2 Safety instructions2.1 General Power Tool Safety Warningsa) WARNING

Read all safety warnings and instructions. Failureto follow the warnings and instructions may resultin electric shock, fire and/or serious injury. Save allwarnings and instructions for future reference.The term “power tool” in the warnings refers toyour mains-operated (corded) power tool or battery-operated (cordless) power tool.

2.1.1 Work area safetya) Keepwork area clean and well lit. Cluttered or dark

areas invite accidents.b) Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammableliquids, gases or dust. Power tools create sparkswhich may ignite the dust or fumes.

c) Keep children and bystanders away while operat-ing a power tool. Distractions can cause you to losecontrol.

2.1.2 Electrical safetya) Power tool plugs must match the outlet. Never

modify the plug in anyway. Do not use any adapterplugs with earthed (grounded) power tools. Un-modified plugs and matching outlets will reduce riskof electric shock.

b) Avoid body contact with earthed or groundedsurfaces such as pipes, radiators, ranges andrefrigerators. There is an increased risk of electricshock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet condi-tions. Water entering a power tool will increase therisk of electric shock.

d) Do not abuse the cord. Never use the cord forcarrying, pulling or unplugging the power tool.Keep cord away from heat, oil, sharp edges ormoving parts.Damaged or entangled cords increasethe risk of electric shock.

e) When operating a power tool outdoors, use anextension cord suitable for outdoor use. Use ofa cord suitable for outdoor use reduces the risk ofelectric shock.

f) If operating a power tool in a damp location isunavoidable, use a residual current device (RCD)protected supply. Use of an RCD reduces the riskof electric shock.

2.1.3 Personal safetya) Stay alert, watch what you are doing and use

common sense when operating a power tool. Donot use a power tool while you are tired or underthe influence of drugs, alcohol or medication. Amoment of inattention while operating power toolsmay result in serious personal injury.

b) Use personal protective equipment. Always weareye protection. Protective equipment such as dustmask, non-skid safety shoes, hard hat, or hearingprotection used for appropriate conditionswill reducepersonal injuries.

c) Prevent unintentional starting. Ensure the switchis in the off‐position before connecting to powersource and/or battery pack, picking up or carryingthe tool. Carrying power tools with your finger on theswitch or energising power tools that have the switchon invites accidents.

d) Remove any adjusting key or wrench before turn-ing the power tool on. A wrench or a key left at-tached to a rotating part of the power tool may resultin personal injury.

e) Do not overreach. Keep proper footing and bal-ance at all times. This enables better control of thepower tool in unexpected situations.

f) Dress properly. Do not wear loose clothing orjewellery. Keep your hair, clothing and glovesaway from moving parts. Loose clothes, jewelleryor long hair can be caught in moving parts.

g) If devices are provided for the connection of dustextraction and collection facilities, ensure theseare connected and properly used. Use of dustcollection can reduce dust-related hazards.

2.1.4 Power tool use and carea) Do not force the power tool. Use the correct

power tool for your application. The correct powertool will do the job better and safer at the rate forwhich it was designed.

b) Do not use the power tool if the switch does notturn it on and off. Any power tool that cannot becontrolled with the switch is dangerous and must berepaired.

c) Disconnect the plug from the power sourceand/or the battery pack from the power toolbefore making any adjustments, changingaccessories, or storing power tools. Suchpreventive safety measures reduce the risk ofstarting the power tool accidentally.

d) Store idle power tools out of the reach of chil-dren and do not allow persons unfamiliar with thepower tool or these instructions to operate thepower tool. Power tools are dangerous in the handsof untrained users.

e) Maintain power tools. Check for misalignment orbinding of moving parts, breakage of parts andany other condition that may affect the powertool’s operation. If damaged, have the power toolrepaired before use.Many accidents are caused bypoorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly main-tained cutting tools with sharp cutting edges are lesslikely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc.in accordance with these instructions, taking intoaccount the working conditions and the work tobe performed. Use of the power tool for opera-tions different from those intended could result in ahazardous situation.

2.1.5 Servicea) Have your power tool servicedby a qualified repair

person using only identical replacement parts.This will ensure that the safety of the power tool ismaintained.

2.2 Hammer safety warningsa) Wear ear protectors. Exposure to noise can cause

hearing loss.b) Use auxiliary handles, if supplied with the tool.

Loss of control can cause personal injury.c) Hold power tool by insulated gripping surfaces,

when performing an operation where the cuttingaccessory may contact hidden wiring or its owncord. Cutting accessory contacting a "live" wire maymake exposed metal parts of the power tool "live"and could give the operator an electric shock.

2.3 Additional safety instructions2.3.1 Personal safetya) Modification of the machine or tampering with its

parts is not permissible.b) Store power tools, when not in use, in a secure

place. When not in use, power tools must bestored in a dry, high place or locked away out ofreach of children.

c) Improve the blood circulation in your fingers byrelaxing your hands and exercising your fingersduring breaks between working.

d) Always lead the supply cord and extension cordaway from the power tool to the rear while work-ing. This helps to avoid tripping over the cord whileworking.

e) The appliance is not intended for use by debili-tated persons who have received no special train-ing. Keep the appliance out of reach of children.

f) Dust from materials, such as paint containing lead,some wood species, concrete / masonry / stone con-taining silica, and minerals as well as metal, may be

harmful. Contact with or inhalation of the dust maycause allergic reactions and/or respiratory or otherdiseases to the operator or bystanders. Certain kindsof dust are classified as carcinogenic such as oak andbeech dust, especially in conjunction with additivesforwood conditioning (chromate, wood preservative).Material containing asbestos must only be treated byspecialists.Where the use of a dust-extraction de-vice is possible it shall be used. To achieve ahigh level of dust collection, use a suitable dustextractor. When indicated wear a respirator ap-propriate for the type of dust generated. Ensurethat the workplace is well ventilated. Follow na-tional requirements for the materials you want towork with.

2.3.2 Electrical safetya) Concealed electric cables or gas and water pipes

present a serious hazard if damaged while youare working. Accordingly, check the area in whichyou are working beforehand (e.g. using a metaldetector). External metal parts of the power tool ormachine may become live, for example, when anelectric cable is damaged accidentally.

b) Check the power tool’s supply cord at regularintervals and have it replaced by a qualified spe-cialist if found to be damaged. If the machine’ssupply cord is damaged it must be replaced witha specially-prepared and approved supply cordavailable from Hilti Customer Service. Check ex-tension cords at regular intervals and replacethem if found to be damaged. Do not touch thesupply cord or extension cord if it is damagedwhile working. Disconnect the mains plug fromthe power outlet. Damaged supply cords or exten-sion cords present a risk of electric shock.

c) Dirty or dusty power tools which have been usedfrequently for work on conductive materialsshould be checked at regular intervals at a HiltiService Center. Under unfavorable circumstances,dampness or dust adhering to the surface ofthe power tool, especially dust from conductivematerials, may present a risk of electric shock.

d) Hold power tool by insulated gripping surfaceswhen performing an operation where the fastenermay contact hidden wiring or its own cord. Fas-teners contacting a “live” wire may make exposedmetal parts of the power tool “live” and could givethe operator an electric shock.

e) Switch the power tool off and unplug the supplycord in the event of a power failure or interruptionin the electric supply. This will prevent accidentalrestarting when the electric power returns.

2.3.3 Work areaa) Ensure that the workplace is well ventilated. Ex-

posure to dust at a poorly ventilated workplace mayresult in damage to the health.

b) Keep the workplace tidy. Objects which couldcause injury should be removed from the work-

en
