If you find your blades getting hot too often, they might need some oil. Before turning on, the clippers spread a thick layer of clipper oil across the top blade then run it for around 30 seconds. Clipper lotions and oils are good in reducing friction between the upper and lower blades and protecting your clipper blades from wearing out prematurely. It also helps the motor run well since the oil makes the blades run smoothly for dipping blades to cool and disinfect and is also a good option when clipping many horses to prevent cross-infection. You also need to add oil after using coolant or disinfectant.
