12.1 Disposal of the gas pressure spring
The filling medium used [nitrogen] is a natural component of
ambient air. The loss of pressure is therefore harmless.
Most of the remaining components of the gas pressure
spring are made of steel and these can be sent for recycling.
The oil used is governed by legislation for the processing of
special-category waste and can only be disposed of by au-
thorized waste disposal specialists.
INFORMATION
Gas pressure springs are filled with a pressure of be-
tween 20 and 250 bar and must be degasified prior to
disposal.
WARNING
Serious injuries caused by projectile oil and swarf
from the sawing point with high internal pressure!
Wear personal protective equipment
Use appropriate hand saw.
Place protective cloths around the sawblade.
Stop sawing as soon as gas starts to escape.
No-one in the area of the extended pressure pipe
axis.
For safety reasons, proceed as follows:
Clamp the pressure tube in a vise without distorting it.
Saw the pressure pipe crosswise in a range of 40-
45 mm above the pressure floor.
The gas pressure spring is not fully depressurized until
the piston rod can be moved freely by hand.
Pump oil into an appropriate receptacle by moving the
piston rod up and down several times.
