The New Hotness

  • Craftsman Hedge Trimmer: Biennial Laying On Of Hands Repair

    Once again, the hedge trimmer failed to turn on with the switch pressed, so I took it apart, did nothing, and had thing start working again:

    Craftsman Hedge Trimmer - innards exposed
    Craftsman Hedge Trimmer – innards exposed

    It finally penetrated my dim consciousness: perhaps the switch is fine and a carbon brush (or two) has lost contact with the commutator atop a layer of oil and dust.

    So a year from now when this happens again, try jamming a screwdriver through a vent slot and moving the motor a few degrees to jostle the crud.

    If it works, that would be much easier than taking it apart!
