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-opera/eel (cordecl) power tool or battery-operated (cordless) power tool.

1)    Work area safety

A Keep work area clean and well
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 well away while using power tools.
Distractions can cause you to lose control.

2) Electrical safety

a) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, cookers and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
b) Do not expose power tools to rain or wet environments. Water entering a power tool will increase the risk of electrical shock.

3) Personal safety

a) Stay alert, check what you are doing and use common sense when using a power tool. Do not use the power tool when you are tired or under the influence of drugs, alcohol or medicines. A moment of inattention while operating a power tool 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. Make sure the appliance is turned off before inserting the battery pack, picking up or carrying the power tool. Carrying power tools with your finger on the switch or mounting the battery with the switch in “ON” position 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 machine may result in personal injury.

2.2 SPECIFIC SAFETY REGULATIONS FOR HEDGE TRIMMERS

• During work operations, always hold the machine firmly with both hands. Operating it with only one hand can cause loss of control and serious personal injury
• Keep all parts of the body away from the blade. Do not remove cut material or hold material to be cut when blades are moving. Blades continue to move after the switch is turned off. A moment of inattention while operating the hedge trimmer may result in serious personal injury.
• Carry the hedge trimmer by the handle with the blade stopped and taking care not to operate any power switch. Proper carrying of the hedge trimmer will decrease the risk of inadvertent starting and resultant personal injury from the blades.
• Hold the power tool by insulated gripping surfaces only, because the blade may come in contact with hidden wiring. Contact between cutter blades and a “live” wire may cause exposed metal parts of the tool to become “live” and give the operator an electrical shock.
• When transporting or storing the hedge trimmer, always fit the blade cover. Proper handling of the hedge trimmer will decrease the risk of personal injury from the blades.
• Do not use the hedge trimmer in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.

If something breaks or an accident occurs during work, turn off the motor immediately and move the machine away to prevent further damage; if an accident occurs with injuries or third parties are injured, carry out the first aid measures most suitable for the situation immediately and contact the medical authorities for any necessary health care. Carefully remove any debris which could cause damage or injury to persons or animals if ignored.

Prolonged exposure to vibrations can cause injuries and neurovascular disorders (also called “Raynaud’s syndrome” or “white finger”), especially to people suffering from circulation disorders. The symptoms can regard the hands, wrists and fingers and are shown through loss of sensitivity, torpor, itching, pain and discolouring of or structural changes to the skin. These effects can be worsened by low ambient temperatures and/or by gripping the hand grips excessively tightly. If the symptoms occur, the length of time the machine is used must be reduced and a doctor consulted.

2.3 ENVIRONMENTAL PROTECTION

• Scrupulously comply with local regulations for the disposal of packaging, deteriorated parts or any elements with a strong environmental impact; this waste must not be disposed of with regular waste, but must be separated and taken to collection centres, which will recycle the materials.
• Scrupulously comply with local regulations for the disposal of waste materials
• When the machine is withdrawn from service, do not dispose of it in the environment, but take it to a waste disposal facility in accordance with the local regulations in force.

Do not throw electrical equipment away with domestic waste. According to the European Directive 2012/19/EU on electrical and electronic equipment waste and its implementation in compliance with national standards, old electrical equipment must be collected separately, for eco-compatible recycling. If electrical equipment is disposed of in a landfill or in the ground, the harmful substances can reach the water table and enter the food chain, damaging your health and well-being. For further information on the disposal of this product, contact your dealer or a domestic waste collection service.

At the end of their working life, dispose of batteries paying due attention to the environment. Batteries contain material classified as hazardous for you and the environment. They must be removed and disposed of separately at a facility that accepts lithium-ion batteries.

Separate waste collection of the products and packaging used allows the materials to be recycled and reused. Reuse of recycled materials help to prevent environmental pollution and reduces the demand for raw materials.
