HOSE REMOVAL AND INSTALLATION
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.)
HOSE CLAMPING
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.
