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 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.
  

Safety instructions for all saws

Cutting procedures

• DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
  
• Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
  
• Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
  
• Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimise body exposure, blade binding, or loss of control.
  

• Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and could give the operator an electric shock.
  

• When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
  
• Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run off-centre, causing loss of control.
  
• Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.
  

Kickback causes and related warnings

• kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
  
• when the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
  
• if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.
  

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

• Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.
  
• When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
  
• When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted.
  
• Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
  
• Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
  
• Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
  
• Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
  

Guard function

• Check the guard for proper closing before each use. Do not operate the saw if the guard does not move freely and enclose the blade instantly. Never clamp or tie the guard so that the blade is exposed. If the saw is accidentally dropped, the guard may be bent. Check to make sure that the guard moves freely and does not touch the blade or any other part, in all angles and depths of cut.
  
• Check the operation and condition of the guard return spring. If the guard and the spring are not operating properly, they must be serviced before use. The guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
  
• Assure that the base plate of the saw will not shift while performing a “plunge cut”. Blade shifting sideways will cause binding and likely kick back.
  
• Always observe that the guard is covering the blade before placing the saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after the switch is released.
  

Additional safety instructions

Personal safety

• Never tamper with or modify the power tool or accessories in any way.
  
• Operate the power tool only together with the safety devices that belong to it.
  
• If you use the power tool without a dust extractor, always wear light respiratory protection when undertaking work that creates dust.
  
• Always hold the power tool firmly with both hands on the grips provided.
  
• Wear ear protectors. Exposure to noise can cause hearing loss.
  
• Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers during breaks between working.
  
• The power tool is not intended for use by debilitated persons who have received no special training.
  
• Do not switch the power tool on until it is at the workplace and has been brought to its working position.
  
• Remove the battery if a problem occurs with the power tool, whenever you change accessory tools or accessories and before storing or transporting the power tool.
  
• Do not work overhead with the power tool.
  
• Do not attempt to brake the power tool by applying lateral pressure to the saw blade.
  
• Before inserting the battery, check that the saw is switched off and that the switch-on interlock is engaged in the lock‒off position. In this way you avoid injuries due to unintentional starting of the power tool.
  
• The switch-on interlock must always be engaged in the lock‒off position whenever you change accessories or the battery, for transport and when you are going to stow the power tool away.
  
• While the power tool is running, do not touch the clamping flange or the clamping screw.
  
• Before you lay down the power tool, wait until the saw blade has come to a complete stop.
  
• Before changing the accessory tool, wait until the power tool has cooled down.
  
• Never actuate the drive spindle lock while the saw blade is rotating.
  
• Never direct the power tool toward persons.
  
• Always use a saw blade suitable for the material and the condition of the workpiece.
  
• Never install abrasive wheels of any kind whatsoever on this power tool.
  
• Bring the power tool into contact with the workpiece only when the power tool is switched on.
  
• Adapt forward pressure to the saw blade and the material being cut. In this way you prevent the saw blade from stalling and possibly causing kickback.
  
• Avoid overheating the tips of the saw blade teeth.
  
• The rated speed of the accessory tool must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can disintegrate and fly apart.
  
• Do not work in an environment heavily contaminated with dust.
  
• 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.
  
• You and all others in the work area must always wear dust masks appropriate to the requirements of the application.
  
• You and all others in the work area must wear suitable eye protection, hard hat, ear protection, protective gloves and safety footwear 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 classification in compliance with locally applicable dust protection regulations.
  
• Comply with national health and safety requirements.
  
• Use clamps or some other practical means to secure the workpiece and keep it in a stable position. Attempting to stabilize the workpiece by hand or with your body is inadequate and can result in loss of control. Do not have the workpiece held in position by a helper.
  
• Never cut into unknown materials and keep the line of cut above and below the workpiece free of obstacles. The power tool can kick back if the saw blade comes into contact with an obstructing object.
  
• Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories are secure.
  

• When sawing in combination with a dust extractor, avoid touching the dust hood or the suction hose. When a material that produces dust in large quantities is worked, there can be an elevated risk of electrostatic shock.
  
• Make sure that the path of the saw is free of obstructions such as nails, screws and other metal objects.
  
• Use only saw blades recommended by Hilti that comply with the EN 847-1 standard.
  

• When cutting plastic, make sure that the workpiece does not become too hot and melt.
  

Electrical safety

• Before beginning work, check the working area (e.g. using a detector) to ensure that no concealed electric cables or gas and water pipes are present. External metal parts of the power tool can become live, for example if you accidentally damage electric wiring. This causes an increased risk of electric shock.
  

Careful handling and use of batteries

• 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.
  
• Use only batteries that are in perfect working order.
  
• 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 (176 °F).
