‹› Air spring dampers are supplied as replacement parts with a minimum pressure. By sitting in storage for extended periods this pressure can
diminish (just like a tire). This minimum pressure must be checked and if necessary restored by recharging before the air spring damper is
removed from the packaging. If the air spring damper is removed from the packaging without this checking/recharging, this may cause
indentations or kinks to form in the dust boot before it reaches its normal shape. These folds can cause damage and premature failure of the air
spring.
