FEATURES
The 3 cu. ft. cabinet is lit by a low voltage (12 volt)
fluorescent tube. A transformer is provided which
should be plugged directly into the main supply. The
attached cable is then plugged into the switch box,
mounted on the left side of the cabinet. The switch box
contains the ON/OFF rocker switch.
We strongly recommend that this unit be used with a
vacuum extraction device. Air is extracted via a double
filtration system from the facility at the right hand side
of the cabinet.
Please note that when vacuum extraction is used,
air will be drawn into the cabinet through the hole on
the back panel of the unit. The hole is covered on the
outside with a filter plate, and housed within the plate
is a foam filter, which must always be in place. This
is to prevent grit from being blown out, if/when the
vacuum extraction is NOT used.
The lid is provided with a double clear plastic window,
the inner of which may be renewed quickly and easily if it
should become damaged by the sand blasting action.
A variety of abrasive nozzles is supplied with the unit
to produce a useful range of power and grit densities
to satisfy all requirements. The cabinet is designed
for use with dry abrasives ONLY. We recommend
Aluminium Oxide (for cleaning steel) and Glass Beads
(for cleaning Aluminium).
It is necessary to provide a clean, dry air supply,
capable of delivering a minimum of 10 cu. ft./min at
100 PSI. Please consult your air compressor manual,
ensuring you comply with all safety precautions
regarding the use of air compressors, and observe all
necessary precautions when using compressed air.
SAFETY PRECAUTIONS
• Ensure you comply with all precautions concerning
the use of air compressors and compressed air.
• Ensure all air connections are secure.
• Do Not use the machine if the rubber gloves are
ripped or otherwise unserviceable.
• Ensure the clear plastic lid is firmly secured before
pressing the trigger.
• Keep the jet well away from the air inlet hose (from
side panel to gun).
• ALWAYS wear safety glasses. (Normal eye glasses
are NOT safety glasses).
WARNING:This product can expose you to
chemicals, including DEHP and lead, which are
known to the State of California to cause cancer and
birth defects or other reproductive harm. For more

ASSEMBLY
Carefully unpack the unit, and check to ensure that no
damage was caused in transit. Should any damage
be apparent, please contact OEM at 1-866-458-2472
immediately. Remove all components from inside the
cabinet, and check them against the following list.
Fig. 1
Fig. 2
Fig. 3
Fig. 4
Fig. 5
The unit is shipped completely assembled, except
for the air vent filter and the gun with attached hoses.
These should be connected as follows: First, remove
the grid, and all the various components, from within
the cabinet. The end of the air inlet hose, connected to
the gun, is inserted through the 16mm dia. hole in the
cabinet, from the inside, as shown in Fig. 2. Ensure a
flat washer is threaded on to the adapter, as shown.
Thread a flat washer, followed by the extended
nut, on to the adapter, from the outside of the
cabinet, and tighten.
Connect the grit pick up hose to the pickup and
tighten the worm drive clip securely. Locate the
pick up on the floor of the cabinet. It is secured
with the two spring clips as shown in Fig 3.
Replace the grid, ensuring the feet face down-
wards with the cut away section at the right hand
rear of the cabinet. The pick up hose should be
routed through the gap made by the cut away por-
tion of the grid.
Insert the circular foam filter into the recess in the
Air Vent Cover, and attach the cover to the rear of
the cabinet as shown in Fig.4, having first pried
out the plastic bung from the vent hole.
Finally, connect the air supply to the extended nut
shown in Fig.5. Use of the PTFE tape supplied will
ensure an airtight seal.
The air supply should be dry, and capable of delivering
a minimum of 10 cu. ft./min at 100 PSI

NOTE:
Should it be necessary to change the Air Nozzle, first remove the abrasive nozzle as described above. A box
spanner will be required to unscrew and withdraw the air nozzle.
NOTES:
There are no hard or fast rules governing nozzle sizes and air pressures used with different abrasives. With expe-
rience and experimentation you will quickly learn the best combinations for the required result. On more delicate
parts, start with minimal air pressure to avoid unnecessary peening or excessive abrasion, and work up to a
setting to produce the desired finish. Should any abrasive be spilled, ensure it is cleaned up immediately, as its
slippery properties can be extremely hazardous.
REPLACING THE ABRASIVE NOZZLE
Ensure the air supply is disconnected before
performing this operation.
1. Pull the trigger of the gun as a precautionary
measure.
2. Unscrew the End Cap and withdraw the ceramic
nozzle.
3. Replace with the nozzle of your choice and carefully
thread the end cap back on to the gun, taking great
care NOT to cross thread the fine thread.
OPERATION
Plug the transformer into the power supply and switch
the power ON. Switch the lamp ON by pushing the
rocker switch on the switch box “I”. Switch OFF by
pushing “O”.
Ensure all air connections are secure, and the pick up
is correctly located beneath the grid, before filling the
cabinet with abrasive media. Do not fill higher than the
level of the grid.
NOTE:
PTFE tape is provided which may be used on the
threads of the various connectors to ensure an airtight
connection.
Select the ceramic abrasive nozzle to produce the
jet required for the abrasive media being used, and
assemble according to the instructions given below.
Place the object to be cleaned in the cabinet, and
close the lid, securing with the two swivel clips.
If you are using a vacuum extraction device, turn it on
before turning on the air supply. Set the pressure to
the required value, but not higher than 100 PSI, and
check to ensure there are no air leaks. Should there be
any, turn off the air supply and repair where necessary,
before turning the supply back on. Pull the trigger on
the gun and proceed to blast the object to be cleaned.
Keep the jet facing the object and away from the clear
plastic lid. Do not allow the jet to drain on the rubber
gloves, the air hose within the cabinet or the fluores-
cent lamp.
When completed, turn off the air supply first, and, as a
precautionary measure, pull the trigger before opening
the lid.

MAINTENANCE
Before use, check to ensure that all parts are service-
able, including the air inlet hose, rubber gloves and
abrasive pick-up.
Ensure the air vent foam filter is in place.
The swivel clamps, securing the lid, must be secure so
as not to allow the lid to open during operation. The
build up of air pressure within the cabinet could force
the lid open, allowing abrasive to escape. This is not
only wasteful, but could be a health hazard.
Ensure the filters are serviceable and seated correctly.
Ensure you comply with all precautions regarding the
use of compressed air, and air compressor operation.
Changing the Fluorescent Tube
Ensure the transformer is disconnected from the power
supply before opening the lid and cutting the two ties
securing the lamp to its retaining clips.
Carefully pull the lamp from its retaining clips then hold
the clear plastic protective outer tube firmly and ease
off the plastic end cover from the non-wired end. (This
may take a little persuasion and perseverance). Once
the end cover has been removed, hold the end cover
at the opposite end (the cable input end), and pull off
the outer protective clear plastic tube.
The fluorescent tube is now fully revealed. Pull off the
end connector, which secures a wire to one of the
pins, taking care not to distort the aluminium reflector.
Then pull off the wire secured by a plastic sheath to
one of the pins at the cable input end.
Assemble in reverse order, ensuring the wires are cor-
rectly held by the plastic sheath at one end and the
end connector at the other, with the reflector correctly
in position.
Replace the assembly into its retaining clips and test its
operation by plugging the transformer in to the mains.
