How to choose the length of the pole *400mm-410mm-570mm-600mm long. *The shorter the pole, the stiffer the pole. * Hardness : 400mm long PA material rod> 570mm long PA material rod> 410mm long PP material rod> 600mm long PP material rod. *Quality:400mm long PA material rod=570mm long PA material rod> 410mm long PP material rod= 600mm long PP material rod. *Recommend I recommend 400mm long PA material rodThis linkand 570mm long PA material rod. If you need a stronger rod, please purchase this linked product. The difference and choice between better resilience with Ordinary product Better resilience: Better materials. After bending, it has stronger recovery ability; it is not easy to break during high-strength work. It is suitable for scenes with complex usage conditions. For example: there are more than 3 elbows in the pipeline. Ordinary product: It is suitable for simple cleaning. High-intensity work is easy to break. If your usage scenario is very simple, you can choose the ordinary product in my store(Not this link). Special note: *If you receive the pole is white and hard. Don't worry, if you leave it exposed in the air for a period of time, it will absorb moisture in the air and become soft (it needs to last about a month). Because the white pole is just produced. The newly produced PA material is hard. * The pole sold in this link is the pole (PA) of the material I recommend in the video with good quality *If you receive the pole, it feels a little hard.Please don't worry The rod is made of PA, and the rod just produced is hard. It takes one month to absorb moisture in the air, and then it will become soft and more elastic.Please do not seal it and store it directly in the exposed air. It will absorb water in the air. Do not use water to water it, which may damage the rust protection of the screws. *The rod made of PA material is of very good quality. Please don't worry *The color of the pole is white and yellow, which are sent randomly *The actual length of the pole is 400-415mm. How to use 1. Connect a sufficient number of poles as needed; 2. 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. It will smell like fabric softener everywhere. 6.Caution:Rotate brush/rod(s) assembly only in a clockwise direction.Reversing the direction could cause the brush head or rod(s) to detach inside the duct. WARNING: Never force the brush/rod assembly through the duct If it should become jammed, pull assembly away from constricted area a few inches (still rotating in a clockwise direction) then slowly push forward. 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
