OPERATION

[*1] Presetting number of impacts is impossible for more
than 200 impacts (4 seconds).
[*2] Fastening time includes when you pull the trigger
completely.
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between
fastening torque, fastening time and number of impacts
(presetting number) is shown in the figures.
Hold the tool firmly and place the point of the driver bit
in the screw head. Apply forward pressure to the tool to
the extent that the bit will not slip off the screw and turn
the tool on to start operation.
