fasten the tension belts exclusively as shown
in the illustration. Do not overtighten the ten-
sion belts.
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
hazard.
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
The engine must be run on a mixture of petrol
and two-stroke oil.
For possible mixing ratios, see chapter Mixing
ratios fuel.
Use unleaded petrol (octane rating at least
ROZ 91). You can use E10 petrol. Do not store
E10 petrol longer than 30 days.
Always use synthetic or, even better, fully
synthetic two-stroke oil. Mineral two-stroke oil
is not recommended.
AS-Motor recommendation:
Fully synthetic two-stroke oil TITAN 2T 100S in
ratio 1:100.
Your benefits:
–Halve oil consumption compared to 1:50-
therefore more environmentally and cost
friendly.
–Optimum protection of the engine for a long
service life.
–Low engine wear.
–Maximum engine performance.
You can buy Fuchs “TITAN 2T 100S“ from
your AS-dealer:

Notice: You can find on the market ready
mixed two-stroke fuels. Based on our experi-
ence, the ready mixed fuels “STIHL Motomix
1:50” and “ASPEN 2-stroke” can be used. No
guarantee can be given for operation of the
device with other fuels and oils!

15
Do not use mixtures with more oil than 1:50
(e.g. 1:35).
Too much oil results in carbon deposits and
reduces the service life of the engine.
Only use the synthetic two-stroke oils explicitly
intended for mixing.
Use of engine oils or even waste oil results in
engine damage.
No warranty is given in these cases.
Storing fuel mixture
The fuel mixture ages and can cause engine
damages. Only mix as much fuel as you are
going to use up during the next mowing.
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.
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.
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.
1
3. Slacken the wheel bolt (1).
4. Pull out the wheel together with the cover
plate.
4
2
3 5
5. Screw it back in in position (2) or (3).
(2) = low cutting height
(3) = higher cutting height.
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.

16
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).
Height of steerable front wheel
1. Reach with your hand below the guide bar
of the steerable front wheel and press with
the ball of your thumb the lever of the cut-
ting height adjustment downwards.
2. Lift or lower the guide bar to the desired

Preparations
Caution!
Risk of injury.
Guide bar can snap back.
To provide secure stand, place the
guide bar onto the ground.
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. Release the guide bar by pulling the tie rod
and flip the guide bar forward (do not crush
the Bowden cables).
5. Tilt the device backwards onto the notching
segment of the bar as shown in the figure.
6. Put the guide bar onto the ground.
Cleaning the device
Depending on use, clean the device thorough-
ly, especially the bottom and the knife.
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
components at the silencer are clean.
For cleaning, use a hand brush. Remove
stubborn 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 aggres-
sive 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.

20
Immediately replace damaged or worn parts,
especially covers, protection skirt, silencers or
fuel tank (authorized service centre).
Check all parts 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.
Grease lubrication
1
A grease nipple (1) is attached to the steering
tube of the steerable front wheel.
1. Clean the grease nipple.
2. Lubricate the grease nipple with a hand
grease gun (1-2 strokes plastic compatible
grease).
3. Remove any excess, squeezed out grease
from the bearings.
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.
To ensure a long service life of the engine,
sufficient engine cooling is required.
Keep the
- engine cover (ventilation grid),
- silencer (protective grid) and
- cooling fins of the engine
clean at all times.
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 “Technical data”). Make sure that the
insulator around the electrode is not damaged.
Never use a damaged spark plug.
Tighten the spark plug with the torque indicat-
ed in the technical data.
Maintaining the air filter
Danger!
Cleaning agents pose a fire and
explosion hazard.
Never clean the air filter with flam-
mable solvents.
Caution!
A cleaning of the air filter with
compressed air damages the filter
fabric and the air filter becomes
useless.
Change the air filter when it is dirty.
Caution!
When you use air filters from ac-
cessory suppliers, the engine can
be damaged.
Only use the original AS-Motor air
filter cartridges.
Make sure that the air filter is always clean. A
dirty air filter reduces the engine performance
and leads to increased engine wear and fuel
consumption. Irrespective of the operating
hours, change the filter insert at least once a
