3.0 SETUP
3.1 General
Setup
3.1.1
An air filter is recommended in the air supply to
remove condensed moisture from the air line.
3.1.2
Connect the Power Gun’s air hose to a 3/4” or
larger air supply line. An isolation valve is required at the
air source to enable depressurization.
3.1.3
Secure all compressed-air supply hose
connections with safety lock pins and safety cables to
prevent accidental disconnection. Lock pins and safety
cables are listed in Section 9.1.
WARNING
Hose disconnection while under pressure can
cause serious injury or death. Use safety lock
pins or safety wire to lock twist-on claw type
couplings together and prevent accidental
separation, and safety cables to prevent hose
from whipping should separation occur
.
3.1.4
Make sure the setscrews securing the nozzle,
jet, and gun assembly are tight.
3.2
Water Connection (H2O Model), Figure 5
3.2.1
Connect the water hose to a water faucet.
3.2.2
Make sure the water valve is in the OFF
position, handle perpendicular to the valve.
Figure

3.2.3
Loosen the air-induction tensioning knob and
rotate the sleeve to close the induction port. Tighten the
knob to secure.
3.2.4
Connect the water hose to a faucet; use a
garden hose if additional hose is needed.
3.2.5
Open the faucet to supply water to the Power
Gun.
3.2.6
Begin dry blasting per Section 4.5. After dry
blasting adjustments are made, open the water valve as
needed to regulate water flow. Open the valve only
enough to water to suppress dust and prevent it from
being airborne.
4.0 OPERATION
NOTE: Unless noted otherwise, the sequence of
operation in Sections 4.1 through 4.4 may be done in
any order that is best suited for the application.
4.1
Start Compressed Air Supply
4.1.1
For onsite blasting, locate the compressor
upwind and away from the blasting operation.
4.1.2
Make sure that all compressed-air supply-hose
claw-type couplings are secure with safety lock pins and
safety cables to prevent accidental disconnection. Lock
pins and safety cables are listed in Section 9.1.
WARNING
Hose disconnection while under pressure can
cause serious injury or death. Use safety lock
pins and safety cables on all blast hose and air
hose coupling connections to help prevent
hose couplings from accidental disconnection.
4.1.3
Close the air-supply valve, start the compressor
and bring it up to operating temperature and pressure.
4.1.4
Slowly open the compressor air valve to
pressurize the air-supply line. Listen for noise that
indicates any open lines or leaks.
4.1.5
Do not allow anyone around the blasting area
who is not appropriately fitted with approved personal
protective equipment, per Section 4.2.
