What's in the box?

Installation of Charging Station:

*The location of charging station must be even, firm and convenient to use the power source. There must be no obstacles or corners within 2 meters in front. First fix the front part of the fence wire under the charging station. And fix the charging station with pegs. The charging stand faces the lawn [inside the fence],and keep it clean. Warning: Cannot install charging station on slope (as shown picture)
*Pull one end of the fence wire out and place it on the lawn floor where the charging station is installed foruse. After the charging station is installed, fix it on it with the fence pegs.
* Leave about 10 centimeters of wire for use at the end of the charging station card slot against the verticalwall (and peel the wire tip), aim the fence wire at the base card slot above the charging station plate and clip the line

Note: The charging station must face the anticlockwise direction of the fence line. The charging station is forbidden to be put on any inclined surface.

2．Installation of Fence Line:
A）The fence line starts under the charging station, wiring in the anticlockwise direction along the lawn edge. It ends at the back side of the charging station. DON’T BURY THE FENCE LINE UNDERGROUND MORE THAN 2CM, THE SIGNAL WILL BE INFLUENCED OTHERWISE.
B）The fence line must pass through the middle of the charging station, and forward at least 2 meters (A).
C）The slimmest distance of wirings must be at least 1.5 meters interval. (B).
D）The fence line corner must have an inner angle of at least 125 o.
E）When there is a fixing facility or flower and tree in the lawn, isolate it as semi-ring-like island or ring-like island with the fence line to avoid any hit

F）Except the front 2 meters of the fence line from the charging station, the distance of the rest fence line to the lawn edge is not less than 30cm.

G) Fix the fence line tightly against the ground with the provided pegs. It is recommended that the pegs are inserted every 1
meter. The pegs can be put even closer each other if the ground elevation differs greatly.
DON’T BURY THE FENCE LINE UNDERGROUND MORE THAN 2CM, THE SIGNAL WILL BE INFLUENCED OTHERWISE.
H) After all the fence line is fixed, reserve 10-15cm terminals respectively for bothfront and tail ends. Strip the terminals to
reveal the copper lines for 2-3cm (Fig. A). Remove the nuts, fasten the copper lines on copper conductors. Then tighten the nuts (Fig.B). Front tail connects with the red pole, rear tail connect with the black pole. When the charger is connected to the charging station and the fence line starts to operate, the red lamp should be off

Note: Do not fold or repeat wiring with the rest fence line. Cut it instead (Fig. C)
Mowing Height:
The mowing height can be adjusted from 2.5cm to 5.5cm by adjusting knob beside the display panel.

Note : Make sure that the power is off before operation.
To protect the charging station from hitting by the mower, please put the fence line like below:

Please note:
a) The starting point should be selected in such a way that it is located in the center of the sub-area to be mowed.
b) The minimum distance between two boundary wires should be more than 100 cm.
c) The sub-area function divides the mowing areas in up to three different sub-areas.
However, this does not mean that the mower mows only within the sub-area. It can also switch to and from between the individual areas.
d) If battery is weak during the sub-area function, and the mower returns automatically to the charging station, after completing the charging operation, it returns from there to the place where it had stopped earlier.
However, if the mower was stopped due to some other problem, it continues its work after the charging operation but not according to the settings. It begins again with the next day specified from the first starting point to the third starting point. – Put the mower in front of the charging station, turn it on, leave it there.

Note: The maximum work time is limited to 255 min. With a net work time of 255 min. charging time is not included.
Troubleshooting:
NOTE: For any fault of the machine, please always check the charging station first, to see if it is under proper working status(fence line is not loosen, or bite by your pets, or cut by the blades of the machine, or your AC power shut down when the machine is working). The lamp on the charging station will be red flashing if there’s such problem.

1. The mower does not start.
a) The mower starts in an ineffective fence line area. Check the fence line for repair.
b) Check the emergency stop switch. If the emergency stop switch is locked, press the emergency stop switch then press red power switch.
c) If the mower has not been used for a long while, the battery may be empty. Make sure to charge it again after charging. Even when unused, it isrecommended that the battery is charged every 3 months.
2. The mower does not move forward.
a) The bumper sensor may be damaged.
b) If the grass is very long(more than 12cm) at the first time, which will shelter the sensor tube, please mow the grass with a traditional lawn mower before using the robot mower.
3. The mower does not mow properly or at all.
a) Turn off the mower. Check if the blades are properly installed. Replace the blades if damaged.
b) If the mower is in a slope which has an angle more than 25 o, the mower will automatically stop.
c). The root part of the blade holder is stuck by objects or grass. Remove them and restart.
d) The grass is too dense to be mowed due to the automatic protection of machine.
e) the machine stopped automatically to protect the PCBs and other components when it tested the motor temperature is too high.

4. The mower crosses the fence line and continues outside the perimeter.
a)The fence line turn angle is too steep. The inner angle must be at least 125 o.
b) The fence line is too close to a slope. Adjust the fence line position to be in accordance to the recommendations.
c) The fence line signal is weak. The fence line must not exceed 200m. If you bury the fence line into the soil, make sure it’s no deeper than 2cm.
d) Check if there are any high-power appliance(such as transformer, generator,telecommunications tower, etc.) nearby. Those appliances could
interfere the machine signer.
5. The battery is not charging, or the mower does not charge properly, it bumps the charge station again and again.
a) The extruding poles of the charger are not in contact with the paddles of the charging station.
b) The extruding poles or the paddles are dirty. Clean them. (Make sure to disconnect the power before cleaning.)
c) If long time no charge, the left power will be exhausted by itself. If the battery broken a little you can re-charge many times to active the battery or you can change the battery.
d) The sensor of the machines is damaged.
6. The mower does not return to the charging station for charging.
a) The fence line is too long. The battery lever is not enough to return the mower to the charging station. Turn off the mower and carry it to the station.
b) If the mower was stopped by obstacle it will stop working
7. Subarea function is failure.
Every working area need to set working time.
8. The island can not work.
The island should be circle，not square。
9. The mower makes a circle in the island and never go to the working area.
The mower will go around about 3 circles, or about 120 seconds, depends on the size of the circle. Then go into the working area.
