1.3 DRY ICE SAFETY PRECAUTIONS
Dry Ice (Solid CO2) Safety Data
• At a temperature of -110°F (-79°C), insulated gloves should be worn at all times
when handling dry ice to prevent frostbite.
• Proper eye, ear and skin protection should be worn at all times when operating or
in the vicinity of dry ice blasting equipment.
• Even though CO2gas is non-poisonous, it does displace oxygen in the atmosphere
so working spaces should be properly ventilated. Because CO2is 40% heavier
than air, when blasting in an enclosed area, placement of exhaust vents at or
near ground level is recommended. In an open environment, existing ventilation is
sufcient to prevent undue CO2buildup. It is recommended that a breathing appa-
ratus is used in enclosed work areas where CO2gas may accumulate to hazard-
ous levels.
• Store dry ice only in containers approved and labeled for dry ice storage. Storing
dry ice in a container without proper ventilation may result in an explosion hazard
due to the pressure that builds up when dry ice sublimates into gas form.
• Ensure your dry ice supplier provides a current MSDS sheet for any additional
safety information
First Aid Measures
Contact with Skin: Immediately ush effected area with warm water. Do not attempt to pop
any blisters that may appear as a result of frostbite. Seek medical assistance as soon as
possible.
Contact with Eyes: Immediately ush eyes thoroughly with water for at least 15 minutes. In
case of frostbite, spray with lukewarm water for at least 15 minutes. Apply a sterile dressing.
Seek medical assistance as soon as possible.
Excess Inhalation: In high concentrations (5000 ppm or higher), CO2can cause asphyxia-
tion by displacing the oxygen required for breathing. Symptoms may include loss of mobility
or consciousness. The victim may not be aware of asphyxiation. In case of asphyxiation,
immediately move victim to an uncontaminated area. Apply articial respiration if breathing
has stopped. Keep victim warm and rested. Seek medical assistance as soon as possible.
Refer to the MSDS sheet provided by your dry ice supplier for additional rst aid
information.
Safety Training
Asphyxiation and other potential safety hazards must be stressed during operator training.
Always review safety procedures with operators before allowing them to operate any dry ice
blasting equipment. Before using this product in any new process, a material compatibility
and safety study should be performed.
Always ensure that all Local, State and Federal Laws and Regulations are observed, includ-
ing Regulations of Foreign Governments.

Nu-Ice Age, Inc. • Jackson, MI USA • Customer Service: 517-990-0665 • www.nuiceage.com
Prior to blasting, carry out a risk assessment in order to have the proper safety precautions
in place. Ensure that those operating the equipment have been properly trained and under-
stand the risks associated with dry ice. Always secure the area that is to be blasted with
dry ice — no unauthorized or untrained personnel should be allowed to operate the
machine or enter the working area.
Conrm the nature of the coating or substance that is to be cleaned before beginning
the blasting process. If hazardous materials are present, appropriate safety precautions
must be taken to avoid exposure, such as local exhaust ventilation or personal protective
equipment.
Always inspect air supply and blasting hoses for any potential damage and ensure all
connections are secure prior to operation.
This machine may be used indoors and outdoors. Operating the machine in heavy
rain is not recommended, water will freeze up the dry ice pellets and clog the hopper.
Follow All Safety Precautions During Setup and Operation shown on Page 7
When transporting the machine, always secure with straps or other appropriate method to
avoid the risk of damaging equipment.
Do not transport dry ice in any vehicle where the storage area is not separate from the driv-
er’s compartment (such as a car or station wagon). Driver must be aware of the potential
hazards of CO2and know what to do in the event of an accident or emergency. Ensure dry
ice containers are secured and that adequate ventilation is provided before transporting.
Unused dry ice may still remain in the ice blaster after blast cleaning work. As a safety
precaution, purge the remaining dry ice from the machine until the hopper is empty. This also
prevents ice clumps from building up in the machine.
Only properly labeled equipment that is approved for use with dry ice should be used
to store dry ice pellets. Always keep containers in a well-ventilated area.

