Installingor removing battery cartridge
.Always switch off the tool before insertion or removal of the battery cartridge.
.To remove the battery cartridge, pull out
the
set plate and grasp both sides of the
cartridge while withdrawing it from the
tool.
0 To install the battery cartridge, insert the
battery cartridge into the housing and
snap the
set plate back intoplace. Be sure
to close the set plate fully before using
the tool.
Charging
Plug the fast charger into your power
source. Insert the battery cartridge
so that
the plus and minus terminals on the bat-
tery cartridge are on the same sides as their
respective markings on the fast charger.
Insert the cartridge fully into the port
so
that it rests on the charger port floor.
Press the start button (red). The charging
light will come on and chargingwill begin.
If the charginglightdoes not come on, press the reset button (yellow)first, then the start
button (red). If the charginglightgoes out within
10 seconds even after pressing the reset
button and start button a couple of times, the battery cartridge is dead. (CAUTION : Wait
for more than
5 seconds after the charginglight goes out to press the reset button again.)
Replace it with a new one. When the charging light goes out after about one hour, you
may removethe fully chargedbattery cartridge.
After charging, unplugthe charger from the power source.

:
0Your new battery cartridge is notcharged. You will need to charge it before use.
0 Do not keep the button pressed inwith 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-operated tool, sometimesthe charginglight
will not come on, If this occurs, let the cartridge cool off for a while. Then re-insert it
and try tocharge it once more.
When you charge a new battery cartridge or a battery cartridgewhich has not been used
for a long period, it may not accept a full charge. This is a normal condition and does
not indicate a problem. You can recharge the battery cartridge fully after discharging
it almost completely a couple of times.

Hold the tool firmly and place the point of the driver bit in the screw head. Apply for-
ward pressuretothe
tool to the extent that the bitwill not slip off the screw and turn the
tool on tostart operation.
NOTE :
0 Use the proper bitfor the head of the screw that you wish to use.
0 Hold the tool pointed straight at the screw.
0 If you tighten the screw for a time longer than shown in the figures above, 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 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.
0 When tightening screw M6 (1 /4") or smaller, carefully adjust pressure on the trigger
switch
so that the screw is not damaged.
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
tightening torque 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
tightening torque.
