How big an area the robotic lawnmower can keep cut depends primarily
on the condition of the blades and the type, growth and moisture of the
grass. The shape of the garden is also significant. If the garden mainly
consists of open lawn areas, the robotic lawnmower can mow more per
hour than if the garden consists of several small lawns separated by
trees, flower beds and passages.
A fully charged robotic lawnmower mows for 40 to 170 minutes, depen-
ding on model, the age of the battery and how thick the grass is. Then
the robotic lawnmower will charge for 50 to 90 minutes. The charging
time can vary depending on, among other factors, the ambient tempera-
ture.
Mowing technique
The cutting system in the Husqvarna robotic lawnmower is based on an
efficient and energy saving principle. Unlike many standard lawnmo-
wers, the robotic lawnmower cuts the grass instead of knocking it off.
We recommend you allow the robotic lawnmower to mainly mow in dry
weather to obtain the best possible result. Husqvarna's robotic lawnmo-
wers can also mow in the rain, however, wet grass easily sticks on the
robotic lawnmower and there is a greater risk of slipping on steep slo-
pes.
The blades must be in good condition to obtain the best mowing result.
In order to keep the blades sharp for as long as possible it is important
to keep the lawn free from branches, small stones and other objects
which can damage the blades. Replace the blades regularly. For infor-
mation on replacing the blades, see the complete Operator's Manual on
the attached DVD.
Working method
The robotic lawnmower automatically mows the lawn. It continuously
alternates between mowing and charging.
The robotic lawnmower starts to search for the charging station when
the battery charge becomes too low. The robotic lawnmower does not
mow when it is searching for the charging station.
When the battery is fully charged, the robotic lawnmower will leave the
charging station and start mowing in a place in the garden where it has
not been lately. The place is decided by the built-in GPS-receiver. This
function is for Automower 330X only. For the other models you might
®
have to set manual exit settings to make sure that the lawn will be cut
evenly, see chapter 6 Menu functions in the complete Operator's Manual
on the attached DVD.
When the robotic lawnmower body hits an obstacle, the robotic lawnmo-
wer reverses and selects a new direction.
Sensors at the front and back will sense when the robotic lawnmower is
approaching the boundary wire. The robotic lawnmower travels up to 28
centimeters beyond the wire for Automower
metres beyond the wire for Automower
around.

The STOP button on the top of the robotic lawnmower is mainly used to
stop the robotic lawnmower when it's running. When the STOP button is
pressed a hatch opens, behind which there is a control panel. The STOP
button remains pressed in until the hatch is closed again. This together
with the START button acts as a start inhibitor.
The control panel on the top of the robotic lawnmower is where you
manage all the robotic lawnmower settings.

When the main switch is set to 1 for the first time, a start-up sequence
begins which includes a number of important basic settings, see 3.8 First
start-up and calibration in the complete Operator's Manual on the
attached DVD.
Movement pattern
The movement pattern of the robotic lawnmower is random and is deter-
mined by the robotic lawnmower itself. A movement pattern is never
repeated. With this cutting system the lawn is mown very evenly without
any mowing lines from the robotic lawnmower.
Finding the charging station
The Automower 320/330X can be set to search for the charging station
®
in one or more of three different ways. The robotic lawnmower automati-
cally combines these three search methods to locate the charging sta-
tion as fast as possible but also to avoid as much tracks forming as pos-
sible. Automower 305/308 always follows the guide wire to the charging
®
station.

2.3 Adjusting the cutting height

If the grass is long, allow the robotic lawnmower to start mowing at the
MAX cutting height. Once the grass is shorter, you can gradually lower
the cutting height.
IMPORTANT INFORMATION
During the first week after a new installation, the cutting
height must be set to MAX to avoid damaging the loop wire.
After this, the cutting height can be lowered one step every
week until the desired cutting height has been reached.
