Brushes are generally good for up to 200 hours of use. It will be noticeable in clipper performance when it is time to change the brushes. Generally, clippers will begin to slow down, run roughly, and then stop working.
Only clippers with a universal motor require greasing - for example, the Classic 76, Model 10 or Turbo 111. In order to grease the clipper, remove the front cover plate (nameplate) to access to the gear box. This will allow you to determine if the clipper needs to be greased. If clipper does need grease, use about 1/2 teaspoon. Fill the gear box with the grease. Make sure the grease covers the gears. Most of our products come packed with a grease tube. If you do not have one, you can order directly from our website.
Over time the socket on your blades may have become damaged. Check the "wings" on your blade socket to see if they may be bent outward or broken.
With the clipper facing you, place the pad of your thumb on the blade and swiftly push the top of the blade away from the clipper. This will make the blade '"tongue" or "blade assembly" open and you can slide the blade off. off the "tongue" and replace the new blade on the "tongue". With the "tongue" open, turn clipper on and then push the blade towards the clipper (shut), this will ensure the proper engagement of the blade on the driving tip.
First, ensure that the rectangular metal "tongue" or blade hinge assembly is in standing position or open. If it is closed, insert a flat head screwdriver under the tongue and applying enough force, push the hinge back to standing position. Once this is complete, slide the blade on the tongue, turn your clipper on and push the blade down and snap the hinge assembly closed
