QUICK GUIDE

1. PLACEMENT OF AND CONNECTING THE CHARGING STATION

See chapters 3.2 and 3.3 in the Operator’s Manual

Place the charging station at a central position in the working area, with a lot of open space in front of the charging station and on a relatively horizontal surface.
Connect the power supply’s low voltage cable to the charging station and the power supply.
Connect the power supply to a 100-240 V wall socket.
Place the robotic lawnmower in the charging station to charge the battery while the boundary wire is laid. Set the main switch to position 1.

2. PLACEMENT OF THE BOUNDARY WIRE AND THE GUIDE WIRE

See chapter 3.4 in the Operator’s Manual

Lay the boundary wire so that it forms a loop around the working area.
Make an eyelet at the point where the guide wire will later be connected.
Run the guide wire to the point on the boundary loop where the connection will be made. Avoid laying the wire at tight angles.

3. CONNECTING THE BOUNDARY WIRE AND THE GUIDE WIRE

See chapter 3.5 in the Operator’s Manual

Narrow passages in the garden make it difficult for the robotic lawnmower to find the charging station. The robotic lawnmower can be lead to remote garden areas using the guide wire. The guide wire also helps the robotic lawnmower to quickly find the charging station.
Lay the guide wire under the charging station and at least 2 m / 6.5 ft straight out from the front edge of the charging station.
Open the connectors and lay the wire ends in the recesses on each connector.
Press the connectors together using a pair of pliers.
Cut off any surplus boundary wire. Cut 1-2 cm / 0.4-0.8 ” above the connectors.
Press the connectors onto the contact pins, marked AL (left) and AR (right), on the charging station. It is important that the right-hand wire is connected to the right-hand contact pin, and the left-hand wire to the left-hand pin.
Fasten the connector to the contact pin marked G1 on the charging station.

4. CONNECTING THE GUIDE WIRE TO THE BOUNDARY WIRE

See chapter 3.6 in the Operator’s Manual

Cut the boundary wire with a wire cutters at the centre of the eyelet that was made in step
2. 2. Connect the guide wire to the boundary wire using the accompanying couplers. Press the couplers completely together witha pair of pliers.

5. STARTING AND STOPPING

See chapters 4.3 and 4.4 in the Operator’s ManualSTARTING

Open the cover by pressing the STOP button.
Set the main switch to position 1. When you do this for the first time, a start up sequence starts where you select a four digit PIN code among other things.
Press the START button and close the cover.STOPPING Press the STOP button.

6. ADJUSTING THE ROBOTIC LAWNMOWER TO SUIT THE SIZE OF YOUR LAWN

See chapter 6.3 in the Operator’s ManualThe mowing results depend on mowing time. Adjust the mowing time to suit your garden using the Timer function. You decide what times during the day the robotic lawnmower is to work. The robotic lawnmower cuts approximately 90 m² / 0.022 acre per hour and day for Automower® 420, 135 m² / 0.033 acre for Automower® 430X, 167 m² / 0.041 acre for Automower® 440 and 210 m² / 0.052 acre for Automower® 450X. For example, if your garden comprises 1200 m² / 0.3 acre of grass, the mower should work 13 hours a day for Automower® 420, 9 hours a day for Automower® 430X, 7 hours a day for Automower® 440 and 6 hours a day for Automower® 450X.

7. MAINTENANCE

See chapter 8 in the Operator’s Manual

The main switch should be in the 0 position during all work on the robotic lawnmower’s chassis, such as cleaning or replacing the blades. Replace the blades regularly for the best mowing result.
Never use a high-pressure washer or even running water to clean the robotic lawnmower. Never use solvents for cleaning.
All connections to the charging station (power supply, boundary and guide wire) must be disconnected if there is a risk of a thunderstorm.
Fully charge the battery at the end of the season before winter storage.
