1.5 Cutting technique
The mowing system is based on an efficient and en -
ergy saving principle. Unlike many conventional mow-
ers, the robotic lawnmower cuts the grass instead of
knocking it off.
1.5.1 Mowing in different weather
conditions
Rain
We recommend you allow the robotic lawnmower to
mainly mow in dry weather to obtain the best possible
result. The robotic lawnmower can also mow in the
rain, however, wet grass easily sticks on the robotic
lawnmower and there is a greater risk of it slipping on
steep slopes.
Thunder
If there is a risk of thunder, all connections to the
charging station must be disconnected. This is done
to avoid damage to the circuit board in the charging
station.
1.5.2 Blades
It is more important to have good condition and sharp
blades on a robotic lawnmower than on a conven-
tional mower. It is the principle of the cutting the grass
instead of knocking it off that makes this difference.
The double edged blades together with the technol-
ogy that rotates the blade disc in both directions in-
crease the life of the blades.
In order to keep the blades sharp for as long as pos-
sible it is important to keep the lawn free from branch-
es, small stones and other objects.
Worn blades should not be ground. This is to prevent
the mowing system from becoming imbalanced.
Poor or dull blades can result in the grass bending
instead of being mown, the tops become frayed and
the mower may find it difficult to mow a large working
area.
All blades and screws must be replaced at the same
time to ensure the cutting system is balanced.
There are many different types of blades and they
are sold in various package sizes. Use only approved
original blades from Husqvarna. From the start of
2011 these are marked with a Husqvarna symbol.
