Manual No. 30421
8.9.2
Check for blockage in media hose. Refer to
Section 8.7.
8.9.3
Poor suction in media hose. Refer to Section 8.8.
8.9.4
Make sure the air hose and media hose are not
reversed on the BNP gun. The green air hose attaches
to the back of the gun, and the clear media hose
attaches to the bottom of the gun’s grip. Refer to Page
51, Figure 65.
8.10
Blowback 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
cfm table in Paragraph 1.12.1, Figure 4.
8.11
Blasting does not begin when the foot pedal
is pressed.
8.11.1
Blast-pressure regulator may be set to low or to
OFF. Adjust blast pressure, per Section 5.1.
8.11.2
Make sure the air compressor is operating and
air-supply valves are open.
8.11.3
Check the nozzle to see if it is plugged. Refer
to Section 8.4.
8.11.4
Cabinet door interlocks not engaging. Check
adjustment, per Section 5.6.
NOTE: The green start-
button light stays lit if either of the two door
interlocks are not engaged.
8.11.5
Dustbin
interlock
not
engaging.
Check
adjustment, per Section 5.7.
NOTE: The green start-
button light remains off when the dustbin interlock
is not engaged.
8.11.6
Blocked or leaking control lines. Check all
urethane tubing for blockage or leaks.
8.11.7
Electrical malfunction. Refer to Section 9.4.
8.12
Blasting continues after releasing foot pedal
8.12.1
Foot pedal or another electrical malfunction.
Check per Section 9.5.
8.12.2
Inlet regulator stuck open. Inspect inlet
regulator.
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 results
in media carryover 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 stowed in the
electrical control panel.
8.13.2
Dust-collector exhaust damper closed too far,
restricting air movement through the cabinet. Adjust
static pressure, per Section 5.4.
8.13.3
Dust-collector filter cartridge clogged. Refer to
Section 5.8 to adjust pulse pressure; refer to Section
6.7 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 2.4. 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 could build up in the part if it is 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.
