󰌥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
equipment 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

unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
• Maintainpowertools.Checkformisalignmentorbindingofmovingparts,
breakage 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
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could
