English 4 Safety Precautions
6 0478-131-9838-C

► Wait until the blades are no longer turning.
■ Sparks may be produced if the turning blades
hit 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 blades hit a foreign object when working,
the blades may be damaged or the blade posi‐
tion may be changed.
►If the blades hit an object, switch the lawn
mower off and check the lawn mower and
blades.
■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.
►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 blades may
come into contact with the live wires and dam‐
age 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. The user may
come into contact with the rotating blades and
be seriously injured.
The slope inclinations refer to the weight of the
lawn mower with empty grass catcher box.
With increasing weight, the slope inclination
on which the lawn mower can be used may be
reduced.

AR L battery is used: do not mow on slopes
steeper than 20°.
►If a STIHL AP 100, 200 battery is used: do
not mow on slopes steeper than 12°.

ing. This may result in serious injury to people
and damage to property.

12 Operating the Lawn Mower
12.1 Holding and Guiding the Lawn
Mower
► Hold the handlebar with both hands so the
thumbs enclose the handlebar.
12.2 Setting the Cutting Height
Eight cutting heights can be set:

–65 mm = position 5
–75 mm = position 6
–90 mm = position 7
–100 mm = position 8
The positions are indicated on the lawn mower.
The cutting height is set individually at all wheels.
The setting must be the same for all wheels.
Setting the rear cutting height
► Pull lever (1) from the notch and moved to the
desired position.

ECO Mode
ECO mode is activated after the lawn mower is
switched on.
When ECO mode is activated, the lawn mower
detects the current working conditions and
adjusts the blade speed automatically.
This may extend the battery life.
Activating ECO mode
► Press button (1).
LED (2) illuminates.

push the lawn mower forwards slowly and in a
controlled manner.
12.6 Emptying the Grass Catcher
Box
The flow of air generated by the blade raises
level indicator (1). The flow of air stops when the
grass catcher box is full. If the flow of air is too
low, level indicator (2) returns to its resting state.
This is a prompt to empty the grass catcher box.
The functionality of the level indicator is restric‐
ted if the flow of air is impaired. External influen‐
ces such as wet, dense or high grass, low cutting
levels, contamination or the like can impair the
flow of air and the functionality of the level indica‐
tor.
► If the level indicator drops to its resting state:
empty the grass catcher box.

lowing instructions may cause electrical shock,
fire and/or serious injury. Keep all safety
instructions and instructions for the future.
23.2 Training
a)Read the instruction manual carefully.
Ensure that you are familiar with the controls
and the correct use of the machine;
b)Never allow children or other persons who
are not familiar with the instructions for use
to use the lawn mower. Local regulations
may specify a minimum age for users;
c)Never mow in the vicinity of other persons,
particularly children or animals;
d)Be aware that the person operating the
machine or the user is responsible for acci‐
dents involving third parties or their property.
23.3 Preparatory Measures
a)Always wear sturdy shoes and long trousers
when operating the machine. Never operate
the machine barefoot or in lightweight san‐
dals. Avoid wearing loose clothing or clothing
with hanging cords or belts.
b)Inspect the area on which the machine is to
be used and remove any objects that could
be taken in and thrown up by the machine.
c)Before using the machine, always visually
inspect the cutting blade, the retaining pins
and the entire cutting unit for wear or dam‐
age. To avoid imbalance, worn or damaged
cutting blades and retaining pins must be
replaced in pairs. Worn or damaged warning
signs must be replaced.
23.4 Handling

d)Operate the machine only at walking pace.
e)Only mow across and never up or down the
slope.
f)Be particularly careful when changing direc‐
tion on a slope.
g)Do not mow on excessively steep slopes.
h)Be particularly careful when turning the lawn
mower around or pulling it towards you.
i)Stop the cutting blade(s) when the machine
needs to be tilted for transportation over sur‐
faces other than grass and when moving the
lawn mower from and to the area to be
mown.
j)Never use the lawn mower with damaged
safety devices or protective grilles or without
attached safety devices, e.g. deflectors
and/or grass-catching units.
k)Exercise care when starting or pressing the
starting switch and observe the manufactur‐
er's instructions. Ensure that you keep your
feet far enough away from the cutting
blade(s).
l)The lawn mower must not be tilted when

m)Do not start the motor when you are standing
in front of the discharge chute.
n)Never put hands or feet on or underneath
rotating parts. Always keep away from the
discharge opening.
o)Never lift or carry a lawn mower with the
motor running.
p)Stop the motor and pull out the starting key.
Ensure that all moving parts have come to a
complete stop:
–whenever you leave the lawn mower;
–before remedying blockages, including
those in the discharge chute;
–before checking, cleaning or working on
the lawn mower;
–after hitting a foreign object. Inspect the

tightly fastened.
23.5 Maintenance and Storage
a)Ensure that all nuts, pins and bolts are tightly
fastened and that the machine is in a safe
working condition.
b)Check the grass-catching unit regularly for
wear or loss of functionality.
c)In the interests of safety, replace all worn or
damaged parts.
d)Be aware that on machines with more than
one cutting blade, the movement of one cut‐
ting blade can cause the other cutting blade
to turn.
e)Ensure when adjusting the machine that your
fingers do not become pinched between
moving cutting blades and stationary parts of
the machine.
f)Allow the motor to cool down before storing
the machine.
g)Note when maintaining the cutting blades
that the cutting blades can be moved even if
the power source is switched off.
h)In the interests of safety, replace all worn or
damaged parts. Only use genuine spare
parts and accessories.
