Operation / load handling
•
The lifting time to ventilation time (release) should be about 2/3 to 1/3.
•
Maximum lifting time 2 minutes, followed by 1 minute of free suction (without load).
•
DO NOT place the vacuum lifting device with the vacuum generator running on an airtight surface
(plate), as this may cause the vacuum generator to overheat.
•
Switch off the vacuum generator if there are breaks in operation of more than two minutes.
•
The power supply or the external power connection must always be within sight of the device
operator
•
Select an appropriately sized suction plate that fits the load to be lifted and moved.
•
Position the suction plate at the centre of gravity of the load (does not always have to be the centre of the load).
•
Bring a little pressure down to the carrying handle ( ) and press lightly on the ventilation flap ( ) with your thumb
for the suction process (Fig. 7).
•
Place one foot on the load to be lifted and at the same time pull upwards on the carry handle to make sure that the
required working vacuum has been reached.
•
Lift the load a little while holding the hand carry handle vertically. Shake vigorously to test the lifting capacity before
use.
•
Carefully transport the load and place it in the desired position (Fig. 11 / Fig. 12).
To release the load, lift the ventilation flap slightly with your thumb (Fig. 8 / Fig. 9).
•
If a load needs to be lifted from higher stacks or pallets, it is recommended to reduce the height of the height-
adjustable carry handle and
(Fig. 10). It may be necessary to turn the carrying handle 90° for more ergonomic handling or to be able to transport
rectangular loads more safely.
