Operation
19. Move the handgrip downwards (), to
achieve the desired working height.
21. Switch on the vacuum generation at the
pressure switch (at the blower unit) ().
23. Place the suction plate always completely on the
load (stone slab). Position the suction plate
always centrally on the load (stone slab) for a
uniform load balancing.
When the suction plate is positioned off center,
there is a risk (when lifting and lowering), that
the load suddenly may fall down. Caused by
uneven load balancing.
Watch the pressure gauge. Once a under
pressure of - 0.22 bar is reached, the load can be
lifted.
Never lift the load before lifting - the load would
fall down.

22. The suction of the load (stone slab) as well
as the release is done via the cable plug
(with integrated ON/OFF switch) on the
handle. ().
