Cleaning And Replacing The Plug - Samson 46-5 Mounting And Operating Instructions

Servicing
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 tightening torques specified in
section 7.3.
Note
The regulator was checked by SAMSON be-
fore it left the factory.
− The product warranty becomes void if ser-
vice or repair work not described in these
instructions is performed without prior
agreement by SAMSON's After-sales Ser-
vice department.
− Only use original spare parts by
SAMSON, which comply with the original
specifications.
