Important Note: It is very important to install the splash guard and control the amount of water used when polishing. You only need to keep the surface slightly wet to prevent dusts, otherwise water can go in the motor and lead to GFCI power protection to kick in and shut it down. When this happens, you need to wait for the motor to dry completely before push the RESET button on GFCI in order for the polisher to work again. This will cause delay in work time and affect motor life.
