nozzles. To fit a new nozzle, unscrew the nozzle retaining ring, remove the existing nozzle and replace with the new one. Place the
workpiece in the centre of the cabinet and ensure you close and latch side door.
WARNING! Failure to securely close the door could result in damage and/or personal injury.
4.2
Connect the transformer plug to the mains power supply and switch the internal cabinet light on.
Turn the air supply on, (having first adjusted to 90psi). If attached, start the dust extraction unit. If no extraction unit is available,
remove the air flow cover from rear (Fig.1-8).
4.3
Insert your hands into the rubber gloves inside the cabinet making sure that your fingers are correctly positioned and check that you
are able to easily move your hands and grasp objects correctly.
4.4
Grasp the gun with one hand and point the nozzle at the bottom of the cabinet. Depress the trigger to start the blasting process and
check to ensure everything is working correctly. If there are any leaks, stop and fix before use. If no flow is achieved, momentarily
cover the gun nozzle in order to force the compressed air back through the grit hose to clear any lodged media.
4.5
Hold the workpiece with the other glove. Hold and move the workpiece to ensure you keep glove and fingers out of the nozzle blast
stream. DO NOT aim the blast at your fingers, gloves or internal light.
4.6
Aim the nozzle directly at the surface of the workpiece and move the blast media (which looks like steam) continuously over the
workpiece in an even and circular motion. To avoid undesirable peening, the flow should not be too hard or concentrated. The work
finish may vary from coarse to fine depending on the size of the abrasive media. On delicate workpieces, to avoid unnecessary
peening or excessive abrasion, begin the blasting with a reduced airflow.
4.7
To open the cabinet to check progress or to access content, release the trigger and lay the gun on the mesh shelf. Remove your gun
hand first, and then your other hand. Only then is it safe to open the side door.
4.8
When work is complete, disconnect gun from the air line, unplug from the mains electrical supply and switch off dust extraction.
5. MAINTENANCE
WARNING! Ensure the cabinet is disconnected from the electrical and air supplies before attempting any maintenance.
5.1
Keep the blast cabinet clean and dry. Do not use abrasives to clean the unit.
5.2
Ensure the blasting media does not become damp. Keep the air supply dry at all times. Dispose of any damp media.
5.3
Replace media when it has becomes excessively dusty, loses its granular or spherical appearance, or debris from workpieces mixes in
with it. This is usually noticed when media from the nozzle looks like a smoke cloud rather than steam.
5.4
To change media, place an appropriate container under funnel outlet and turn the locking lever to open. Wear a dust mask to perform this task.
5.5
If used, regularly check that the exhaust vent at the back of the cabinet (fig.1-8) is clear and not blocked.
If you use an extraction unit change the filters according to use.
5.6
Regularly check gun blast nozzle to ensure it does not become blocked with media. Immediately replace worn or damaged nozzles.
5.7
If abrasive pick-up hose becomes blocked, re-power the unit and ensure the door is correctly closed. Cover the gun tip and force air
back through the hose to clear any media.
5.8
The transparent screen has a replaceable covering on the underside of the lid. If visibility is reduced, replace the protective cover.
5.9
Check that the gloves are in good condition. If damaged replace immediately.
5.10
To replace internal cabinet light.
Undo the nut and bolt on each end clamp. Push the light towards the cabinet side until it is out of the nearest clamp. Angle the light
downwards and pull it towards you to release it from the far clamp. Remove each plastic end (these are a tight fit) and slide the light
assembly out of the clear tube. Disconnect the electrical terminals and gently slip the rubber retaining rings from the tube releasing it
from the back reflector. Slip the rubber retaining rings onto the new tube and connect the terminals at either end. Bring the reflector up
behind the tube and slide the assembly back into the clear tube. Refit the end caps and slide the assembly into the clear tube.
Replace end caps and remount in the cabinet.
