Charging station
The charging station has two tasks. It charges the Auto Mower's
battery when necessary, and also sends control signals along the
search wire and boundary wires. The charging station is connected
to a wall socket via the supplied cable and transformer.

Loop wires

Two separate loop wires have to be laid out, a boundary wire
and a search wire. The boundary wire runs round the edge of
the Auto Mower's working area, and the search wire guides the
Auto Mower to the charging station. Signals transmitted from
these two wires are received by the Auto Mower's sensor.

Auto Mower

Operating principle
The Auto Mower mows your lawn automatically. When its
battery runs down it moves to its charging station to recharge.
When the battery is fully charged, the Auto Mower starts
mowing again.
The Auto Mower is controlled by a built-in computer that
consists of a circuit board with a microprocessor. The computer
is the Auto Mower's "brain" and handles all of its functions,
commands and path selection by means of the data gathered
via the keypad, sensor and battery charging status.
Movement pattern
The Auto Mower always starts
its work in accordance with the
random principle, i.e. the
starting path is unplanned.
Each time it hits an obstacle or
senses the signal from the
boundary wire, the computer
chooses a new direction. This is
designed so that the Auto
Mower never regularly repeats
the same movement pattern.
If the Auto Mower enters an
area where it senses that the
grass is longer than where it
has just been, it can start to
mow systematically. It then
mows in a spiral pattern,
mowing the area that has
longer grass than the sur-
rounding area. After this it
returns to the random principle.
Initially the Auto Mower works for a few hours to get an idea of
the average length and thickness of the grass. Only then does it
start working systematically.
When the front of the Auto Mower bumps into an obstacle it
backs away and chooses a new direction.
When the Auto Mower needs to charge its battery it follows the
search wire that leads it to the charging station. If the battery
doesn't need charging the Auto Mower ignores the search wire.
Working capacity
The Auto Mower can cut about 100 m
operating and is recommended for grass areas of up to approx.
1650 m 2 /18 000 ft 2 ± 20%.
The size of the area that the Auto Mower can mow depends
partly on the shape of the garden. If the working area consists
of an open lawn, this generally means that the Auto Mower can
mow a larger area than if the working area consists of several
grass areas or one that has many trees, flower beds or the like.
The length of time the Auto Mower spends mowing and re-
charging can vary, and depends partly on the temperature.