FACE PROTECTION OR GOGGLES
Always wear safety goggles or face protection when operating dry ice blast-
ing equipment, especially to ensure protection from any blowback of the
contaminant being removed.
EAR PROTECTION
Always wear proper hearing protection. Harmful noise levels can be experi-
enced that can result in permanent hearing loss. Nearby workers must also
have hearing protection when standing within 100 ft (30.5 m) of the work
area. Double ear protection (ear plugs & ear muffs) is recommended to all
workers in the blasting area. Pregnant women should not operate machine
or be in the noise area.
PROTECTIVE GLOVES
Always use suitably insulated protective gloves when handling dry ice or
cold parts of the machinery. Contact with dry ice may cause cold burns or
frostbite, use gloves and the supplied Ice Scoop to avoid this.
BREATHING APPARATUS
Wherever suitable ventilation cannot be provided, a breathing apparatus
with a supply of breathing air should be present. Dry ice blasting can cause
airborn particulates and correct respiratory protection should be matched
with the contaminant(s) being removed (i.e. mold, lead paint, etc.).
ASPHYXIATION HAZARD
In small enclosed rooms and areas with little or no ventilation, CO2
may accumulate to dangerous levels. A CO2detector should be used
to conrm safe conditions. Where necessary, a breathing mask with a
fresh air supply should be worn.
CAUTION!
Never touch the pellet stream or nozzle during operation.
Never blast or aim blasting gun at people or animals.
Do not ingest dry ice or handle without proper protection.
LOW TEMPERATURE
The temperature of dry ice is -110°F (-79°C). Do not touch or allow direct
contact with dry ice. Always use protective clothing and gloves when
handling dry ice and equipment that contains dry ice.
ELECTRIC SHOCK HAZARD
Objects to be cleaned must be grounded in order to avoid a potential
static electrical discharge caused by the velocity of the pellets in the air
stream. Do not operate the blaster if you wear a pacemaker.

Use the connection piece to connect the nozzle to the
gun or extension pipe (if tted). Attach the twist-grip
handle by hand tightening onto the extension.
A selection of nozzles are available for a variety of differ-
ent cleaning applications. It is recommended that a test
area be blasted rst to establish which nozzle will func-
tion the best for each cleaning application. Always turn
off the power when changing blasting nozzles.
4. Compressor Connection:
An air hose with a female JIC #16 tting will be required
for operation. Ensure the yellow lever on the air bleed-
off valve is in the closed position (90° to valve). Attach
the safety lanyard to the hose by pulling the spring
back until the loop ts over the air hose. Connect the
compressed air hose from the air source (such as a
portable compressor or xed compressed air system)
to the compressed air inlet on the back of the blast-
er as shown. Use a 1 3/8” wrench to secure the JIC
tting. Ensure that all hoses are connected properly
and inspect for any damage. Replace damaged hoses
as needed.
Always use clean, dry air free from oil, particles and
humidity. An aftercooler/air dryer is often recommended
(portable units available from Nu-Ice Age). When using
shop air, ensure that consideration has been given to
the volume of air required for operation.
Never disconnect hoses while the machine is in opera-
tion. At the end of a cleaning job, rst shut down the
compressed air source, then press the yellow lever
on the bleed off valve in the open position (parallel to
valve) to depressurize.
5. Static Ground Wire:
To minimize the risk of shock due to static electricity,
always attach the static ground wire to the object you
are blasting. Ensure that the location of the clip is not
in an area where it is at risk of being blasted off or slip-
ping off.

3.0 DRY ICE PELLET SIZE & QUALITY
Dry ice pellets contaminated with moisture can
result in freezing of the air chamber rotor and hose.
Pellets typically become mushy or clumped together
when they contain too much moisture. For best
performance, the use of fresh dry ice pellets without
signs of moisture contamination is recommended.
To the left is an example of dry ice pellets that are
compatible with the Commando 55 Dry Ice Blaster.
The correct size of dry ice pellets for the Commando 55 is approx. 1/8” (3 mm) dia. and is
commonly referred to as “blasting rice.”
Any foreign objects other than dry ice pellets that fall into the hopper can result in serious
damage to the air/CO2chamber.
Always keep the top lid closed during operation to avoid dirt and debris from falling into the
hopper.
Do not leave dry ice in the hopper for an extended period of time (10 minutes or more). It
may solidify and cause a blockage.

