  If your Yard force Lawn Mower is making unusual noises, there are several potential causes. First, check the blade fixing screws to make sure they are tightened. If they are loose, tighten them. Second, inspect the blades for any signs of damage and replace them if necessary. Also, the grass may be too high. Try increasing the cutting height, or mow the lawn with an ordinary lawnmower first.

  If your Yard force Lawn Mower is running in circles, several factors could be the cause. Ensure that no power cable runs parallel and close to the boundary wire; if it does, reposition the boundary wire. Check if a front wheel is stuck. If a neighbor has a similar Robotic Mower, try setting your docking station and Robotic Mower to the alternative boundary signal.

  If your Yard force Lawn Mower remains at or returns to the docking station when you press the START button, it could be due to a couple of reasons. Check if the mower has already completed its programmed working time for the day. Alternatively, the battery might be low, so allow the Robotic Mower time to charge and then try again.
