For more information, see operating instructions or visit the "Products" section of this Website.
Does the charging station have to be placed on the lawn or could it be placed in a garden bed?
The area in front of the charging station is a high-traffic location. The Robotic Lawnmower should be able to start in any directions and return to the charging station from any direction.
For further information, see section "How to install the charging station for the GARDENA Robotic Lawnmower" in the operating instructions.
I have a narrow passage in my garden; will it be a problem for the Robotic Lawnmower?
The narrowest possible passage that the Robotic Lawnmower can manage is 60 centimetres in width (from wall-to-wall). It is better though to avoid long narrow passages and areas narrower than 1.5 metres since there is a risk that the Robotic Lawnmower will travel around in the passage for a period of time making the lawn look flattened.
At what level should I set my mowing levels once installation is complete?
Mowing the grass too low right after the installation can damage the wire insulation. Damage to the insulation may not cause disruptions until several weeks or months later. To avoid this, always select the maximum cutting height during the first weeks after installation and then lower the height one step at a time every second week until the desired cutting height has been reached.
How do I find a break in the wire?
Breaks in the loop wire are usually the result of unintentional physical damage to the wire such as when gardening with a shovel or due to the wire being stretched excessively during installation. It can also be caused by mowing too low right after installation.
It is easy to fix the break once found. The damaged section must simply be replaced with a new wire and connected using original GARDENA couplers. To find the break when the wire is buried, simply follow the comprehensive step-by-step instructions on page 47 of the owner’s manual. Remember to make sure that ECO mode is turned off.
How often do I need to replace the blades?
The blades must be kept in good condition in order to obtain the best mowing results. Although keeping your lawn free of stones, branches and other objects will keep the blades sharp longer, they will need to be changed approximately every 6-12 months depending on usage. When changing blades, it is important to only use GARDENA blades and screws and in order to maintain balance, all three blades must be changed at once.
