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.
CAUTION:
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 com-
pletely tightened.
Repeated tightening of the same bolt
may break the bolt or deform the mate-
rial 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: Ma-
terial, 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
but-
ton and the switch.
After all the LED lamps have turned off,
the control panel will flash and change
to configuration mode.
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 min-
utes.
