Maintenance and Care

Replacement of the Battery
Never place the handpiece in the charger without the
battery inserted in the handpiece!
Use 3M ESPE batteries only! The use of other manu-
facturer batteries or non-rechargeable batteries/primary
batteries is a potential hazard and may damage the
device.
Rotate the lid at the lower end of the handpiece
counterclockwise until it hits the stop, and then
remove the lid.
Push a small spatula or similar aid between the
cylinders of the battery until the snap-lock releases
so that the battery protrudes slightly from the hand-
piece body.
Remove the battery from the handpiece.
Solution
Replace the battery.
Use a different power
outlet.
Have the charger repaired.
