Operating Instructions
QJ 600-E
18. Move the handgrip downwards (),to
achieve the desired working height.
20. Switch on the vacuum generation at the
pressure switch (at the blower unit) ().
22. 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
