Manual No. 23350, Rev G, 02/19
8.11.5
Pressure regulator may be set too low or OFF.
Adjust blast pressure, per Section 5.1.
8.11.6
Make sure that 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 the foot pedal is
released
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 2.5.1 and 2.5.2.
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(s) clogged. Refer
to the dust-collector owner’s manual noted in Section
1.1.1.
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 and route them with as few bends as possible
to prevent early wear.
8.13.5
Reclaimer door open. DO NOT operate unless
door is closed.
8.13.6
Obstruction 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. Refer to Sections 2.2.1 and 2.4. 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 buildup 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
Damaged door gaskets. Inspect and replace
damaged gaskets.
8.15.2
Refer to Section 8.13.
8.16
Dust leaking from dust collector
8.16.1
Damaged or loose filter cartridge(s). Inspect
filters, replace as needed.
8.16.2
Cartridge(s) not seasoned; refer to the dust-
collector owner’s manual.
8.16.3
Refer to the dust-collector owner’s manual
