Under desk treadmills are similar to regular treadmills or other electronic fitness equipment; they will require occasional maintenance and consistent care. You should make sure not to overwork the motor, and adhere to the weight capacities in order to reduce the strain on the machine.
While treadmills are durable enough to handle daily use, there’s a chance that you’ll still need to take care of the belt if it becomes worn away to ensure safety. You also must lubricate the wheels and motor to keep it operating at top performance. Some models will supply a bottle (or bottles) of gear lubricant to make this possible.
You won’t need to do this too often, but three or four times a year should be enough to keep it in top condition and prevent the gears and parts from grinding away at each other.
