Maintenance
WARNING
When the robotic lawnmower
is turned upside down the main
switch must always be in the 0
position.
The main switch should be set
in the 0 position during all work
on the mower's chassis, such as
cleaning or replacing the blades.
IMPORTANT INFORMATION
Never use a high-pressure washer or even
running water to clean the robotic lawn-
mower. Never use solvents for cleaning.
Inspect the robotic lawnmower each week and replace
any damaged or worn parts. The following must be carried
out in the weekly inspections:
• Clean the charging station from grass, leaves,
twigs and other objects that may impede the robotic
lawnmower from docking with the charging station.
• Set the main switch to position 0 and put on a pair of
protective gloves. Turn the robotic lawnmower upside
down. Check the following:
1. Clean the drive wheels. Grass in the drive wheels
can impact on how the lawnmower works on
slopes.
2. Clean the front wheels. Grass on the front wheels
and the front wheel axles can affect performance.
3. Clean the body, chassis and cutting system.
Grass, leaves and other objects that weigh down
the product affect performance.
4. Check that all mower blades are intact. Check
also that the blades can pivot freely. Even if the
mower blades are intact, they must be replaced
on a regular basis for the best mowing result and
low energy usage. Replace all blades and screws
at the same time if necessary to keep the rotating
parts balanced see 8.7 Blades on page 78.
