3.1.2 Moving a blast machine
WARNING
Never manually move a blast machine when it
contains abrasive. Empty (model 1028 and
1042) machines may be moved when the
following criteria are met.
3.1.2.1 An empty machine may be moved manually on
level flat surfaces.
3.1.2.2 Move the machine by pushing it in a forward
direction. Do not back-up while moving the machine, as
potential tripping hazards cannot be seen.
3.2 Set-up
3.2.1 Locate the compressor upwind and/or away
from the blasting operation to prevent contaminated air
from entering the compressor intake.
3.2.2 Connect a 3/4" ID or larger air line from the
compressor to the air supply hose connector previously
installed on the blast machine inlet.
NOTE: If the air line supplies air to other pneumatic
tools, install isolation valves to enable depressurization
of each line for service.
WARNING
If twist-on type air hose couplings are used,
they must be secured by safety lock pins or
wires to prevent accidental disconnection while
under pressure. Hose disconnection while
under pressure could cause serious injury.
3.2.3 Make sure the coupling gaskets are in place and
in good condition before connecting the blast hose to the
quick coupling on the blast machine. To prevent
accidental separation during blasting, use safety lock-
pins or safety wire to lock the couplings together.
3.2.4 Make sure that all hose connections are secure.
Install safety lock pins on all quick couplings. Use lock
pins and safety cables at all quick coupling connections
to help prevent accidental separation of hoses. Lock
pins and safety cables are listed in Section 7.3.

WARNING
Hose disconnection while under pressure could
cause serious injury or death. Use safety lock-
pins and safety cables on all coupling
connections to help prevent hose couplings
from accidental disconnection.
3.2.5 Make sure the choke valve is open (handle in-
line with the piping).
3.2.6 Close the abrasive metering valve. The closed
position is when the handle is pointing toward the pipe
nipples in the metering valve.
3.2.7 Close the air valve on the compressor. Start the
compressor, and bring it up to operating temperature
and pressure. The pressure must not exceed 125 psi.
3.2.8 Load abrasive into the machine by following the
instructions in Section 3.6.
3.2.9 If the machine is equipped with manual valves,
make sure the inlet
perpendicular to the valve).
3.2.10 If the machine is equipped with remote controls,
make sure the control handle is in the "up" (no blast)
position.
3.2.11 Slowly open the compressor air valve to
pressurize the air supply line. Listen for noise that
indicates any open lines or leaks.
3.2.12 Do not allow anyone around the blast machine
except machine tenders, who are appropriately fitted
with approved personal protective equipment.
WARNING
Everyone except for the blast operator or blast
machine tender must stay clear of the blast
machine. The machine tender or blast operator
may pressurize or depressurize the machine at
any time, which could cause abrasive to vent
under pressure, causing dust and toxins to
become airborne. Noise is produced by the
sudden release of compressed air when the
machine is pressurized or depressurized. These
conditions could cause injury. Both the
operator and machine tender must wear
suitable personal protective equipment
including an approved respirator, plus
approved eye, face, and hearing protection.
