Following your guidelines to diagnose the problem, ordered the parts (brushes and switch).
Remove screws holding 2 halves of the body together. Separate the 2 plates, exposing the motor. Carefully pull out the end portion of the light springs holding the brushes in their channel with a fine tweezer. Remove the brushes utilizing gra vity (tip motor and tap gently). Place new brushes into in their channels and reposition the holding springs onto the ends of each brush. Lift the switch off its plastic \"pillars,\" remove wires connected to it. Attach wires, as before, to new switch and slip new switch back into place. Screw 2 halves of the plastic body back together.

Struggled to find Torx Security drivers at local hardware stores that would work. Finally had to order online.
Once I had correct T15 driver, repair was a breeze. Removed screws holding body together and removed cover. Lifted spring clip holding brush and removed brush with needle nose pliers. Inserted new brush and replaced clip. Same on opposite side. Reassembled body and repair was complete. Runs like new.

Hedge Hog 24\" trimmer was intermittent when running and stopped operating when shifted up and down.

I opened the plastic case with Phillips and Torx drivers;
I noted the two severely worn brushes and a broken wire from the switch to the armature -- resoldered it. I found that sometimes the switch worked properly and sometimes it didn\'t. I replaced both brushes (first raising the small brass retainer springs) and replaced the sw itch and then reassembled the case and had the same intermittent running problem as before when the unit was turned, shifted and extended during use.

I then opened the unit again and carefully studied the pig-tail power cord. I used my volt/ohmmeter to find an intermittent short in continuity due to a broken white wire in the cord. I removed the old power cord, inserted the new power cord, attached the black wire to the switch. I shortened and stripped the end of the original white wire to the armature winding wire and then used a small wire nut to connect the two ends of the white wires in the handle and reassembled the unit. It works perfectly now without any problems.
Thanks for your videos and informative website.
