IMPORTANT SAFEGUARDS:

IMPORTANT: READ ALL INSTRUCTIONS BEFORE USE. RETAIN INSTRUCTIONS FOR FUTURE REFERENCE.

WARNING: Basic safety precautions should always be observed when using an electrical appliance to reduce the risk of fire, electrical shock or serious injury.

Do not use in rain or leave outdoors whilst raining.

Personal Safety:

• Only use the trimmer in the manner intended and for trimming grass as described in this manual.
• Keep out of reach of children and animals at all times.
• Only use in daylight or good artificial light.
• Always be sure of your footing on uneven ground, slopes or in slippery conditions.
• Do not over-reach or use on excessive steep slopes.
• Remove any stones, loose debris and other objects from the cutting area.
• Pay special attention to the hazards posed to bystanders by thrown or flyaway objects.
• Stay alert, watch what you are doing and use common sense when operating a power tool.
• Do not use power tools while you are tired or under the influence of drugs, alcohol or medication. This may result in serious personal injury.
  • Always be aware of your surroundings and stay alert for possible hazards.
• Use protective personal equipment such as safety glasses, non-skid safety shoes, sturdy gloves to reduce the risk of personal injury.
• Do not operate when barefoot or wearing open toed shoes. Always wear substantial footwear and long trousers.
• Dress appropriately. Do not wear loose

clothing or jewellery and keep hair, clothing and gloves away from moving parts.

• Avoid accidental starting. Ensure the switch is in the off position before picking up or carrying the trimmer.
• Do not run with the trimmer.
• When operating the trimmer ensure that both hands are correctly positioned on the handle.
• Do not operate the trimmer if it is incomplete or has unauthorised modifications.
• Keep all body parts, especially hands and feet, away from the blade at all times.
• Warning, the blade will continue to move after the motor is switched off.
• Ensure that the motor has fully stopped before cleaning, clearing a blockage, checking, or carrying out maintenance on the trimmer.
• Carry the grass trimmer by the handle with the blade stopped.
• The operator is responsible for accidents or hazards occurring to other people at their property.
• Never operate the trimmer with damaged guards or without the guards in place.

- Avoid body contact with earthed or grounded surfaces, such as pipes. There is an increased risk of electric shock if your body is earthed or grounded.

- Do not expose trimmers to rain or wet conditions.

- Do not handle the charger or the trimmer with wet hands.

- Before charging check the power supply and charger cables for signs of damage or ageing.

- Do not overload the trimmer. Forcing the trimmer to cut may damage the motor. For safety the trimmer will automatically cut out if the motor becomes overloaded. If this occurs, wait a few seconds for the cut out to reset and then use lighter cuts to trim the grass.

WARNING: Risk of electric shock. Pay attention to the position of garden cables.

WARNING: To reduce the risk of personal injury always wear eye protection. Personal protective equipment such as sturdy gloves and non-slip shoes are recommended.

Pay attention to the hazard posed to third parties from the increased working area of the trimmer.

Always take care when other people are around you. The trimmer may throw out stones and debris at high speed.

Take care not to overload the trimmer. Attempting to force the trimmer to cut may damage the motor. To prevent overloading cut long or difficult foliage in stages with several light cuts.

Take care not to grind the rotating parts against the ground as this will wear parts and cause damage to the trimmer.

Take care when trimming around objects such as stone or concrete as these can damage the trimmer blade and parts that attach the blade.

If the blade becomes worn or damaged it should be replaced with a new blade.
