5. Maintenance
5.1. Preventive maintenance.
5.1.1 GX manual blast gun
Inspect the GX manual blast gun for wear. Replacing the air jet cover before it wears
through will prolong the life of the jet.
5.1.2 Dust container
Empty the dust container regularly. Start by checking the container at least daily or when
adding media, then adjust frequency based on usage, contamination and friability of the media.
5.1.3 Reclaimer debris screen
The screen is accessible through the reclaimer door. With the exhauster off, remove the
screen and empty it daily or when loading media. Empty the screen more often if parts being
blasted causes excessive debris. Do not operate the machine without the screen in place.
5.1.4 Airline filter
The cabinet is equipped with a manual drain airline filter. Drain the airline filter at least
once a day, more often if required, or if water mist is seen coming out the nozzle.
Moist air inhibits the flow of media. If moisture continues to be present, a refrigerated
air dryer may be required.
5.1.5 Media Hose
To avoid unscheduled down-time, inspect the media hose for thin spots, especially
along an outside radius.
5.1.6 Changing the rubber shield of the reclaimer
A rubber shield (3) is installed to prevent damage to the walls of the reclaimer (1),
caused by abrasive particles when the abrasive-air mixture enters the reclaimer. It should
be regularly inspected for wear and damage. Loosening the clamp (9), unscrew the hose
