+## Wheels
+
+There are two wheels mounted a white one which is softer and a yellow one which is harder.  
+One approach is to apply the polish using the yellow one, then buff it out with the white one.  
+To remove polish from the sheels use a flat bladed screwdriver.

+## Risk Assesment / Training
+
+The training for the bench grinder will cover the training for the polisher.  
+Full PPE should be worn which includes a face mask and avoiding wearing loose clothing.  
+this is due to the potential risk of something catching and being flown across into someone's face if let go.
