5 Maintenance
5.1 Introduction — maintenance
For better operating reliability and longer service
life: check and clean the product regularly and
replace worn parts if necessary. All maintenance
and servicing must be done according to
GARDENA’s instructions. Refer to Guarantee
terms on page 52.
When the product 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 work 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. Refer to To replace the
blades on page 34 on how to replace the
blades.
Note: Working with blunt blades gives a poorer
mowing result. The grass is not cut cleanly and
more energy is needed resulting in the product
not mowing such a large area.
WARNING: The product must be
turned off before any maintenance is
done. The product is disabled when
the indicator lamp on the ON/OFF
button is not lit.
WARNING: Wear protective gloves.
5.2 Clean the product
It is important to keep the product clean. A
product with large amounts of grass stuck to it
will not cope as well with slopes. It is
recommended to clean using a brush.
GARDENA offers a special cleaning and
maintenance kit as an accessory. Contact your
GARDENA central service.
CAUTION: Never use a high-pressure
washer to clean the product. Never
use solvents for cleaning.
5.2.1 Chassis and blade disc
Inspect the blade disc and blades once a week.
1. Press the STOP button.
2. Press the ON/OFF button for 3 seconds to
turn off the product.
3. Check that the indicator lamp on the
ON/OFF button is not lit.
4. If the product is very dirty, clean it by using a
dish brush or a garden hose. Do not use a
high-pressure washer.
5. Lift the product onto its side.
6. 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.
5.2.2 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 product performs
in slopes.
5.2.3 Cover
Use a damp, soft sponge or cloth to clean the
cover. If the cover is very dirty it may be
necessary to use a soap solution or washing-up
liquid.
953 — 002 — 12.12.2018 Maintenance — 33

Page: 34

5.2.4 Charging station
Clean the charging station regularly from grass,
leaves, twigs and other objects that may impede
docking.
WARNING: Use the plug to disconnect
the charging station before any
maintenance, or cleaning of charging
station or power supply.
5.3 Replace the blades
WARNING: 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. 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. 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, refer to Guarantee
terms on page 52.
5.3.1 To replace the blades
1. Press the STOP button.
2. Open the hatch.
3. Press the ON/OFF button for 3 seconds to
turn off the product.
4. Check that the indicator lamp on the
ON/OFF button is not lit.
5. Turn the product upside down. Place the
product on a soft and clean surface to avoid
scratching the body and the hatch.
6. Remove the 3 screws. Use a straight slot or
cross-tip screwdriver.
7. Remove each blade and screw.
8. Fasten new blades and screws.
9. Check that the blades can pivot freely.
5.4 Software update
If service is done by GARDENA customer service
then available software updates are downloaded
to the product by the service technician.
However, owners of GARDENA products can
update the software if this is initiated by

The shape of the work area requires
the use of Area 1-3 for the product to
find its way to all remote areas.
Use Area 1-3 to steer the product to a
remote area. Refer to To set the Lawn
Coverage function on page 24.
The How often? setting is incorrect in
relation to the layout of the work area.
Check that the correct How often? val-
ue is selected.
Work area too large. Try limiting the work area or extending
the work time. Refer to To set the
schedule on page 23.
Dull blades. Replace all the blades. Refer to To re-
place the blades on page 34.
Long grass in relation to the set cutting
height.
Increase the cutting height and then
successively lower it.
Accumulation of grass by the blade
disc or around the motor shaft.
Check that the blade disc rotates freely
and easily. If not, screw off the blade
disc and remove grass and foreign ob-
jects. Refer to Clean the product on
page 33.
6.6 Find breaks in the loop wire
Breaks in the loop wire are usually the result of
unintentional physical damage to the wire such
as when gardening with a shovel. In countries
with ground frost, also sharp stones that move in
the ground can damage the wire. Breaks can
also occur due to the wire being stretched
excessively during installation.
Mowing the grass too low right after the
installation can damage wire insulation. Damage
to the insulation may not cause disruptions until
several weeks or months later. To avoid this,
always select the maximum cutting height the
first weeks after installation and then lower the
height one step at a time every second week until
the desired cutting height has been reached.
A defective splicing of the loop wire can also lead
to disruptions several weeks after the splice was
done. A faulty splice can, for example, be the
result of the original coupler not being pressed
together hard enough with a pair of pliers, or that
a coupler of lower quality than the original
coupler has been used. Please first check all
known splices before further troubleshooting is
done.

A wire break can be located by gradually halving
the distance of the loop where the break may
have occurred until there is only a very short
section of the wire left.
The following method does not work if ECO
mode is activated. Make sure first that ECO
mode is turned off. Refer to ECO mode on page
26.
1. Check that the indicator lamp in the charging
station flashes blue, which indicates a break
in the boundary loop. Refer to Indicator lamp
in the charging station on page 43.
2. Check that the boundary wire connections to
the charging station are properly connected
and not damaged. Check that the indicator
lamp in the charging station is still flashing
blue.

L
POWER
3. Switch the connections between the guide
wire and the boundary wire in the charging
station.
Start by switching connection L and GUIDE.
If the indicator lamp is lit with a solid green
light, then the break is somewhere on the
boundary wire between L and the point
where the guide wire is connected to the
boundary wire (thick black line in the
illustration).
GUIDE
L
Guide
To rectify the fault you will need boundary
wire, connector(s) and coupler(s):
a) If the suspected boundary wire is short
then it is easiest to exchange all of the
boundary wire between L and the point
where the guide wire is connected to the
boundary wire (thick black line).
b) If the suspected boundary wire is long
(thick black line) then do as follows: Put L
and GUIDE back to their original positions.
Then disconnect R. Connect a new loop
wire to R. Connect the other end of this new
loop wire at the middle of the suspected wire
section.

If the indicator lamp now is green, then the
break is somewhere in the wire between the
disconnected end to the point where the
new wire is connected (thick black line
below). In that case, move the connection
for the new wire closer to the disconnected
end (roughly at the middle of the suspected
wire section) and check again if the indicator
lamp is green.
Continue until only a very short section of
the wire remains which is the difference
between a solid green light and a flashing
blue light. Then follow instruction in step 5
below.
4. If indicator lamp still flashes blue in step 3
above: Put L and GUIDE back in their
original positions. Then switch R and
GUIDE. If indicator lamp now is lit with a
solid green light then disconnect L and
connect a new boundary wire to L. Connect
the other end of this new wire at the middle
of the suspected wire section. Follow the
same approach as in 3a) and 3b) above.
5. When the break is found, the damaged
section must be replaced with a new wire.
Always use original couplers.
