My clipper/trimmer seems to pull the hair rather than cut it-does this mean I need new blades?
When your blades start to pull the hair the first thing to try is apply two drops of clipper oil to the blades and test cut again. (Oil lubricates the blades and allows them to run at the correct speed and ensure better cutting. It also helps the clipper run cooler. If your clipper blades are still pulling the hair, you will need to replace your blades or alternatively have them sharpened.
