Repair. Repair Of the hose assembly is limited to replacement of defective parts. Disassemble and reassemble
hose assembly as follows:
(1) Cut the hose clamps and remove them from the hose.
(2) Remove the couplings from the hose. Remove gasket from inside the female coupling.
(3) Remove damaged section of hose. Ensure static wire extends 1/4 inch.

Insert the coupling shank into the hose. Be sure the static wire makes contact with the coupling.
Cut two bands from the 1/2-inch or 3/4-inch strapping roll which will encircle the hose and extend 8 to
10 inches beyond.
Position each band over hose and coupling so they are evenly spaced over coupling shank.
Hold the buckle with the prongs extending up and insert one end of the band through the toothed slot.
Hook the band over the top of the buckle between the prongs.
Bring the other end of the band around the hose and through the buckle.
Insert part of the band drawn through the buckle into the tool slots. The nose of the tool should be
flush against the buckle.
Apply tension on the tension handle, keeping tension on the band gripper lever, and adjust the
position of the tool as required. The lever will lock itself with the correct amount of tension.
