7.0 TROUBLESHOOTING
WARNING
To avoid serious injury, observe the following
when troubleshooting.
• Turn off the air, and lock out and tag out the
air supply.
• If checking the controls requires air, always
enlist the aid of another person to:
Hold the blast gun securely.
Operate the foot pedal.
• Never bypass the foot pedal or wedge it in
the operating position.
7.1 Poor Visibility
7.1.1 Dirty filter. Clean filter, and empty dust collector
canister regularly.
7.1.2 Using friable media that rapidly breaks down, or
using media that is too fine or worn out.
7.1.3 Blocked air inlet duct. Blockage in the air intake
ducts restricts incoming air and reduces air movement in
the cabinet.
7.1.4 Hole worn in flex hose between cabinet back
and canister inlet.
7.1.5 Obstruction in flex hose between the cabinet
and canister inlet.
7.1.6 Paddle wheel worn. Check wheel for wear.
7.2 Abnormally High Media Consumption
7.2.1 Media may be too fine or worn-out.
7.2.2 Using friable media that rapidly breaks down.
7.2.3 Nozzle pressure too high for the media, causing
media to break down.
7.3 Reduction In Blast Cleaning Rate
7.3.1 Low media level reducing media flow. Check
and fill if low.
7.3.2 Incorrect metering valve adjustment. Adjust per
Section 4.3.
7.3.3 Reduced air pressure. This may be caused by a
malfunctioning regulator, a dirty filter element in the air
filter, partially closed air valve, leaking air line, or other
air tools in use.
7.3.4 Blockage in media line or gun. Blockage may
occur as a result of foreign material from the blasting
process, or incorrect metering valve adjustment
permitting heavy media flow. See Section 4.3.
7.3.5 Worn gun parts such as nozzle or air jet. Inspect
and replace all worn parts.
7.3.6 Worn media hose. Check hose for leaks and
soft spots. Replace worn or damaged hose.
7.3.7 Air jet in gun out of adjustment. Check
adjustment per Section 4.2.
7.3.8 Moist media. Frequent bridges or blockage in
the area of the metering valve can be caused by
moisture. See Section 7.5.
7.4 Plugged Nozzle
7.4.1 Foreign material in the nozzle. Clean and re-
install.
7.4.2 Media mixture too rich. Adjust media/air mixture
per Section 4.3.
