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

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.
• Yourriskfromtheseexposuresvaries,dependinguponhowoftenyoudothistypeof

— 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.

General Power Tool Safety Warnings
󰌥WARNING
Read all safety warnings and all instructions. Failure to follow all warnings and instructions
mayresultinelectricshock,reand/orseriousinjury.
Save all warnings and instructions for future reference
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Work Area Safety
• Keep work area clean and well lit. Cluttered and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust
or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.

󰌥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
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your nger on the switch or energizing power tools that have
the switch on invites accidents.
• Removeanyadjustingkeyorwrenchbeforeturningthepowertoolon.A wrench or
akeyleftattachedtoarotatingpartofthepowertoolmayresultinpersonalinjury.
• Donotoverreach.Keepproperfootingandbalanceatalltimes.This enables better
control of the power tool in unexpected situations.
• Dressproperly.Donotwearlooseclothingorjewelry.Keepyourhair,clothingand
gloves away from moving parts. Looseclothes,jewelryorlonghaircanbecaughtin

age of parts and any other condition that may affect the power tool’s operation.
If damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
• Keepcuttingtoolssharpandclean.Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control;
• Usethepowertool,accessories,toolbits,etc.inaccordancewiththeseinstruc-
