To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
NOTE:
•
If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and
the bit will not be secured. In this case, try
re-inserting the bit according to the instructions
above.
OPERATION
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 and fastening time 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.

NOTE:
•
Use the proper bit for the head of the screw/bolt
that you wish to use.
•
Hold the tool pointed straight at the screw.
•
If you tighten the screw for a time longer than
shown in the figures, the screw or the point of the
driver bit may be overstressed, stripped, damaged,
etc. Before starting your job, always perform a test
operation to determine the proper fastening time for
your screw.
•
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
