Install the brush head on the pole, (if you use a power drill, go ahead and install the hex pole) 3. When you start off go slow and clean out 2-3 feet at a time and pull the brush back towards you to bring all the dust junk back to or down to you. Going vertical to push the junk out won't work. However horizontal may work for you. 4. Get someone to do the drill work for you as you guide the rod and brush in and out of the pipe. As you go in pull it back and forth and then go in further. Once you have done about 3 feet pull it all back out to bring the junk back to you. 5. WEAR A MASK !! There will be dust everywhere.

WARNING:Please do not bend the rod connecting the electric drill. If you have to bend, the bending angle should not exceed 30 , and please turn it at a very, very slow speed. Otherwise, the product will be damaged by you! WARNING: When the length of the pole is greater than the length you need to use. Please remove the extra poles. Otherwise, the redundant rods will be twisted together due to the rotation of the electric drill, and the rods will be damaged! Specification: xPlease understand that there will be a
