Manual No. 21527, Rev. I, 02/19

8.5.4

Absorption. Some media absorbs moisture from

the air, especially fine-mesh media in areas of high
humidity. Store media in an airtight container when
cabinet is not in use.

8.5.5

A vibrator mounted either on the blast machine

leg or on a bolt on the media metering valve may help to
prevent bridging of fine-mesh media.

NOTE: To avoid

the possibility of compressing media, a vibrator
should be set up to start when the foot pedal is
pressed and stop when the pedal is released.

8.6

Media surge:

A small amount of surge is normal

at start-up.

8.6.1

Heavy media flow. Adjust media flow, per

Section 5.2.

8.6.2

Empty the blast machine, depressurize the blast

machine, and inspect the internal parts of the metering
valve for wear. Refer to the Sentinel Media Metering
Valve Manual, number 20951.

8.7

Air only (no media) comes out the nozzle

8.7.1

Make sure the machine contains media.

8.7.2

Make sure the metering valve is open and

media flow is adjusted, per Section 5.2.

8.7.3

Make sure the blast machine is pressurized.

See Section 8.9.

8.7.4

Check for minor blockage in the media metering

valve by fully opening the metering valve and closing the
choke  valve.  Activate  the  foot  pedal  to  blow  out
obstructions.  If  this  procedure  fails,  depressurize  the
machine,  remove  the  metering-valve  inspection  plate,
and check for foreign objects.

8.7.5

Check the muffler on the 4-way air valve. Air

should exhaust from the muffler when the foot pedal is
released. If air does not exhaust, remove the muffler and
try again. If air exhausts now, the muffler is blocked. If
air still does not exhaust, the 4-way valve may be faulty;
refer to Paragraph 8.7.6 to check the 4-way valve.

8.7.6

Check the 4-way valve as follows: Depressurize

the air-supply line. Remove the tubing leading to either the
media  metering  valve  or  diaphragm  outlet  valve.
Pressurize the air-supply line. Air should not exhaust from
the  tube  adaptors.  Press  the  foot  pedal;  air  should
exhaust  at  the  tube  adaptor.  Release  the  foot  pedal;  air
should  stop  exhausting  from  the  tube  adaptors.  If  it
operates accordingly, the metering valve requires service.
If it does not operate accordingly, replace the 4-way valve.

8.7.7

Outlet valve not sealing. Inspect diaphragm.

8.7.8

Metering valve requires service. Refer to the

media metering valve manual.

8.8

Neither media nor air comes out the nozzle

when the foot pedal is pressed

8.8.1

Depressurize the blast machine and check the

nozzle to see if it is plugged.

8.8.2

Make sure the blast machine pressurizes when

the foot pedal is pressed. If it does not pressurize, refer
to Section 8.9.

8.8.3

Make sure the media metering valve and the

choke valve are open.

8.9

Blast machine does not pressurize

8.9.1

Make sure the compressor is operating and air-

supply valve is open.

8.9.2

Make sure the blast pressure regulator is not

set too low or OFF; minimum pressure is 40 psi. Refer
to Section 5.1.

8.9.3

Door

interlocks

not

engaging.

Check

adjustment, per Section 5.4.

8.9.4

Inadequate air supply. Refer to the cfm-

consumption table in Figure 3.

8.9.5

Inspect the diaphragm in outlet valve for wear.

8.9.6

Inspect pop-up valve and seal for wear and

misalignment.

8.9.7

Blocked or leaking control lines. Check all

urethane tubing for blockage or leaks.

8.9.8

Foot-pedal valve malfunction. Check foot-pedal

alignment, and inlet and outlet lines for pressure.

8.9.9

Make sure lines are not reversed on the foot

pedal or pilot regulator. Refer to the plumbing and control
line schematic in Figure 47.

8.9.10

Check the 4-way valve for jamming, per

Sections 8.7.5 and 8.7.6. When the foot pedal is
pressed, the valve should shift, pressurizing the line to
the outlet valve and media metering valve.

8.9.11

Inspect the check valve, Figure 48, Item 18) for

obstruction or broken flap.
