Replacing The Blades; Battery; Winter Storage; Cleaning - Husqvarna Auto Mower Operator's Manual

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 the Husqvarna storage case. The original
packaging or storing on all four wheels with the power switch
set to "STOP" may be used.
• The battery does not require any maintenance over winter.
• The charging station should be covered during the winter to
protect it from moisture, a tarpaulin or plastic bag are suitable.
If the docking unit is taken indoors for the winter the lower
section must also be taken in. The transformer should then be
disconnected from the receptacle and the six wires discon-
nected from the lower section. The wire ends should then be
protected from moisture by inserting them in the Husqvarna
waterproof connector. If this is not done, the cables will
become oxidized. An oxidized conductor will not give satisfac-
tory electrical connection.
MAINTENANCE

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 mild washing liquid may be
used.
NOTE!
Never use solvents such as acetone, petroleum based
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. Fill in any holes under the rear wheels of the
mower and bend down the contact plates so that they make
good contact with the pins.
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 power cable must not be inserted in the
receptacle 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.
