4. When braking, it is normal to hear clicking before the sand tablet stops. If the sand tablet makes unusually loud noises, remove it, and use the included hex-wrench to adjust the screw on the back cover (18)
5. To check if you need to replace the abrasive disk, rotate the disk by hand and estimate: if the platform jumps more than 2mm, change the disk. After replacing the disk, make sure to tighten the ring on the platform 8 (closest to the outside of the sand tablet)
