SECTION 3 - MACHINE PREPARATION
3 - MACHINE PREPARATION
3.1 Packaging and endowment
The machine is supply with:
1 x Basic Unit X-Rot
1 x Radio Control
2 x Lithium battery for Radio control
1 x Battery charger
1 x Radio control’s hanging belt
1 x User Manual
1 x Engine user manual
1 x Rod (to replace the crawler)
Before to use the machine, check the fuel and engine’s oil level and read
carefully the instruction manual about the safety regulation and the proce-
dures to start and control the machine.
3.2 PRELIMINARY TESTS
Before using the machine for the first time, it is necessary to do the following
checks:
• Engineoillevel(seeCap.7.1.1)
• Fuellevelinthetank(seeCap.7.1.3)
• BatterychargeontheRadioreceiver(seeCap.7.1.5)
- The engine oil should be always on the mark of the upper level. Lack of
oil will decrease the engine performance on the slope.
- The fuel level should be near to the max but not reaching the collar of the
tank. In case of slope the fuel can spill out and create a danger of fire.
- The 2 battery set have to be charged before to start any work. One battery
should be enough for one day operation but the 2nd one should be available
in case of need.

SECTION 4 - COMPONENTS AND CONTROLS
4.2 ENGINE (fig.7-i)
The machine is equipped by a high quality petrol engine made in Japan and
designed to grant a long operating life. The engine is provided by an electric
start.TostarttheenginefollowtheprocedureofCap.5.2.
The engine is also provided by a forced lubrication system which help to work
inaslopingareas,neverthelessitishighlyrecommendnottoexceedthe35°.
The instruction of the max. angle are reported on the bottom of the radio con-
trol.
IMPORTANT
Do not leave the machine in the slope with the engine running. The
lubrication can be insufficient and cause the engine failure.
ATTENTION
Never stop the engine while the machine is on the slope. The engine
stop will cause the switching off of the drive motors and the lose of the
machine control.
 Thefirst50workinghoursrepresenttherun-inoftheengine.Duringthis
first period we recommend not to use the machine at the full power.
It is also necessary to leave the engine running for few minutes at the idle
speed for warming after starting. A sudden use at the max power just after
starting cause a thermal shock to the engine components.
4.2.1 AIR FILTER(Fig.7-n)
The engine is equipped by an air filter. In case of dry grass and dusty environ-
menttheairfilterhavetobecleanedveryoften(every2hours).Ifsomeflying
grassaretrappedbythenetoftherecoilstarter(Fig.7-i)itmeansthatprob-
ablyalsotheairfilterneedtobecleanedout.(seecap.7.1.2).Theclogging
of the air filter can cause a lose of engine power. In normal condition, the air
filter should be cleaned every day.
4.2.2 FUEL TANK(Fig.7-m)
Thefueltankhaveacapacityof10litreofpetrolandshouldassure4hoursof
operation. Before to start any work remind to fill up the fuel tank. A reserve of
fuelof3litres(markedbyapilotlightontheradiocontrol)warnthatitistime
to refuel. stop working and move the machine in a flat hard soil for fill it up.

I. SAFETY
15
SECTION 4 - COMPONENTS AND CONTROLS
DANGER
The engine stop can be dangerous in case of slope. the stop of the engine
cause the loosing of control of the electric motors. In case of slope the
machine could start to move downhill.
DANGER
Pay attention while refuelling: The gas of petrol are highly explosive. Do not
attempt to refuel if somebody are smoking or in presence of sparks or open
flames.
4.3 MOWER DECK (fig.7-p)
The mower deck has a special design to reduce the power required. It is con-
necteddirectlytotheenginebybeltanddisconnectedbyanEMclutch.
The engagement of the Mower can be done if the engine is at a suitable
speed.(seeCap.5.7).Thebladesystemdependfromthetypeofwork:multi-
cut for a perfect mulching result and a stronger blade for heavy duty opera-

tions. The cutting height can be adjust from
the remote control and it is visible from an
indicator on the right hand side of the ma-
chine(seeFig.8).FormaintenanceofEM
Clutch,BladesandtransmissionBeltplease
refertoCap.7.2.7.
4.4 ELECTRIC SYSTEM
The driving system of this mower is electric.
The alternator driven by the petrol engine
generates an electricity supply voltage of
48Vinarange(Extra-lowvoltage- ELV)
which carries a no risk of electrical shock.
The crawler are then driven by 2 brushless
electric motors controlled electronically by 2
inverter which follow a sophisticate software
that makes the machine easy to use and
flexible.
The electric cabinet on the back of the ma-
chine have a easy access to the radio re-
ceiverandtothefuseandrelaysboxes(Fig
9).Theelectricsystemhasawaterproof
grade of IP 54.

SECTION 4 - COMPONENTS AND CONTROLS
4.5 TRANSMISSION
The transmission of the power to the crawler are made by 2 strong and si-
lent gear reductors. The portal shape of the transmission allows to keep very
lowthecentreofgravityofthemachinewhichis15cmofftheground,only.
The technology of these electric motors grants the maximal torque also at a
standstill. These 2 features make this machine suitable to work in very sloped
ground. Moreover in case of electric power failure, a passive breakage device
save the machine from running downhill without any control.
4.6 REMOTE CONTROL
The remote control is a heavy duty and reliable unit which allow to carry out
all the controls and the adjustment of the machine. It works on a frequency of
2,4GHzwiththeTransmissiontechnologyAFA(AutomaticFrequencyAdjust-
ment)thatautomaticallyshifttoanewfreechannelincaseofdisturbsonthe

5.5 HOW TO DRIVE IN A SLOPE
In a slope it is recommend to drive in
alongitudinalwayand(ifpossible)
with the left hand side downhill.
To work on the slope area it is not
necessary to change direction
because the machine can work in
both direction. So the suggested path is A-B as represent in the
Fig13.
In case it is necessary to work
according to A-A path, it is provide
a"REVERSINGSWITCH"Fig12(H)
which make easier to drive as the
machine will follow the Joystick
direction.(seeFig14thedrive
direction with the 2 positions of the
switch(H)).
5.6 BRAKE SYSTEM AND PARKING
The machine is supplied with an
automatic e-motor brakes which stop
the machine while not driving. This
brake system works if the engine
runs and all the control systems
areworking.Forthisreason,ifyou
