Operation

Important NoteTo prevent freezing, this equipment is shipped from thefactory with blue windshield washer fluid inside the sys-tem. Dispose of the fluid in accordance with local regula-tions.

Checklist Before Starting• Check the compressed air supply according to its

operator manual. Make sure the air being suppliedis clean and relatively free of moisture and oil to pre-vent water contamination of the air control compo-nents.

• Make sure air delivery valves are closed before theair supply compressor is started.

• Make sure all required hose restraints and couplerpins are in working condition and properly installed.

• Make sure the equipment is situated on levelground. Failure to keep the unit on level ground willmake it difficult or impossible to purge all of the airfrom the pressure vessel.

• Make sure the equipment is properly supported on asurface that can hold its total weight. The weight ofall personnel, the material being blasted, and anyabrasive being stored must also be considered.(See “Technical Data” on page 50.)

• Make sure the water tank will remain fully suppliedwith clean water to avoid any possibility of the pumprunning dry during blasting.

• Make sure that the pot is clean and free of any inter-nal debris. Make sure to use the correct type of blastcontrol. Either an electric or pneumatic blast controlswitch can be used with hose lengths less than 150ft (45 m). Blasting with 150 ft (45 m) or more of blasthose requires the use of an electric blast controlswitch.

• Make sure the blast hose is laid out as straight aspossible between the equipment and the work site.(A coiled blast hose will uncoil under pressure.)

• Make sure the rubber gasket in each hose coupleris in working condition.

Lifting the System• Lift the system with a lift apparatus rated appropri-

ately for the weight of the system. (See “TechnicalData” on page 50.)

• Do not lift the system by the lift rings on the pot.

• Lift the system using all four corner lift eyes on theframe.

NOTICE

Sharp bends in the blast hose could cause the abra-sive to wear through the hose and cause prematurefailure of the hose. Before blasting, ensure there areno tight bends or kinks in the blast hose.
