Operation
To transport the device without gripping goods, it is done in the "emty stroke position" (see Ill. I).

This is achieved, when the gripping good is lowered on the ground and the empty device (WEZ) without
gripping good) is lifted.
Lift the device approx. 20 cm from the ground, pull out the spring pin (1) and turn a little at the same time
until it clicks into place (now the device can be transported on the carrier (eg. excavator) - without the
grippers closing accidentally.
As soon as the device comes back to work (ligting of L-stones), the automatic release (2) must first be
unlocked again (→ Ill. J 1).
For this the device must be positioned on a level ground!!
Otherwise, there is a risk of injury (due to uncontrolled movements of the device)
Pull spring cotter (1) out again and turn by 180 ° (→ Ill. J).
