charged, all meter lights are illuminated (Fig.40).
As the machine is used and the batteries are discharged, the battery charge level meter
lights will go out from top to bottom.
If the battery charge level is allowed to discharge to the point that only one red light remains
illuminated, the operator should charge the battery.
