LOW HIGH The more the variable speed control trigger is pulled, the higher the speed becomes. • Do not operate the speed selector switch (LOW-HIGH) while pulling on the speed control trigger. This can cause the rechargeable battery to wear quickly or damage the internal mechanism of the motor. * See specifications for "MAXIMUM RECOMMENDED CAPACITIES". CAUTION: • To prevent excessive temperature increase of the tool surface, do not operate the tool continuously using two or more battery packs. The tool needs cool-off time before switching to another pack. • Do not close up vent holes on the sides of the body during operation. Otherwise, the machine function is adversely affected to cause a failure. • Do NOT strain the tool (motor). This may cause damage to the unit. • Use the tool in such a way as to prevent the air from the body vent holes from blowing directly onto your skin. Otherwise, you may get burned. Bit-locking Function 1. With the trigger switch not engaged and a screwdriver bit locked in place, the tool can be used as a manual screwdriver (up to 40 N•m, 408 kgf-cm, 353 in-lbs). There will be a little play in the chuck, but this is not a malfunction. 2. This feature is handy for tightening screws that require more torque than the maximum torque of the driver (position on the clutch), for confirming the tightness of a screw or to loosen an extremely tight screw. CAUTION: • Check the speed selector switch before use. • Use at low speed when high torque is needed during operation. (Using at high speed when high torque is required may cause a motor breakdown.) - 9 -
