10.5 Calibration of charger indication panel
If the external accumulator 7 Ah 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 is automatically calibrating the indication
panel again.
10.6 Safety advice for spare accus:
- Don’t throw them into fire.
- Protect them against humidity.
- Avoid short circuit (e.g. through metal parts) on the electric plug.
- Dispose of used accus properly.
11 Loading the quick-change accu into the LKE 55
The accu is charged automatically by placing it in the charging compartment of the charging device.
It is important that you read the operating manual of the charging device before charging.
12 Exchanging blade arms
- Unscrew the nut of the central bolt and drive out
the central bolt (double fixed spanner 32 x 36).
- Remove the retaining ring with a pair of Seeger ring pliers.
- Replace the blade arms after thoroughly applying
grease to the sliding surfaces.
- Tighten nut of LKE 50 / LKE 51 central bolt with100 Nm,
of LKE 55 with 110 Nm
and 120 Nm with LKE 70.
13 Preventive Maintenance
In order to ensure permanent proper function and safety for the rescue device, a visual inspection
has to be made after each use or at least once a year. Pay special attention to those parts which
carry loads, such as hinges or bolts. Also the rotary lever (1) (LKE 50 / LKE 51) resp. the star grip
(1) (LKE 55 / LKE 70) has to be checked for easy movement.
Every 3 years or if there is any doubt as to the safety or reliability of the equipment, carry out an
additional function and load test. The operational and load test should be carried in accordance with
the regulations of GUV.
Control of oil level and change of internal accu
The oil level has to be checked by trained personnel if the blade arms cannot be closed
completely.
It is recommended by LUKAS to have the oil changed by trained personnel after 5 years,
depending on the frequency of use.
