Checklist Before Starting
•Check the compressed air supply according to its operator manual. Make sure the air being supplied is clean and relatively free of moisture and oil
to prevent water contamination of the air control components.
•Make sure air delivery valves are closed before the air supply compressor is started.
•Make sure all required hose restraints and coupler pins are in working condition and properly installed.
•Make sure the equipment is situated on level ground. Failure to keep the unit on level ground will make it difficult or impossible to purge all of the air from the pressure vessel.
•Make sure the equipment is properly supported on a surface that can hold its total weight. The weight of all personnel, the material being blasted, and any abrasive being stored must also be considered (see Technical Specifications, page 45).
•Make sure the water tank will remain fully supplied with clean water to avoid any possibility of the pump running dry during blasting.
•Make sure that the pot is clean and free of any internal debris.
•Make sure to use the correct type of blast control. Blasting with 150 feet (45 m) or more of blast hose requires the use of an electric blast control. An electric blast control can also be used on hose lengths below 150 feet (45 m).
•Make sure the blast hose is laid out as straight as possible between the equipment and the work site (a coiled blast hose will uncoil under pressure).
NOTICE
Sharp bends in the blast hose could cause the abrasive to wear through the hose and cause premature failure of the hose.
•Make sure the rubber gasket in each hose coupler is in working condition.
