• NEVER use a wire tie to hold the applicator
trigger in the ON position. (Doing so violates safety
regulations, can damage applicator, and voids warranty coverage
of applicator.)
• ALWAYS turn source air OFF and remove
the applicator control air line before removing
the blast hose.
• ALWAYS follow the guidelines of the
governing codes of your local/national body.
• NEVER DISCONNECT the air supply hose
without first shutting off the source air and
bleeding down the system.
• ALWAYS WEAR safety glasses, gloves,
32+NRR ear plugs & ear muffs.
•NEVER OPERATE the unit without first
reading the Operator Manual.
• NEVER exceed recommended hose or
blasting unit pressure levels.
• NEVER kink the blast hose.
• ALWAYS ENSURE that hoses are securely
tightened.
• CHECK hoses and tubes for nicks and
gouges.
• ALWAYS electrostatic ground the material
being cleaned.
• NEVER OPERATE a damaged blasting
system.
• NEVER mask the ventilation holes.
General Safety Precautions

7
Electrostatic Discharge
Electrostatic discharge can be hazardous to the
operator and the equipment. The electrostatic
charge of CO2varies with the amount of
ice and humidity present. Follow these
instructions to assure safe operation while
blasting.
CAUTION:
Static discharge may
ignite flammables.
A) KNOW YOUR ENVIRONMENT
Electrostatic buildup changes as humidity levels change and will vary
by location. Electrostatic discharge is higher at low humidity levels
and occurs most often during winter.
B) ATTACH STATIC BOND CABLE
To minimize static between the part being cleaned and the
applicator, attach the static bond cable between the blast hose
connection and the part.
C) ATTACH STATIC GROUND CABLE (OPTIONAL)
If a part being cleaned is on a non-grounded surface it will build up
an electrostatic charge, which could injure the operator or damage
the equipment. Wrap or clip one end of the static ground cable to
the part to dissipate the charge and the other end to a grounded
surface. Metal framing, that holds the part in place, can be used
but the part and frame must be electrically connected. Use a
conductivity tester for confirmation.

Carbon Dioxide Safety Precautions
•This unit utilizes solid state Carbon Dioxide
(Dry Ice) as a blast media.
•Dry Ice is very cold ( -110° F / -79° C) and
may freeze skin instantly.
•CO2is heavier than air, which means it will
settle to the ground.
•Always ventilate when blasting.
•CO2is nontoxic, non-corrosive, non-
conductive and is approved by the FDA and
USDA. While exposure to CO2gas is not
harmful in low concentrations, CAUTION
should be exercised when using any material
that can DISPLACE OXYGEN.
• Please refer to Carbon Dioxide (CO2) MSDS
sheet for all safety precautions. (available from dry
ice supplier.)
ASPHYXIATION HAZARD
Increased levels of CO2when blasting in a
confined space can displace breathable oxygen
creating a risk of serious injury or death,
therefore use of a carbon dioxide monitoring
device is required when using in a confined
space.
BURN HAZARD
Do not allow skin to directly contact dry
ice. Always use protective clothing (Thermal
Gloves) and eye protection when handling CO2
solids or when using the blasting unit.
Carbon Dioxide
(CO2) is a naturally
occurring non-toxic
gas, however cau-
tion should be
exercised.

9
A) ERGONOMICS
CO2blasting involves direct discharge
of an air powered blasting nozzle. The
operator experiences a reactive thrust which
increases with blast pressure and air flow.
Operator fatigue may become a concern
depending on issues such as blasting
angle, work area, temperature, operator
strength and level of physical conditioning.
Do not exceed allowable limits of blast
pressure, duty cycle and total blast time as
determined by on site health and safety
personnel knowledgeable about site-
specific conditions and available worker
population.
B) PNEUMATIC STORED ENERGY HAZARD
The control circuitry of this machine may
trap air in and between devices. Vent
machine before servicing to prevent
accidental release of trapped air.
C) LOCK OUT/TAG OUT WARNING
Do not attempt any maintenance procedure
unless all input air sources are locked out
and tagged out according to applicable
regulations.

Operation

18
Start Up
Make sure the Blast Indicator is RED and the bleed valve
is closed.
Attach the blast hose and control tubing to the machine.
Attach the applicator to the blast hose and control
tubing.
Attach a nozzle to the applicator.
Attach the air supply hose on the machine.
(Check the data plate for the operating pressure range.)
Connect one end of the static ground cable to the item
being blasted and the other end to the connector on
the blast hose or to an electrically conductive supporting
structure.
Turn air supply on and allow the air hose to pressurize.
Press the green Enable Blast Button - the indicator
should turn green when the machine is operational.

10 Push the applicator safety switch forward. Run with
no ice for 1 min. Fill hopper with ice... (Note: If water
content of compressed air is relatively high, adjust
bleed valve so a very small amount of air/water may
continuously drain.
Pull out the yellow Disable Blast button

19
Shut Down
Stop blasting and enable the safety by pushing the switch
back to the (O) position on blast applicator.
1Run machine until all remaining ice in the hopper has been
used.*
2
Turn OFF the compressed air supply.
3Press the Control Panel Disable Blast button to shut down the
machine.
4
Open the bleed valve to relieve all remaining pressure.
5
If open, close the fill lid.
6
When the air hose is fully depressurized disconnect the
machine.
7
When shutting the machine down for more than 15
minutes, always make sure the hopper is empty and blast
with air only for 1 min. Failure to do so may result in feeder
and/or nozzle freeze-up.
