6.7 Setting the hovering position
Flex 20/35
Flex 50
Turning the knurled nut (2) clockwise also reduces the flow rate to the suction
pads. If the flow rate is reduced too much, it will become difficult to lift porous
loads. The adjustment range of the hovering position depends on the vacuum
pump employed.
6.8 Raising, lowering and depositing loads
Always carry the load in front of you, ensure you have a clear path, and avoid any trip hazards.
Always transport loads as close to the ground as possible and adapt the transport speed to the
working conditions.
The hovering position without load must be set before start of operations (see section 6.6 “Setting the
hovering position”).
The lifting operation is controlled using the actuating lever (1/2), which has 2 pressure points.
1. Lowering the load
2. Releasing & removing/ejecting the load
Pressing the actuating lever (1) towards the device opens the air escape
valve and the
J
UMBO
is lowered.
When the actuating lever (1) is released, the device returns to its initial
position and the tube lifter returns to the suspension position. The initial
position is always at the top.
The device can be lowered below the set hovering position by pressing
down lightly on the actuating lever (1) with your index finger until the
pressure point (1/2) is reached.
Pressing down on the lever up to the pressure point (1/2) actuates the lift
tube’s lifting stroke.
Pressing beyond the pressure point (1/2), deposits/releases the load.
The working height of the operator handle
– without load – can be
adjusted to a more ergonomic height as desired. The working height is
adjusted by rotating the knurled nuts (2)
– this adjusts the idle position
of the valve.
