Panasonic EYFLF1XA Operating Instructions Manual page 73

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

(4) Overheat warning lamp
Indicates operation has been halted due to
motor or battery overheating.
To protect the motor or battery, be sure to
note the following when carrying out this
operation.
• If the motor or battery becomes hot, the pro-
tection function will be activated and the
motor or battery will stop operating.
The overheat warning lamp on the control
panel illuminates or flashes when this fea-
ture is active.
• If the overheating protection feature acti-
vates, allow the tool to cool thoroughly (at
least 30 minutes). The tool is ready for use
when the overheat warning lamp goes out.
• Avoid using the tool in a way that causes
the overheating protection feature to acti-
vate repeatedly.

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.

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.
