Troubleshooting
If the Blast Machine does not function properly, check the following:
SYMPTOM
(Cause)
ACTION
2.0 Cubic Foot L-Series Blast Machine
Insufficient air supply. Ensure air compressor
provides sufficient air volume to operate Blast
Machine and the Air Hose is of sufficient size to
provide adequate air volume.
Filler Plug or Filler Plug O-ring damaged. Inspect
Filler Plug and Filler Plug O-ring for wear or damage.
Replace damaged Filler Plug O-ring. If Filler Plug is
damaged remove blast machine from service.
Filler Plug not seated. Ensure Filler Plug is in proper
position and a proper seal has been achieved.
External Piping is damaged or loose. Inspect
external piping for damage. Confirm all fittings are
tight and free from damage.
With Blast Machine pressurized, close Choke Valve
to "Purge" and clear minor obstruction in Bantam
Metering Valve, Blast Hose or Nozzle.
Depressurize Blast Machine. Inspect Blast
Nozzle, optional KwikFire 153, and Blast Hose for
obstruction. Never look directly down the exit port
of the Blast Nozzle. Remove obstruction.
Damp or wet media. Remove all media from Blast
Machine and Metering Valve. Ensure dry media is
used.
Slightly open optional Moisture Separator Petcock
to allow collected moisture to escape while Blast
Machine is in use.
Consult Ceramic Nozzles Chart (Fig. 8) for compatible
media and nozzle selection.
Refer to Bantam Metering Valve and/or KwikFire 153
Operator's Manual for proper instructions.
Always depressurize the entire
blasting system, disconnect all
electrical power sources and
lockout/tagout all components
before any maintenance or
troubleshooting is attempted.
Failure to comply with the above
warning could cause electrical
shock and inadvertent activation
of equipment resulting in death
or serious injury.
Crushing and pinching are
normal functions of this
component. Do not place body
parts or foreign objects in any
area where there are moving
parts. Failure to comply with
the above caution may result in
minor or moderate injury.
Blast Machine will not pressurize
(Improper Air Supply, Damaged Components)
Neither air nor media exits the blast nozzle
(Obstructions, Wet Media, Metering Valve, Improperly
Sized Media, optional KwikFire 153)
Release of high speed media
and compressed air occurs
during depressurization of
the blast machine. Ensure
appropriate Personal Protective
Equipment is in use. Failure to
comply with the above caution
may result in minor or moderate
injury.
Moisture build-up occurs when
air is compressed. Any moisture
within the blast system will
cause media to clump, clogging
metering valves, hoses and
nozzles. Install an appropriately
sized moisture separator at
the inlet of the blast machine.
Leave the moisture separator
petcock slightly open to allow
for constant release of water. If
insufficient volume of air exists
and petcock is unable to be
left open (at all times) petcock
should be opened frequently to
release water.
