CAUTION:
Before installing a cylinder onto the

mechanism by pushing downwards and
toward the cylinder to close the
mechanism and tighten the cylinder band.
The clamp mechanism will lock

is unlocked and in the open position.
ii) Adjust the tension of the cylinder
band using the slide buckle.
iii) Close the clamp mechanism and
check that the cylinder is held securely.
