6. Troubleshooting

Choking.

If neither abrasive, nor air comes out of the nozzle, relieve pressure and depressurize the

machine, then ensure that the nozzle is not choked. If only air without any abrasive comes

out of the nozzle, fully open the metering valve, and then quickly close and open again

the lower ball valve of the line. If these actions do not help to relieve the pressure in the

machine, open the inspection door and ensure that there is no foreign matter in the tank

(stones, paper, etc.).

Abrasive surges.

During start-up of the machine abrasive surges are normal to a certain degree. However

id abrasive surges continue, you should stabilize the abrasive ow by quick closing and

opening of the line lower ball valve. Abrasive surges often result from elevated moisture

content in compressed air system. Installation of additional moisture and oil separator can

solve this problem.

Wet abrasive removal.

To remove wet abrasive from machine tank you should disconnect the blasting hose and

remove rubber gaskets at machine hose coupling. Then you must fully open the metering

valve and close the lower ball valve in the machine compressed air line. With such valve

conguration compressed air will only enter the machine tank and press wet abrasive out of

the tank.

6.1 RC system troubleshooting

The following list of checks can be used for determining problems in case the RC system

does not function properly:

1. Study RCV User Manual

2. Visually check all air hoses and connections to ensure that there are no air leaks.

3. Ensure that the safety and drain valve are closed.

4. Check the RC handle for air leaks:

— when the key is not depressed, the air should come only out of the body vent.

— when the key is depressed no air should come out of the handle.
