5 Maintenance

5.1 Introduction - maintenance

For better operating reliability and longer service life:

check and clean the robotic lawnmower regularly and

replace worn parts if necessary. All maintenance and

servicing must be done according to GARDENA's

instructions. See 

Guarantee terms on page 52.

When the robotic lawnmower is first used, the blade disc

and blades should be inspected once a week. If the

amount of wear during this period has been low, the

inspection interval can be increased.
It is important that the blade disc rotates easily. The

edges of the blades should not be damaged. The

lifetime of the blades varies immensely and depends for

instance on:

Operating time and size of the working area.

Type of grass and seasonal growth.

Soil, sand and use of fertilizers.

The presence of objects such as cones, windfalls,

toys, tools, stones, roots and the like.

The normal life is 4 to 7 weeks when used under

favorable conditions. See 

Replace the blades on page

37 on how to replace the blades.

WARNING: Wear protective gloves.

Note: Working with blunt blades gives a poorer mowing

result. The grass is not cut cleanly and more energy is

needed resulting in the robotic lawnmower not mowing

such a large area.

5.2 Clean the robotic lawnmower

It is important to keep the robotic lawnmower clean. A

mower with large amounts of grass stuck to it will not

cope as well with slopes. It is recommended to clean

using a brush.

CAUTION: Never use a high-pressure washer

or even running water to clean the robotic

lawnmower. Never use solvents for cleaning.

5.2.1 Chassis and blade disc

1. Set the main switch to position 

0.

2. Lift the robotic lawnmower onto its side.
3. Clean the blade disc and chassis using for example

a dish brush. At the same time, check that the blade

disc rotates freely in relation to the foot guard. Also,

check that the blades are intact and can pivot freely.

If long grass or other objects find their way in, these

may impede the blade disc. Even a slight braking

effect leads to a higher consumption of energy and

at worst will prevent the robotic lawnmower from

being able to mow a large lawn.

5.2.2 Chassis

Clean the underside of the chassis. Brush or wipe with a

damp cloth.

5.2.3 Wheels

Clean around the front wheels and rear wheel as well as

the rear wheel bracket. Grass on the wheels can impact

on how the lawnmower works in slopes.

5.2.4 Body

Use a damp, soft sponge or cloth to clean the body. If

the body is very dirty it may be necessary to use a soap

solution or washing-up liquid.

5.2.5 Charging station

Clean the charging station regularly from grass, leaves,

twigs and other objects that may impede docking.

5.3 Replace the blades

WARNING: Always use blades and screws of

the right type. GARDENA can only guarantee

safety when using original blades. Only

replacing the blades and reusing the screw can

result in a screw wearing during mowing and

shearing. The blades can then be propelled

from under the body and cause serious injury.

Replace worn or damaged parts for safety reasons.

Even if the blades are intact, they should be replaced on

a regular basis for the best mowing result and low

energy usage.
There are 3 blades on the robotic lawnmower, which are

screwed into the blade disc. All 3 blades and screws

must be replaced at the same time to obtain a balanced

cutting system.
Use GARDENA original blades embossed with the

crowned H-mark logotype, see 

Warranty on page 52.