Safety
Trigger (also activates light)
Ice ON/OFF Switch
Open the valve slowly at the air supply to the blaster in order to avoid pressure shock to the
hose and the machine. This will prevent damage to pneumatic components.
Adjust the working pressure to what is required for each job. It is highly recommended that
a test clean is performed at low pressure and gradually increased until the point where it
removes the unwanted substrate or coating.
Prior to lling dry ice into the hopper ALWAYS activate the blast function for about 30
seconds by pulling the trigger on the gun to empty the hose and machine of humidity
and moisture.
Pour dry ice into the hopper. Fresh dry ice is always recommended to avoid clogging. Close
the lid to minimize evaporation of dry ice and the ingress of humidity and dirt. Do not overll
to the point where the lid cannot be closed. Use only dry ice — use of other materials in this
machine will void the warranty. Upon initial use, start by pouring about a gallon of dry ice in
the hopper and blast it out. This will allow the parts to chill and then you can ll the hopper
with ice as needed.
Do not blast without any dry ice in the hopper (after initial system purging). Without dry ice
the feed wheel inside the machine will run extremely hot and may be damaged.
Start of Dry Ice Blasting
When the blaster is connected properly, correct air pressure is adjusted and dry ice is in the
hopper, you are ready to begin dry ice blasting.
Before beginning, have a rm grip of the gun and do not point at yourself or in the direction of
other people. Stand in a safe working position.
To start ice blasting, rst ensure the power switch is in the ON position. To engage, push down
the safety lever on the gun, then pull the trigger on the pistol grip (once started it is only neces-
sary to keep the trigger pressed). If only air is spraying from the gun, press the ice on/off switch
to turn on the ice.
When starting, keep the gun
some distance from the object
to be cleaned until you are able
to conrm the back-pressure of
the gun. Blasting pressure and
amount of dry ice can be adjust-
ed during operation.

Operation Manual
13 Rev. 1/14
Nu-Ice Age, Inc. • Jackson, MI USA • Customer Service: 517-990-0665 • www.nuiceage.com
Stop of Dry Ice Blasting
To stop blasting, release the trigger on the gun. Once the trigger is released, the vibrator
will stop, however air will continue to ow for approx. 1/2 second to purge any dry ice left
in the hose.
If stopping for more than 30 minutes, ensure the hopper is empty and blast air through the
system for a short period to clear out any dry ice that may be left in the system. This avoids
dry ice clumping in the hopper and air chamber chute.
Important! When the system is empty, stop blasting to avoid unnecessary wear on
the feed wheel.
If dry ice pellets are not returned to storage immediately, care should be taken to ensure
their safe disposal. Avoid leaving pellets exposed where untrained personnel or children
may be able to touch them, or in an enclosed area where sublimation could cause a hazard-
ous atmosphere.
WARNING
Do not attempt to modify any controls or other components on this machine.
Tampering with the safety trigger, pressure control, pressure relief valve or
any other components can lead to serious risk of injury.
4.3 START/STOP PROCEDURES (continued)
• Small objects should be xed or mounted properly before blasting.
• Do not leave loose parts in the blasting area.
• Some dry contaminants tend to pulverize while cleaning. If a maximum total dust
concentration of 6 mg/m3 (ne dust) is exceeded, a breathing mask must be worn.
Protective measures should be taken such as Local exhaust ventilation and/or
other personal protective equipment. A suitable mask or other control measures
may be required to protect against specic hazardous contaminants. In poorly
ventilated enclosed spaces, forced ventilation or breathing apparatus may be
required to avoid asphyxiation by sublimated carbon dioxide.
• The nozzle gun discharges gases and CO2pellets at very high velocities (up to
300 m/sec or 1000 ft/sec). Never aim the gun at human beings or animals as seri-
ous/fatal injuries may be caused.
• When activating blasting, back-thrust will occur in the opposite direction of the
airow. In order to anticipate the reactive thrust, always take a wide stance (with
feet approx. 2 ft or 60 cm apart) and your upper body leaning into the direction
where the nozzle is pointing.

6.0 CLEANING INSTRUCTIONS
Automatic Moisture Filter
On the back of the machine is an automatic lter/drain for removal
of moisture in the air line. This lter will automatically drain when full.
Frequency of drainage will vary based on the amount of moisture in the
air supply line, and if a dryer is installed in the air supply system the lter
will likely drain less frequently.
Clean your dry ice blasting machine with low pressure compressed air.
If the equipment has become dirty, it should be cleaned by means of a
wiper moistened with a cleaning material (degreaser). Do not pressure
wash.
