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 on 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.
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.
Devices with blade speed lever
In case of extreme high and thick growth, we
recommend to set a low engine speed and to
reduce the driving speed.

17
Prior to starting
Fuel used (4-stroke devices)
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.
Check engine oil level (4-stroke
devices)
Beware! Prior to each use, check the engine
oil level (see operating manual of the engine
manufacturer).
To ensure a sufficient oil supply for the 4-
stroke engine and to avoid engine damage,
devices without oil pressure switch may only
be used for a slope inclination of up to 20°.
Fuel used (2-stroke devices)
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. Do not use
fuels with more than 10 % ethanol (e.g. E15,
E85).
Only use fully synthetic two-stroke oil intended
for mixing in ratio 1:50. Do not use any mineral
two-stroke oil.
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“ of 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”, “ASPEN 2-stroke” and “Oest Oecomix”
can be used. No guarantee can be given for
operation of the device with other fuels and
oils!
Do not use mixtures with more oil than 1:50
(e.g. 1:35).
Too much oil results in carbon deposits and re-
duces the service life of the engine.
Only use the fully synthetic two-stroke oils ex-
plicitly 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.

18
Tanking up
Warning
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!
Warning
The fuel tank at the engine is not connec-
ted.
Filled fuel can run out and ignite.
► Never fill fuel into the tank on the engine.
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.
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.

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 hori-
zontal direction, it is necessary to always lock
the wheel.

Setting the blade speed
Devices with blade speed lever
You will achieve a good result of cutting and
mulching with a high blade speed and medium
driving speed.
When the blade speed is low, the tractive
power of the blade is especially high and the
noise level lower.

Oil pressure switch
Devices with oil pressure switch
The oil pressure switch ensures that the en-
gine is not damaged when the device is used
in steep terrain.
The oil pressure switch switches off the engine
when damage to the engine may occur due to
lack of oil pressure. This may occur when:
– Oil level is too low.
– The device is in too steep a sloping position
while in steep terrain.
How steep the gradient for the oil pressure
switch to switch off the engine may be de-
pends on the engine type, direction of inclina-
tion, and the oil level.
In order to restart the engine, push the device
while in idle state to terrain that is less steep.
In every case, check the oil level.
