Replacing The Operating Diaphragm - Samson 2417 Series Mounting And Operating Instructions

Servicing
7.4 Replacing the operating
diaphragm
NOTICE
!
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.
Note
SAMSON's After-sales Service department
can support you concerning lubricant,
tightening torques and tools approved by
SAMSON.
