Replace the grid, ensuring the feet face

downwards with the cut away section at

the right hand rear of the cabinet. The

pick up hose should be routed throught

the gap made by the cut away portion

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 prised 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

with ensure an airtight seal.

The air supply should be dry, and capable of

delivering a minimum of 10 cuft/min at 100 lbf/in

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 100lbf/in

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, turn off the air supply first, and, as a precautionary measure,

pull the trigger before opening the lid.

NOTES:

Fig.4

T here 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.

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.

Pull the trigger of the gun as a precautionary measure.

Unscrew the End Cap and withdraw the ceramic nozzle.

, and

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. An box spanner will be required to unscrew and withdraw

the air nozzle.
