Automower runs at an angle or in an arc — Tilt sensor calibration or defect

What does Automower runs at an angle or in an arc mean?

This symptom describes the Automower not driving in a straight line, but rather at an angle or in an arc. This is typically due to an incorrectly calibrated tilt sensor or a defective tilt sensor.

• The tilt sensor is calibrated incorrectly, causing the mower to compensate for a perceived slope.
• The tilt sensor is defective.
• Grass has accumulated on one of the drive wheels, affecting traction.

Click steps to track your progress.

1. 1

   Calibrate the tilt sensor by selecting Tools - Special settings - Calibrate tilt sensor (shortcut 5-6-3).

2. 2

   Check the drive wheels for accumulated grass or debris and clean them.

3. 3

   Use wheel brushes (505 13 27-01) to keep drive wheels clean and improve traction.

4. 4

   If calibration does not resolve the issue or if the tilt sensor is determined to be defective, the control box may need to be replaced (see page 92).

5. 5

   Contact service if the problem persists after calibration and cleaning.
