Black & Decker 8124 type 7 - brush replacement

I am trying to replace the brushes on a Black & Decker electric hedge trimmer model 8124 type 7 (120 volts). In trying to remove the brushes, I must have done something wrong. The brush holder did come out but a little plastic bump seems to have broken off. Is there a trick to removing the brush holder/brushes without damaging the holder? Would appreciate if someone has done this before and knows the trick or sequence of dismantling this part.

Thanks

SOURCE: Describe your Black & Decker Hedge Hog

You may have a piece of metal between the moving blade and the stationary one. Also the motor may have been at the top of the stroke when it stopped. You may be able to "force" the blade to move a little. This may free it enough to work.

your trimming a lot of hedges if you need to replace the brushes. I'd suspect other problems before that.

My Black & Decker trimmer starts and stops whenever I move the trimmer in any direction -- any advise as to how to solve this problem?


I'm not familiar with your machine, BUT... that description of symptom sounds suspiciously like a bad/poor electrical connection.

The problem could be in many places:
  • plug
  • cord
  • switch
  • brushes
  • internal electrical wiring
The "solution" to this problem is for someone who knows what s/he is doing, to troubleshoot the defective machine, determine the defect, and properly repair or replace the defective part.

My motor brushes at end of life for a Black and Decker electric leaf blower. Where can I get them? Black and Decker leaf hog, model BV400 type 4, Cinderson 90510850 motor. Black and Decker site no help...


Try Platt Electrical supply - 800-257-5288 (Platt.com) BLACK & DECKER #89754-01 REPLACEMENT BRUSH. It seems the entire motor head was manufactured by DeWalt and is now obsolete. I don't know if these brushes will fit, but someone there may help.
Good Luck!

How to Sharpen a Black and Decker Hedge Hog sharpen-black-decker-hedge-hog-800x800.jpg Maintaining the sharpness of electric timmers can made landscape trimming easier with beautiful results. Electric hedge trimmers make trimming hedges and bushes easier and quicker than using manual hand-powered trimmers. Electric trimmers, the most popular type in the U.S., cost less and require less maintenance than gasoline-powered models. Electric trimmers are used most often by homeowners with the Black and Decker Hedge Hog series being very popular. While they are not premium products, electric trimmers like the Black and Decker Hedge Hog trimmer can keep trimming reliably for years with proper maintenance, including sharpening the blade's teeth.
Difficulty: Moderately Easy Instructions Things You'll Need
  • Work table
  • Two medium size clamps
  • Dremel tool or similar hand-held multi-purpose tool
  • Grinding wheel attachment for hand-held tool.
  • Dremel 971 (or similar) aluminum oxide grinding sharpening stone with a tip small enough to cover the flat facet of a Hedge Hog blade tooth
    • 1 Unplug the electric trimmer before trying to sharpen the teeth.
    • 2 Clamp the electric trimmer to the work table using two clamps if necessary so the Hedge Hog is firmly held down with the blade teeth accessible over the edge of the work table.
    • 3 Insert and secure grinding tip in hand-held multi-purpose tool.
    • 4 Maneuver the grinding tip so it is perpendicular to the facet of the Hedge Hog tooth.
    • 5 Sharpen teeth in one direction, being careful to try and maintain the same cutting edge angle on the sharpened tooth of no less than 35 degrees.
    • 6 Make same number of grinding passes/grind the same length of time a few seconds on each tooth.
Tips & Warnings
  • This task should take about 15 minutes.
  • Keep a light touch; too much force can break the grinding surface.
  • For best results, insert the sharpening bit slightly less than all the way into the tool.
