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. This means that the tool arms stay safely in their last position
even with the motor switched off.
8.7 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 55.
8.8 Motor temperature
The housing of the LKE 55 contains ventilation slits to prevent the motor overheating. These must
never be covered when the motor is in operation.
Furthermore, ensure that no dirt or moisture can enter. The device is not damaged if it is used in
the rain, so long as it is stored in a dry location.
8.9 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.
9 General remarks for working with LKE
9.1 Cutting
The blade arms must be applied in a right angle to the object to be cut. To enhance cutting
performance, cut as close as possible to the round stock cutting edge.
