5.16 Vacuum Hose Replacement
& Rotation Procedure
Debris buildup, kinks, clogs or leaks in the system
will cause a reduction in airflow at the blasting
head, reducing the efficiency of operation or caus
-
ing operations to stop completely. Debris buildup
inside the hoses can be removed by periodically
tapping the outside walls with a dead blow ham-
mer 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 head and where the debris
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 water blasting system is shutdown
with the truck in the service position before rotat-
ing or replacing vacuum hoses.
NOTICE:
DAMAGED VACUUM HOSES CAN BE REPAIRED USING DUCT
TAPE AS A TEMPORARY SOLUTION TO EXTEND THE LIFE
OF THE VACUUM HOSE.
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.
