Details Provides adjustable cutting performance from fine to coarse Made in USA, the Andis Master replacement blade provides adjustable cutting performance from fine to coarse - 000 to 1 and leaves hair 1/50" (0.5mm) to 3/32" (2.4mm). Made with carbon-steel for a dependable, long-life that stays sharp. Directions • Use a clipper cleaning brush after each cut to remove fragments of hair from the blade. • Properly disinfect to kill germs and viruses by using Cool Care Plus.® Review the contact time necessary for proper disinfection. • Use the 5-point oiling system to lubricate your clipper and keep it running at top performance: 3 drops across the teeth of the blade and 1 drop on each back rail. • If you notice a decrease in performance after cleaning & oiling your blade, replace the blade to maintain peak cutting performance. Note: If you have a detachable blade clipper, consider replacing the blade drive at this time. • Keep your cord well cared for – never wrap it around the clipper. • Review the Use & Care instructions provided with your tool, as each one requires unique attention.
