3.2.2 Preparing gas pressure spring for disposal
WARNING!
Risk of injury due to high pressure
The gas is the gas pressure is highly pressurised. There is a
risk of injury due to flying metal fragments and oil, if dis-
posal is not carried out properly. Observe following safety
measures implicitly for proper draining.
Before disassembling:
– No person in the extended axis of the device. The piston
rod cannot hit anyone in the case of an error.
– Do not remove the ends.
– Under no circumstances use a lathe.

The gas itself is harmless.
Handling
Viega Gas Pressure Spring 8 from 10

The container needs to be drilled at two points to enable the disposal of
the gas pressure spring without pressure and without oil. The drilling
points X1 and X2 vary depending on the diameter of piston rod and cyl-
inder.
Diameter (mm) piston rod / cylinder X1 (mm) X2 (mm)
8/19; 8/22; 10/22 20 30
8/28; 10/28; 14/28 40 35
10/40; 14/40 40 55
Open up gas pressure spring.
DANGER! Protect eyes, face and body and cover drill hole
before drilling.
Fig. 1: draining gas and oil
Using a 2–3 mm drill, drill slowly at point X1 until gas escapes.
ðDue to the high internal pressure, metal fragments and oil can
squirt out.
Using a 2–3 mm drill, drill slowly at point X2 until pressure drops and
oil becomes accessible.
Pour out the oil into a suitable container.
