2. PRESENTATION
2.2 Function
Capacity
R40Li is recommended for lawns up to 400 m 2 in size.
How big an area R40Li 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 lawns,
R40Li can mow more per hour than if the garden
consists of several small lawns separated by trees,
flower beds and passages.
A fully charged R40Li mows for 30 to 70 minutes,
depending on the age of the battery and how thick the
grass is. Then the mower will charge for approx. 80 to
100 minutes. The charging time can vary depending
on, among other factors, the ambient temperature.
Mowing technique
The mowing system used by R40Li is based on an
effective and energy efficient principle. Unlike normal
robotic lawn mowers, R40Li cuts the grass instead of
striking it off.
We recommend you allow R40Li to mainly mow in dry
weather to obtain the best possible result. R40Li can
even mow in the rain, however, wet grass easily
collects on the mower and the risk of slipping on
steep slopes is greater.
If there is risk for thunder, the transformer should be
disconnected from the power and the boundary wire
and the guide wire from the charging station.
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.
Replace the blades regularly for the best mowing
result. It is very easy to replace the blades. See
