●
Position the HVZ over the stone layer, which shall be gripped.
●
Turn the HVZ in such a way by means of the hydraulic rotator that it can be lowered over the stone layer
which can be gripped.
●
Swivel the HVZ in such a way, that the steel lamellas of the laying main clamping touch the stones.
Swivel further in such a way that the HVZ is in approximately centrically aligned to the paving stone layer
which can be gripped toward the side clamping.
●
Lower the HVZ, until the supporting feet of the HVZ affect the stone surfaces. Do not continue to lower
afterwards! The cross beam may not under any circumstances the HVZ essay be affected and thus pressure
from above on the clip be exercised (by the boom of the carrier ).
●
Hydraulic control lever on " Position 1" operate, so for a long time on this position hold, until the following
movements ran off:

main clamping closes

main clamping opens slightly

side clamping closes

side clamping closes

side clamping opens
Explanation: Positions of the control lever
Pos.1 : gripping, laying, reset
Pos. 0: zero position
Pos.3: back movement (ex.: a bend of cycle)
During appropriate use and attitude of positioning adapters the stone situation palletized on so-called "cross
joint" is shifted by this course of motion automatically into the "running bond".
When releasing the hydraulic control lever and/or by leading back the control lever into the central position the
gripping trial can be broken off at each time. By a new movement of the control lever on "close" the operating
procedure will be continued at the stopped position. When moving control lever on "Position 1/open" the last
movement will be reset.
●
Lead back the hydraulic control lever after completely locked grab procedure (side clamping opens perfectly
and swivels completely upward) into the central position.
●
HVZ with the gripped layer of stones situation carefully raise and to the shifting place swivel.
●
Place the paving layer 5 cm in direction to the open laying ground until the rollers touch the already laid
paving stones.
●
Move the paving layer diagonally to the corner of the laying edge and take care of the correct connection to
the already laid paving stones.
●
HINT:
Don not try to „tip“ the paving layers in side clamping direction with the already laid paving stones.
This is not possible, because the paving layers in the clamp are compressed and the already laid paving stones
are unconsolidated. It is better to either remove the “key - stones” before laying and later bring it back or lay
additional paving stones after the complete laying process.
●
By manipulation of the control lever on "open" and hold the control lever in this position few cm the main
clamping opened, the stone layer are thus released, so that them are put down into the facing bedding sand.
●
Move the control lever back into the central position.
●
The HVZ lifts up.
