1 Basic operation and designated use of the machine 1.1 The machine has been built in accordance with state-of-the-art standards and the recognized safety rules. Nevertheless, its use may constitute a risk to life and limb of the user or of third parties, or cause damage to the machine and to other material property. 1.
3.2 Make sure that nobody is at risk before starting up or setting the machine in motion and during operation of the machine. 3.3 Before transporting the machine always check that the accessories have been safely stowed away. 3.4 Make sure that there is enough lighting during work. 3.5 Avoid any operation that might be a risk to machine or to machine stability. 3.6 Check the machine at least after every operation for obvious damage and defects. Report any changes (incl.
Device-specific Information: Do not reach in between the blade arms! Do not cut electric wires! Cutting objects under tension (shock absorbers, springs, steering links) is prohibited since the cutoff parts of these objects might jerk away unpredictably which exposes the operator and other persons to a high risk of injury. Hardened objects such as spring steel must not be cut. Attention! A „deep“ dischargement of the accumulator must be avoided, i.
6.4 Close device (cutting) Turn rotary knob upwards and start the tool. The direction/operation process of the tool can be changed even when the tool is activated. 6.5 Safety switch off If the max. working pressure is exceeded only the hydraulic pump is automatically switched to "idle" (this can be deduced audibly), 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 suitable location. 6.
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.
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.
8.4 Opening of tool arms The LKE 55 motor starts automatically when the star grip (1) is turned to either "opening" or "closing". Turning the star grip to the right means causes the arms to open (= spreading). 8.5 Closing of tool arms The tool arms are closed (= cutting) by turning the star grip (1) to the left. 8.6 Load holding function / dead man's function As soon as the star grip is released it automatically returns to the neutral „zero“ position which includes also a load holding function.
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.
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.
If the capacity of the installed accu constantly decreases despite proper charging, it must be replaced by a qualified person. Maintenance advice Apply oil to the metal surfaces of the device from time to time except the electrical contacts. 13.1 Oil for LUKAS hydraulic devices Mineral oil in accordance with DIN 51524 HLP 10, recommended range of viscosity: 10..200 (mm2/s).
