The motor must not be started:
– When fuel was spilled.
– In closed or badly ventilated rooms (danger of poisoning!).
– In the MC mode: When other persons are in close proxim-
ity.
– In the RC mode: When you or other persons are in close
proximity.
Risk of injury when the blade is running
Switch off the blade and wait until the blade stops
– when you drive on surfaces other than grass.
– when you do not mow.
– before you enter the danger area.
– when you cannot overlook completely the area to be
mowed.
– when the device must be manoeuvred out of a dangerous
position.
– when the trafficability of the area to be mowed is too un-
safe.
Risk of injury when the motor is running
Switch off the engine, wait for the blade and the engine to
stop and remove the key at the start-stop switch
– before you transport the device.
– before you step away from the device, even for just a short
time.
– before you clean or check the device or before you carry
out work on the device.
– before you unblock or unclog the discharge area.
Risk of injury due to uncontrolled rolling
In the MC mode, actuate the parking brake after each stop
and before shutting off the engine. By doing so, you can pre-
vent the device from rolling away in an uncontrolled way.
In the RC mode, never switch off the engine via the main
switch. Otherwise, the parking is not activated any longer and
the device can roll away.
Risk of burns
Do not touch the muffler, the engine, and the gearbox. These
parts become very hot during operation and you can get
burned. If a jumpy movement occurs, the risk of additional in-
juries can result.
Prior to mowing
Personal protective measures
During mowing, always wear safety shoes with
good grip and long trousers. Do not mow with open
sandals or while shoeless.
Wear safety gloves to protect yourself against injur-
ies and vibrations.
Noise is causing health problems. Use personal
ear protection to avoid hearing damage. Wear
safety glasses and headgear.
Ask your specialised dealer about suitable protective equip-
ment.
Preparing the mowing area
Prior to mowing, carefully check the perimeter of the lawn.
Remove rocks, pieces of wood, bones, wires, and other ob-
jects that could be picked up and thrown out by the device.
Use caution when mowing
Risk of injury
Stay within shouting distance to other people who can help
you in case of an emergency.
Danger!
Risk of injury caused by thrown out objects.
Never mow while persons, children, pets, or prop-
erty are in the vicinity.
Make sure that neither the operator of the device nor other
persons are in the danger area.
Keep your hands and feet away from the rotating parts.
Only mow during daylight or with adequate artificial lighting.
Never mow in the event of uncertain weather conditions and
risk of lightning.
Be especially carefully when mowing on soft ground, nearby
landfills, ditches and dikes.
Do not transport any person on the device.
Be extremely cautious when moving in reverse.
Pay attention to traffic when working close to roads.
Vibrations
If you use the device over a longer period of time, the vibra-
tions can cause circulatory disorders. A generally accepted
usage time cannot be determined.
– Use gloves.
– Change between MC mode and RC mode.
– Take breaks on time.
Have an authorised service centre check the device
– when the blade has hit an object.
– if the device starts to vibrate unusually severely.

Safety instructions
10
Mowing surfaces with fire hazard
– Carry a sufficient amount of suitable extinguishing media.
– If the device leans too much to the side, fuel can leak from
the carburetor or the tank. This presents a fire hazard!
– Observe the moved area even after mowing to make sure
that no fire breaks out.
To prevent a fire hazard, always keep the following compon-
ents free of dirt, grass, hay, leaking oil, grease, etc.:
– engine, ventilation grid
– silencer (manifold, protection, spaces)
– battery, cable connections, electric drive units
– area around the fuel tank
– belt drives
Caution when mowing slopes
Danger!
If the device, while in use, stops in steep terrain or
the engine cuts out, the device can roll away.
Immediately actuate the parking brake to prevent
the device from rolling away.
Observe the information regarding the oil pressure switch in
chapter Starting.
Sliding and tipping risk
Danger!
Mowing on the slope is dangerous. There is a tilting
and slipping hazard.
Please observe the following information.
– Use the device in the ride-on mode (MC) only on less than
21° slopes.
– Use the device in the remote control mode (RC) only on
less than 33° slopes.
– Observe the notices for the danger area and the operating
modes.
– Never unlock the drive at the slope because the device can
roll away.
– Always mow uphill and downhill, avoid mowing in hori-
zontal direction.
– Never drive on a slope that you cannot drive up backwards
without sliding.
– Be extremely cautious when changing the direction.
– Do not turn on a slope.
– Prior to entering the slope, always actuate the differential
lock. Move on slopes only when the differential lock is actu-
ated.
– Always keep the speed low when moving on slopes.
– Do not start abruptly and do not brake abruptly.
– In the MC mode, hold the steering wheel tightly so that the
device does not swerve.
– In both operating modes, drive with the bow raised. If the
device tips over, the rollbar can prevent the device from
overturning.
When the uphill wheels encounter obstacles such as roots,
branches, rocks, mounds etc., the device can tilt or slip.
– Only mow when the terrain is clear of obstacles and you
are familiar with it.
– Pay attention to bumps, holes, and other visible hazards.
– Do not mow close to danger zones (e.g. walls, steep de-
clines, 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.

Operating modes
The device can either be operated via remote control (Re-
mote 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 ex-
ample,
– 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.
– in steep terrain.
– 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 run, depending on
the operating mode certain requirements need to be fulfilled.
These requirements are described in the corresponding
chapters.
