SAFETY
Read and follow all safety, operating and maintenance instructions. Failure to read and follow these instructions could result in injury or death to you
or others. Failure to read and follow these instructions could also result in damage and/or reduced equipment life.
KEEP GUARDS IN PLACE.
In order to prevent injury, keep guards in place and in working order at all times.
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 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.
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. The smaller the
gage number, the heavier the cord.
WEAR 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.
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.
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 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 finished.
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.
ACCIDENTAL STARTS!
Before plugging the equipment into an electrical outlet, be sure the ON/OFF Switch is in the OFF position to prevent accidental starting. Unplug the
power tool 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 covers, shrouds, or guards
removed.

Sawing 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 sawed or drilled; See OSHA (29 CFR Part 191 0.1200).
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, Mounting Procedures, General Operating Rules, Handling, Storage and General Machine
Conditions.
CALIFORNIA PROPOSITION 65 MESSAGES:
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
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.
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!
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 fit the outlet; have the proper outlet installed by a qualified 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 qualified 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
A Ground Fault Circuit Interrupter (GFCI) should be provided on the circuit(s) or outlet(s) to be used for the Saw. Receptacles are available having
built-in GFCI protections and may be used for this measure of safety.
When using an extension cord, the GFCI should be installed closest to the power source, followed by the extension cord and lastly, the saw.
To avoid the possibility of the appliance plug or receptacle getting wet, position the saw to one side of a wall mounted receptacle. This will prevent
water from dripping onto the receptacle or plug. A "drip loop," 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.
Use only extensions 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 disconnection the
product form the extension cord.
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands.
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.
