8. Troubleshooting
Problem Reason Solution
No Abrasive Flow Foreign material in the mixing
chamber assembly.
Remove nozzle and check for
blockage in the suction head
and nozzle.
Abrasive blockage in the
material hose. If the material
hose packs with abrasive, it is
a sign that the abrasive mixture
is too rich.
Make sure the air-intake holes
in the lance are open.
Worn nozzle. Replace nozzle when the
orifice is worn to 9/16", or
sooner if production decreases
noticeably.
Air jet worn. Inspect end of air jet and
replace when wear reaches the
orifice.
Air jet and/or nozzle not seated
correctly.
The jet and nozzle must be
fully seated into the mixing
chamber, and the setscrews
must be tight.
Abrasive bridging at the lance’s
abrasive inlet holes. Frequent
bridges or blockage are most
likely caused by damp abrasive.
Empty the material hose and
hopper of abrasive, and store
the abrasive in an airtight
container when not in use.
Hole worn in material hose. Inspect hose for holes and
inspect the clamps for leaks.
Repair as needed.
