3 SAFETY INSTRUCTIONS
3.1 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.
3.1.1 Work area safety
- Keep work area clean and well lit. Cluttered or dark areas invite accidents.
- 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.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
3.1.2 Electrical safety
■ 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.
- 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.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- 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.
■ 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.
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.
3.1.3 Personal safety
■ 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.
■ 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.
■ 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.
■ 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.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
■ 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.
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.
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.
3.1.4 Power tool use and care
- 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.
- 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.
■ 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.
■ 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. - 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.
- Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
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. - 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.
3.1.5 Battery tool use and care
■ 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.
■ Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
- 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.
■ 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. - 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.
- Do not expose a battery pack to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.
■ Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the operating instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.
3.1.6 Service
■ Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
■ Never service damaged battery packs.
Service of battery packs should only be performed by the manufacturer or authorized service providers.
3.2 Lawnmower safety warnings
Do not use the lawnmower in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
■ Thoroughly inspect the area for wildlife where the lawnmower is to be used. Wildlife may be injured by the lawnmower during operation.
■ Thoroughly inspect the area where the lawnmower is to be used and remove all stones, sticks, wires, bones, and other foreign objects. Thrown objects can cause personal injury.
Before using the lawnmower, always visually inspect to see that the blade and the blade assembly are not worn or damaged. Worn or damaged parts increase the risk of injury.
- Check the grass catcher frequently for wear or deterioration. A worn or damaged grass catcher may increase the risk of personal injury.
- Keep guards in place. Guards must be in working order and be properly mounted. A guard that is loose, damaged, or is not functioning correctly may result in personal injury.
- Keep all cooling air inlets clear of debris. Blocked air inlets and debris may result in overheating or risk of fire.
■ While operating the lawnmower, always wear non-slip and protective footwear. Do not operate the lawnmower when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact with the moving blade.
■ While operating the lawnmower, always wear long trousers. Exposed skin increases the likelihood of injury from thrown objects.
- Do not operate the lawnmower in wet grass. Walk, never run. This reduces the risk of slipping and falling which may result in personal injury.
- Do not operate the lawnmower on excessively steep slopes. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
- When working on slopes, always be sure of your footing, always work across the face of slopes, never up or down and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
■ Use extreme caution when reversing or pulling the lawnmower towards you. Always be aware of your surroundings. This reduces the risk of tripping during operation.
- Do not touch blades and other hazardous moving parts while they are still in motion. This reduces the risk of injury from moving parts.
- When clearing jammed material or cleaning the lawnmower, make sure all power switches are off and the battery pack is disconnected. Unexpected operation of the
lawnmower may result in serious personal injury.
■ Always allow the product to cool down before storing.
■ Empty the grassbox before storing.
- When adjusting the machine, make sure not to pinch your fingers between the moving blades and fixed parts of the machine.
3.3 Vibration load
Vibration total values and noise emission values
The declared vibration total values and noise emission values have been measured according to a standardised test method and can be used to compare one power tool with another.
The declared vibration total values and noise emission values can also be used for an initial assessment of the exposure.
The vibration total values and noise emission values may differ from the given value during actual use of the power tool, depending on how the power tool is used.
Adhere the safety measures according to the safety chapter. Try to keep the vibration load as low as possible. Exemplary measures to reduce vibration are the wearing of gloves when using the tool and the limitation of working time. All parts of the operating cycle must be taken into account (e.g. times when the power tool is switched off and those in which it is switched on but runs without load).
Danger due to vibration
The actual magnitude of the vibration emissions during the use of the appliance may deviate from that stated by the manufacturer. Observe the following influencing factors before or during use:
Is the appliance being used as intended?
Is the material being cut or processed in the proper manner?
Is the appliance in a proper condition of use?
Is the cutting tool properly sharpened or is the correct cutting tool installed?
Are the handle grips and any optional vibration grips mounted, and are they firmly attached to the appliance?
■ Only operate the tool at the motor speed required for the respective work. Avoid using
the maximum speed in order to reduce noise and vibrations.
The noise and vibrations of the tool may increase due to improper use and maintenance. This leads to health damage. In this case, immediately switch off the tool and have it repaired by an authorised service workshop.
