It is common for the railings and wheels to lose their smoothness over time, but there are a few steps you may take in order to get your slider moving as smooth as new again.
The video below will explain how a SliderPLUS should be cleaned in order to eliminate bumps.
While cleaning the wheels and railings, we suggest checking for cracks or scratches of any kind. If you detect a scratch or dent on your railing, please reach out to our Support team to receive a repair on your SliderPLUS.
You may also adjust the amount of contact between wheels and the rails to achieve a smoother slide, which is demonstrated below.
