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
warning 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 over- or
under-torquing.
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.
