Remove the battery from the clipper and check that the terminals are free of foreign objects and dirt. Insert the battery pack into the charging bay on the charging stand so it attaches to the connectors. The LED signals will illuminate with a continuous light at the current charge level to signal that the battery pack is now charging. Once the battery pack has finished charging, the 3 LED signals on the charging stand will switch off. Once the battery pack is fully charged, push the charged battery pack into the clipper until the battery pack latch engages on both sides.
