Bedienung generell

In principle, the control lever of the carrier (e.g. excavator) must be used for operation:
Always slowly return the control levers of the hydraulic valves on the carrier to the neutral 0 position,
never let the control lever "jump back" to the 0 position by simply releasing it! Otherwise uncontrollable
pressure overlaps may occur.

Start the hydraulic drive and switch on the warning device
Position the lifting device directly above the load. Do not pull to the side. Distribute load evenly.
Place the lifting device on the load.
Shift the bushing on the slide valve. Suction is applied to the load.
Watch the pressure gauge. As soon as a vacuum pressure of -0.6 bar has been reached you can lift
the load. Do not under any circumstances lift the load before the manometer has reached this
level as the load would fall off.
When lifting be sure to lift only one piece at a time. Use a screwdriver to carefully remove any
pieces attached to the one you are lifting before proceeding. Do not separate them with your
hands as they could be crushed!
Lift the device with the sucked load just a little (approx. 20-30 cm), then remove the load-securing
chain (8) from the chain case (9) and throw it under the lifted load.
Never grip with the hands under the load (stone slab) – danger of squeezing the hands!
Suspend and tighten the load-securing chain (1) on the other side of the device (place the end of
the chain into the chain case (9).
The load-securing chain must fit tightly to the load (see F ig. A), so that load with vacuum failure
(e.g. due to power / vacuum failure) is held by the security chain.
The safety chain must NEVER hang loose under the load, otherwise load may fall down, in a
vacuum load failure (e.g. due to power failure).Danger to life!
Now the device with sucked load be transported to the destination.
Lower the load carefully (distance to the ground approx. 20-30 cm), then remove safety chain and
throw it under the load.
Never grip with the hands under load (stone slab)! Danger of squeezing!
Load-securing chain (8) should be returned to chain case (9).
Place the device with the sucked load completely on the floor.
Once the load has been held by the load securing chain, the load securing chain must be properly
tested and replaced if necessary. Damaged load-securing chains must not be used any further!!
