DESCRIPTION

The cabinet is lit by a low voltage (12 volt) fluorescent tube, fed from a plug-in type transformer. The switch box is mounted on the left side of the cabinet. The transformer should be plugged directly into the mains supply and connected to the switch box 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 sandblast 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 aluminum).
It is necessary to provide a clean, dry air supply, capable of delivering a minimum of 10 ft/min at a maximum of 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 eyeglasses 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.  grid neatly. Do not use undue force.

7. Turn the cabinet onto 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 it according to the instructions given below.
Place the object to be cleaned in the cabinet, and close the lid, securing it 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 planning 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 onto 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, and 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 peel off the old film and replace it with a new one. The 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 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 aluminum 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.
