0 Your new batterycartridge is notcharged. You will need tocharge it before use.
.Do not keep the button pressed in with tape, etc. or the circuit will not function pro-
perly.Also,
a malfunction of the charger may result possibly causing overheating, etc.
0 If you try to charge a cartridge from a just-operatedtool, sometimesthe charging light
will not come on. If this occurs,
let the cartridge cool off for a while. Then re-insert it
and try to charge it once more.
When you charge a new battery cartridgeor a batterycartridge which has not been used
for a long period, it may not accept a full charge. This is a normal conditionand does
not indicate
a problem. You can recharge the battery cartridge fully after discharging
it almost completely a couple of times.
0 If you wish to charge two battery cartridges,allow 15 minutes betweenchargings on the

go. Then release the
sleeve to secure the
bit.
To remove the bit, slide the sleeve toward
the motor and pullthe bitout 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
accordingto the instructionsabove.
CAUTION:
Before inserting the battery cartridge into the tool, always check to
see that the trigger
switch actuatesproperly and returns to the
"OFF" position when released.

Hold the tool firmly and place the point of the driver bit in the screw head. Apply for-
ward pressure tothe 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 bitfor the head of the screw that you wish touse.
Hold the tool pointed straight at the screw.
If you tighten the screw for a time longer than shown inthe figures above, the screw or
the point of the driver bit may be overstressed, stripped, damaged, etc. Beforestarting
your job, always perform
a test operation to determine the proper tightening time for
your screw. When tightening
a standard screw in a steel plate, the proper tightening
torque can be obtained in an extremely short time (approx.
0.1 -- 0.2 seconds). Turn
the tool off
as soon as the impact sound is heard.
The tightening torque
is affected by a wide variety of factors including the following.
After tightening, always check the torque with
a torque wrench.
1. When the battery cartridge is discharged almost completely, voltage will drop and the
tighteningtorque will
be reduced.
2. Driver bitor socket bit
*Failure to use the correct
size driver bit or socket bit will cause a reduction in the
tighteningtorque.
3. Bolt
Even though the torque coefficient and the class of bolt are the same, the proper

affect the torque.
CAUTION
:
If the tool is operated continuously until the battery cartridge has discharged, allow the
tool to rest for
15 minutes before proceedingwith a fresh battery.
