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
should be encircled by the boundary line. The boundary wire
line needs to be laid out in a continuous line (see Figure 1).
Route the boundary line around objects using a minimum of
100° angles (135° angles are recommended). Keep the line at
least 12” from the lawn’s edge and from any object (see Figure
1). Keep the boundary line at least 6.5 feet (78”) wide at the
narrowest part of the lawn. Do not allow the boundary wire to
cross itself.
The boundary line should be placed at the root level of the grass
(see Figure 2). Secure the boundary line into the ground and
anchor with the boundary stakes. Place a stake approximately
every 3 feet.
NOTE: The Robot Mower will nd it difcult to work on grades
greater than 30°. On slopes steeper than 30° the robot’s sensor
will shut the mower off.

Docking Station Installation
The docking station must be placed on a solid, at surface.
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
Strip 1/4” of plastic coating from either end of the boundary wire to
ensure a good connection. Remove the terminal cover on the back
of the docking station. Insert the boundary line ends into the docking
station (see Figure 4). Route the “IN” end of the boundary line beneath
the docking station and secure within the plastic brackets on the bottom
of the dock. Place the “IN” wire into the red terminal. After laying and
securing the boundary line, place the “OUT” end of the boundary wire
into the black terminal (see Figure 4). Secure the docking station to the
ground with four long ground stakes provided.

Testing the Docking Station
Charging The Robot Mower
1. Attach the AC adapter cord to the AC adapter.
2. Attach the docking station connection cord to the AC adapter
and to the docking station.
3. Place the Robot Mower in the docking station for charging
ensuring that the contacts on the Robot Mower engage the
charging arms on the docking station on both sides.
Testing the Docking Station
1. Plug the adapter into an AC power outlet. The green LED
should light up.
2. Disconnect the boundary wire from the red terminal and the
green LED should blink and an alarm sounds.
3. Reconnect the boundary line into the red terminal and the
green LED lights continually which indicates that the dock is
connected correctly and ready to charge the Robot Mower.
4. Place the Robot Mower into the docking station making sure
the front of the mower is in contact with the charging arms
on the dock. Allow the mower to charge for 2 - 3 hours before
use.
Preparation for Use
1. Remove all obstacles is the mowing area before starting the
Robot Mower.
2. If the grass is taller than 2-3/8”high (60mm) it is recommended
that you mow the lawn rst with a traditional lawn mower or
set the Robot Mower at its highest cutting position.
Notes on Operation
1. The Robot Mower will sense the presence of rain and return
to the docking station following a course along the boundary
line.
2. The Robot Mower will sense a battery power decline when
there is 20% or less capacity and will automatically return to
the docking station to recharge its battery.
3. Low temperature may effect the operating time.
4. Bumper sensors on the robot mower will cause it to change
direction when it encounters an obstacle.
5. Blades stop rotating in 3 seconds when the mower senses an
incline greater than 30°, the mower is lifted or in the presence
of rain.

Operation
Mowing
1. Lift the rear cover on top of the mower and adjust the cutting height
with the height adjustment dial. Close the cover before starting.
2. Lift the front cover to access the control panel and insert the security
key into the security key slot (see Figure 5). Close the cover.
3. Insert the security key and press the Power Switch to turn mower on.
4. Select the mow area size by pressing one of the three area buttons.
1/16 acre (~2,750 ft2)requires 4 hours operating time,
1/8 acre (~5,500 ft2) requires 8 hours operating time, or
1/4 acre (~11,000 ft2) requires 12 hours operating time.
5. Press the Start button. The timer begins when the Start button is
depressed. The cutting cycle will repeat in 24 hour intervals. Remove
the security key after starting to prevent any alterations in the
programmed cycle. The Robot Mower will start by cutting along the
boundary wire.
6. The second time the robot runs from the docking station, it will mow
randomly in straight lines until there is 20% left of the battery, then
return to the docking station to recharge. After one hour of charging
the robot will resume cutting until working a total number of hours
corresponding to the size of lawn selected. Then it returns to the
docking station to wait for the next timed cycle.
NOTE: You can stop the Robot Mower at any time by pressing the red
STOP bar on top of the mower (see Figure 6). Press the HOME button to
send the robot mower back to the charging station.
7. To restart the Robot Mower after it has automatically shut down the
mower must be within 6-1/2 feet of the boundary wire and you must
reselect the mow area size and press the Start button. If the robot is
restarted when in the docking station a new timing cycle will begin.

Sensors
Obstacle/Contact Sensor
When the Robot Mower meets an obstacle, it will reverse and
change direction to avoid the obstacle. If it does not nd a new
path within 3 seconds, the cutting motor stops. If it does not nd
a new path within 10 seconds, the robot will shut down and it
will require a manual restart to start again.
Rain Sensor
In case of heavy rain, the Robot Mower will automatically return
to the docking station. It will automatically start working the
next day at the time originally started.
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.

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.
Blades are extremely sharp and will cut even when dull.
Use caution when replacing.
Wear gloves to protect hands from cuts.
Battery Replacement
The Robot Mower battery can be accessed by removing the four
retaining screws on the battery compartment cover on the bottom of
the Robot mower (see Figure 9). Always replace with a manufacturer’s
authorized replacement.
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
