Changing the O-rings in the sensor unit
When during the tension rise the values of
a tensio shaft flatten significantly or even
drop before reaching the vacuum (at
about 800 hPa or 80 kPa) this indicates
a leakage. In this case change the red
O-rings in the sensor unit.
Use fine pointed tweezers to pierce the
O-ring and pick it.
Take the spare O-rom from the service
pack. Do not pierce it.
Put O-ring into the hole and let it "snap"
into the groove on the bottom.
If the O-ring does not snap in itself screw
in the tensio shaft cautiously.
