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.:

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.
Frequent engagement and disengagement of
the clutch increases wear of the blade drive
belt and the blade brake. Especially in case of
high grass, clutch engagement leads to over-
load.
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.
For mowing, always turn the accelerator lever
to full throttle to achieve the best mowing per-
formance.

13
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).
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.
12 3
Fig.4:
The cutting height can be set in 5 levels of
10cm up to 110cm.
1. Switch off the engine and wait until the
blade comes to a standstill.

Cleaning the device
Depending on use, clean the device thor-
oughly, especially the bottom and the blade.
Grass cuttings and dirt that are stuck interfere
with the grass ejection and impair the cutting
quality. To sufficiently cool the engine, keep
the engine cover, ventilation grid and engine
clean.
Fire hazard! Take particular care that the com-
ponents at the silencer are clean.
For cleaning, use a hand brush. Remove stub-
born dirt with a wooden or plastic spatula.
Clean the outside housing parts with a cloth.
Do not clean the device with water spray or
high-pressure cleaner! Do not use any ag-
gressive cleaning agents.
General inspection
To make sure that the device can be operated
safely, check all nuts, bolts, screws, connec-
tions of fuel lines, air filters etc. regularly for
proper condition and firm seating. Check the
ignition wire and the spark plug connector for
damage.
Immediately replace damaged or worn parts,
especially covers, silencers or fuel tank
(authorised service centre).
Check all parts that that contain fluids for leaks
and proper condition. These can be: Fuel tank,
fuel valve, fuel lines, carburetor, engine, gears,
battery, hydraulic system.
In case of leaks, contact an authorised service
centre.
Chain lubrication
The chains to the right and to the left of the dif-
ferential lock must be lubricated at regular in-
tervals. We recommend using biodegradable
chain spray.
Transmission
The transmission is maintenance-free and
filled with oil that is supposed to last the entire
service life of the device. Make sure that there
are no leaks or damages.
