Benchtop Blast Cabinet
Description
Maxus Benchtop Blast Cabinet is
designed for cleaning and removing
rust, scale, and paint. It is the ideal
method for stripping, polishing and
etching projects. A blast cabinet keeps
sandblasting particles in a contained
area and allows them to be recycled.
The cabinet also confines dust particles
and a vacuum hook-up can remove any
dust that occurs during sandblasting.
Safety Guidelines
This manual contains information that is
very important to know and understand.
This information is provided for SAFETY
and to PREVENT EQUIPMENT PROBLEMS.
To help recognize this information,
observe the following symbols.
Danger indicates an
imminently
hazardous situation which, if not avoided,
will result in death or serious injury.
Warning indicates a
potentially
hazardous situation which, if not avoided,
could result in death or serious injury.
Caution indicates a
potentially
hazardous situation which, if not avoided,
may result in minor or moderate injury.
Notice indicates
important
information, that if not followed, may
cause damage to equipment.
Unpacking
After unpacking, carefully inspect for
any damage that may have occurred
during transit. Check for loose, missing
or damaged parts.
General Safety
Information
CALIFORNIA PROPOSITION 65
You can
create
dust when you sweep, blast,
cut, sand, drill or grind
materials such as wood, paint,
metal, concrete, cement, or other
masonry. This dust often contains
chemicals known to cause cancer, birth
defects, or other reproductive harm.
Wear protective gear.
This product or its
power cord contains
chemicals, including lead, known to the
State of California to cause cancer and
birth defects or other reproductive
harm. Wash hands after handling.
SILICA ABRASIVE HAZARD
Breathing
dust from abrasives
containing silica can be dangerous.
Exposure can cause SILICOSIS, lung
disease, or other respiratory problems,
Wear NIOSH/MSHA approved respirator
at all times when performing abrasive
blasting and while cleaning up.
Fire or
Explosion
Hazard!Never use a sand
blaster around combustible or
flammable liquids, gases,
dusts, oily rags, or other
materials that can explode or
burn quickly. Some abrasives
create sparks when they hit
metal. Abrasives similar to aluminum
oxide may generate static electric
sparks. In an unsafe environment, these
sparks will start fires or explosions that
will result in death or serious personal
injury. For your safety and the safety of
people nearby, DO NOT USE this sand
blaster where there are combustible or
flammable liquids, gases, dusts, oily
rags, or other materials that can
explode or burn quickly.
Model MXS3000
Static
electric
shocks can be painful. Some
abrasives similar to aluminum
oxide can create static
electricity while you are sand blasting.
If you are not grounded, the static
electricity can build up on your body
and cause a shock when you touch a
metal object. You can avoid static
electricity by wearing leather soled
shoes and standing on the ground. If
necessary, a grounded wire attached to
the sand blast gun will safely remove

Maintenance
Cleaning
The plastic door cover should be
cleaned with a soft damp cloth. NEVER
use solvents to clean plastic parts. They
could dissolve or otherwise damage
the material.
Changing the Ceramic Gun Nozzle
The blast cabinet is equipped with a
ceramic nozzle that controls the flow
of abrasive media as it exits the spray
gun. The nozzle creates a smaller
opening for the media to exit which
gives a finer spray that easier to
control. Replacements for the ceramic
nozzle are included. To replace a
nozzle, unscrew the outer metal
covering of the nozzle and remove the
old ceramic nozzle. Insert the new
nozzle and reattach the metal cover.
Draining Abrasive Material
The blast cabinet is equipped with a
drain for easy clean up of abrasive
materials. The floor of the blast
cabinet tapers toward the center,
where the drain is located.
In order to remove blast media:
1. Make sure the air supply is
disconnected before doing any
draining.
2. Secure the cabinet in an elevated
position that allows room for a
container below the plug.
3. Place a container within 4 inches of
the drain opening.
4. Pull the plug from the drain and
allow media to drain from cabinet.
DO NOT shake cabinet. Shaking the
cabinet could cause the media to
spill and create dust that could be
hazardous if breathed.
You can create dust
when abrasive media
is poured into or drained from the blast
cabinet. Wear a mask and eye protection
when draining the blasting media.
5. Any excess media can be moved
toward the drain with a brush.
DO NOT use the blasting gun to
blow air to drain the abrasive media.
Doing so can create dust that could
be hazardous if breathed.
Storage
1. Turn ON / OFF switch to the OFF
position.
2. Unplug power cord from outlet.
3. Disconnect the air supply from the
blasting cabinet
4. Remove the abrasive media from
the cabinet using the drain.
5. Store in a cool, dry place.
Service
Tool service must
be performed only
by qualified repair personnel and by an
AUTHORIZED SERVICE CENTER. Service or
maintenance performed by unqualified
personnel could result in a risk of injury.

