risk of injury.
The rotating knife can cause injuries and ob-
jects can be thrown out. The area in front of
and to the right of the device is especially dan-
gerous.
On slopes, the device can topple over and
slide towards persons or run them over.
Make sure
– that nobody else besides the user is on the
mowing area.
– that people are never positioned in the direc-
tion of travel in front of the device.
– that nobody is positioned on the slope below
the device.
– that you have a complete overview of the
danger area at all times.
– that you keep your hands and feet away
from the rotating parts.

11
Use caution during operation
Danger of injury during motor start
The motor must not be started,
– When other persons are in close proximity.
Start the device only when your feet are at a
safe distance to the blade.
When the engine is started, do not tilt the
device.
Risk of injury when the motor is running
Switch off the engine and wait until the blade
stops
– when you drive on surfaces other than
grass.
– before you adjust the cutting height.
– before you remove, insert or replace a bat-
tery.
Switch off the engine, wait until the blade stops
and remove all batteries,
– before you tilt or transport the device.
– before you step away from the device, even
for just a short time.
– before you clean or check the device or be-
fore you carry out work on the device.
– before you unblock or unclog the discharge
area.
Prior to mowing
Personal protective measures
During mowing, always wear
safety shoes with good grip and
long trousers. Do not mow with
open sandals or while shoeless.
Wear safety gloves to protect
yourself against injuries and vi-
brations.
Noise is causing health prob-
lems. Use personal ear protec-
tion to avoid hearing damage.
Wear safety glasses and
headgear.
Ask your specialised dealer about suitable pro-
tective equipment.
Preparing the mowing area
Prior to mowing, carefully check the perimeter
of the lawn. Remove rocks, pieces of wood,
bones, wires, and other objects that could be
picked up and thrown out by the device.
Remove live cables from the mowing area.
These can be damaged during mowing and
cause an electric shock or short circuit.

12
Use caution when mowing
Risk of injury
Risk of injury caused by ejected objects. Never
mow when persons, children, pets or material
assets are in the danger area.
Keep your hands and feet away from the rotat-
ing parts. Keep a distance to the ejection area
while working with the device.
Make sure that help can be provided in case of
an emergency.
Only mow during daylight or with adequate arti-
ficial lighting. Never mow in the event of uncer-
tain weather conditions and risk of lightning.
Be especially carefully when mowing on soft
ground, nearby landfills, ditches, dikes and wa-
ter edges.
Fig.2:
Avoid mowing damp grass, there is a sliding
risk!
Be extremely cautious when turning the device
round or pulling it toward you and when mov-
ing in reverse.
Always walk slowly!
Never lift or carry the device when the engine
is running.
Pay attention to traffic when working close to
roads.
Vibrations
When the device is used over a longer period
of time, vibrations can cause disturbances in
the blood supply of the hands. A generally ac-
cepted usage time cannot be determined.
– Use gloves.
– Take breaks on time.
Have an authorised service centre check the
device
– when the blade has hit an object.
– if the device starts to vibrate unusually
severely.
Mowing surfaces with fire hazard
– Carry a sufficient amount of suitable extin-
guishing media.
– Observe the mowed area even after mowing
to make sure that no fire breaks out.
To prevent a fire hazard, always keep the fol-
lowing components free of dirt, grass, hay,
leaking oil, grease, etc.:
– Engine
Driving on slopes
Fig.3:
Risk of injury during mowing on slopes due to
tipping over or sliding.
– Mow on steep terrain only when safe opera-
tion can be guaranteed.
– Do not mow excessively steep slopes.
– Take suitable precautions on steep slopes,
e.g. by using step irons.
– Always mow crossways to the slope, never
upwards or downwards.
– Always make sure that you step safely, use
non-slip safety shoes.
– Be extremely cautious when changing the
direction.

13
– Mow only when the ground is dry and has a
good grip.
– Mow only when the steerable front wheel is
locked.
When facing downhill, the device can roll
away. Park the device on level ground only
and secure it against rolling away.
Use the backpack battery only on level ground,
never on a slope.
If the device tilts or slips
– If you attempt to stop a device that is tilting
or slipping, severe injuries can result. If tilt-
ing or sliding cannot be stopped in the be-
ginning without endangering anyone, do not
continue to try to stop the device.
– Remove leaking fluids (oil, fuel, battery acid)
from the device and the floor. Deposit of
contaminated soil environment friendly ac-
cording to the local regulation.
– Undetectable damage may have occurred to
the device. In case of malfunctions, there is
a risk of injury. Have an authorised service
centre check the device.
When work is completed
Prior to leaving the device, wait until the engine
stops and remove all batteries
– to prevent unauthorised use.
– to prevent accidental starting.
After switching it off, let the device cool down
for at least 20 minutes before you store it in a
dry, closed, sufficiently ventilated room.
Use caution during maintenance
and repair
Only carry out work as described in these op-
erating instructions. Have an authorised ser-
vice centre perform all other work.
Only use blades and spare parts approved by
“AS-Motor”. Unauthorized blades and spare
parts can cause severe injuries.
Prior to all maintenance work, wait until the en-
gine stops and remove all batteries.
We explicitly point out that, in accordance with
the Product Liability Act, we are not liable for
damages that were caused by our devices if
– worn or damaged parts were not repaired or
replaced on time.
– these damages were caused by improper
repair.

17
Information on mowing
Prior to mowing, check the device for com-
pleteness, proper function, and cleanliness. A
dirty air filter causes overheating of the engine
which can result in engine damage.
To keep the area well maintained, mow fre-
quently and keep the grass short.
Only mow with a sharp and undamaged blade.
Have the blade sharpened and balanced regu-
larly (by authorised service centre).
Do not mow when the grass is wet or when it is
raining. The turf may be damaged and there is
a danger of slipping!
Turn the device around only in already mown
sections. Do not leave the device unattended
while the engine is running.
To avoid blockage during the ejection of grass,
we recommend, for flat terrain, to proceed ac-
cording to the mowing patterns. Mulch is
shredded into much smaller pieces when you
mow the terrain once again in the opposite dir-
ection.
If the grass is extremely high, mow twice at dif-
ferent cutting height settings.
Recommendation for the selection
of the engine speed
Eco
Reduced engine speed for extended battery
life and lower emissions.
Use with lower power requirements or in-
creased service life of the working tool.
Turbo
High engine speed for high performance.
Use with higher power requirements.

18
Prior to starting
Warning
A damaged or defective battery may smoke
or catch on fire and cause life-threatening
injuries or major damage to property.
► Do not use or charge a damaged or de-
fective battery.
► Dispose of a damaged or defective bat-
tery immediately in accordance with local
regulations.
► Follow the instructions in the chapters
“Safe handling of the battery” and “Safe
handling of the charger“.
Notes on the use of the battery
We recommend using 2 batteries with the
same capacity and state of charge, fully
charged if possible.
Use batteries with 7.5 Ah or mor capacity.
When using only one battery or batteries with
less than 7.5 Ah capacity, 80 % of the engine
power is available.
Use the backpack battery only in combination
with 2 batteries.
Checking the battery’s charging
status
