8.10
Blow-back through media hose
8.10.1
Blockage in nozzle. Remove the nozzle and
check for blockage.
8.10.2
Air jet may be too large for nozzle. Refer to the
table in Figure 2.
8.11
Blasting does not begin when the foot pedal
is pressed.
8.11.1
Door
interlocks
not
engaging.
Check
adjustment, per Section 5.5.
8.11.2
Blocked or leaking control lines. Check all
urethane tubing for blockage or leaks.
8.11.3
Foot pedal valve malfunction. Check foot pedal
alignment, and inlet and outlet lines for pressure.
8.11.4
Make sure lines are not reversed on the foot
pedal or pilot regulator. Refer to the cabinet controls and
plumbing schematic on Page 33, Figure 44.
8.11.5
Pressure regulator may be set to low or OFF.
Adjust blast pressure, per Section 5.1.
8.11.6
Make sure the air compressor is operating and
air-supply valves are open.
8.11.7
Check the nozzle to see if it is plugged. Refer to
Section 8.4.
8.12
Blasting continues after releasing foot pedal
8.12.1
Make sure the 3-way valve in the foot pedal
exhausts air when the pedal is released. If it does not
exhaust, check the inbound air line for blockage, if no
blockage, replace the valve.
8.13
Media buildup in cabinet hopper; media does
not convey to reclaimer
NOTE: Do not pour media directly into the cabinet
hopper, as overfilling may occur.
Overfilling will result
in media carry over to the dust collector and possible
blockage in the conveying hose.
8.13.1
Exhauster motor rotating backward. The motor
should rotate as indicated by the arrow on the exhauster
housing. If it does not rotate in the proper direction,
lockout
and
tagout
electrical power and switch the motor
leads, as shown on the motor plate. Refer to the system’s
wiring schematic. Refer to Sections 2.4.
8.13.2
Dust-collector damper closed too far, restricting
air movement through cabinet. Adjust static pressure,
per Section 5.4.
8.13.3
Dust-collector filter cartridge clogged. Refer to
Section 5.6 to adjust pulse pressure; refer to Section
6.2.4 for additional cartridge pulsing.
8.13.4
Hole worn in flex hose between cabinet hopper
and reclaimer inlet or between the reclaimer outlet and
dust-collector inlet. Inspect hoses and replace them as
needed.
8.13.5
Reclaimer door open. DO NOT operate unless
door is closed.
8.13.6
Obstruction in flex hose. Remove hoses and
check for blockage.
8.14
Static shocks
8.14.1
Cabinet and/or operator not grounded. Abrasive
blasting generates static electricity. The cabinet must be
earth-grounded to prevent static buildup. See Section
2.3. If shocks persist, the operator may be building up
static. Attach a small ground wire, such as a wrist strap,
from the operator to the cabinet.
8.14.2
Gloves wearing thin. Inspect gloves and replace
them as needed.
8.14.3
Avoid holding parts and blasting off the grate.
Static will build in the part if not dissipated through the
metal cabinet. If blasting parts off the grate cannot be
avoided, attach a ground wire between the cabinet and
the part.
8.15
Dust leaking from cabinet
8.15.1
Refer to Section 8.13.
8.16
Dust leaking from dust collector
8.16.1
Cartridge not seasoned; season cartridge, per
Section 7.10.
8.16.2
Damaged or loose cartridge. Inspect filter
cartridge and tighten or replace as needed.
8.16.3
Faulty seal on the dust collector cone. Inspect
seal and replace if damaged.
