6.5.1 Reclaimer wear plate and liners:
Remove the
flex hose from the reclaimer inlet and use a light to

SERVICE MAINTENANCE
WARNING
Prior to doing any maintenance or opening the
dust collector, the employer must meet
required OSHA standards including but not
limited to 29CFR 1910 for
Appropriate Respirator
Protective Clothing
Toxic and Hazardous Substances
Fall Protection
Lockout and Tagout Procedure
All dust is hazardous to breath;
toxicity and
health risk vary with type of dust generated by
blasting. Prolonged exposure to any dust can
result in serious lung disease and death. Short-
term exposure to toxic materials, such as lead
dust or dust from other heavy metals and
corrosives, can cause serious injury or death.
Identify all material that is being removed by
blasting and obtain a safety data sheet (SDS)
for the blast media. Waste dust in the collector
can cause serious injury or death through
inhalation, absorption, or ingestion. The
employer shall meet all OSHA requirements,
including but not limited to those for confined
space, combustible dust, fall protection, hazard
communication, and lockout and tagout
procedure for electrical and pneumatic supply.
7.1
Gloves
7.1.1
Special static-dissipating gloves are provided for
operator comfort. It will be necessary to change gloves
periodically as they wear. The first sign of deterioration
may be excessive static shocks.
7.1.2
Band-clamp type:
Band-clamp type gloves are
held in place by metal band clamps on the inside of the
cabinet. To replace, loosen the clamps with a
screwdriver, replace the gloves, and tighten the clamps.
7.1.3
Quick-change type, clampless installation:
Quick-change gloves are held in place using spring rings
sewn into the attachment end of the glove. To install,
insert the glove into the arm port so one spring is on the
inside of the port and the other is on the outside,
sandwiching the arm port between both spring rings.

7.2.1
Replace the nozzle when its orifice diameter has
worn 1/16" larger than its original size or when suction
diminishes noticeably. To change the nozzle, unscrew
the holding nut from the gun end and pull the nozzle
from the gun. Inspect the nozzle O-ring and replace if
worn or damaged. Inspect the air jet cover; replacing it
before it wears through will prolong the life of the jet.
Insert a new O-ring and nozzle, placing the tapered end
toward the jet. Screw the holding nut onto the gun.
7.3
View-Window Cover Lens
7.3.1
Rapid frosting of the view window can be
avoided by directing ricocheting media away from the
window and by installing a cover lens on the inside
surface of the window. Using cover lenses prolongs the
life of the view window.
7.3.2
The best way to install a cover lens is to remove
the window from the cabinet. If, for some reason, it is not
practical to remove the window, the lens may be applied
with the window glass in place.
7.3.3
To install a cover lens, carefully remove the
adhesive backing making sure the adhesive remains on
the lens and apply the lens to the clean, dry, inner
surface of the view window. When the cover lens
becomes pitted or frosted, replace it.
The wider, tapered end of the
nozzle inserts into the gun.
