Intended Use
The MowRo Lawn Mower has been designed for residential lawn mowing
up to 0.25 acre in area. It is not suitable for lawns with grades
greater than 30°. Do not use the MowRo for any purpose
other than for which it was designed. Any other use is unauthorized
and may result in serious injury.
Personal Protective Equipment
Always have the MowRo stopped before lifting, moving or
transporting the MowRo. When handling the MowRo Lawn
Mower it is important to avoid the blades that are two sided
and double edged and therefore extremely sharp. It is
recommended to wear safety gloves to make adjustments
to the MowRo or when changing the blades or blade disc.

Planning and Laying the Boundary Line
Laying Boundary Lines
In order to make the Robot Mower mow within the desired
area – and only that area – you need to mark the area by means
of boundary wiring. Remove all foreign objects, rocks, roots,
etc. that may interfere with the Robot Mower’s operation in the
mowing area. Large objects such as trees, swings sets, ponds, etc. should
be encircled by the boundary line. The boundary wire line needs
to be laid out in a continuous line (see Figure 2 on following page).
Route the boundary line around objects using a minimum of
100° angles (135° angles are recommended). Keep the boundary
line at least 30cm (12”) away from any: walls, drop-offs, or uneven
edge. If the lawn is level with the edge of the grass set the wire 10cm
(4”) away from the edge. Do not allow the boundary wire to
cross itself.
The boundary line should be placed at the root level of the grass
(see Figure 1). Secure the boundary line into the ground and
anchor with the boundary stakes. Place a stake approximately
every 3 feet.
greater than 30°. On slopes steeper than 30° the robot’s sensor
will shut the mower off.

Docking Station Installation
Avoid placing the docking station in a corner of the lawn or in low-lying
areas where the docking station or the Robot Mower may be damaged
by puddles, or under a high tree due to the risk of lightning.
Note: It is important that the adapter and the electrical plug are always
kept dry!
The docking station must have 6.5 feet of free space in front of it so the
Robot Mower can return to charge or when mowing is complete (see
Figure 3). The docking station must be located on level ground for correct
operation.
Connecting the Boundary Line to the Docking Station
Remove the terminal cover located on the back of the docking station. Insert the
end of the boundary wire into a blue T- clip and use a pair of pilers to press the
clip on the wire until you hear a click. Repeat this action on the other end of the
wire. Insert the wire that leaves the docking station into the negative (-) metal
prong. Connect the wire that comes from under the docking station to the
positive (+) metal prong. Proceed to plug in the docking station and confirm
the LED is a solid GREEN light. If the LED is flashing RED and GREEN confirm all
of your docking station connections are securely inserted and the boundary
wire does not have any cuts or breakage.

on the mower is wet. The rain sensor consitsts of two small metal circles that
are located to the left of the control panel and the external shell of the mower.
When the rain sensor is engaged, the mower will immediately find the boundary
wire and return to the docking station. Once the sensor is dry, the mower will
begin operation again.

17
Sensors
Obstacle/Contact Sensor
When the Robot Mower meets an obstacle, it will reverse and
a new path within 10 seconds, the robot will shut down and it
will require a manual restart to continue operation.
Rain Sensor
In case of heavy rain, the Robot Mower will automatically return
to the docking station. It will automatically start mowing the
next day at the time originally scheduled.
Lift Sensor
This sensor is placed close to the wheels and measures the
gravity of the wheels. If the Robot Mower is lifted manually or if
both wheels run into a hole, the robot will shut down and must
be restarted manually.
Tilt Sensor
A 6-axle sensor is integrated in the Robot Mower to measure
the tilt angle in all directions. If the tilt angle exceeds 30°,
the cutting motor will stop immediately but continue driving
(see Figure 7). If the angle decreases to less than 30° within
10 seconds, the cutting motor will restart automatically. If,
however, the angle does not decrease within 10 seconds the
mower will shut down and will require a manual restart.

Maintenance and Storage
Cleaning the Robot Mower
Lift the front and rear covers and remove any collected debris, grass
clippings and dust using a soft brush, vacuum or damp cloth. Repeat for
the bottom side of the robot using care when handling the blade disc and
blades. It is important to keep the blades free from accumulated grass
clippings to ensure proper operation of the robot mower. Ensure all
retaining screws are secure.
Clean and brush the contacts on the robot mower and the docking
station charging arms with steel wool or emery paper.
Cleaning the Docking Station
Remove dirt, grass and other debris from the docking station base plate
on a regular basis.
Blade Replacement
The Robot Mower blades are accessible when you turn the mower
upside down (see Figure 8). Blades have two edges and two sides. The
blades can be turned over one time before replacing. Blade replacement
is indicated when grass shows prominent white edges after cutting or
the mower makes excessive vibration noise. Turn all three blades over or
replace all three blades by unscrewing the three retaining screws.

DANGER
Storage
Disconnect the docking station from the AC power adapter. Remove
the ends of the boundary wire from the docking station. Turn the power
switch off on the Robot Mower to protect the battery. Store the Robot
Mower, docking station and AC adapter and cords in a dry frost free
area. Cover the ends of the boundary wire with electrical tape. To help
preserve the life of the battery, check the charge status of the battery
and recharge the battery in the docking station at regular intervals.
