General power tool safety instructions

Work area safety

• Keep the work area clean and well-lit. Dark or cluttered areas could lead to accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids or fumes, gases, or dust. Power tools could create sparks which may ignite the gases or fumes.
• Keep children and bystanders at a safe distance while operating the power tool.

Electrical safety

• Make sure that the power tool plugs match the outlet. Do not ever modify the plug in any way. Do not use adapter plugs with earthed power tools. Using unmodified plugs and matching outlets will reduce the risk of electric shock.
• Avoid body contact with earthed or grounded materials or objects, such as radiators, pipes, ranges, and refrigerators. There is a tremendous risk of electric shock if the operator’s body is earthed or grounded.
• Do not expose power tools to rain or any other wet conditions. Water entering a power tool could increase the risk of electric shock.
• Do not abuse the power cord. Never use the cord for carrying, pulling, or unplugging the electric tool. Keep the cord at a safe distance from heat, oil, sharp edges, and any moving parts. Damaged or entangled cords will increase the risk of electric shock.
• When operating an electric power tool outdoors, use an extension cable that has the appropriate specifications for outdoor use. The use of an extension cable suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location cannot be avoided, use a residual current device (RCD) protected supply. The 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 the power tool. Do not use the power tool if you are feeling tired or are under the influence of alcohol, drugs, or medication. A moment of inattention while operating the power tool may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, or hearing protection, non-skid safety shoes, or protective helmets, used in appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the power switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the power tool. Carrying power tools with your finger on the power switch or connecting power tools that have the switch in the on position to a power source can lead to accidents.
• Remove any adjusting keys or wrenches before turning on the power tool. An adjusting key or a wrench left attached to a rotating part of the power tool may result in personal injury.
• Do not stretch out your arms too far when operating the power tool. Keep balance and proper footing at all times. This helps the operator have better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from any moving parts. Loose clothes, jewelry, and/or long hair can be caught in moving parts.

Power tool use and care

• Do not force the power tool. Use the correct power tool for each application. The correct power tool will always do the job better and safer when used as intended.
• Do not use the power tool if the switch does not turn activate or deactivate it. Any power tool that cannot be controlled with the switch is extremely dangerous and must be repaired.
• Disconnect the main plug from the power source and/or the battery pack from the power tool before changing accessories, making any adjustments, or storing the power tool. Such preventive safety measures will reduce the risk of starting the power tool accidentally.
• When the power tool is not in use, store it out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to use and operate the power tool. Power tools are extremely dangerous in the hands of untrained users.
• Maintain the power tool. Check for misalignment or binding of moving parts, breakage of parts, leakage, and any other issue that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents and injuries are caused by poorly maintained power tools.
• Keep the cutting parts of the power tool sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are more precise and easier to control.
• Always use the power tool, accessories tool bits, etc. under the instructions of this instruction manual, taking into account the working conditions and the work that is to be performed. Use of the power tool for applications different from those intended could result in personal injury or cause damage to the power tool.
• Keep the handles and any grasping surfaces of the power tool dry, clean, and free of oil and grease. Slippery handles and grasping surfaces do not allow for the safe handling of the tool in unexpected circumstances.

Battery tool use and care

• Recharge the batteries only with the charger specified by the manufacturer. A charger that is used to charge unsuitable batteries can create a risk of fire.
• Use the power tool only with the specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• When the 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 the eyes, seek medical help immediately. Liquid ejected from the battery may cause irritation or burns.

Service

• Have the power tool serviced by qualified service personnel, using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Never attempt to repair damaged battery packs on your own. Service of battery packs should only be performed by the manufacturer or authorized service technicians.

Safety instructions specifically for cordless chain saws

• When the chainsaw is in operation, keep a certain distance between your body and the chainsaw. Before starting the chain saw, make sure that the chain is not in contact with anything. During the operation of the chainsaw, even the slightest distraction of the operator may cause clothing or body parts to be caught in the chain.
• Always hold the rear handle of the chain saw with your right hand and the front handle of the chain saw with your left hand. Doing the opposite will increase the risk of personal injury. Therefore, never grasp the rear handle with your left hand and grasp the front handle with your right hand.
• Since the chain may touch hidden wires, when operating the power tool only holds the insulated handle. When the chain comes into contact with a ”live” wire, the exposed metal parts of the tools may also become ”live” and lead to the operator getting electrocuted.
• Wear protective glasses and hearing protection. It is recommended to also wear protective equipment to protect the head, hands, legs, and feet. Protective clothing will reduce the risk of personal injury caused by flying debris or accidentally touching the chain.
• Do not operate the chainsaw on a tree. Operating the chain saw on a tree may cause personal injury.
• Make sure to stand firm and on a fixed, safe, and level surface before operating the chain saw. Slippery or unstable surfaces such as ladders may cause the operator to lose balance or lose control of the chain saw.
• When cutting a branch under tension, beware of kickback. When the tension on the wood fiber is released, the elastic force on the branch may impact the operator, or the chain saw may cause it to lose control.
• When cutting shrubs and saplings, be especially careful because slender materials may jam the chain and lead to injury.
• Before carrying the chain saw, turn it off and hold the front handle firmly. When transporting or storing the chain saw, be sure to close the guide cover. Properly operating the chain saw will reduce the possibility of accidental contact with a running chain.
• Lubricate, tension the chain, and replace accessories according to the instructions. Improperly tensioning or lubricating the chain may cause the chain to break or increase the possibility of kickback.
• Keep the handle dry, clean, and free of oil and grease. Greasy handles are prone to slippage.
• Only use the chain saw for cutting wood. Do not use the chain saw for purposes other than the ones intended.
• For example: Do not use the chain saw to cut plastic, stone, or non-wood building materials. The use of the chain saw for operations other than the intended ones will result in tool damage or physical injury.

Kickback – Causes and preventive measures

• If the head of the guide bar touches an object and the chain stops suddenly, kickback may occur.
• In some cases when the head of the guide bar touches an object, a sudden reaction force will be formed, which may cause the guide bar to bounce up and rush towards the operator, causing injury.
• Squeezing the chain along the upper part of the guide bar may quickly push the guide bar back toward the operator. Any of these reaction forces may cause the operator to lose control of the chain saw, resulting in injury.
• Do not rely solely on the safety equipment installed on the chainsaw.
• As a chain saw operator, you should take a variety of measures to prevent accidents or personal injury during cutting operations.
• Improper operation of the chain saw incorrect operation steps, or operating conditions will cause rebound. Observe the precautions described below:
• Keep a firm grip and hold the chain saw handle with both thumbs and the rest of your fingers. Adjust the position of the body and arms to prevent rebound forces. If the correct precautions are followed, the operator will be able to better control the tool, thus minimizing the risk of injury in case kickback occurs.
• Do not extend the tool too far and do not hold the chain saw above your shoulders during operation. This will help to prevent the head of the guide bar from touching the object and ensure better control of the tool in unexpected situations.
• Use only replacement guides and chains specified by the manufacturer. Using inappropriate replacement guide bars and chains may cause the chain to break and/or the guide bar to kick back.
•  Follow the manufacturer’s polishing and maintenance instructions to maintain the chain. Reducing the depth and height will cause frequent kickbacks.
