Control Panel - Panasonic EYFPA1C Manual De Instrucciones

CAUTION:
When the tool stops automatically after
the switch is released during impact-
mode tightening and then reengaged
within 1 second, the red lamp will light up
to indicate the risk of excessive torque
application as a result of retightening.
NOTE:
• The tightening confirmation lamp will not
turn on under the following conditions:
• When the torque clutch is set to "F"
• During reverse rotation operation
• The lamp turns off when the tool is in
operation.

(1) 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 preset
load value is exceeded. Driving is then auto-
matically stopped after a preset number of
impacts have been delivered to the bolt.
CAUTION:
• Always check the tool's tightening torque
before use. The required adjustment
is dependent on the type of threaded
connection and can be best determined
by practical trials. Check the trial screw-
ings with a torque wrench. Improper tool
operation may result in excessive or
inadequate tightening.
• Always operate the tool with the switch
fully depressed. The torque control func-
tion will not operate when the switch is
not sufficiently depressed, 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
generally increases with bolt diam-
eter.
• Torque coefficient (indicated by the
bolt manufacturer), grade, length,
etc.
) 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, man-
ner in which the tool's switch is
depressed
• Condition of object being tightened:
Ma-terial, seating surface finish
(2) The battery indication lamp
• Use the battery indication lamp to check
how much power is left in the battery.
• Battery life varies slightly with ambient tem-
perature and battery characteristics. The
lamp is designed to provide a rough indica-
tion of remaining battery life.
