9 Detach pneumatic pressure lines (1) from central reservoir (4) and close off openings with suitable stop plugs. NOTES
Do not stretch, crush or kink pneumatic pressure lines (1).
This will result in damage to pneumatic pressure lines (1) and can impair their function.
NOTES
The thread on the connection of the respective pneumatic pressure lines (1) and the pneumatic pressure lines (1) themselves must not be damaged.
Otherwise, leaks will occur.
