General

If the arm of the support frame (excavator) is moved (with a gripped stone layer) too far to the outside, a
risk of tipping of the support frame (excavator) - due to the weight of the installation clamp and the weight
of the stone layer. Therefore note the tipping stability of the support frame (excavator).
Attention!
●
Before using the device check the functions.
●
Adjust HVZ-UNI-II as shown in chapter "Adjustments".
The operating of the HVZ-UNI-II makes use of modern drum control.
The advantage of such technics is, that according to the job specification, the different motion sequence can be
activated via a selector switch.
●
It is not allowed to close the main gripping direction without a layer of paving stones when the side gripping
direction is closed, because the main gripper is pressed against the C-profile and will be damaged.
●
If you operate the HVZ-UNI very carefully it is possible to transport empty pallets. Take care that the hydraulic
pressure is not at the maximum clamping the pallet.
If you use the maximum hydraulic pressure the pallets will be damaged or the steel-lamellas or the main gripper is
damaged.
●
Operating the HVZ- UNI-II with an excavator, wheel loader or other similar equipment:
Make yourself familiar with the operating elements for the both hydraulic circuits (main / side gripping direction).
Especially remind the function for opening the main gripping direction, that there is no accidental opening while the
installation clamp is lifted up and the layer falls down.
DANGER OF ACCIDENTS!
Move the operating lever slowly and carefully, almost at idling speed, because the great hydraulic flows of big
excavators can cause malfunctions or even damages of the hydraulic installation clamp.
Be sure the hydraulic pressures correspond to the values in chapter "Authorized use".
●
Operating the HVZ- UNI-II with an Installation Machine (e.g. with VM-301)
Make yourself familiar with the functions of the joystick (on the right hand-side at the drivers seat). Impress yourself,
that the forward movement of the joystick opens the main stress.
In order not to activate these function of the joystick, while the HVZ-UNI-II is lifted up with the gripped stone layer
and so the layer falls down. DANGER OF ACCIDENTS!
●
For the selection of the function "Automatic" in the SPS-control of the installation clamp VM, the single operating
steps (of the duty cycles of the HVZ-UNI-II) will be activated automatic one after the other (see operating manual
Installation Machine VM).
