DESCRIPTION
The cabinet is lit by a low voltage (12 volt) fluorescent tube, fed from a plug-in
type transformer. The switchbox is mounted on the left side of the cabinet. The
transformer should be plugged directly into the mains supply and connected
to the switchbox which contains the ON/OFF rocker switch.
A vacuum extraction device must be used, connected to the port in the left
side of the cabinet.
At the rear of the cabinet is a breather, which must be clear at all times.
The cabinet is provided with a window, the inside of which is protected by a
clear plastic membrane. The protective membrane may be renewed quickly
and easily should it become damaged by the sand blast 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 cuft/min at a maximum 100psi. 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.
If an air compressor is used, ensure it is located well away from the cabinet.
SAFETY PRECAUTIONS
Ensure you comply with all precautions regarding the use of air compressors
and compressed air.
• Ensure all air connections are secure.
• Do not use the machine if the integral gloves are ripped or unserviceable.
• Keep the jet well away from the air hose, gloves, florescent tube & window.
• Ensure the clear plastic lid is firmly secured before pressing the trigger.
ALWAYS wear safety glasses. (Normal eye glasses are NOT safety glasses).
• Do not use any silica based abrasives with this tool. Silica based abrasives
have been linked to severe respiratory disease. Always use recommended
abrasives. Abrasives used in this unit may be covered by COSHH
Regulations.

ASSEMBLY
NOTE: PTFE tape is provided for use to ensure an airtight fit.
1. Lay the cabinet on its back and
attach the four legs using the M6
x12mm screws, flat washers and
nuts, ensuring the flat washers are
against the screw heads.
2. Fit the intake vent cover to the
cabinet.
3. Attach the pick-up tube to the
funnel as shown, using the M6 x
12mm screws provided.
4. If not already fitted, peel the
backing paper from the foam strip
and apply the strip to the edge of
the grid support. Trim the strip
accordingly.
5. Use a punch (or similar) to make
holes in the foam strip, at the bolt
holes.
6. Place the grid support on the
funnel flange and the grid into the
recess in the grid support, so that the pick-up tube protrudes through the
grid neatly. Do not use undue force.
7. Turn the cabinet on to its legs then
and with assistance, raise the
funnel to meet the underside of
the cabinet, ensuring the pickup
tube is at the front of the cabinet.
Bolt the funnel assembly to the
cabinet using the M6 x 20mm
screws with the nuts and flat
washers provided, ensuring the
flat washers are against the screw
heads.
8. Open the cabinet door and attach the air hose from the gun to the inlet
port on the front of the cabinet, then connect the pick-up hose from the
gun to the pick-up tube attached to the funnel, securing with the worm
drive clip provided.
9. Attach the shelf to the legs using the screws and nuts provided.

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 swivel clip.
Turn on the extraction device which must be attached to the port on the left
side of the cabinet before turning on the air supply.
Set the pressure to the required value, but not higher than 100lbf/in2, 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 train on the rubber gloves, the air hose within the cabinet or
the fluorescent lamp.
When completed, release the trigger then turn off the air supply. As a
precautionary measure, ALWAYS pull the trigger before opening the lid.
NOTE: There are no hard or fast rules governing nozzle sizes and air
pressures used with different abrasives. With experience and
experimentation you will quickly learn the best combinations for
the required result.
NOTE: On more delicate parts, start with minimal air pressure to avoid
unnecessary peaning or excessive abrasion, and work up to a
setting to produce the desired finish.

CAUTION: 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.
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.
MAINTENANCE
Before use, check to ensure that all parts are serviceable, including the air
inlet hose, rubber gloves. and abrasive pick up.
The door securing clamp must be perfectly serviceable so as not to allow the
door to open during operation. The build up of air pressure within the cabinet
could force the door open, allowing abrasive to escape. This is not only
wasteful, but could be a health hazard.
Change the window protective film should visibility be impaired. Simply peal
off the old film and replace with a new one. Replacement protection film is
available from your Clarke dealer.

Ensure you comply with all precautions regarding the use of compressed air,
and air compressor operation.
Inspect the abrasive media regularly. If badly contaminated, it should be
replaced. A hinged cover is provided at the base of the funnel to allow quick
draining of the media.
CHANGING THE FLUORESCENT TUBE
Ensure the transformer is disconnected from the power supply before opening
the door and cutting the two ties securing the lamp to its retaining clips.
Carefully pull the lamp from the 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 correctly held by the plastic
sheath at one end and the end connector at the other, with the reflector
correctly in position.
Re-fit the assembly into its retaining clips and test its operation by plugging the
transformer into the mains.
