The batteries used in this test are as follows: Model DS 10DFL: 1.5Ah B : 1.3Ah C : 1.3Ah * : Number of machine screws fastened per charge *1: Number of holes or fasteners per charge The table above shows examples of test data obtained using the battery provided as standard for this tool. Since the actually measured values listed in the table above may vary depending on the sharpness of the drill bit, workpiece hardness (particularly for wood materials), the moisture content of wood, charging conditions, and operator skill. This data should therefore only be used as a comparative guide. -6-
