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.
•
When it is difficult to insert the bit, pull the sleeve
and insert it into the sleeve as for as it will go.
•
After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
Hook
Fig.8
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
OPERATION
Fig.9
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.
•
When fastening screw M8 or smaller, carefully
adjust pressure on the switch trigger so that the
screw is not damaged.
•
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.