Abrasive Blasting
Media
Blasting media comes in many different
grit sizes and sometimes is also rated as
extra fine, fine, medium, coarse, and
extra coarse. The larger the grit
number, the smaller the particle size;
the smaller the grit number, the larger
the particle size. Glass media can come
in beads, crushed, or ground.
Aluminum oxide and silicon carbide can
come in several colors. It is common
today to find mixtures of glass and
aluminum oxide.
Abrasive Media - Not
Recommended
Although available, some media are
not recommended for use because of
echanical and/or personal hazards.
m
Silica sand, a common blast media, has
health risk concerns due to the silica
ontent. Restriction on its usage is
c
common in many states.
each sand (play sand) is a common
B
and inexpensive blast media. This
highly aggressive media can have
debris mixed in which will cause
clogging of equipment.
Steel grit produces ideal surface
preparation on new coating. This
media should only be used in a special
blast cabinet designed for this media.
Steel shot, a round, solid particle,
leaves a dimples in a surface after
blasting. It is a very dense media and
should only be used in a special blast
cabinet designed for this media.
Common Abrasive
Media
The more commonly available media
and their uses are listed below.
Walnut shell is one of the most
versatile organic media due to its
angular, durable shape. It is still
considered a soft media, but it is good
to use on delicate parts. Use as an
economical, bio-degradable alternative
for sensitive blasting that will not
scratch or damage surfaces.
Glass beads are the most popular allpurpose media used today. Used for
honing, polishing, peening, blending,
finishing, removing light burrs, frosting
glass, and cleaning most light materials.
Common uses in the removal of paint,
rust, and surface residues. Glass bead
blasting generally will not change the
dimensions of the item being blasted.
Glass beads produce brighter finish than
angular abrasives. Beads can be recycled
and used many times.

MXS3000
Common Abrasive
Media
Crushed glass is very aggressive. Used
for economical, general clean-up.
Plastic is available in a variety of sizes
and materials (urea, acrylic, polyester,
nd melamine). These materials are
a
ideal for application such as auto
restoration to deliver a high stripping
ate without damaging or warping the
r
substrate material.
Brown aluminum oxide is a widely used
abrasive media. This media produces a
extured surface, good for repairing
t
surfaces for recoating. It is excellent for
removing heavy foreign materials,
eburring, and etching glass and stone.
d
It is a fast-cutting media that can be
reused many times.
White aluminum oxide can be used in
the same applications as the brown
luminum oxide, but white aluminum
a
oxide is considered to be a clean media,
used in high performance processes
where contamination of metal oxide
must be kept to a minimum.
Moisture in the air when compressed will create water in the compressor tank. When humidity is high or when a compressor is in
continuous use for an extended period of time, moisture will collect in the tank. When blasting, this water will be carried from
the tank through the hose and will be mixed with the abrasive media.
IMPORTANT: THIS MIXING
OF WATER AND ABRASIVE MATERIAL WILL CLOG THE SYSTEM. THE BLASTER WILL NOT OPERATE.
A compressed air dryer and/or water separator will help eliminate this problem.
