Put the tube end onto the hole bottom of
the temporary tightening tool and tighten
the nut slowly to the point where the tube
can no longer be rotated by hand. This
point is called the "zero point."

Matchmarking the zero point and further
tightening the nut will cause the sleeve to
bite into the tube.
At this time, check the shape of the sleeve
using the following illustration as a guide,
and adjust the numbers of turns for
tightening the nut.
Sleeve A: short with no slit - tighten 3/4 turn
Sleeve B: long with slit - tighten 1 + 1/4 turn

end is a few millimeters apart from the tube
end and that the sleeve will not move in the
axial direction (it is allowed to move in the
circumferential direction).
