 electri-
cian. 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-101-24 SAFETY
Drip Loop Information
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 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
identified 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 disconnectingthe product from the extension cord.
WARNING
Use of under sizedextension 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.
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not
touch the plug with wet hands.
