fore you carry out work on the device.
– before you unblock or unclog the discharge
area.
Risk of burns
Do not touch the engine or the silencer. These
parts become very hot during operation and
you can get burned. If a jumpy movement oc-
curs, the risk of additional injuries can result.
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.
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.

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 agent.
– If side inclination is too great, fuel may leak
from the carburetor or the tank. This poses a
fire hazard!
– Observe the mowed surface also after mov-
ing is completed to ensure that no fire will
start.
To avoid risk of fire, keep the following com-
ponents free of dirt, grass, hay, leaking oil,
grease, etc.:
– Engine
– Silencer (manifold, guard, clearances)
– Area around the fuel tank

Information on mowing
Prior to mowing, check your device for com-
pleteness, proper functioning, and cleanliness.
A dirty ventilation grid causes overheating of
the engine, this can damage the engine. A dirty
protective grid at the silencer poses a fire haz-
ard.
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.
Prior to starting
Fuel
As fuel, use unleaded petrol (see operating in-
structions of the engine manufacturer).
You can use E10 petrol. Do not store E10 pet-
rol longer than 30 days.
Tanking up
Danger!
Fuel is ignited by hot engine parts.
Prior to filling up, switch off the en-
gine and wait for at least 20minutes
until the engine has cooled down.
Observe the safety instructions re-
garding the fuel!
Filling up with fuel
1. For filling, use a canister with filler spout or
a funnel.
2. Open the canister carefully so that existing
excess pressure is slowly reduced.
3. Open the tank cap carefully so that existing
excess pressure is slowly reduced and no
fuel sprays out.
4. Fill the fuel tank.
5. Tightly close the tank cap again.
Checking the engine oil level
Attention! Prior to each use, check the engine
oil level (see operating instructions of the en-
gine manufacturer).
To ensure sufficient oil supply for the four
stroke engine and to avoid resulting engine
damage, the device may only be used on
slopes up to 20°.
Adjusting cutting height
Adjust the cutting height setting only when the
engine is switched off.
Set the cutting height so that the blade does
not touch the ground even in case of terrain
unevenness. If the cutting height is set too
high, objects can be ejected and the “clean cut
appearance” can be destroyed.
The rear wheel height setting determines the
coarse setting of the cutting height. The height
of the steerable front wheel determines the fine
setting of the cutting height.

15
Cutting height at the rear wheels
The rear wheels can be mounted in two differ-
ent levels.
1. Switch off the engine and wait until the
blade has come to a standstill.
2. Remove the wheel cap from the rear
wheel.

6. Tighten the rear wheel to a torque of
40+5Nm.
7. Put the wheel cap back on.
8. Carry out the same procedure at the other
rear wheel.
Notice: To increase speed, a pinion with
13teeth is available as accessory. If this pinion
is installed, the wheel bolt must be screwed in
the other bore holes(4)/(5).
