branches, rocks, mounds etc., the device can tilt or slip.
Only drive when you know about the terrain conditions and
terrain is free of obstacles.
Pay attention to bumps, holes, and other visible hazards.
Do not drive close to danger zones (e.g. walls, slopes,
steep declines, water edges etc.).
Danger due to uncontrolled slipping
Only park the device on flat surfaces.
Proceed with extreme caution in case the ground is wet or
loose. The danger of slipping is very high on cut growth, no
matter if it is wet or dry.
If the mower starts to slide you cannot regain control by actu-
ating the brake.
Uncontrolled sliding can occur because of:
slope angles that are too steep.
slippery ground.
poor tire grip.
speeding.
abrupt braking.
an inappropriate task for the device.
If the device tilts or slips
Never try to stop a tilting or sliding device. Severe injuries
can result.
Remove leaking fluids (oil, fuel, battery acid) from the
device and the floor. Deposit of contaminated soil environ-
ment friendly according to the local regulation.
Undetectable damage may have occurred to the device. In
case of malfunctions, there is a risk of injury. Have an au-
thorised service centre check the device.
Increased risk of tipping with additional
load
When the transport rack is loaded, there is an increased risk
of tipping. Please observe the information on the transport
rack.
Keep in mind that all attachments or additional loads increase
the risk of tilting.

Operating modes
The device can either be operated via remote control
(Remote Control = RC mode) or while riding on the device
(Manual Control = MC mode).
You can switch between operating modes at any time. How-
ever, it requires a great degree of knowledge to avoid faults
and risks. Please read the corresponding chapter carefully.
First, familiarize yourself with the device in the MC mode and
practise the procedures on a spacious, obstacle-free and flat
area.
Ride-on mode (MC):
We recommend working in the ride-on mode, for example,
to efficiently mow big, flat areas.
to precisely navigate around sensitive
obstacles.
to easily detect obstacles and foreign objects
and thus be safe from ejected parts.
to easily detect obstacles and foreign objects
and thus avoid damage of the device.
Remove control mode (RC)
We recommend working in the remote control mode, for
example,
when you want to protect yourself against
noise, physical strain, vibrations, exhaust
fumes, dust, sun, or rain.
at inaccessible places such as in the under-
growth, low branches or thorns.
on slopes.
to have a better overview of the danger area
and thus avoid accidents.
at the water’s edge or in the proximity of
edges with a risk of falling.
on soft, sensitive grounds.
to keep insects or pollen away.
Safety functions
To ensure safe operation at all times, the device is equipped
with safety functions. To make the engine and the blade run,
depending on the operating mode, certain requirements need
to be fulfilled. These requirements are described in the cor-
responding chapters.
Driving on steep terrain
Warning
Driving on the slope is dangerous. There is a tilting and
slipping hazard.
► Have skilled personnel who were trained by AS-Motor
show you the safe handling of the device before you
mow on steep terrain.
► Observe the safety instructions regarding mowing on
slopes and the danger area.
Move on slopes only when the differential lock is actuated.
Always check via the clinometer to see your device's sloping
angle.
Checking the slope
1. If the slope is unknown, check first in the RC mode.
2. On a level part, drive with disengaged blade parallel to the
slope.
3. Stop the device.
4. Read the cross slope on the clinometer at the rear of the
device.
5. If the slope is in the admissible range, move to a steeper
part and repeat the cross slope test.
6. In the MC mode, read the slope on the clinometer on the
tank.
Suitability on slopes in the MC mode:
Use the device in the ride-on mode (MC) only on less than
21° slopes.
Suitability on slopes in the RC mode:
Use the device in the remote control mode (RC) only on
less than 33° slopes.
When you are positioned sideways to the slope at an angle of
more than 33°, the horn of the device sounds at intervals.
Move on to flatter ground.
Oil pressure switch
22
Oil pressure switch
The oil pressure switch signals via the oil control lamp on the
transmitter when engine damage due to low oil pressure is
about to occur. 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 may be for the oil pressure switch to
signal this depends on the engine type, direction of inclina-
tion, and the oil level.
Oil pressure drop
When the device detects an oil pressure drop, the oil control
lamp on the transmitter lights up.
1. Move the device to a flat terrain in the vicinity.
2. Oil control lamp on the transmitter is off:
ð The device was in a too inclined position.
ð The oil pressure restored and you can continue to
work.
