Positioning the packer & sleeve
Positioning the packer with the QuickLock sleeve over the center of the damaged area can be done by
three different ways:
1) By sight
Position the sleeve using only the image from the camera.
2) By measuring
Use the tractor’s distance counter to measure the distance.
Or use other reliably means.
Position the middle of the sleeve over the center of the
damaged area.
3) By laser (preferable)
Align the sleeve with the laser on the front of the packer
beforehand.
(1) Position the laser on the center of the damage.
(2) Move the packer forward by half the length of the sleeve.

Positioning Pressure
Caution Notes for Positioning Pressure:
For longitudinal cracks and fragmentation, particularly in glazed clay pipes, do not expand the
packer outside the sleeve, because this can damage the host pipe.
When expanding, make sure the sleeve opens easily. The sleeve opens more easily if the metal
overlap is lubricated.
Particularly in 18”-32” pipes
, the sleeve needs plenty of time to open the full distance. Increase
the pressure to the sleeve in stages and let is expand to the fullest extent for each stage.
If you notice that the sleeve is obstructed or not opening smoothly, reduce the application
pressure and reposition the packer so that the middle of the balloon is in line with the middle of
the sleeve.
If the sleeve is expanding eccentrically (off center), it can produce torsion which may damage the
locking gear or the toothed strips.
Start pressing the QuickLock sleeve to the wall of the pipe with a
positioning (or set) pressure
of approximately 29 - 36 psi. Do not
inflate to installation pressure so that you can reposition the packer.
