OPERATION
2. Spiral Cutting
In Spiral cutting mode, the robotic mower will mow in a spiral outwards from where it is placed on the
lawn. This is best used to tidy up any areas that may not have been mowed during a random mowing
session.
After the robotic mower is powered on, press the Spiral button for 1 second followed by the START/ON
button. The mower will first move forward about 3.94'' (10 cm) to 7.87'' (20 cm), then start Spiral cutting
covering approximately 21.53 sq. ft (2 m
mow in a random pattern automatically.
If the area to be mowed is too narrow for the robotic mower to carry out the spiral cut, after continuous
searching, the mower will mow in a random pattern automatically.
NOTE: Spiral cutting is also a great feature to use before random mowing to systematically and
efficiently cut the main areas of the lawn, by doing this it reduces the amount of random cutting time
needed to complete the lawn. You also get a better lawn finish.
SETTING THE CUTTING HEIGHT
WARNING
Do not make any adjustment to the robotic mower without first stopping the motor. Keep your feet
away from the blade disc when adjusting its height.
The cutting height of the mower can be adjusted from MIN 1'' (25 mm) to MAX 2.5'' (65 mm) (Fig. 19).
During the first weeks of mowing, always select the higher cutting height 1.5'' (40 mm). After this, the
cutting height can be lowered step by step every week until the desired cutting height has been reached.
1. Press the STOP button to stop the robotic mower.
2. Turn the cutting height adjustment knob to set the cutting height.
- Turn clockwise to raise the cutting height.
- Turn counter clockwise to lower the cutting height.
3. For the first cut each season, a higher cutting setting should be selected. USING A CUTTING
HEIGHT THAT IS TOO LOW IN LONGER GRASS WILL USE MORE POWER AND REDUCE
BATTERY RUN TIME.
4. Before you begin to mow, check to ensure that the blade is not blunt and that none of the fasteners
are damaged. To prevent any imbalance, replace blunt and/or damaged blades. To carry out this
check, first switch off the mower by removing the safety key.