3. Oil control lamp on the transmitter lights up.
ð The oil pressure of your device is still too low.
If the oil pressure of your device is still too low:
1. Switch off the engine.
2. Check the oil level.
3. If the oil control lamp lights up even though the oil level is
sufficient, contact an authorised service centre.
Beware: If you drive for several minutes without oil pressure,
engine damage will result.
Differential lock
The differential lock connects the two rear wheels rigidly to
each other. This improves traction. Actuate the differential
lock when a wheel slips.
Always actuate the differential lock when moving downhill.
This improves the driving stability of the device. The risk of
sliding or swerving of the rear is reduced and safe braking is
possible.
Driving in curves while the differential lock is actuated is only
possible with limitations.
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 on the silencer poses a fire hazard.
Frequent engagement and disengagement of the clutch in-
creases wear of the blade drive belt and the blade brake. Es-
pecially in case of high grass, clutch engagement leads to
overload.
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 ser-
vice 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.
Set the cutting height so that the blade does not touch the
ground even in case of terrain unevenness.
Always set the blade to transport position when you do not
mow.
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 recom-
mend, 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.
Prior to starting
23
Prior to starting
Checking the oil level
Notice
Incorrect oil level can damage the engine.
► Prior to each use, check the engine oil level and the oil
level in the hydrostat (see Maintenance).
Observe the information in the operator’s manual of the en-
gine manufacturer.
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
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. Ob-
serve the safety instructions regarding the fuel!
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 pres-
sure is slowly reduced.
3. Open the tank cap carefully so that existing excess pres-
sure is slowly reduced and no fuel sprays out.
4. Fill the fuel tank.
5. Tightly close the tank cap again.
Checking and changing the battery of the
transmitter
When working, always carry an extra battery.
If the batteries in the transmitter are charged too low or the
batteries are unsuitable, these can be the consequences:
The range of the radio contact drops.
The radio contact becomes unreliable.
An Emergency stop is triggered.
The device cannot be operated any longer, also in the MC
mode.
Checking the battery

Adjusting the seat suspension
The seat suspension should be adjusted to the driver’s
weight and the terrain features. You will sit most comfortably
when the spring travel is fully made use of.
The seat suspension should be set as soft as possible to
keep it from going coil-bound during normal operation. You
can read the current setting from the scale on the seat.
If the seat goes coil-bound during normal operation, turn the
handwheel clockwise. The indicator moves towards 5. The
seat suspension becomes stiffer.
If the seat suspension is stiff during normal operation and
thus uncomfortable, turn the handwheel anticlockwise. The
indicator moves towards 1. The seat suspension becomes
softer.

of the engine. The manual contains all maintenance require-
ments and warranty conditions for the engine. If warranty
work on the engine is required, contact your authorised ser-
vice centre or the next authorised dealer for engines.
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.
Opening the engine cover
Warning
The engine cover can accidentally close.
► Make sure that the engine cover stays open while you
carry out work on the engine. Close the engine cover
immediately after you have completed maintenance
work on the engine.
Warning
Burn hazard from hot surfaces.
► Let the device cool down for at least 20minutes before
you open the engine cover.
1
To carry out maintenance work on the engine, slacken the
screws(1) and open up the engine cover.
Checking the engine oil level
Never allow the oil level to be too low otherwise the engine
can be damaged. Never fill in too much oil. Otherwise, there
is the risk that the oil enters and destroys the air filter.
For this, observe the attached operating instructions of the
engine.
Checking the spark plug
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 elec-
trode 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 operat-
ing instructions of the engine manufacturer).
Always check both spark plugs.
Maintaining the air filter
Warning
There is a fire and explosion risk due to cleaning agents.
► Never clean the air filter with flammable solvents.
Make sure that the air filter is always clean. A dirty air filter
reduces the engine power and leads to increased engine
wear and fuel consumption. Independent of the operating
hours, change the filter insert at least once a year. Do not op-
erate the engine without air filter.
For this, observe the attached operating instructions of the
engine.
Checking and charging the battery
Warning
Batteries can be dangerous.
► Keep children away.
► Never perform any changes to the battery.
► The battery is sealed and may never be opened.
► For all work on the battery or the battery cables, wear
safety glasses and gloves.
► If accidents with battery acid occur, always contact a
doctor.
Warning
Explosion hazard
When the battery is charged, explosive gases are gener-
ated. An explosion of the battery can result in injuries and
blindness.
