7.2 Replacing the set point
springs
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the specified tightening torques.
Make absolutely sure that no torque is ap-
plied to the bellows seal (5.1) during assem
-
bly or disassembly. Otherwise, the metal
bellows will be destroyed.
SAMSON's After-sales Service department
can support you concerning lubricant,
tightening torques and tools approved by
SAMSON.
