If a siezed Drawtube us suspected then proceed to remove the damper as described in the
next section and, with the Damper removed, establish whether the Drawtube can be made to

damping function and must be replaced.
•
If the Coupling Head extends very slowly or only partially then the Damper has lost most of its
gas pressure and must be replaced.
