Safety

General power tool safety warnings

• Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
• Save all warnings and instructions for future reference.
• 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

• 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.

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 the switch is in the off-position before connecting to 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, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving pats.
• 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.

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 battery pack 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. 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, takinginto 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.

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.

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.

Personal safety

• Use the product and accessories only when they are in perfect working order.

• Never tamper with or modify the product or accessories in any way.

• Use auxillary grips supplied with the product. Loss of control can cause personal injury.

• Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking through. Parts breaking away could fal out and / or fall down causing injury to other persons.

• Always hold the tool with both hands on the grips provided. Keep the grips clean and dry.

• Hold the product by the insulated gripping surfaces when performing work in which the accessory tool might come into contact with concealed wiring. if the accessory tool comes into contact with a live wire, metal parts of the power tool can also become live, resulting in an electric shock.

• Do not touch rotating parts risk of injury!

• Wear eye protection, a hard hat and ear protection and suitable respiratory protection while the product is in use.

• Wear protective gloves when changing the accessory tool. Touching the accessory tool can result in Cuts and bums.

• Wear eye protection. Flying fragments can injure the body and eyes.

• Dust is produced by grinding. sanding, cutting and drilling can contain dangerous chemicals.

• Some examples are lead or lead-Daseo plans, Drick, COncrete other masonry products, natural stone
  and other products containing silicates; certain types or oOd, 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.

• Take frequent breaks and do physical exercises to improve the blood circulation in your fingers. High vibration during long periods of work can lead to disorders of the blood vessels and nervous system in the fingers, hands and wrists.

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 cause an explosion if you accidentally damage an electric cable or a gas or water pipe.

Power tool use and care
