Automatic Power­off Function - Panasonic EYFLC1A Operating Instructions Manual

(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.

Automatic power­off function
• The automatic power-off function is designed
to prevent a loss of tightening torque due to
reduced battery voltage. Once it has been
activated, the tool will not operate until the bat-
tery pack has been charged (or replaced with
a fresh unit), even if the trigger is depressed.

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
after activation of the automatic power-
off function. Failure to do so may prevent
the automatic power-off function from
being properly deactivated.
(3) Overheat warning lamp
Flashing
The overheating protection feature halts tool
operation to protect the battery pack in the
event of overheating. The overheat warning
lamp on the control panel flashes when this
feature is active.
• If the overheating protection feature activates,
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 activate
repeatedly.
Adjusting the maximum
tightening torque
If the tightening torque is too high, it can be
lowered by limiting the maximum generated oil
pressure with the relief valve.
1. Place the forward/reverse switch in the
locked position and remove the battery pack.
Using a narrow-bladed flathead screwdriver
or similar tool, remove the rubber stopper.
