be reached when fully charged. This does not indicate a
defect.

Charge the battery pack.
Replace the battery pack.
Push the battery pack into the mounting
until it latches into place.
Stop working and allow the battery to cool
down to normal battery temperature.
Stop working and allow the motor to cool
