Risk of injury due to the heavy
weight of the device. The device
can fall over and fall down and
cause severe injuries.
Observe the following notices.
Transport the device on a freight vehicle or a
trailer which is designed for a carrying capacity
of at least as great as the empty weight of the
device.
Prior to transport, let the device cool down for
at least 20 minutes. Close the tank ventilation
and the fuel valve.
For transport, you can fold up the handlebar.

Information on mowing
Prior to mowing, check your device for com-
pleteness, proper functioning, and cleanliness.
A dirty ventilation grid can damage the engine
and a dirty protective grid at the silencer poses
a fire hazard.
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.

13
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
regularly (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
performance.
To avoid blockage during the ejection of grass,
we recommend, for flat terrain, to proceed
according to the mowing patterns. Mulch is
shredded into much smaller pieces when you
mow the terrain once again in the opposite
direction.
If the grass is extremely high, mow twice at
different cutting height settings.
Prior to starting
Fuel
As fuel, use unleaded petrol (see operating
instructions of the engine manufacturer).
You can use E10 petrol. Do not store E10
petrol longer than 30 days.
Tanking up
Danger!
Fuel is ignited by hot engine parts.
Prior to filling up, switch off the
engine and wait for at least
20 minutes until the engine has
cooled down. Observe the safety
instructions regarding the fuel!
Filling in the fuel:
1. For filling, use a canister with a filler spout
or use as funnel.
2. Open the canister carefully so that the
existing overpressure is discharged slowly
and no fuel spurts out.
3. Open the tank cap carefully so that the
existing overpressure is discharged slowly
and no fuel spurts out.
4. Fill the fuel tank.
5. Screw the tank cap on tightly.
Checking the engine oil level
Attention! Prior to each use, check the engine
oil level (see operating instructions of the
engine 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.

14
1
1. Switch off the engine and wait until the
blade comes to a standstill.
2. Pull the lever (1) upwards and turn it until
the desired cutting height is reached.
Locking steerable front wheel
On flat terrain, it is more comfortable to leave
the front wheel free to pivot. If you mow in
horizontal direction, it is necessary to always
lock the wheel.
1
Releasing steerable front wheel
Pull off the spring cotter (1) and insert it into
the hole at the handlebar console.
Locking the steerable front wheel
Insert the spring cotter (1).
Starting
Danger!
During startup, there is a risk of
injury caused by the rotating blade.
Make sure that no one is within the
danger zone of the blade. Do not tip
the device over to one side during
startup.
Danger!
If after startup the carburetor does
not close properly, fuel will overflow
and a fire hazard occurs.
Close the fuel valve and contact an
authorised service centre.
Starting the device
1. Place the device onto a flat surface, not in
high grass.
2. Open the fuel valve and the tank ventila-
tion.
3. Plug on the spark plug connector.

Oil pressure switch
The oil pressure switch of the engine shuts off
the engine if damage of the engine caused by
inadequate oil pressure is likely to occur. This
can be the case when:
–The oil level is too low.
–The device is in an extremely inclined posi-
tion in excessively steep terrain.
To restart the engine, the device must be
positioned on an even surface. Always check
the oil level.

Preparations
Prior to all maintenance and cleaning work:
1. Let the device cool down for at least
20 minutes.
2. Pull off the spark plug connector.
3. Close the fuel valve and the tank ventila-
tion.
4. For work on the bottom of the device, tilt
the device to the silencer side.

Cleaning the device
After each use, you should clean the device
thoroughly, especially the bottom side and the
blade.
Stuck grass or dirt affect the grass discharge
and the cutting quality. For a sufficient engine
cooling, keep the engine cover, ventilation grid,
and the engine clean.
Fire hazard! Pay special attention so that
components at the silencer are clean.
For cleaning use a hand brush. Remove stub-
born soiling with a wooden or plastic spatula.
Clean the outer housing parts with a cloth.
Do not rinse off the device with a water jet or
high pressure cleaner! Do not use aggressive
cleaning agents.
General inspection
To ensure proper working order of the device,
regularly check all nuts, bolts, screws, fuel line
connections, air filters, etc. for firm seating.
Check the ignition cable and the spark plug
connectors for damages.
Change the damaged or used parts especially
covers, protection skirt, silencer, or fuel imme-
diately (authorised service centre).
Chain lubrication
The chains on the right and left of the differen-
tial lock must be lubricated on a regular basis.
We recommend the use of 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.
Maintaining the engine
Danger!
If the speed of rotation is set too
high, objects can be ejected. The
engine can be damaged and noise
pollution increases.
Do not change the basic setting of
the carburetor or the speed control.
The operating instructions of the engine are
prepared by the engine manufacturer. They
contain the maintenance instructions and the
warranty conditions for the engine. If warranty
work for the engine is required, please contact
your authorised service centre or the nearest
authorised engine dealer.
To ensure a long service life of the engine,
sufficient engine cooling is required.
Keep the
- engine cover (ventilation grid),
- silencer (protective grid) and

20
- cooling fins of the engine
clean at all times.
Checking the engine oil level
For this, observe the attached operating in-
structions of the engine.
The oil level must remain between the two
markings of the oil dipstick. Make sure that the
oil level is never below the bottom marking;
otherwise the engine can be damaged. Never
fill in oil above the top marking. Otherwise,
there is a risk that the oil enters and destroys
the air filter.
Checking the spark plugs
Danger!
The ignition system generates an
electromagnetic field.
Wearers of pacemakers must not
work on live parts.
Soiled spark plugs reduce the engine output.
Clean the electrode of the spark plug with a
brass wire brush. Check the electrode gap
(see operating instructions of the engine manu-
facturer). Make sure that the insulator around
the electrode is not damaged. Never use a
damaged spark plug.
Tighten the spark plug using the correct torque
(see operating instructions of the engine manu-
facturer).
Cleaning the air filter
Danger!
Cleaning agents pose a fire and
explosion hazard.
Never clean the air filter with flam-
mable solvents.
Always make sure that the air filter is clean. A
dirty air filter affects the engine output and
increases the fuel consumption. Independent
from the number of operating hours the filter
inserts should be changed at least annually.
Do not operate the engine without air filter.
For this, observe the attached operating in-
structions of the engine.
Checking the drive
1. Put the device on a non-slip surface (e.g.
concrete or asphalt).
2. Switch off the engine.
3. Set the switching lever to a forward gear.
4. Actuate the drive lever.
5. Try to pull the device backwards.
If the rear wheels lock, the drive is correctly
adjusted. If you can pull the device, the drive
must be re-adjusted.
1
Re-adjusting the drive
Turn the adjusting screw (1) at the drive so that
the wheels lock, while the drive is actuated,
when the device is pulled. If there is no im-
provement after the adjustment, have the
device checked by an authorised service
centre.
Checking the parking brake
1. Put the device on a non-slip surface (e.g.
concrete or asphalt).
2. Switch off the engine.
3. Switch the switching lever to neutral posi-
tion.
4. Try pulling the device backwards.
If the rear wheel lock, the parking brake is
correctly adjusted. If the device can be easily
pulled backwards, the parking brake must be
re-adjusted. Contact an authorised service
centre to do so.
