When transporting by vehicle, secure the device against rolling, sliding, tilting, and fuel and oil leakage.
Information on mowing
Prior to mowing, check your device for completeness, 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 frequently 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.
Use tension belts to secure the device.
Beware:
To avoid damage to the device, fasten the tension belts exclusively as shown in the illustration. Do not overtighten the tension belts.
14
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.

Notice:
You can find on the market ready mixed two-stroke fuels. Based on our experience, 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!
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.
15
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.

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.
Prior to all maintenance and cleaning work:
1. Let the device cool down for at least
20 minutes.
Do not clean the device with water spray or high-pressure cleaner! Do not use any aggressive cleaning agents.
20
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.
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 indicated in the technical data.
Maintaining the air filter
Danger!
Cleaning agents pose a fire and explosion hazard.
Never clean the air filter with flammable solvents.
21
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 accessory 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 year. Cleaning the air filter is not possible. Do not operate the engine without air filter.
Beware!
During filter change, accumulated dirt in the air filter can get into the carburetor and damage it.
1. Screw off the air filter lid.
2. Carefully pull out the filter element. Make sure that no dirt from the inside of the air filter housing enters gets into the carburetor.
3. Close the carburetor with a clean cloth.
4. Clean the inside of the air filter housing carefully.
5. Remove coarse, loose dirt from the filter element by knocking it off. Replace the filter element if the dirt is extensive or caked on.
6. Remove the cloth from the carburetor.
7. Re-insert the filter element.
8. Screw the air filter lid back on.
Checking rear brake
Danger!
If the brakes are incorrectly adjusted, the device can roll away.
Make sure that the brake is always functioning properly.
1
1. Put the device on a non-slip surface (e.g. concrete or asphalt).
2. Switch off the drive.
3. Actuate the rear brake.
4. Try to move the device.
If the rear wheels lock, the rear brake is correctly adjusted. If you can push the device, the rear brake must be re-adjusted.
Re-adjusting the rear brake:
Turn the adjusting screw (
1
) at the brake lever until the wheel lock while the brake is applied.
When the adjustment is completed and the braking performance still has not improved, have an authorised service centre check the device.
Checking the drive
1. Put the device on a non-slip surface (e.g. concrete or asphalt).
2. Switch off the engine.
3. Actuate the drive.
4. 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.
22
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 improvement after the adjustment, have the device checked by an authorised service centre.
Checking the blade
Danger!
Improperly mounted and maintained blades pose a severe injury hazard.
Work at the blade shall only be performed by an authorised service centre.
Wear sturdy gloves when you check the blades.
Work on the blade requires special qualifications because an unbalance test is required and the torques must be observed.
Check the blade and all fastening parts for wear, damage and cracks
– before and after each mowing operation.
– when there are significant changes.
All blade parts shown and their fastening parts must be changed
– when damage or cracks were found.
– At least once a year or every 50 operating hours, regardless of whether there is wear or not. Material wears out, gets cracks which can endanger persons or property.
Vibrations indicate that
– the blade is worn excessively on one side or
– damage of motor or cutting unit mount (e.g. rubber elements).
Improperly sharpened blades increase the device load and result in fatigue cracks and breakage.
Ejected pieces can cause severe injuries.
Blade change
1
2
1
2
It is absolutely necessary to change the blade:
– When one of the wear markings (
1
) was reached. Original blade are engraved with wear markings (marking in form of a ballshaped imprint on the rear side of the blade).
– When the thickness of the blade at the rear edge of the vane (
2
) or at another point is below 1 mm (exception: cutting edge).
Original blade
An original AS-blade is engraved with:
AS GXXXXXXXX or EXXXXX
This corresponds to the spare part number.
When using the device on sandy and abrasive grounds, the wear at the blade is high. A special blade was developed for these applications
(for abrasive ground blade, see accessories).
Checking engine brake
Check the function of the engine brake by switching off the engine. The blade must come to a standstill from full speed within less than
7 seconds. Contact an authorised service centre if this is not the case.
23
