This may help - just nicked it from another website so it refers to a balancing clip/kit but blu-tack or a bit of lead should do the trick fine.
1. To balance the blades, run the fan on high speed, down draft.
2. Before using balance kit, switch positions of 2 adjacent blades ( replace blade 'a' where blade 'b' was and put blade 'b' where blade 'a' was. ) If this improves the balance of fan, leave as is and proceed to step 3. If this makes balance worse, change blades back and proceed to step 3.
3. With the fan stationary, attach the balancing clip firmly on the leading edge of one blade halfway between at&127 the outer edge of the blade and the blade bracket.
4. Run the fan and observe the wobble. Stop the fan and move the clip to the next blade. Again run the fan and observe the wobble. Repeat this for all blades.
5. Move the clip back to the blade where you noticed the least wobble. This time attach the clip to the leading edge of the blade near the blade bracket, run the fan and observe the wobble. Stop the fan and move the clip outward toward the end of the blade in small increments until you find the position where the fan runs best.
6. Peel the protective paper off of one of the self adhesive weight strips, and stick it firmly on the top of the blade along the center line, opposite the clip. Remove the clip and start the fan. If the fan wobble was not completely stopped, you may be able to further improve it by repeating all of the above steps. Adding another weight to whichever blade is indicated by your second test, in addition to the one you put on the first time, may solve the wobbling problem.
Don't drink drive! Not only is it socially unaceptable, it also harms A2's.
