Operation
Important Note
To prevent freezing, this equipment is shipped from the
factory 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 supplied
is 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 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 Data” on page 50.)
•
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 inter-
nal debris. Make sure to use the correct type of blast
control. Either an electric or pneumatic blast control
switch can be used with hose lengths less than 150
ft (45 m). Blasting with 150 ft (45 m) or more of blast
hose requires the use of an electric blast control
switch.
•
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.)
•
Make sure the rubber gasket in each hose coupler
is in working condition.
Lifting the System
•
Lift the system with a lift apparatus rated appropri-
ately for the weight of the system. (See “Technical
Data” 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 the
frame.
NOTICE
Sharp bends in the blast hose could cause the abra-
sive to wear through the hose and cause premature
failure of the hose. Before blasting, ensure there are
no tight bends or kinks in the blast hose.
