Introduction & Features
Remember that :
Maximum coverage 400 sq.m.
However, it is a good idea to not exaggerate and bear in mind that gardens
that are more comp icated reduce the square meters covered by the robot.
Maximum s ope imit of 27°
The robot can mow this maximum s ope imit.
Remember that the main prob em is the uphi c imb when the robot arrives
at the border and is unab e to go back.

Start-up / Installation
Getting Started
Recharge the Robot
First, recharge the Robot. It wi come in handy at the end of insta ation for
checking the correct functioning of the awn mower.
Fix the garden
Before starting the Robot, the customer must be instructed on how to fix up
the awn.
The most common prob ems are sma ho es, sma toys, and rocks, basica y
a objects which cannot be detected as an obstac e and which pass under the
body of the robot and may be picked up by the cutting b ade.
Sprink er system
Watch out for the sprink er system; make sure the sprink er heads do not
protrude from the grassy surface. This may damage the cutting b ade.
Marking boundaries
The garden must be checked and adjusted so that the robot has enough
space for recognising when there is no grass. Carefu y fo ow the above
points for the correct and safe use of the robot.
The robot moves in both directions and changes its forward direction on y if
the fo owing events are verified
- No grass.
- Gradua s ope exceeding 27-30°.
- Rapid s ope exceeding 15-20°.
- Knocks to the body detected by the current of the whee motors.
- Too much adsorption of the whee motor.
The figures to the eft show how to mark the boundaries of the awn so that
the robot does not go outside the area to mow.
If there are areas which are dangerous for the robot (e.g. a poo , pond, abyss,
stairs going down, a sudden and steep descent) adjustments must be made to
prevent the robot from being damaged. The first figure shows an incorrect
situation.

The figure be ow shows a correct insta ation.
Turning off the cutting b ade. The robot turns off the cutting b ade due to
the fo owing reasons
- Ta grass or s ow motor speed.
- A hand e was touched.
- The robot exceeded a 30° s ope
- The inc ination of the robot has changed too quick y.
- If both hand es are touched, the robot wi stop the whee s and cutting
disc.
Power Supp y Unit
Position the power supp y unit according to the fo owing ru es:
- Position it in an area not exposed to water and rain
- Preferab y, indoors
- If p aced outdoors, make sure it is p aced in a we -venti ated box
away from direct sun ight and water.
- It must be positioned in a we -aired area

User interface (LED)
The keyboard consists of only two keys, an ON/OFF key and a key to start and stop the robot.
The LED always shows the status of the robot. The LEDs relating to the batteries show their charge level
when the robot is running and when it is in Pause.
Two LEDs must be checked when the robot stops. The “ON” LED and the “Pause” LED
During normal operating conditions the LED (ON) must be turned on and steady and the LED (Pause)
shows the reason why the robot has stopped.
The robot can be starter by activating or deactivating the grass detectors and/or the curb drop off detectors

- 6 -
If the robot breaks down, the LED (ON) will flash indicating the reason for the malfunctioning. As shown
in the table below.
WHEN A ROBOT STOPS, THE FIRST
THING TO UNDERSTAND IS THE
CONDITION OF THE “ON” LED AND
THE “PAUSE” LED
Attention !!! : When the robot is switched
on if all the leds are switched on, it means
that the final test hasn’t been achieved. We
must make the final test as described here
below.

List of errors
The robot does not turn on.
Reasons
- Interna fuses are burnt
- Prob ems connected to the ON key
- Batteries are comp ete y f at
So utions and checks
- Connect the robot to the recharger for a few minutes
- Check the inside fuses
- Check the charging eve of the battery
- Disconnect the battery, reconnect it and try again. Reset the board.
- Open the robot and assemb e the body in reverse with the ON key
positioned in the Start connector. (For safety purposes, run the test
without the b ade). Obvious y, the contro s wi be inverted but this
operation a ows understanding if the key is broken or if the board
is broken.
Has the prob em not been so ved? (Spare parts to check)
- Motherboard
- Keyboard
- Battery
- Cab ing
The robot turns on but the Start key does
not work and the robot does not start.
Reasons
- Keyboard is defective
- Robot is charging
- Motherboard is broken
So utions and checks
- If connected, disconnect the robot from the recharger
- Disconnect the battery, reconnect it and try again. Reset the board.
- Press the “Start” key is pressed, the sound of a disconnecting or
connecting re ay shou d be heard. If this sound is heard, it is ike y
that the motherboard thinks it is being recharged and therefore the
robot does not start.
- An additiona check for understanding if the prob em re ates to the
motherboard or to the keyboard invo ves opening the robot,
assemb ing the body in reverse with the ON key positioned in the
Start connector. (For safety purposes, run the test without the
b ade). If the robot turns on when the "Start" key is pressed, this
means that the key is working

The robot a ways stays on.
Reasons
- Keyboard is defective
- Robot is charging
- Motherboard is broken
So utions and checks
- If connected, disconnect the robot from the recharger
- Disconnect the battery, reconnect it and try again. Reset the board.
- An additiona check for understanding if the prob em re ates to the

assemb ing the body in reverse with the ON key positioned in the
Start connector. (For safety purposes, run the test without the
b ade). If the robot turns on and off when the “Start” key is
pressed, then this means that the key is working and the fai ure
shou d be in the motherboard.
Has the prob em not been so ved? (Spare parts to check)
- Motherboard
- Keyboard
The robot occasiona y pauses for no
reason ( ow batteries, awn moved, no grass
or error)
Reasons
- Keyboard is defective
- Hand es came into contact with wet objects
So utions and checks
- Try the robot with another body and then with different
Start/Pause keys.
- Run (on y temporari y) the robot with the cab es of the hand es
disconnected from the motherboard. Of course, this test reduces
the safety of the product. It is not a so ution but on y a test.
The robot occasiona y turns off and when
it restarts the batteries are not ow.
Reasons
- Keyboard is defective
- Battery
So utions and checks
- Try the robot with another body and then with different
Start/Pause keys.
- If the prob em depends on the battery, the test is not simp e. The
robot can be started if the b ade is b ocked, but this is not a simp e
test to execute. The safest procedure is to try the robot with a fu y
charged battery.
B ade motor frequent y turns off
This does not necessari y mean that there is something wrong with the
robot.
Norma reasons.
- S ope is greater than 30° or s ope of 20° is reached too quick y.
- Grass is too ta , too much strain on the motor
- A hand e was touched.
- No grass or zone with grass ower than the 6 sensors
Reasons due to defective or worn parts.
- B ade motor encoder
- Motor cutting brushes worn
- Motherboard with fau ty hand e sensitivity.
So utions and checks
- Start the robot norma y. If the modu ation functions correct y, this
shou d mean that the encoder is functioning.
- Open the robot, disconnect the cab ing of the hand es. Retry the
robot without this functiona ity (if the prob em is reso ved contact
ZCS)
- Try the robot without the cutting disc. (If the prob em is reso ved,
the fau t cou d be in the cutting motor or the worn brushes).
Has the prob em not been so ved? (Spare parts to check)
