A Screw Loose !?!

Posted By: Mary Maccpherson Times Read: 228

SEE ALSO UPDATE APRIL 2017

As we have received a couple of calls regarding the Litter-Robot no longer turning the globe, but appearing in working order still otherwise, you may have a screw loose (no offence!).

The globe is turned by a black gear wheel that is visible on the right side of the base unit, when the globe is removed. The gear wheel turns, engaging with and turning the ball shape via the knobbly ‘track’ that is part of the outside casing of the globe. If the gear wheel stops turning, or is loose to touch rather than firmly set in place (not able to be rotated by fingers), then it maybe the screw that holds the wheel to the rotating shaft (like an axel on a car wheel), may have come loose and needs to be tightened.  If you do think you may have a screw loose, the following information is very helpful.

If you're experiencing a Litter-Robot with a free or loose spinning gear, and no globe movement, it sounds like the set screw has come loose. Below are the instructions to tighten the set screw. You will need a 3mm allen, hex, wrench. A picture is attached for your reference.

1. Turn off the unit and unplug the power cord. Remove the globe (and bonnet where applicable) and locate the black gear.
2. Locate the shaft attached to the gear, this is where the set screw is located. If you can see the screw, skip to step 5.
3. Turn on the power and watch for the flat side to rotate into the position that enables you access to the set screw. The flat side of the shaft will be facing you.

LR3 USERS: If you own an LR3 (Open Air) the flat of the shaft may be difficult to see. You will also need to place the bonnet back on the base without the globe to engage the motor. When the gear starts to rotate, check to see the screw. When it is visible for access to tighten, press CYCLE to pause the motor. Tighten, the press CYCLE again and let the motor complete the full cycle. Note the lights will flash at the end as the globe is not in place. This covers sets 4 & 5, noting check for step 6. Turn off power, remove bonnet, and re-assemble as normal.

4. Once aligned, turn off the power and unplug the unit.
5. Using a 3 mm hex wrench, tighten the set screw by turning it to the right.
6. Attempt to move the gear with your fingers to assess if the screw is tightened enough. If the gear still moves, repeat step 5.
7. Place the globe (and bonnet where applicable) back on the base, turn the power on, and press the cycle button. If the unit completes the cycle and returns to home with a green light, your problem should be solved.

If the above steps did not solve your problem, please make a note of, or take a mini-video/picture of what light patterns, noises, or behaviours you experience, so that Customer Service can help you further.

   

Don’t forget to set the cat sensor (reset button) - one push of reset button when the unit is at the home position, while the blue LED light is solidly illuminated and the waste tray is empty. This will tune the cat sensor, especially if you add new or a lot of litter (not needed all the time, but good to do occasionally).
