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.

  1. Work area safety

    • a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
    • b) 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.
    • c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
  2. Electrical safety

    • a) 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.
    • b) 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.
    • c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
    • d) 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.
    • e) 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.
    • f) 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.
  3. Personal safety

    • a) 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.
    • b) 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.
    • c) 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.
    • d) 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.
    • e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
    • f) 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.
    • g) 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.
    • h) 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.
  4. Power tool use and care

    • a) 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.

    • b) 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.

    • c) 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.

    • d) 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.

    • e) 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.

    • f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

    • g) 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.

    • h) 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.

    • a) 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.

    • b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

    • c) 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.

    • d) 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.

    • e) 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.
      f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.

    • g) 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.

Safety Warning for rechargeable chain saws
  1. Keep all parts of the body at arm’s length from the chainsaw while it is in operation. Before starting the chainsaw, make sure that the chain is not in contact with anything. Even a moment of distraction during chain saw operation may result in clothing or body being sucked into the chainsaw.

  2. Be sure to hold the rear handle of the chainsaw with your right hand and the front handle with your left. Holding a chainsaw upside down increases the risk of personal injury, so do not hold the back handle with your left hand and the front handle with your right.

  3. Because the chain may come into contact with hidden wires, only hold the insulated handle when operating the tool. When the chainsaw comes into contact with a live wire, the exposed metal part of the tool may also become live and cause an electric shock to the operator.

  4. Wear safety glasses and ear protectors. It is recommended that you wear a protective device to protect your head, hands, legs and feet. Wearing protective clothing will reduce personal injury from flying debris or accidental contact with a chainsaw.

  5. Do not operate a chainsaw in a tree. Operating a chainsaw in a tree can cause personal injury.

  6. Be sure to stand firmly and to stand on a fixed, safe and level surface before operating the chainsaw. Slippery or unstable surfaces such as ladders can cause the body to lose its balance or the chainsaw to lose control.

  7. When cutting a branch under tension, beware of a rebound. When the tension on the wood fibers is released, the elastic forces on the branches may strike the operator or the chain saw and cause it to lose control.

  8. Be especially careful when cutting through shrubs and young trees. Slender materials may trap the chain and strike themselves or cause self-imbalance.

  9. Close the chain saw and hold the front handle at arm’s length before carrying it. When transporting or storing chainsaws, always cover the guide plate. Proper operation of the chainsaw reduces the likelihood of accidental contact with the chain in motion.

  10. Lubricate, tensify chains and replace accessories according to instructions. Improper tensioning or lubrication of chains may result in chain rupture or increase the likelihood of rebound.

  11. Keep handles dry and clean, free of grease and grease. Greasy handles tend to slip and cause tools to slip out of control.

  12. Used only for cutting wood. Do not use chain saws for purposes other than
    design. For example, do not use chain saws to cut plastic stone or non-wood building materials. Use them for operations other than design purposes can lead to dangerous situations.

    • Causes of tool bounces and precautions taken by operators:

    • Rebound may occur if the head of the guide plate touches an object or the wood grips and squeezes the chain during cutting.

    • Sometimes, the head of the guide plate touches an object, creating a sudden reaction force that bounces the guide plate and charges the operator.
      Squeezing the chain along the top of the guide plate may push the guide plate back to the operator quickly.

    • Any of these counterforces can cause the chainsaw to go haywire and cause serious injury. Do not rely solely on safety equipment mounted on the chainsaw. As a chainsaw user, you should take a variety of measures to prevent accidental or personal injury during cutting.

    • Incorrect operation of the tool or incorrect operation steps or conditions will lead to a rebound, which can be avoided by following the following precautions:

    • With a firm grip, grip the chainsaw handle with both thumbs and the rest of your fingers, adjusting your body and arms to prevent rebound. The operator can control the recoil if the correct precautions are followed. Please be careful.

  • Do not extend the tool too far and do not cut above the shoulder. This helps prevent the guide head from touching the object and gives better control of the tool in unexpected situations.

  • Use only replacement guides and chains specified by the manufacturer Improper replacement guides and chains may cause chain breakage or rebound.

  • Maintain the chainsaw following the manufacturer’s polishing and maintenance instructions. Lowering the depth gauge will cause frequent bounces.
    Please keep this instruction manual.

  • Warning: Do not be too familiar with the product (experience gained from repeated use) to not strictly follow the relevant product safety rules. Improper use or failure to follow the safety rules in the instructions can result in serious personal injury.
