Arlec Ceiling Fan Bunnings - You know what? The name of this informative article is just out and out misleading. The only actual "minus" in regards to some ceiling fan is what it requires to get one correctly installed. Ceiling fans may be difficult to install for the inexperienced do-it-yourselfer. Sometimes, you will need to run an electrical line to the region where the ceiling fan will be installed. Unless you're adept at doing this sort of thing, hiring an authorized, bonded and competent electrician will more than likely save you much grief in the long run.
There's also the minor "minus" that involves the issue of periodic care. Properly installed, a ceiling fan will give you many, many years of enjoyable cooling and cost-savings on your heating bill (assuming there is a fan that enables one to reverse the blade direction).
On occasion, ceiling fans get out of balance and require slight alterations. The most common culprits are loose screws that attach the blades to the motor housing, blades that are not at exactly the same angle (pitch) as the rest of the blades as well as a blade or blades that weigh slightly more than the others. Be sure that all the screws are tight, without going into great detail. If they truly aren't tightening the ones that have come loose and run the fan. Your issue has been solved, when the wobbling has ceased.
Otherwise, make use of a yardstick or other straight part of wood and place it (with the fan quit) vertically at the outer edge of one of the blades. Rotate the blades by hand to make sure that every blade touches the stick.
