1.2 General safety warnings
1.2.1 General machine safety warnings
WARNING!
Read all safety warnings, instructions, illustrations and specifications provided with this machine. Failure to follow the warnings and instructions may result in electric shock, fire and / or serious injury.
Save all warnings and instructions for future reference.
The term “machine” in the warnings refers to your mains operated (corded) machine or battery operated (cordless) machine.

1. Work area safety
   a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
   b) Do not operate machines in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Machines create sparks which may ignite the dust or fumes.
   c) Keep children and bystanders away while operating a machine.
   Distractions can cause you to lose control.

2. Electrical safety
   a) Machine plugs must match the outlet. Never modify the plug in any way. Do not use any adaptor plugs with earthed (grounded) machines. Unmodified plugs and matching outlets will reduce risk of electric shock.
   b) 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.
   c) Do not expose machines to rain or wet conditions.
   Water entering a machine will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the machine. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a machine outdoors, use an extension cord suitable for outdoor use.
   Use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a machine 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. Personal safety
   a) Stay alert, watch what you are doing and use common sense when operating a machine. Do not use a machine while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating machines may result in serious personal injury.
   b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   c) 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 machine. Carrying machines with your finger on the switch or energising machines that have the switch on invites accidents.
   d) Remove any adjusting key or wrench before turning the machine on. A wrench or a key left attached to a rotating part of the machines may result in personal injury.
   e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the machine in unexpected situations.
   f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
   g) 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.
   h) Do not let familiarity gained from frequent use of machines allow you to become complacent and ignore machine safety principles. A careless action can cause severe injury within a fraction of a second.

4. Machine use and care
   a) Do not force the machine. Use the correct machine for your application. The correct machine will do the job better and safer at the rate for which it was designed.
   b) Do not use the machine if the switch does not turn it on and off. Any machine that cannot be controlled with the switch is dangerous and must be repaired.
   c) Disconnect the plug from the power source and / or the battery pack from the machine before making any adjustments, changing acces sories, or storing machines. Such preventive safety measures reduce the risk of starting the machine accidentally.
   d) Store idle machines out of the reach of children and do not allow persons unfamiliar with the machine or these instructions to operate the machine. Machines are dangerous in the hands of untrained users.
   e) Maintain machines. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the machine’s operation. If damaged, have the machine repaired before use. Many accidents are caused by poorly maintained machines.
   f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g) Use the machine, 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 machine for operations different from those intended could result in a hazardous situation.
   h) 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 machine in unexpected situations.

5. Battery tool use and care
   a) 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.
   b) Use machines only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   c) 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.
   d) 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.
   e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
   f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.
   g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

6. Service
   a) Have your machine serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the machine is maintained.
   b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorised service providers.

1.2.2 Lawnmower safety warnings

c) 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.
d) 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.
e) Check the grass catcher frequently for wear or deterioration. A worn or damaged grass catcher may increase the risk of personal injury.
f) 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.
g) Keep all cooling air inlets clear of debris. Blocked air inlets and debris may result in overheating or risk of fire.
h) 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.
i) While operating the lawnmower, always wear long trousers. Exposed skin increases the likelihood of injury from thrown objects.
j) 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.
k) 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.
l) 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.
m) 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.
n) Do not touch blades and other hazardous moving parts while they are still in motion. This reduces the risk of injury from moving parts.
o) 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.
p) When clearing jammed material or cleaning the lawnmower, make sure all power switches are off and remove the safety key. Unexpected operation of the lawnmower may result in serious personal injury. Stop the cutting means if the machine has to be tilted for transportation, when crossing surfaces other than grass and when transporting the machine to and from the area to be used.
Do not tilt the machine when switching on the motor, except if the machine has to be tilted for starting. In this case, do not tilt it more than absolutely necessary and lift only the part which is away from the operator. Stop the machine, remove the safety key and remove the battery, and make sure that all moving parts have come to a complete stop:
– After striking a foreign object, inspect the machine for damage and make repairs before restarting and operating the machine.
– If the machine starts to vibrate abnormally, immediately inspect for damage, replace or repair any damaged parts and check for and tighten any loose parts.

Maintain the mower at regular intervals.
This will extend the working life of the mower.
Only use spare parts recommended by GARDENA.
This is the only way to ensure safe use of the mower.
Be careful during adjustment of the machine to prevent entrapment of the fingers between moving cutting means and fixed parts of the machine.
Always allow the machine to cool down before storing.
When servicing the cutting means be aware that, even though the power source is switched off, the cutting means can still be moved.
We recommend to wear a hearing protection.

2. Turn the safety key (20) to position 0 and remove it, to prevent the batteries from discharging.

3.7 Hints to mow:
3.7.1 Hints to use the mower:
If grass residue is left in the discharge opening, pull the mower backwards about 1 m so that the grass residue can drop out downwards.
To produce a well-maintained lawn, we recommend to cut the lawn regularly once a week if possible. The lawn becomes denser if you cut it frequently.
After relatively long cutting intervals (holiday lawn), first of all cut in one direction with the highest cutting height and then cut in the crosswise direction with the required cutting height. This prevents a possible blockage of the blade by too much grass residue.
If possible, only cut the grass when it is dry. If the grass is damp, the cutting pattern will be uneven.

3.7.2 Cutting performance and battery charge:
The lawn area which can be cut on each battery charge depends on several factors such as moisture, grass density and cutting height. In order to ensure an optimal use of space, do not turn the mower on and off too frequently as this severely reduces the battery running time. The cutting performance for each battery charge can be ideally utilised by increasing the cutting height and frequent mowing.
The Eco mode reduces the motor speed to 3100 rpm for a maximum battery lifetime.

3.7.3 Lawn area per battery charge:
