4.3 Dismantling of the lifting bag system after use
Dismantling of the lifting bag system is carried out after ensuring
the lifted load and complete deflation of the lifting bag system,
including dismantling of all accessory parts in the reverse order.
4.4 Care and storage
The wedge lifting bag equipment is to be cleaned each time after
use. Normally cleaning is made with warm water and a soap de-
tergent.
A chemical cleaning agent is not to be used under
any circumstances and high pressure warm
water equipment is also never to be used.
Drying is made at room temperature.
DIN 7716 is to be observed with any long storage periods.
4.5 Repair instructions
Small cracks or cuts in the side wall material (max. 4 cm) can be
quickly repaired without difficulty using the supplied repair mate-
rial. See separat operting instructions.
5. Elimination of defects
If a safety valve of the controller blows-off too early because a
foreign body has penetrated and is lodged in, then the blow-off
device is to be opened at the head of the safety valve by turning
counter-clockwise so that the compressed air is able to escape.
If the foreign body is not removed, then the upper part of the val-
ve must be unscrewed with the safety valve disassembled. To do
this position the tube pliers in the centre and unscrew by turning
to the left. Carefully remove the valve ball and remove the foreign
body.
Screw the upper part of the valve tightly back and assemble the
safety valve, and check to make certain that it functions perfectly.
The set pressure must not be changed.
If the seal or seal plate has been removed on
the upper part of the valve then reliable
function is not guaranteed.
The safety valve is to be exchanged.
