8.1 Cleaning and replacing the
seat and plug
DANGER
!
Risk of personal injury due to preloaded
springs.
Regulators in combination with preloaded
set point springs are under tension. These
regulators can be identified by the red warn-
ing label on the actuator's set point springs.
− Before starting any work on the springs,
relieve the compression from the preloaded
springs.
− Only use the SAMSON disassembly tool
(1280-4052).
NOTICE
!
Risk of regulator damage due to exces-
sively high or low tightening torques.
Observe the specified torques when tighten-
ing regulator components. Excessive tighten-
ing torques lead to parts wearing out more
quickly. Parts that are too loose may cause
leakage.
Observe the specified tightening torques.
NOTICE
!
Risk of damage to the facing of the seat
and plug due to incorrect service or repair.
Always replace both the seat and plug.
