How do I alter the time on an analogue tachograph?
When you open the tachograph it flip’s forward on a hinge.This lid houses the speedo and clock.On one side of this,i think it’s the right hand side,you will see the top of a small white wheel,it’s grooved.this adjusts the clock.When you have reset the time put in a blank tacho card and drive forward a few feet,you will here the tachograph spinning for a second or two while it resets its self.And thats it. Remember you can’t see this little wheel when the lid is closed.
