Bodyguard treadmill maintanance

After lubricating the treadmill also have to go into a menu called 'maintenance' and reset the average current or it will not compute a current based on the new lubricated treadmill.

this is not documented as far as I can tell.

Use up/down arrow keys on right hand side to go through the diagnostics menu until you find the current test, then select reset average.
