General Safety Precautions
• 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 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.
• DO NOT ever kink the blast hose.
• ALWAYS ENSURE that hoses are securely
tightened.
• ALWAYS electrostatic ground the material
being cleaned.
• CHECK hoses and tubes for nicks and gouges.
• NEVER OPERATE a damaged blasting system.
• NEVER mask the ventilation holes.

Electrostatic Discharge
Electrostatic discharge can be hazardous to the
operator and the equipment. The static charge
of CO2 varies with the amount of ice and
humidity present. Follow these instructions to
assure safe operation while blasting.
CAUTION:
Static discharge may
ignite flammables.
A) PLUG INTO A GROUNDED POWER OUTLET
This is critical for electrostatic dissipation. If the ground is not
connected a charge may build up on the unit or the applicator.
B) 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.
C) 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.

Carbon Dioxide Safety Precautions
Carbon Dioxide
(CO2) is a naturally
occurring non-toxic
gas, however cau-
tion should be
exercised.
• 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.
• CO2 is heavier than air, which means it will
settle to the ground.
• Always ventilate when blasting.
• CO2 is nontoxic, non-corrosive, non-
conductive and is approved by the FDA and
USDA. While exposure to CO2 gas 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 CO2 when 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.

Machine Safety
A) ERGONOMICS
CO2 blasting 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) LOCK OUT/TAG OUT WARNING
Do not attempt any maintenance procedure
unless all input air and electrical sources are
locked out and tagged out according to
applicable regulations.
C) FINGER GUARD PRECAUTIONS
The finger guard on the feeder protects
from a potential personal injury site located
inside the machine. The guard, over the
exhaust port, must remain installed at all
times to serve it’s function.

Start Up
Make sure the Power Switch is off and the bleed valve is
closed.
Attach the blast hose and control cable to the machine.
Attach the applicator to the blast hose and control cable.
Attach a nozzle to the applicator.
Attach the whip check to the air supply hose, then attach
the air supply hose to the machine.
(Check the data plate for the operating pressure range.)
Connect the staticbond cable to the connector on the
hose and then to the target surface.
Turn air supply on and allow the air hose to pressurize.

10 Enable the applicator by pushing the Trigger Switch to
the ON (I) position. Turn the bleed valve ON (I) to purge
water out of the system, then turn it OFF (O) to close
it. The unit is now ready to blast. (Note: If water content of
compressed air is relatively high, adjust bleed valve so a very small
amount of air/water may continuously drain.)
Turn the Control Panel Power Switch on.
Plug the power cord into an electrical outlet. If an
extension cord is necessary, it must comply with the power
requirements of this unit and all governing electrical codes.
(Check the data plate for the operating voltage range.)

Shut Down
Stop blasting and disable the Applicator Safety by pushing
the switch, located on the applicator handle, back to the (O)
position.

2
Turn OFF the compressed air supply.
3
Turn OFF the Power Switch.
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.
When shutting the machine down for more than 15
minutes, always make sure the hopper is empty and blast
with air only for 1 minute. Failure to do so may result in
feeder and/or nozzle freeze-up.
*
Stop blasting and push in the Disable Blast Button on the
Control Panel.
Remove unused ice from the hopper.
Pull out the Disable Blast Button on the Control Panel.
Flip the Air/Ice Control Switch on the Applicator to Air Only
(I) and blast for 1 minute.
