5.7 Replacing the battery
1. Dismantle the body, see
5.2.1 Dismantling
the body on page 59
.
2. Dismantle the chassis, see
5.2.2 Dismantling the chassis on page 59
.
3. Loosen the 3 screws (Torx 20) retaining the
battery holder.
4. Disconnect the battery connection from the
main circuit board.
5. Dismantle the battery holder and remove
the battery.
6. Fit a new original battery from Husqvarna
and connect it to the main circuit board.
7. Assemble the mower in the reverse order

5.8 Replacing the MCB
1. A mower’s operating information is stored
in the control box. The Autocheck EXP
service program saves this information
in the log book and then transfers it back
to the mower again when the main circuit
board has been replaced. The mower must
therefore be connected to Autocheck EXP
before replacing the main circuit board. The
operating data is then saved automatically.
2. Dismantle the body, see
5.2.1 Dismantling
the body on page 59
.
3. Dismantle the chassis, see
5.2.2 Dismantling the chassis on page 59
.
4. Disconnect all cables from the main circuit
board. Always pull the connector and NOT
the cable. Note the connector to which the
cables are fitted so that the right cable is in
the right position when reassembling. The
main circuit board is also labeled to show
which function each connector has.
5. Unscrew the 2 screws (Torx 20) that secure
the main circuit board to the chassis’ lower
section.
6. Remove the old main circuit board. If the
board is to be checked in order to evaluate
the guarantee it should be stored in a bag
with protection against ESD (electrostatic
discharge).
7. Fit the new main circuit board and holders.
8. Connect all connectors to the main circuit
board. Check that the cables are connected
to the correct place.
9. Fit the chassis and body.
