Failure of the motor can be one of the most expensive problems with a treadmill, so make sure to eliminate all other problems before diving into motor repairs. This should tell you what kind of problems are occurring with your treadmill motor. The manual may also tell you whether or not the problem can be fixed by you or needs to be fixed by a professional. Inspect the motor's connections. For non-experts, inspecting a motor might be fruitless. If nothing strikes you as being obviously wrong, you might need to consult a professional. Be warned, opening up your treadmill's motor is likely to void any warranties you may have on the treadmill. If your treadmill is still under warranty, it may be best to forgo any home repairs and go directly to a professional repair person. This step should only be undertaken if you have a lot of knowledge about motors and can easily read an electronics schematic. Treadmill motors can be purchased at exercise equipment outlets both online and in physical stores.

Q: Once you’ve detached the tiles from the floor, you’ll likely be left with smaller broken pieces scattered around. Use a broom and dustpan to collect these broken pieces and throw them away.  Keep your safety attire on for this step so that you don’t cut your hands or injure yourself. If necessary, you can vacuum up the dust and smaller pieces. You'll likely have leftover grout or glue that needs to be removed. This should come off the same way the tiles were removed by positioning a chisel or hand maul against the grout and scraping it off with the help of the mallet. Depending on the size of your floor, you may want to use a bigger chisel to reach a wider surface area at once. If you can’t remove all of the grout or glue, that’s okay. Use the chisel or hand maul to remove as much of it as possible, leaving just a thin layer (no more than 0.125 in (0.32 cm)) on the floor that can be filled in and covered up easily. Floor scrapers have a wider edge than a hand maul or chisel, as well as a longer handle, making it easier to scrape the floor. Use a floor scraper to smooth out any rough patches resulting from the tile or grout removal, pushing the edge of the scraper against the floor in precise, forward motions. You can find a floor scraper at a home improvement store or online. Use a Shop Vac or similar vacuum to pick up any extra pieces of tile, grout, or dust from the floor and surrounding surfaces. Go slowly when vacuuming to ensure you get everything. Thin-set mortar will help fill in the holes and uneven surfaces of the floor so that the removal of the tile and grout no longer looks bad. Apply a 0.125 in (0.32 cm) layer of thin-set mortar with a flat or square-notched trowel depending on whether you’ll be re-tiling the floor.  Follow the directions to mix the mortar properly before applying it. A square-notched trowel is helpful in making grooves in the mortar so that you can easily place new tile.
A: Sweep up the broken pieces of tile on the ground. Hit the chisel with the mallet to scrape off the adhesive. Leave a super thin layer of the adhesive, if necessary. Smooth the floor using a floor scraper. Remove any remaining dust using a vacuum. Apply thin-set mortar to the floor to make it level.

Article: Sway them from side to side. You should be able to complete a full sway that goes from left to right within one count of the four-count beat. Your arms should also cross in front of each other as you wobble your hips. Keep your arms crossing to the beat, as well. Your shoulders and hips will take turns swaying from front to back, causing your torso to wobble from front to back. When the hips are toward the front, your shoulders should be toward the back, and vice versa. Think of a waving flag. Try to mimic the way the flag waves, wiggles, and wobbles in the breeze using your torso. The easiest way to occupy your hands while you twist is to do a hand roll, in which your two hands circle each other front and back at the front side of your body, roughly at chest level. Do this hand roll to the beat. The hand roll is not the only move you could use, though. You could also point side to side, wave your arms, or do whatever else feels natural with your own personal groove. This part of the wobble is usually just improvised.
