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.
NOTES:
There are no hard or fast rules governing nozzle sizes and air pressures used with different abrasives. With expe-
rience 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.
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.
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 100 PSI, 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 drain on the rubber
gloves, the air hose within the cabinet or the fluores-
cent lamp.
When completed, turn off the air supply first, and, as a
precautionary measure, pull the trigger before opening
the lid.
