Maintenance and care
9.2
Regular checks
General checks
1. Once a week, check the whole Installation for
damage:
■
Machine
■
Base station
■
Boundary cable
■
Low voltage cable
■
Transformer with power cable
2. Replace defective parts by original spare
parts from AL-KO or have them replaced by
an AL-KO service centre.
Check the rollers can move freely
Once a week, carry out the following:
1. Carefully remove grass residues and soiling
from the areas around the rollers. Use a
broom and cloth for this.
2. Check that the rollers run freely and that they
can be steered.
Note: If the rollers do not move freely or can-
not be steered, have them replaced by an
AL-KO service centre.
Check the contact surfaces on the automatic
lawn mower
1. Use a cloth to remove soiling and then lightly
grease with contact grease.
2. Rub any charring on the contact surfaces
down to the bare metal surface with fine sand
paper and then lightly grease with contact
grease.
Check the charging contacts of the base
station
1. Disconnect the mains plug.
2. Press the charging contacts in the direction
of the base station and release them. The
charging contacts must spring back into the
initial position.
Note: If the charging contacts do not spring
back, have them replaced by the AL-KO ser-
vice centre.

457293_a
IMPORTANT!
Damage to the appliance due to incor-
rect repair
The blade plate can be damaged by the
alignment of a bent, built-in cutting blade.
■
Do not align bent cutting blades.
■
Replace bent cutting blades by ori-
ginal spare parts from AL-KO.
CAUTION!
Danger of injury due to the cutting
blade
The cutting blades are very sharp and
can cause cutting injuries.
■
Wear protective gloves.
■
Make sure that parts of the body do
not get into the cutting blade.
1.
Switching off the appliance.
2. Put down the appliance with the cutting
blades pointing upwards.
3. Unscrew the fastening screws with a span-
ner.
4. Pull the cutting blade out of the blade seat.
5. Clean the blade seat with a soft brush.
6. Push in a new cutting blade.
Note: It is only allowed to use original spare
parts from AL-KO.
7. Insert the fastening screws again and firmly
tighten.
As a rule, the clearer blades do not need to be
replaced.
In case of stubborn dirt that cannot be removed
with a brush, the blade plate must be replaced
because an imbalance can lead to increased
noise levels, greater wear and malfunctions.

Replacing the fuse on the
transformer (11)
If the transformer no longer provides any current
although the mains voltage supply is intact:
1. Disconnect the transformer (11/2) from the
mains supply.
2. Unscrew the fuse cover (11/1) including the
fuse from the transformer (11/2).
3. Check the fuse. If defective, insert a new fuse
with the same rating (2.5 A, slow blow).
4. Insert the new fuse in the fuse cover.
5. Screw in the fuse cover including the fuse
into the transformer.
