7 Maintenance and
service

7.1 Cleaning

Clean the body, display cover and chassis regu-
larly. The best way to clean the body is with a
damp sponge or cloth. The underside of the body,
wheels and blade disc are best cleaned with a
brush (for example, a washing-up brush). A spray
bottle with water and a small amount of washing-
up liquid can help to remove dried dirt and grass.
Disassemble the body to clean the body, display
cover and chassis more meticulously.
NB!
Never use a high pressure washer or even
running water.
The main switch should be in the 0 position. Wear
gloves when cleaning the underside of the body.
It is important to clean off any grass and dirt be-
tween the chassis and the blade disc as well as
between the blade disc and the blades. Disas-
semble the blade disc to enable more thorough
cleaning. Run the blade motor using the Tools -
Test - Motors- Blade motor test function. Listen
for abnormal sounds when the blade motor is run-
ning. Also test with various cutting height settings.

7.2 Winter storage

Before the robotic lawnmower is put away for the
winter, the following should be done:
• Clean the entire mower thoroughly.
• Remove the blade disc and clean around
the blades so that they can be freely
rotated and also around the motor shaft.
• Disassemble the drive wheels and
remove grass and other objects from the
motor shafts. Clean the wheels' drive
tread. Fit the wheels again.
• Set the main switch in 0 position.
• Fully charge the mower. However, the
mower must not be left in the charging
station during the entire winter storage
period.
IMPORTANT INFORMATION
Charge the battery fully before winter
storage.
