PREVENTING BODY CONTACT WITH GROUNDED SURFACES. For example: pipes, radiators, ranges,

refrigerator enclosures.

n KEEP GUARDS IN PLACE and in working order. Never

operate the tool with any guard or cover removed. Make sure all guards are operating properly before each use.

n REMOVE ADJUSTING KEYS AND WRENCHES.

Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.

n KEEP WORK AREA CLEAN. Cluttered areas and

benches invite accidents. DO NOT leave tools or material on the machine while it is in operation.

n AVOID DANGEROUS ENVIRONMENT. Don't use

power tools in damp or wet locations or expose to rain. Keep work area well lit.

n KEEP CHILDREN AND VISITORS AWAY. All visitors

should wear safety glasses and be kept a safe distance from work area. Do not let visitors contact tool or extension cord while operating.

n MAKE WORKSHOP CHILDPROOF with padlocks or

master switches, or by removing starter keys.

n DON'T FORCE TOOL. It will do the job better and

safer at the feed rate for which it was designed.

n USE RIGHT TOOL. Don't force tool or attachment

to do a job it was not designed for. Don't use it for a purpose not intended.

n MAKE SURE YOUR EXTENSION CORD IS IN GOOD

CONDITION. 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 resulting in loss of power and overheating. A wire gage size (A.W.G.) of at least 14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

n DRESS PROPERLY. Do not wear loose clothing, gloves,

neckties, or jewelry. They can get caught and draw you

into moving parts. Rubber gloves and nonskid footwear are recommended when working outdoors. Also wear protective hair covering to contain long hair.

n ALWAYS WEAR SAFETY GLASSES WITH SIDE

SHIELDS. Everyday eyeglasses have only impact- resistant lenses; they are NOT safety glasses.

n SECURE WORK. Use clamps or a vise to hold work

when practical. It's safer than using your hand and frees both hands to operate tool.

n DON'T OVERREACH. Keep proper footing and balance

at all times.

n MAI N TAIN TO O L S WI T H CA R E. Kee p too l s

n DISCONNECT TOOLS. When not in use, before

servicing, or when changing attachments, wheels, bits, cutters, etc., all tools should be disconnected.

n AVOID ACCIDENTAL STARTING. Be sure switch is

off when plugging in.

n USE RECOMMENDED ACCESSORIES. The use of

improper accessories may cause risk of injury.

n NEVER STAND ON TOOL. Serious injury could occur if

the tool is tipped or if the cutting wheel is unintentionally contacted.

n CHECK DAMAGED PARTS. Before further use of the

tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged must be properly repaired or replaced by an authorized service center to avoid risk of personal injury.

n NEVER LEAVE TOOL RUNNING UNATTENDED.

TURN POWER OFF. Don't leave tool until it comes to

a complete stop.

n PROTECT YOUR LUNGS. Wear a face or dust mask

if the cutting operation is dusty.

n PROTECT YOUR HEARING. Wear hearing protection

during extended periods of operation.

n DON'T ABUSE CORD. Never yank cord to disconnect

GENERAL SAFETY RULES

n NEVER USE IN AN EXPLOSIVE ATMOSPHERE.

Normal sparking of the motor could ignite fumes.

n INSPECT TOOL CORDS PERIODICALLY. If damaged,

have repaired by a qualified service technician at an authorized service facility. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Repair or replace a damaged or worn cord immediately. Stay constantly aware of cord location and keep it well away from the rotating wheel.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known 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.
