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 operating instructions.
5. Elimination of defects
If a safety valve blows-off too early because a foreign body has
penetrated and is lodged in, then the blow-off device is to be ope-
ned 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.
