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 tool can be used in two ways; a straight type and a
pistol type which is selectable according to the
conditions of workplace and screwdriving.

CAUTION:
• When bending the tool to use in the pistol type or
straightening to use in the straight type, do not hold
the bendable part of the tool. Failure to do so may
cause your hand and fingers to be pinched and
injured by this part.
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.
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.

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.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2. Driver bit or socket bit
