MK-SDG 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 saw is not in use.
5
Page 6
MK-SDG 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.
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, 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.

MK-SDG 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-SDG 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 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.
