Safety

2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in   lectric shock, fire 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 or 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.

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. Unmodified 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 tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD 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 a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
▶ Prevent unintentional starting. Ensure 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 finger on the switch or energising 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 jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
▶ If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
▶ Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Power tool use and care
▶ Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
▶ Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
▶ Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
▶ Store idle power tools out of the reach of children and do not allow persons 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 and accessories. 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.
Battery tool use and care
▶ Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
▶ Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
▶ When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
▶ Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
▶ Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
▶ Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130° C (265 °F) may cause explosion.
▶ Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.
Service
▶ Have your power tool serviced by a qualified repair person using only identical replacement parts.  this will ensure that the safety of the power tool is maintained.
▶ Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.
2.2 Safety instructions for reciprocating saws
▶ Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a   live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
▶ Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
2.3 Additional safety instructions for saws
Personal safety
▶ Keep your hands away from the cutting area and the blade.
▶ Do not reach underneath the workpiece.
▶ Position yourself off to one side of the blade, never bring the blade into line with your body. The saw can jump backward toward you if kickback occurs.
▶ Never use the power tool without a fully functional hand guard.
▶ If the saw blade binds or when you interrupt work for any reason, switch off the saw and hold it motionless in the material until the saw blade comes to a complete stop. Never attempt to remove the saw from the workpiece or pull the saw back while the blade is in motion, as otherwise the saw could kick back.
▶ When restarting a saw in the workpiece, center the saw blade in the kerf and check that saw teeth are not in engagement with the workpiece.
▶ Use extra caution when sawing into walls or other blind areas. As it enters the material the blade might encounter a hidden obstruction, resulting in kickback.
▶ Always use a saw blade of appropriate length. The saw blade must project beyond the workpiece throughout the entire stroke.
▶ Do not use dull or damaged blades. These cause increased friction and present a high risk of the saw blade binding or kicking back.
▶ Secure the workpiece in a sturdy holder. Never hold  the workpiece with your hand or across your leg.
▶ Apply only moderate pressure and cut at an appropriate speed, especially when cutting large-diameter pipes. This will help to prevent the power tool overheating.
▶ Before cutting through pipes, make sure that they are empty of medium. Drain the pipes if necessary.
▶ When cutting through pipes, hold the power tool above the level of the pipe you are cutting through.
▶ The power tool is not protected against ingress of moisture. Liquid running out of a pipe can cause a short circuit in the power tool.
▶ Never cut into unknown materials and make sure the path of the saw is free of obstructions above and below the workpiece.
▶ The power tool can kick back if the saw blade comes into contact with an obstructing object. Comply with the manufacturer’s instructions for handling and storing saw blades.
2.4 Additional safety instructions
▶ Use the product only when it is in perfect working order.
▶ Never tamper with or modify the power tool in any way.
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes. External metal parts of the power tool can become live, presenting a risk of electric shock, if you accidentally damage an electric cable.
▶ Switch the product on only after bringing it to the working position.
▶ When working with the power tool, always guide it away from your body.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a risk of injury (cuts or burns).
▶ Always remove the battery when the power tool is not in use, before maintenance, before changing accessory tools and in preparation for and throughout transport.
▶ Engage the transport lock before storing or transporting the power tool.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a risk of injury (cuts or burns).
▶ The user and persons in the vicinity must wear suitable protective goggles, a hard hat, ear defenders, protective gloves and light respiratory protection while the power tool is in use.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use an industrial vacuum cleaner with an officially approved protection class in compliance with the locally applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of wood and concrete/masonry/stone containing quartz, minerals or metal can be harmful to health.
▶ Make sure that the workplace is well ventilated and, if necessary, wear a respirator appropriate for the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or respiratory or other diseases among operators or bystanders. Only specialists are permitted to handle material containing asbestos.
▶ When you use the Hilti retaining strap, make sure it is not damaged or frayed.
▶ Take breaks between working and do relaxation and finger exercises to improve the blood circulation in your fingers.
▶ Do not look directly into the light source (LEDs) of the power tool and do not aim the beam at other persons’ faces. Risk of dazzling or eye damage.
▶ Flying fragments can injure the body and eyes. Wear your personal protective equipment and always wear protective glasses and protective gloves.
▶ If work involves break-through, always secure the area on the side opposite where the work is carried out.
Electrical safety
▶ Hold the power tool by the insulated gripping surfaces when performing work in which the accessory  tool might come into contact with concealed wiring. If the accessory  ool comes into contact with a live wire, metal parts of the power tool can also become live, resulting in an electric shock.
2.5 Battery use and care
▶ Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height or show signs of damage. In this case, always contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. Put the battery in a place where it is clearly visible and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to cool down. If it is still too hot to touch after an hour, the battery is faulty. Contact Hilti Service.
