Noises from various places in the robot. What should I do?

This article contains the following sections:

 

 

 

For RC, TC, MC models

Q1 . Turn the System Switch to Off, lift the robot from its front area and check if there is any visible reason causing the loud sound.

Possible reasons are:

  • Debris stuck in the mowing deck
  • Bent blade
  • Mulches built up between mowing deck and blades
  • Rotate the blade (using long stick, or gloves). See the image to the right.

Were any of the above reasons found with the robot?

If Yes – Clean / Remove / Replace the object that caused the noises.

If No - Proceed to Q2.

 

 

Q2 . Turn both drive wheels manually. Can loud noises be heard from one of them compared to the other wheel?

If Yes – Replace the Gear case.

If No – Proceed to Q3.

 

 

Q3 . Rotate the Front Wheel on its axle and against the robot’s chassis.

Can it turn and rotate freely?

(Do it with the Front Wheel in its inner position and not its outer position, like when the robot is on the ground).

If Yes – Proceed to 4.

If No – Try to release the wheel (debris or mulches that are preventing the wheel from rotating freely).
If this cannot be released, the robot needs to be taken to an Authorized Service Station for repair.

 

 

Q4 . Place the robot inside the lawn and send it back to base by pressing the 'Home' button (the Mow motor is not working). Can loud noises be heard from the robot?

If Yes – Create a short video (via your smart Phone, or a digital camera), and send it to the Hotline agent that answered your call or sent an email to you with this information.

If No – Proceed to Q5.

 

Q5 . Send the robot to mow by pressing the 'Scan' buttom (Mow motor is working). Can loud noises be heard from the robot?

If Yes – Remove the blade (watch the video), then send the robot to mow again. Proceed to Q6.

If No – Let the robot complete the next few operations to understand if the problem was sporadic or recurrent.

 

Q6 . Were the loud noises reduced?

If Yes – Replace the blade and run the robot to observe if the noises are gone. If the noises are still heard, replace the Mow Motor.

If No – The robot needs to be taken for repair to an Authorized Service Station.
