NOTE:
• All 3 bars on the battery indication lamp
will flash when the automatic power-off
function is activated.
• When the battery indication lamp begins
flashing, the battery pack should be
charged (or replaced with a fresh unit)
immediately.
• Be sure to fully charge the battery pack
in question after activation of the auto-
matic power-off function. Failure to do
so may prevent the automatic power-off
function from being properly deactivated.

(3) The torque control function
• The torque control function calculates the
load from the motor's rotational angle during
the hammer impact and determines that the
bolt has been properly seated when a pre-
set load value is exceeded. Driving is then
automatically stopped after a preset number
of impacts have been delivered to the bolt.
CAUTION:
• Always check the tool's tightening torque
before use. Improper tool operation may
result in excessive or inadequate tight-
ening.
• Always operate the tool with the switch
fully engaged. The torque control func-
tion will not operate when the switch is
not sufficiently engaged, preventing the
tool from stopping automatically.
• In work where a heavy load comes to
bear during tightening, the load may be
interpreted as the seating of the bolt,
preventing the bolt from being completely
tightened.
• Repeated tightening of the same bolt
may break the bolt or deform the material
into which the bolt is being driven as a
result of excessive tightening.
• The tightening torque value and preci-
sion vary with factors such as the mate-
rial into which the bolt is being driven
and the condition of the socket being
used. Adjust the torque as necessary
for the work being performed. Bolt tight-
ening torque varies due to the factors
described below.
1) Bolt
• Bolt diameter: Tightening torque gener-
ally increases with bolt diameter.
• Torque coefficient (indicated by the bolt
manufacturer), grade, length, etc.
2) Other
• Bit and socket condition: Material,
amount of play, etc.
• Use of a universal joint or socket adapter
• User: Manner in which the tool is applied
to the bolt, strength with which the tool is
held, manner in which the tool's switch is
engaged
• Condition of object being tightened:
Material, seating surface finish

Setting the tool to
configuration mode
1. Turn off the control panel.
• If the control panel is on, remove and
then reinsert the battery pack.
2. Engage the switch while pushing the
button and then release both the
ton and the switch.
• After all the LED lamps have turned
off, the control panel will flash and
change to configuration mode.
[Fig.14]
NOTE:
• Tools ship from the factory set to "F"
mode (torque control function off).
• The control panel will turn off if the tool
is not operated for a period of 5 minutes.