► Keep open flames and ignition sources away and do not
smoke.
► Charge the battery only in well ventilated rooms.
Maintenance
45
Warning
Danger of chemical burn
Batteries contain acids. Contact with battery acid can res-
ult in blindness or serious burns.
► Always keep the battery upright and do not spill any bat-
tery acid.
► Avoid contact with skin and eyes.
► If battery acid comes into contact with eyes, immedi-
ately rinse the eyes with water.
Notice
Work on the battery can damage the receiver.
► Prior to work on the battery: Press the start-stop switch
on the transmitter and remove the key. Then switch off
the main switch.
If the starter does not get the engine going or only insuffi-
ciently, charge the battery.
The battery is maintenance-free and gas-tight.
Use electronically controlled charging systems. These char-
ging systems detect the connected battery and charge it with
the required charging current and terminate the charging pro-
cess when the battery is full.
Use a charger that is equipped with a 12 V connection for
standard norm outlets. Insert the plug for charging into the
standard norm outlet.
Charge the battery before you put the device away for winter
storage. A fully charged battery lasts for approx. 4 months
before it needs to be recharged.
Exchanging the battery
Warning
When you work on the battery, there is a risk of short cir-
cuit.
► Do not put any tools or metal objects onto the battery.
► When disconnecting and connecting the battery, ob-
serve the order of assembly steps.
Important: Only use original batteries.
You can buy original batteries from AS-Motor or your author-
ised service centre. Also observe all information in the oper-
ator’s manual of the battery (if existing).
Caution! Never confuse the plus and minus terminals.
1. Disconnect the black cable (-).
2. Disconnect the red cable (+).
3. Dismantle the battery from the device.
4. Mount the new battery into the device.
5. Connect the red cable (+).
6. Connect the black cable (-).
Hydrostat transmission
Warning
Risk of injury due to high pressure (up to 410bar) in the
hydraulic system.
► Check the hydraulic hoses for leaks, damage and chafe
points.
Warning
When oil leaks there is a danger of environmental pollu-
tion.
► Check the hydraulic drive system for leaks before and
after mowing.
Fig.33:
In warmed up condition, the oil level must be at “MAX” mark-
ing. In cold condition, the oil level can be somewhat below, in
hot condition the oil level can be somewhat above the "MAX"
marking.
There always must be oil in the compensation tank so that no
air can enter the hydraulic system.
Oil changes must be carried out by an authorised service
centre (see chapter Maintenance table).
Check if the gearbox fan is undamaged.
The hydrostatic drive generates a monotone working noise
that gets louder as the load is increased (e.g. in steep ter-
rain). If the working noise changes, if it gets irregular or very
loud, let the hydrostatic drive cool down and check the oil
level.
If the change working noise still exists, have the device
checked by an authorised service centre.
It is possible that the hydraulic system must be ventilated or
the oil must be changed. For refilling, only use fully synthetic
engine oil 5 W50.

Mulching mower Mulching mower – the time-saving alternative!
AS-Motor mulching mowers shred the grass to create such a fine mulch, almost an “invisible” fer-
tiliser, that sinks right away back into the lawn. Disposal of the cuttings is not required.
Professional lawn
mower
Professional lawn mowers with rear or side discharge for every requirement, even with all-wheel
drive, brake and reverse gear.
Brush cutter
®
An agile lawn mower for maintenance of extensive grassed areas. The Allmäher® reliably mows
and mulches metre-high grass, brushes and weeds.
Flail mower High grass with undergrowth, steep slope or extensive areas in unknown terrain? The movably
mounted flail blades of the AS-Motor flail mower give way to rocks and obstacles and chop the
cuttings several times over.
Ride-on brush cutter If extensive areas, weeds and undergrowth up to 1.2 m, the AS‑Motor all-wheel mowers are also
perfect for steep and even extremely steep terrain. Ease of use and high area performance com-
bined in one compact ride-on mower. For more safety, comfort and efficiency in difficult terrain we
have developed the innovative and the world’s first remote controlled ride-on mower.
Rotary mower The cost-effective alternative to the cutter-bar mower. Also ideal for feed production. The grass is
not shredded but deposited in straight rows as a windrow next to the machine.
Weed remover Careful and chemical-free weed removal. The AS‑Motor weed removers “WeedHex” mechanically
clean paved areas and curb stones from growing weeds – quickly, safely, and efficiently.
