Harley Davidson Ceiling Fan Pull Chain - You know what? The title of this article is simply out and out misleading. The only actual "minus" as it pertains to a ceiling fan is what it requires to get one correctly installed. Ceiling fans can be hard to install for the inexperienced do it yourselfer. In some instances, where the ceiling fan will be installed you will need to run an electric line to the region. Hiring a qualified, bonded and licensed electrician will probably save you a lot of grief in the long term, unless you are skillful at achieving this sort of thing.
There's also the minor "con" that entails the problem of regular maintenance. Correctly installed, a ceiling fan provides many, many years of nice cooling and cost-savings on your heat bill (assuming there is a fan that enables one to reverse the blade direction). Allowed, you should wipe the blades down once in a while but everyone has household cleaning chores to take care of from time to time.
On occasion, ceiling fans get out of equilibrium and need small adjustments. The most common offenders are loose screws that attach the blades to the motor housing, blades that are not at precisely the same angle (pitch) as the rest of the blades and also a blade or blades that weigh somewhat more compared to the others. Be sure that all the screws are tight without going into great detail. Whenever they truly aren't tightening the ones that have come loose and run the fan. Your issue continues to be solved, when the wobbling has ceased.
If not, make use of a yardstick or other straight piece of wood and put it (together with the fan stopped) vertically in the outer edge of one of the blades. Rotate the blades by hand to ensure that every blade touches the stick. Turn the fan on again and see if you've solved the problem.
