Tips: 3 common troubleshooting for wet/drywall/floor sander.

1. The motor is hot during the sander operation
   The older the sander, the higher the heat will be. If you don't deal with this problem, the fever will get worse. If there is a noticeable oily smell when using the sander, the heavier lubricating solids in the grease in the gearbox have been broken down. At this point, open the sander gearbox, clean up all old grease and replace it with bearing grease. Apply grease to the gear teeth and fill all backlash. Be careful not to leave too much grease in it. A gearbox with new grease allows the sander to work for a long time.
2. Sander brush is worn serious
   If the sander switch is on but machine is not responding, it is most likely due to severe brush wear. As a power tool that operates for a long time under high load, brush wear of a sander is a very common phenomenon. Brushes will not all wear out in one use. Slow start-up may occur when you start using a sander. Many users will solve this problem by shaking or tapping the sander. In fact, it will only make the sander damage more serious. When brushes are completely worn, the sander will not start. At this point, the sander brush should be replaced to ensure its normal operation.
3. Sander uneven sanding
   Although the sander only sands a relatively small amount of material at a time during work, it is still easy to uneven surface sanding. When using a sander, always keep the sanding disc flat, sand on overlapping path and follow the material texture. In addition, it is necessary to ensure that the work is done by the weight of the sander itself, not by the pressure applied by the user himself. If the sander is hard pressed against the material surface, it will reduce the speed of sanding disc, resulting in a decrease in the working efficiency of the sander. To ensure a uniform sanding effect, can use a pencil to draw a curve on the material surface to be sanded and sand the mark at a uniform speed.
