Procedure 1
► Fig.8: 1. Driver bit 2. Sleeve
To install the driver bit, pull the sleeve in the direction of
the arrow and insert the driver bit into the sleeve as far
as it will go.
Then release the sleeve to secure the driver bit.
Procedure 2
In addition to Procedure 1, insert the bit-piece into the
sleeve with its pointed end facing in.
► Fig.9: 1. Driver bit 2. Bit-piece 3. Sleeve
To remove the driver bit, pull the sleeve in the direction
of the arrow and pull the driver bit out.
NOTE: If the driver bit is not inserted deep enough into
the sleeve, the sleeve will not return to its original position
and the driver bit will not be secured. In this case, try
re-inserting the bit according to the instructions above.
NOTE: After inserting the driver bit, make sure that it
is firmly secured. If it comes out, do not use it.
OPERATION
CAUTION:
When bending the tool to use in
the pistol shape or straightening to use in the
straight shape, 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.
The tool can be used in two ways; a straight shape and
a pistol shape which are selectable according to the
conditions of workplace and screwdriving.

Screwdriving operation
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
Use only these type of driver
bit. Follow the procedure
1. (Note) Bit-piece is not
necessary.
To install these types of driver
bits, follow the procedure 1.
To install these types of driver
bits, follow the procedure 2.
(Note) Bit-piece is necessary
for installing the bit.

NOTE: When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.

Drilling operation

First, turn the adjusting ring so that the arrow points to
the marking. Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained
with wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the drill bit into
the workpiece.
Drilling in metal
To prevent the drill bit from slipping when starting a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
CAUTION:
Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
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.
Using the tool as a hand screwdriver
► Fig.12
Switch off the tool.
Move the lock lever to the locked position
Turn the tool.
NOTICE:
Use the tool with a fastening torque less
than 5 N•m (50 kgf•cm).
NOTICE:
Do not use the tool for work requiring
excessive force, such as tightening bolt M6 or bolts
greater than M6 or removing rusted screws.
NOTE: This use is convenient for checking the
screwdriving.
