Safety instructions

Read these safety instructions, these original instructions, the safety instructions provided with the battery pack and the operating instructions supplied with the battery pack/standard charger before using the device for the first time. Proceed accordingly. Keep the booklets for future reference or for future owners.
In addition to the notes in the operating instructions, you also need to take into consideration the general safety regulations and accident prevention guidelines applicable by law.

Hazard levels

• Indication of an imminent threat of danger that will lead to severe injuries or even death.

• Indication of a potentially dangerous situation that may lead to severe injuries or even death.

• Indication of a potentially dangerous situation that may lead to minor injuries.

ATTENTION

• Indication of a potentially dangerous situation that may lead to damage to property.

General safety instructions

• Danger of explosion. The device creates sparks that may ignite dust, gas or vapours. Do not operate the device in explosive atmospheres, such as in the presence of flammable liquids, gases or dusts.

• Danger of accident. Keep your work area clean and well-lit.
• Keep children and other persons out of the work area while you are using the device.
• Risk of electric shock. Protect the device from rain and moisture.
• Avoid switching the device on unintentionally. Make sure that the on/off switch is in the off position before connecting the battery pack, lifting or carrying the device.
• Injuries through an adjustment key left in a rotating part of the tool. Remove the adjusting key before switching the device on.
• Do not run but rather walk when working with the device. Do not walk backwards. Avoid an abnormal posture, keep a stable, safe footing and maintain your balance.
• Never use the device if the on/off switch on the handle does not switch on and off correctly.
• Do not overload the device.
• Keep the cutting tools sharp and clean. Sharp cutting tools are easier to control and do not block so easily.
• Switch the motor off, remove the battery pack and make sure that all moving parts have stopped moving:
• Before making any adjustments.
• Before leaving the device unattended.
• Before checking, cleaning or servicing the device.
• Before removing a blockage or cleaning the ejection chute.
• Before changing accessories.
• After hitting a foreign object. First check the device for damage and repair any damage before restarting the device.
• When the device starts to vibrate unusually. First check the device for damage and repair any damage before restarting the device.

• You must not operate the device when you are under the influence of medication or drugs which restrict your reactive capacity. Only work with the device when you are well rested and are in good health.
• Wear suitable personal protective equipment when working with the device. Protective equipment such as dust masks, non-slip shoes, safety helmet or hearing protection reduce the risk of injury.
• Wear especially safety glasses and hearing protection.
• Hearing protection can impair your ability to hear warning sounds, so pay attention to hazards in your vicinity and in the work area.
• Wear head protection when working in areas with a danger of falling objects.

• Wear long, heavy trousers, clothing with long arms and non-slip boots when working with the device. Do not work barefoot. Do not wear sandals or short trousers. Avoid wearing loose clothing or clothing with cords and straps.

• Risk of injury when loose fitting clothing, hair or jewellery is caught by moving parts of the device. Keep clothing and jewellery away from moving parts of the device. Tie long hair back.
• Use the device and accessories only according to these instructions and take the working conditions and the work to be performed into consideration to avoid dangerous situations.

Safe operation

• Severe injuries when objects are flung by the cutting blade or when the cutting tool becomes entangled in wires or cords. Inspect the work area thoroughly for objects such as stones, sticks, metal, wires, bones or toys and remove these before using the device.

• The device is not intended for use by children, persons with restricted physical, sensory or mental abilities or persons unfamiliar with these instructions.
• Use the device only in daylight or under good artificial lighting.
• Do not operate the device on wet grass or in the rain.
• Maintain a minimum distance of 15 m from persons and animals. Stop the device when any persons or animals enter this area.
• Keep the cutting head below the level of your hips.
• Never use the device with damaged or absent safety devices.
• Never use a metallic cutting string.
• Only operate the device outdoors.
• Keep your hands and feet away from the cutting area, especially when switching on the motor.
• Risk of injury because the blades continue rotating after the motor has been switched off.
• Danger of injury. The blade on the protective cover for shortening the cutting string is very sharp and you must avoid touching this, especially when cleaning the device.
• Make sure that the ventilation openings are free of deposits.
• Check the device for damage before each use and after any impacts. Damaged parts, e.g. a switch, must be repaired or replaced by the authorised Customer Service department.
• Ensure that the drive head attachment is correctly fitted and fastened.
• Ensure that all protective devices, deflectors and handles are correctly fitted and securely fastened.
• Check that the string cutter is correctly positioned and secured each time before use.
• Use only replacement strings from the original manufacturer. Do not use any other cutting attachment.
• Danger of injury. Do not make any modifications to the device.

Note

• Regulations may restrict the use of this device in some regions. Seek advice from your local authorities.

Safe servicing and care

• After pushing out a new string, bring the device into the normal operating position before switching it on.
• Ensure that the device is in a safe condition by regularly checking that all bolts, nuts and screws are screwed tight.
• Check that the moving parts function correctly and are not blocked, and that no parts are broken or damaged. Have a damaged device repaired before using it.
• Switch the motor off, remove the battery pack and make sure that all moving parts have stopped moving:
• Before cleaning or servicing the device.
• Before changing accessories.

• Only use accessories and spare parts which are approved by the manufacturer. Only original accessories and original spare parts ensure that the appliance will run fault-free and safely.

ATTENTION

• Clean the product with a soft, dry cloth each time after use.

Note

• Service and maintenance work may only be performed by suitably qualified and specially trained personnel. We recommend sending the product to an authorised service centre for repair.
• You may only perform the adjustments and repairs described in these operating instructions. Contact your authorised Customer Service department for other repairs.
• Have damaged or illegible warning signs on the device replaced by the authorised Customer Service department.

Safe transport and storage

• Switch the device off, allow it to cool down and remove the battery pack before storage or transportation.

• Risk of injury and damage to the device. Secure the device against movement or falling down during transport.

ATTENTION

• Remove all foreign bodies from the device before storage or transportation.
• Store the device in a dry, well ventilated location out of the reach of children. Keep the device away from corrosive substances such as garden chemicals.
• Do not store the device outdoors.

Residual risks

• Certain residual risks remain present, even when the device is operated in the prescribed manner. The following dangers can be present when using the device:
• Vibration can cause injuries. Use the correct tools for the job, use the handles provided and restrict the working time and hazard exposure time.
• Noise can cause hearing injuries. Wear hearing protection and limit the duration of exposure.
• Injuries due to flung objects.

Risk reduction

• Using the device for longer periods can cause poor circulation in the hands due to vibrations. A general period of use cannot be set, because this depends on several influencing factors:
• Personal tendency to suffer from poor circulation (frequently cold fingers, tingling sensation in the fingers)
• Low ambient temperature. Wear warm gloves to protect your hands.
• Holding the device too tightly hindering blood circulation.
• Continuous operation is more harmful than operation interrupted by work breaks.

You should see a doctor if using the device regularly and for lengthy periods of time, and in the event of repeated occurrences of symptoms such as tingling in the fingers or cold fingers.
