Tips for maintaining maximum battery life
1. Charge the battery cartridge before

Always stop tool operation and charge the
battery cartridge when you notice less tool power
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life. CAUTION:

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out
any work on the tool.
CAUTION: Installing or removing driver bit or socket bit
• Do not look in the light or see the source of light
directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.

Reversing switch action
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will go.
Then release the sleeve to secure the bit.

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.
• 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.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
7
Page 8
2. Driver bit or socket bit
Failure to use the correct size driver bit or socket bit
will cause a reduction in the fastening torque.
3. Bolt
• Even though the torque coefficient and the
class of bolt are the same, the proper fastening
torque will differ according to the diameter of
bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class of
bolt and the bolt length.
4. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.
5. Operating the tool at low speed will cause a reduction
in the fastening torque.
