Safety

General power tool safety warnings

Image alternative WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric 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.
  • 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 and 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 result in a hazardous situation.
  • Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
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.

  • The product is not intended for use by debilitated persons who have received no special training. Keep the product out of reach of children.
  • Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone and other products containing silicates; certain types of wood, such as oak, beech and chemically treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and bystanders by means of the hazard classification of the materials to be worked. Implement the necessary measures to restrict exposure to a safe level, for example by the use of a dust collection system or by the wearing of suitable respiratory protection. The general measures for reducing exposure include:
  • working in an area that is well ventilated,
  • avoidance of prolonged contact with dust,
  • directing dust away from the face and body,
  • wearing protective clothing and washing exposed areas of the skin with water and soap.
  • The user and the other persons in the vicinity must wear eye protection, a hard hat, ear protection and breathing protection while the product is in use.
  • Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed accessories are secure.
  • Keep the air vents clear at all times. Risk of burn injuries due to blocked air vents!
  • Switch the product on only after you have brought it to the working position.
  • Wait until the product stops completely before you lay it down.
  • Do not attach a belt hook to this product.
  • Do not touch the metal head while the product is running because the head is hot.
  • Do not touch the hot cut area after cutting the material.
  • The saw blade or other metal parts can be hot or have sharp edges. Wear protective gloves when changing the saw blade, cleaning the chip collection bag, and cleaning the vents.
  • Do not hold the workpiece by hand, but use a vise or similar to prevent it from moving during cutting. If the workpiece moves or vibrates, the operation becomes unstable and cannot be controlled. Stop the operation immediately and secure the workpiece correctly, otherwise the blade will be damaged and serious injury can result.
  • Secure the workpiece to prevent the off-cut from falling and causing injury.
  • Metal chips and sparks from the cutting operation can damage the surroundings or cause a fire. Hot metal chips can melt the material of the chip collection bag. Do not operate the product near flammable or fragile items.
  • When working at height, it is recommended to install the chip collection bag. Hot chips can fly out and fall, burning the operators and bystanders.
  • Do not use a damaged chip collection bag. Fragments of the saw blade or sawdust could fall out of the chip collection bag and cause injuries.
  • When working at height, make sure there is no-one below. Off-cuts, material or products dropped could cause an accident.
  • Make sure no abnormal sounds or vibrations occur during operation. Operation when abnormal sounds or vibrations are perceptible can damage the blade, resulting in serious injury.
  • Metal chips are sharp and can cause injuries. Wear snug-fitting clothing to prevent chips from getting inside gloves, shoes, or elsewhere.
Kickback - causes and safety instructions
  • Kickback is the sudden reaction occurring when the saw blade snags, jams or is out of alignment, causing uncontrolled movement of the power tool away from the workpiece and toward the operator.
  • If the saw blade snags or jams in the kerf, it binds and motor force drives the power tool back toward the operator.
  • If the saw blade twists or is out of alignment in the kerf, the teeth at the trailing edge of the saw blade can snag in the surface of the workpiece, flicking the saw blade out of the kerf and driving the power tool back toward the operator.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions. It can be avoided by taking the proper precautions as described below.
  • Hold the power tool firmly, with your arms into a position where you can absorb the kickback forces. Always position yourself off to one side of the saw blade; never bring the blade into line with your body. In the event of a kickback, the power tool can jump backwards, but the operator can control the kickback forces by taking appropriate precautions.
  • If the saw blade jams and when you interrupt the operation, switch off the power tool and hold it with the saw blade in the material until the saw blade has come to a standstill. Never attempt to remove the power tool from the workpiece or pull it back while the saw blade is in motion, because kickback can occur. Investigate and take corrective action to eliminate the cause of the blade binding.
  • To restart a power tool that is stuck in the workpiece, center the saw blade in the kerf and make sure that no teeth are snagged in the workpiece. If the saw blade is jammed it can flick out of the kerf or cause kickback when the power tool is restarted.
  • Support large rebar to reduce the risk of kickback from a jammed saw blade. Large rebar can bend under its own weight.
  • Do not use a dulled or damaged saw blade. A saw blade with dulled or misaligned teeth causes increased friction, binding of the saw blade and kickback due to a narrow kerf.
Power tool use and care
  • Never use the product without the blade cover.
  • Tighten the insert tool and clamping flange securely. If the insert tool and clamping flange are not tightened securely, the insert tool can work loose from the arbor due to the braking effect of the motor as it slows down after being switched off.
  • Match the forward pressure of the product to the saw blade and the workpiece. In this way you prevent the saw blade from stalling and possibly causing kickback.
  • Start cutting only after the product has reached maximum speed. Touching the saw blade to the workpiece before starting the motor overloads and damages the saw blade, possibly resulting in serious injury.
  • Do not cut material that in size exceeds the cutting capacity of the product.
  • Make sure the saw blade is not deformed, chipped, cracked or worn out. Do not use a saw blade that exhibits damage or wear. Cutting under such conditions can cause further damage to the blade, chip collection bag with the adapter, and even result in serious injury.
  • Use only saw blades approved for the product that correspond to the specifications in the technical data. Using the saw blade for other applications can cause excessive wear, detachment of the blade, low cutting performance and abnormal generation of heat, resulting in damage to the saw blade and serious injury.
  • Do not use the product to cut material that is not specified in Intended Use.
Electrical safety
  • Before beginning work, check the working area for concealed electric cables or gas and water pipes. External metal parts of the product could give you an electric shock or an explosion could result if you accidentally damage an electric cable or a gas or water pipe.
  • Dirty or dusty products that have been used frequently for work on conductive materials should be checked at regular intervals by Hilti Service. Dust (especially dust from conductive materials) or dampness adhering to the surface of the power tool may, under unfavorable conditions, lead to electric shock.
Workplace
  • Slits cut in load-bearing walls of buildings or other structures may influence the statics of the structure, especially when steel reinforcing bars or load-bearing components are cut through. Consult the responsible structural engineer, architect or person in charge of the building project before starting work.

Hilti Li-ion batteries

Instructions for safety and useThis documentation uses the term battery to describe rechargeable Hilti Li-ion battery packs containing several Li-ion cells joined together. These batteries are to be used in Hilti power tools exclusively. Use only genuine Hilti batteries!
DescriptionHilti batteries have cell-management and cell-protection systems.
The batteries are composed of cells that contain lithium-ion storage materials capable of providing high specific energy density. Li-ion cells have a minimal memory effect, but they are very susceptible to external impact, deep discharge, and high temperatures.
The products approved for use with Hilti batteries can be found in your Hilti Store or at: www.hilti.group
Safety
  • Comply with the following safety instructions for the safe handling and use of Li-ion batteries. Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
  • Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely harmful to health!
  • Do not under any circumstances modify or tamper with batteries!
  • Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
  • Never use or charge a battery that has suffered an impact or been damaged in any other way. Check your batteries regularly for signs of damage.
  • Never use recycled or repaired batteries.
