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. Do not mow
your lawn too low in dry and hot conditions be-
cause the lawn is susceptible to sun and heat
damage and will look unsightly!
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 collect the grass without blockage, we re-
commend, for flat terrain, to proceed according
to the mowing patterns.
If the grass is extremely high, mow twice at dif-
ferent cutting height settings.
Mowing with mulching accessory
The mulch layer that results from mowing
should not be thicker than 1-2 cm. Otherwise,
during the decomposing process, a thick layer
forms that negatively effects the important air-
gas-exchange of the soil. In addition, the
mower can clog.

18
If you mow once a week or every other week,
we recommend a cutting height of 7-8 cm. If
you desire a lawn that is lower, you need to
mow more often. As a rule, you should not be
cutting off more than 1/3 of the length of blade
of grass.
Prior to starting
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

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.
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)
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°.
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 the 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 cutting height can be adjusted in 1 cm in-
crements from 3cm to 8cm.

1. Switch off the engine and wait until the
blade has come to a standstill.
2. With the adjusting lever(1) adjust each
wheel to the same cutting height. While do-
ing so, adjust wheel after wheel only by
one position at a time.
Setting the cutting height
Under high load, adjust the cutting height by
tightening the screw(2).

Starting
Danger
Danger of electric shock from live cables on
the mowing area. Live cables can be dam-
aged during mowing and cause an electric
shock or short circuit.
► Make sure that the mowing area is free
of live cables.
Warning
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.
Warning
Danger of poisoning due to poisonous ex-
haust gases.
► Do not operate the engine in closed or
insufficiently ventilated rooms.
► Please observe the safety instruction re-
garding the poisoning risk.
Warning
If after startup the carburetor does not close
properly, fuel will overflow and a fire hazard
occurs.
► Close the fuel valve and contact an au-
thorised service centre.
