Reading the Lamps

This charger is provided with a charging time lamp which displays estimated charging time, and a charging status lamp which displays the charging status.

(a)Charging Time Display

After beginning charging, the charging time lamp lights red with about 30 minutes remaining, lights orange with about 20 minutes remaining, and lights green with about five minutes remaining. When charging is complete, the charging status lamp lights green.

(b)High Temp Standby Display

Charging will not begin if the battery temperature is high. When this happens, the charging time of lamp flashes red (0.6 second cycle). Leave the battery in the charger, and charging will begin automatically when the temperature decreases.

(c)Charging Standby Display

Because the charger prioritizes power source output, charging is paused when the cordless tool switch is triggered during charging. When this happens, the charging time lamp will repeatedly flash (1 second cycle) in the current charging time display color (red/ orange/green). After the switch is released, charging automatically resumes in approximately one minute, and the lamp will light continuously.

(d)Unable to Charge Display

When the charger or the battery is malfunctioning, the charging status lamp flickers orange (0.2 second cycle). (See Table 2)
