To prevent damage to rubber hose, do not pry off rubber hose with tapered tool or screwdriver.
To reinstall the rubber hose securely, make sure that hose insertion length and orientation is correct. (If tube is equipped with hose stopper, insert rubber hose into tube until it butts up against hose stopper.)
If old rubber hose is re-used, install hose clamp in its original position (at the indentation where the old clamp was). If there is a trace of tube bulging left on the old rubber hose, align rubber hose at that position.
Discard old clamps; replace with new ones.
After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
