7• Low battery voltage:The remaining battery capacity is too low and the toolwill not operate. In this situation, remove andrecharge the battery.Indicating the remaining battery capacity(Only for battery cartridges with “B” at the end of themodel number.) (Fig. 3)Press the check button on the battery cartridge to indicatethe remaining battery capacity. The indicator lamps lightup for few seconds.015658NOTE:• Depending on the conditions of use and the ambienttemperature, the indication may differ slightly from theactual capacity.Switch action (Fig. 4)CAUTION:• Before inserting the battery cartridge into the tool,always check to see that the switch trigger actuatesproperly and returns to the “OFF” position whenreleased.To start the tool, simply pull the switch trigger.
