Checklist Checklist Before
• 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
334143C

44).
• 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).
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.
