(2) When using hose clamps made from bulk hose clamp strapping, use clamping tool (Appendix C, Item 38) and
perform the following steps (a) through (h). (Refer to Figure 4-3.)
(a) Cut a length of strapping material from the 1/2 inch or 3/4 inch roll of bulk strapping material which will
encircle the hose and still have 8 to 10 inches more strapping material left over.
(b) Place two adjustable hose clamps and seals onto the end of the hose and insert the coupling half into the
end of the hose (Step 1). Insert the coupling shank into the hose. Be sure the static wire makes good contact with the
coupling half.
(c) Hold the buckle with the prongs extended up and insert one end of the strapping through the toothed slot.
Bend inserted end of strapping into a hook shape to fit over and under buckle.
(d) Pull on strapping until hook engages buckle (Step 1).
(e) Bring the other end of the strapping around the hose and through the toothed slot twice (Step 1).
(f) Insert part of the strapping drawn through the buckle into the tool slots. The nose of the tool should be
flush against the buckle (Step 2).
(g) Apply tension on the tension handle, keeping tension on the strapping gripper lever, and adjust the
position of the tool as required. The lever will lock itself with the correct amount of tension.
CAUTION
The hose strapping may break unless the operator releases tension correctly when
bending the strapping back over the buckle. Be sure that you gradually release the
tension on the strapping with the tension handle at the same time you are bending
back the strapping.
(h) Release the tension about one turn on the strapping while bending the strapping over the buckle teeth
(Step 3).
(i) Cut the strapping with the cutting handle (Step 4).
(j) Remove the tool and hold the stub of the strapping down with the thumb (Step 5).
(k) Clinch the strapping stub by hammering down the prongs of the buckle (Step 6).
(l) Repeat step (a) through (k) for each clamp.
