Lukas LKE 55 - Manual (Page 9)

When the charger is switched off or disconnected from its electric supply, the LKE 70 (or the
external accumulator) must be disconnected from the charger. Otherwise the LKE 70 (or the
external accumulator) would be slowly discharged.
This discharging process will not be shown on the charge indication panel, i. e. it would shown "full"
even when the device is partly discharged. The charge indication panel will work correctly again
once the tool has been fully discharged (see item 7.10).
7.10 Calibration of the charge indication panel
If the LKE 70 is frequently partially discharged, but then fully charged again, the preciseness of the
indication panel could suffer. To prevent this, the accumulator should be fully discharged at least
after 5 operations. A full discharging automatically calibrates the indication panel again.
7.11 Motor temperature control
The LKE 70 is equipped with a motor temperature control. If the permissible motor temperature is
exceeded, the LEDs of the capacity control panel blink. If this happens, the tool should be switched
off immediately.
Only in an extreme case should the rescue work be continued, however with the risk of a motor
damage.
7.12 Safety switch-off
If the max. working pressure is exceeded only the hydraulic pump is automatically switched to „idle“,
but the pressure in the system is maintained. In this case the tool arms don’t move any more.
Reposition the tool and start working again at a more preferable position.
8 Operating the LKE 55
8.1 First commissioning
The quick-change accu must be charged before the device is used for the first time.
8.2 Changing the accus
In order to change the accus, press both release buttons (4) down completely, and pull the accu
out backwards.
When inserting the accus, ensure that they audibly click into place.
Pay particular attention that no foreign material can enter the battery compartment when the accu
is removed, since this will damage the contacts when the accu is reinserted.
8.3 Starting the LKE 55
The device is driven by the accu, an electric motor and a hydraulic pump.
In order to be able to use the device, the main switch (2) must first be in position "I". The device
is now ready to be operated, but the motor is off.
