MAINTENANCE

Replacing the blades

STOP

The cutting disc is bolted to the cutting motor shaft and carries three blades that are thrown outwards by centrifugal force when the disc rotates. The blades are each held in the blade disc by their own special screw.

To replace a blade:

1.Rotate the protective plate so that its holes are lined up with the screws.

2.Insert a standard or crosshead screwdriver through the hole and undo the screw.

3.Remove the blade.

The design of the blade holders ensures that they will not come off if they hit small objects such as twigs lying on the lawn.

Check that the blades are not damaged, as this can cause vibration that may damage the Auto Mower. If one or more blades is damaged, replace all three blades at the same time, to keep the cutting disc balanced.

Battery

The service life of the battery depends on the number of hours that the Auto Mower works each day. At five hours mowing a day, the battery will normally last two to three years. The longer the daily mowing period, the shorter the battery life.

If the Auto Mower has been able to find the charging station without difficulty for quite a long time, but then suddenly stops and signals “Cannot find charging station” (3 beeps per second, LED 5 flashing), this may be a sign that the battery needs replacing. Contact your local dealer to check the condition of the battery.

Winter storage

STOP

During the winter the Auto Mower should be stored in a dry place, preferably in its original packaging or parked on all four wheels with the power switch set to “STOP”.

The battery does not require any maintenance over winter.

The charging station should be covered during the winter to protect it from dampness, a tarpaulin or plastic bag are suitable. The transformer should then be disconnected from the mains supply and the six cables disconnected from the lower section. If the charging station is taken indoors the ends of the wires must be protected from dampness by inserting them in Husqvarna’s waterproof connectors. If this is not done the wires will become oxidised, which will lead to contact problems and operating problems with the mower. A black oxidised conductor does not give satisfactory electrical contact.

Resetting the transformer fuse

The mains voltage should be switched off for 10 seconds and then switched on again to reset a tripped fuse.

Cleaning

NOTE!

Never use a high pressure washer, or even running water, to clean the Auto Mower, as water can get into the electronics and destroy sensitive components.

Body, outside

STOP

Use a sponge or soft cloth and water to clean the mower body. If it is very dirty a soap solution or washing-up liquid may be used.

NOTE!

Never use solvents such as acetone, petrol or similar chemicals to clean the mower body.

Underbody and cutting disc

STOP

Inspect the cutting disc and blades once a week. Check that the cutting disc can rotate freely and easily. Also check that the protective plate can rotate freely and easily relative to the cutting disc. Use a brush to remove any clumps of grass or foreign objects and clean the blades if necessary.

Charging pins and contact plates

STOP

If the Auto Mower’s charging pins have black marks this is a sign of poor electrical contact with the contact plates of the charging station. Check that the mower stands on the same level as the charging station and that its charging pins make good contact with the contact plates on the charging station.

Remove corrosion from the Auto Mower charging pins and charging station contact plates if necessary, e.g. after winter storage or if there is a problem with charging. Use a fine abrasive cloth to clean the charging pins and contact plates.

NOTE!

The transformer mains power cable must not be connected when the charging station contact plates are being cleaned. If the transformer is connected and a metal object touches the contact plates they can short- circuit and blow the transformer fuse. There is no risk of harmful electric shock from the 15 V low-voltage supply.

The mains voltage should be switched off for 10 seconds and then switched on again to reset a tripped fuse.
