5.14 Vacuum Hose Replacement
& Rotation Procedure
Debris buildup, kinks, clogs or leaks in the system
will cause a reduction in airflow at the blasting
heads, reducing the efficiency of operation or
causing operations to stop completely. Debris
buildup inside the hoses can be removed by pe-
riodically tapping the outside walls with a dead
blow hammer while the system is operating at
maximum vacuum. This will flex the hose walls and
cause built up debris to break off and be sucked
into the debris tank.
The internal walls of vacuum hoses develop wear
points caused from the high velocity of abrasive
debris traveling inside the hoses. The wear points
are most prevalent in the outside radius of tight
bends near the blasting heads and where the de-
bris hose rises above the truck cab.
The life of the hoses in these areas can be ex-
tended by rotating the hoses 120
0
every 200
hours. Vacuum hoses should be inspected daily
and replaced as needed.
Make sure the waterblasting system is shutdown
with the truck in the service position before rotat-
ing or replacing vacuum hoses.

Vacuum Hose Replacement
1. Release the cam locks at the hose connection
fittings.
2. Remove the old vacuum hose assembly.
3.
If the cam lock fittings are in good condition
and can be reused, cut the old hose off of the
fittings. Then install the fittings in the new
vacuum hose.
4. Connect the new vacuum hose assembly and
close the cam locks.
Vacuum Hose Rotation
1. Mark the position of the hose, then release the
cam locks at the hose fittings.
2. Using the marks as a reference, rotate the
hose 120 degrees.
3. Secure the hose in the new position with the
cam locks.
