To operate the StairMaster stepmill correctly at the start of your workout, as well as when it's time to turn it off, consult manual provided with your machine. Knowing how to use this or any heavy-duty cardio machine are helpful. Not every machine turns on and off like most others. There is a proper sequence in which to turn on the machine and make sure it is turned on safely. That means verifying that the console is ready to take commands, that the emergency stop cord is not pinched, and so forth. To shut down the machine, let the steps completely stop turning and then toggle the main switch off or cut the power. Skipping this process will result in mechanical strain to the drive system and motor over time, potentially causing error codes. Because of their familiarity with consumer treadmills, many homeowners of home gyms don't go through all this in detail. Since a stepmill has a continuous stairs mechanism, its mechanics aren't as simple. If you turn the machine off incorrectly, you might have problems. Does turning off the device make it last longer, the way the manual says? Or was that just preventative cautionary advice? The documentation stresses both right usage and safe use, yet we see in reality people don't follow instructions as closely than one would think.
