Open the handwheel (3) on
the Vetter pressure regula-
tor.
Open the ball valve (6) to
inflate the Lifting Bag and
raise the load.
Keep an eye on the internal
pressures in the bag shown
at the mano-meter (8) of
the dual controller and the
load. The safety valve
prevents an overfilling of the
bag.
Depending on the type,
position and behaviour of
the load during lifting, the
Lifting Bags are filled either
•
simultaneously and
equally or
•
gradually and / or
individually.
Close the ball valve imme-
diately in the event of a stop
or fault, find the cause and
remedy.
The max. tolerance for
opening and closing the
safety valve may be
± 10 %. The manometer (8)
shows the pressure in the
bag.
Open the discharge device
on the head of the safety
valve (7) by turning anti-
clockwise to deflate the
Lifting Bag and / or lower
the load.
