which can result in severe eye damage. Before beginning power-tool operation, always
wear safety goggles or safety glasses with side shields and a full-face shield, when
needed. We recommend using a wide vision safety mask over eyeglasses or standard
safety glasses with shields. Always use eye protection marked to comply with ANSI Z87.1.
• Somedustcreatedbypowersanding,sawing,grinding,drillingandotherconstruction
activities contains 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, cement, and other masonry products.
— Arsenic and chromium from chemically-treated lumber.

work. To reduce your exposure to these chemicals:
— Work in a well-ventilated area.
— Work with approved safety equipment, such as dust masks that are specially
designed to lter out microscopic particles.
— Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth or eyes or to lie on the skin may
promote absorption of harmful chemicals.

󰌥SAFETY INFORMATION
Electrical Safety
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodied plugs and
matching outlets will reduce risk of electric shock.
•Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
• Donotexposepowertoolstorainorwetconditions.Water entering a power tool will
increase the risk of electric shock.
• Donotabusethecord.Neverusethecordforcarrying,pullingorunpluggingthe
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
• Whenoperatingapowertooloutdoors,useanextensioncordsuitableforoutdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• Ifoperatingapowertoolsinadamplocationisunavoidable,useaground-fault
circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric
shock.
Personal Safety
• Stayalert,watchwhatyouaredoingandusecommonsensewhenoperatinga
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools
mayresultinseriouspersonalinjury.
• Usepersonalprotectiveequipment.Alwaysweareyeprotection.Protective equip-
ment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriateconditionswillreducepersonalinjuries.
• Preventunintentionalstarting.Ensurethattheswitchisintheoff-positionbefore
