The importance of change the belt in due course

All the belts have a lifespan and when the engines overheat for the effort this is almost always due to the high coefficient of friction between belt and base.
Does the belt stop or doesn't seem to have the strength to carry the person using the treadmill? Do you notice an excessive consumption (high amperage)?
This is a warning signal that the belt or the deck are in bad shape and need to be replaced urgently.
If you don't change the belt, the motor brushes wear out faster (for DC motors) and you risk compromising your controller (both for DC and AC motors). The smell coming out from motor that sometimes smells like "burnt paint" indicates that the windings are overheating and protective resin is likely to melt. If we do not control and settle belt and deck, sooner or later it will happen the same thing even with a new motor. Belt manufacturers indicate a useful lifespan of two or three years. In practice, for domestic use a standard belt lasts 3-4 years, a quality one up to 5/6 years. In the gym lifespan does not exceed more than 2 years.
It is important for treadmill owners to understand what they must replace regularly, therefore establishing in advance the expenses and the amortisation of their investment.
A preventive maintenance pan for treadmills: things to do at least every two months for commercial use (gyms)
Basic cleaning (dust and impurities) with suitable, NOT aggressive, cleansing agent.
Vacuum the engine compartment (NO water, use a vacuum cleaner and do not touch directly the electronic components).
Motor control (check brushes if DC motor).
Check the drive belt and its tension
Inspection of the controller (connectors).
Tilt motor control (functional tests and cleaning/lubrication of screw only).
Cleaning and lubrication of the deck.
Belt monitoring: upper and lower side inspection, cleaning, lubrication with spray lubricant for treadmills, tension and alignment/centering.
Checking/cleaning the rollers and the drive system.
Where necessary: calibration of the speed.
Amperage testing with no load and with load.
Final functional test with no load and with load.
