ings. Never bridge the battery’s contacts with
metallic objects (short circuit). Do not open the battery. Replace worn or damaged labels. Fluid may leak from a damaged battery. If that liquid comes into contact with the skin or eyes, the skin or eyes may be irritated. Avoid contact with the liquid. If skin contact occurs: Wash affected areas
of skin with plenty of water and soap. In the event of contact with eyes: Rinse
eyes with plenty of water for at least 15 minutes and consult a doctor. A damaged or defective battery may smell unusual, emit smoke or burn. Persons may be seriously or fatally injured, and property may be damaged. If the battery smells unusual or emits smoke: do not use the battery and keep it away from combustible substances.

4.7 Working
WARNING
In certain situations, the user may no longer be able to concentrate on their work. This may
0478-131-9671-B

4 Safety Precautions
result in the user stumbling, falling and becom- ing seriously injured. Work calmly and carefully. If the light and visibility conditions are poor:
do not use the lawn mower. Operate the lawn mower alone. Watch out for obstacles. Do not tilt the lawn mower. Work standing on the ground and maintain
balance. If signs of fatigue occur: take a break. If mowing on a slope: mow across the
slope. Do not work on slopes with an inclination
greater than 25° (46.6%). The turning blade may cut the user. This may
result in serious injury to the user.
Do not touch a turning blade. If the blade is blocked by an object:
switch the lawn mower off and remove the battery. Only then remove the object.
If working without self-propulsion when mow- ing, self-propulsion may unintentionally be engaged and the lawn mower may start mov- ing. This may result in serious injury to people and damage to property. Only press the control bar for self-propul- sion if self-propulsion is to be engaged.
The lawn mower may cause vibrations when working. Wear protective gloves. Take breaks. If signs of a circulatory disturbance occur: consult a doctor.
If the blade hits a foreign object when working, the foreign object or parts of it may be dam- aged or thrown up at high velocity. This may result in injury to people and damage to prop- erty. Remove foreign objects from the work area.
When the control bar for mowing is released, the blade continues to turn for a short time. This may result in serious injury to people. Wait until the blade is no longer turning.
Sparks may be produced if the turning blade hits a hard object. Sparks may cause fires in highly flammable environments. This may result in serious or fatal injury to people and damage to property. Do not work in a highly flammable environ- ment.
If the lawn mower is stopped on a sloping sur- face, it may unintentionally roll away. This may result in injury to people and damage to prop- erty.

English
Only let go of the lawn mower if it is on a level surface and cannot roll away by itself.
If objects are attached to the handlebar, the additional weight may cause the lawn mower to tip over. This may result in injury to people and damage to property. Do not attach objects to the handlebar.
DANGER
If working near live wires, the blade may come into contact with the live wires and damage them. This may result in serious or fatal injury to the user. Do not work near live wires.
The user may be struck by lighting if working during a thunderstorm. This may result in seri- ous or fatal injury to the user. Do not work during thunderstorms.
The self-propulsion disengages in the event of overload when working on steep slopes. This causes the user to spontaneously have to apply a greater pushing force, which may cause the user to lose control of the lawn mower. The lawn mower may roll towards the user due to its own weight. Mow across the slope. Ensure a secure footing to maintain control of the lawn mower at all times.
4.8 Charging
WARNING
A damaged or defective charger may produce an unusual smell or emit smoke during the charging process. This may result in personal injuries and damage to property. Disconnect the plug from the wall outlet.
The charger can overheat and cause a fire if heat dissipation is inadequate. This can result in serious or fatal injuries and damage to prop- erty. Do not cover the charger.
4.9 Connecting to the power supply
Contact with live components may occur for the following reasons: ­ The connecting cable or the extension cord is
damaged. ­ The mains plug of the connecting cable or
extension cord is damaged. ­ The socket is not properly installed.
DANGER
Contact with live parts may result in electric shock. This may result in serious or fatal injury to the user.

Make sure your hands are dry before touch- ing the connecting cable, extension cord or mains plugs.
Plug the mains plug of the connecting cable or extension cord into a properly installed, shockproof socket with the correct fuse rat- ing.
Install the charger with a ground fault circuit interrupter (30 mA, 30 ms).
A damaged or unsuitable extension cable can result in electric shock. There is a risk of seri- ous or fatal injury. Use an extension cable with the correct cable cross-section, 21.5.

The extension cable warms up in operation. If that heat cannot escape, it may cause a fire. If using a cable reel: completely unroll the cable reel.
If wiring and pipes are laid in the wall, they may be damaged if the charger is mounted on the wall. Contact with wiring can result in elec- tric shock. This may result in serious injury to people and damage to property. Make sure there is no wiring or pipes in the wall at the proposed mounting site.
If the charger is not mounted on the wall as described in this User Manual, the charger or the battery may fall or the charger may over- heat. This may result in injury to people and damage to property. Mount the charger on a wall as described in this User Manual.

WARNING
Overvoltage can occur in the charger if the line voltage or frequency are incorrect during charging. The charger may be damaged. Make sure that the mains voltage and the mains frequency of the power supply match