The degree of stress due to vibration depends on the work to be performed or on the use of the tool. Estimate the stress and plan appropriate work breaks. This considerably reduces stress due to vibration over the entire working time.
■ Extensive use of the tool exposes the operator to vibrations, which can lead to circulatory issues ("white fingers"). To avoid this risk, wear gloves and keep your hands warm. If any symptoms of "white fingers" occur, immediately consult a physician. These symptoms include: Numbness, loss of feeling, tingling, itching, pain, reduced muscular strength, changes in the colour or condition of the skin. Normally these conditions affect the fingers, hands or pulse. The risk increases at low temperatures.
Take long breaks during your working day so you can recover from the noise and the vibrations. Plan your work in such a way that the use of appliances that generate strong vibrations is spread over several days.
If you notice an unpleasant sensation or discoloration of the skin on your hands when using the tool, stop work immediately. Take sufficient work breaks. Without sufficient breaks, a hand/arm vibration syndrome can occur.
- Minimise your risk of being exposed to vibrations. Maintain the tool according to the instructions in the operating instructions.
If the tool is used frequently, contact your dealer to purchase anti-vibration accessories (e.g. handles).
- Avoid working with the tool at temperatures below 10 °C. Define how the vibration load can be limited in a work plan.
3.4 Noise pollution
A certain level of noise exposure from this appliance is inevitable. Carry out noisy work at approved and specified time periods. Observe rest periods as necessary and restrict the duration of the work to a minimum. For your personal protection and protection of persons in the vicinity, appropriate hearing protection must be worn.
3.5 Safety notes for rechargeable battery and charger
■ Remove the batteries from the appliance before charging.
- Do not use different battery types or new and used batteries together in the appliance.
- Install the batteries in the appliance with the correct polarity.
■ Remove the batteries from the appliance before putting it into storage for an extended period.

10 TRANSPORT
10.1 Transporting the appliance
IMPORTANT! Risk of damage to the mower mechanism. At the lowest cutting height, the mower mechanism can be damaged by driving over steps, edges or kerbs.
■ Set the cutting height to the highest level for transport.
- Stop the mower mechanism and wait until it has come to a standstill.
- Set the highest cutting height.
Transporting the appliance between two working areas
■ Move the appliance to the working area with the mower mechanism set to the highest cutting height.
■ Use the handlebar to carry the appliance.
Transporting the appliance in a vehicle
■ Remove the batteries.
■ Fold down the handlebar.
- Secure the appliance in the vehicle against falling over and slipping.
■ Protect the appliance against collisions with loose objects.
■ Do not place objects on the appliance.
10.2 Transporting the battery
Perform the following measures before transporting the appliance:
- Switch off the appliance.
- Remove the battery from the appliance.
- Pack the battery properly (see below).
NOTE The following transport instructions apply only to a battery with more than 100 Wh nominal energy.
The Li ion battery contained in the appliance is subject to the hazardous goods law, but can be transported under simplified conditions:
The battery can be transported on public roads by the private user without further conditions provided it is packaged for retail sale and the transport serves personal purposes.
■ Commercial users who carry out the transport in connection with their main activity (e.g. delivery from and to building sites, or demonstrations) can also take advantage of this simplification.
In both cases, it is essential to take the mandatory precautions mentioned above to prevent any leakage of the contents. In other cases, it is essential to comply with the regulations of the hazardous goods law! In the case of non-compliance, severe penalties can be imposed on the sender and possibly the transporter.
Additional notes on transport and shipment
■ Only transport or ship the Li ion battery in an undamaged condition!
■ Use only the original cardboard box or a suitable hazardous goods cardboard box for transporting the battery (not required for batteries with a nominal energy less than 100 Wh).
■ Apply adhesive tape over exposed battery contacts to avoid the risk of a short circuit.
- Secure the battery against shifting in the packaging to avoid damage to the battery.
■ Ensure the correct marking and documentation of the shipment for transport or shipping (e.g. by parcel service or freight forwarding).
- Check in advance that transport with the selected service provider is possible and indicate the shipment.
We recommend involving a hazardous goods specialist in preparation of the shipment. Also heed any further national regulations.
