7.5 Load holding function / dead man’s function
As soon as the star grip is released it automatically returns to the neutral "zero" position which also
includes a load holding function. This means that the tool arms stay safely in their last position even
with the motor switched off.
7.6 Switching-off of the tool
After each operation the tool arms should be closed to a 5 to 10 mm’s gap. This relaxes the tool
both hydraulically and mechanically.
The main switch has to be set to "off" to prevent an unintended operation of LKE 70. If the main
switch stays "on" the accumulator would be slowly discharged by the LED indication panel (3).
7.7 Accumulator charge indication
LKE 70 is equipped with a charge indication panel (3) consisting of 5 LEDs which are lit
corresponding to the charge situation of the tool.
The panel includes 3 green LEDs
1 yellow LED and
1 red LED.
The tool accumulator is fully charged when all green LEDs and the yellow LED are lit.
Each LED represents 1/5 of the full accu capacity, i.e. when the red LED is on a charge of
20 % is still available.
Attention:
When the accumulator is deep discharged, a running light can be seen on the indication
panel. In this case the operation should be stopped immediately because the accumulator
could be damaged. The light is switched off again when the tool is charged.
7.8 Acoustic signal when the accumulator is empty
With model LKE 70 a signal is indicating that the accumulator becomes empty.
The signal sounds as soon as a rest capacity of 20 % is reached. It sounds 8 seconds and is
repeated every 24 seconds. Of course working can be continued until the accumulator is completely
empty.
The signal is interrupted when LKE 70 is switched off with the main switch (2), when an external
accumulator is connected or when LKE 70 is charged again.
7.9 Charging the LKE 70
LKE 70 is charged by connecting the LKE charger to the 24 V socket (5) on the tool. The grey cable
(order no. 84150/7023) has to be used for this purpose. Once the charger is switched on the
charging procedure starts automatically (see also charger operation manual).
During charging the charge indication panel works even if the tool's main switch is in the "off“
position. This enables the progress of charging to be checked visually.
The charging procedure may be interrupted at any time, if necessary. Just switch the charger off
and disconnect it from the tool.
Attention: Do not operate LKE 70 while it’s being charged !
