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.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

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.
