Beat the Heat! July 07 2016
I just repaired a clipper and had it running with a blade attached for around 20 minutes. The clipper works great, but the blade was as hot as the safety briefing on a Caribbean cruise ship (long story).
There are two main factors that contribute to blade heating.....speed and friction. Clippers are getting faster and more powerful, so try clipping at the lowest speed setting that you can.
You can reduce friction and cool your blades during use by lubricating them with a variety of products such as Andis Blade Care or Wahl Blade Ice. Be sure to oil your blades as well, putting a small amount of blade oil on the contact ride lines between the comb and cutter blades, and don't forget to put a drop or two of oil on the plastic blade guide.
I know that Groomers are all super hot...but that doesn't mean that your blades have to be....Andy
