9.2 Spreading
Use the frontmost area of the tips only for enlarging the gap. The maximum spreading force can
be applied if approx. 50% of the grooved section of the bladearm tips is used.
9.3 After Operation
The blade arms should be closed up to 5 to 10 mm. This relaxes the device hydraulically and
mechanically.
10 Use of external accumulators
(only for LKE 50, LKE 51 and LKE 70)
10.1 General
Both LKE 50 / LKE 51 and LKE 70 can be connected to external accumulators. Following
external accus are available:
- 1.7 Ah - external accu in a robust leather cover,
ref. no. 84150/7021.
- 7 Ah - external accu in stable plastic housing, ref. no. 84150/7028.
Both accu types are suitable for LKE 50 / LKE 51 and LKE 70.
10.2 Charge indication with external accu 7 Ah
The 7Ah external accu is equipped with a charge indication panel similar to the one on LKE
70 (see also item 7.7). The panel is activated as soon as current is flowing, i.e. during
charging as well as during discharging.
The panel automatically switches off after charging / discharging. It does so after a delay of approx.
30 minutes to allow it to be read during short breaks in the work.
10.3 Charging the external accumulator
The external accumulator 1.7 Ah (in leather bag) is connected to the charger with the black
charging cable (ref. no. 84150/7022). Charging is then carried out automatically.
The external accumulator 7 Ah is connected to the charger with the built-on cable (see operating
instructions for the charger).
The external accumulator discharges slowly when the charger is switched off or disconnected from
its electricity supply. This discharging process will not be shown on the charge indication panel, i.e.
it shows "full" even if the accumulator is partly discharged. The charge indication panel works
correctly again once the accumulator has been fully discharged (see item 7.10).
10.4 Acoustic signal when the accumulator is empty
Like with the LKE 70, also the 7 Ah accumulator includes a signal indicating that it is becoming
empty (see also item. 7.8).
