CAUTION
Read the instructions before using the machine. Only qualified personnel should
operate the machine.
WARNING
Ensure adequate ventilation when operating this equipment to prevent the build-up of
carbon dioxide gas. If used indoors or other confined space, a CO2detector should be
used to monitor for excessive unsafe levels of CO2gas and provide a suitable warning.
The legal exposure limit by OSHA is a 0.5% average over an 8-hour workday and the
acute (15 minute) exposure limit is 3.0%.
WARNING
Ensure that expended dry ice pellet emissions are not in the vicinity of air ducts that
could allow CO2to enter another space.
WARNING
Due to the nature of dry ice and atmospheric conditions, use caution when operating,
storing, and cleaning the machine as condensate can build up and leave moisture on
the ground near the machine and blast hose. It is recommended to wear appropriate
non-slip work shoes and it is necessary to wipe up and dry any condensate from the
work area that could cause a slip hazard.
WARNING
This machine has been designed for use with 3mm dry ice pellets recommended by
Cold Jet. The use of other cleaning agents or chemicals may adversely affect the safety
of the machine.
WARNING
High pressure blast streams can be dangerous if subject to misuse. The blast stream
must never be directed at persons, live electrical equipment, or the machine itself.

Steps for conducting a Lockout Tagout or “LO/TO”
•Throughout this manual, “Lockout Tagout” (LO/TO) will be referred to in instances when power
must be removed from the machine.
•There are (6) universally accepted basics to this procedure. They are listed below but may not be
limited to these (6) steps; each individual entity owning and/or operating a machine may have
their own LO/TO procedures. Please refer to those procedures and decide which procedure will
provide the safest working conditions and environment.
Procedure
NOTE: There are two energy sources that supply the machine –an electrical supply and a
compressed air supply. Both energy sources must be removed.
1. Shut Down: Use the machine’s power button to turn off power.
2. Isolation:
a. Unplug the power cord from the supply source.
b. Leave power cord within visual distance of the machine.
c. Turn off and disconnect the compressed air supplying the machine.
3. Check for Stored Energy: At the applicator, press the “Air-Only” once, pull the trigger. No activity
should be present at the machine.
4. Isolation Verification: Does the machine have electric power or compressed air present? The
power button should not be lit; it should be off. The HMI display should have no images present.
At the applicator, press the “Air-Only” once, pull the trigger. No activity should be present at the
machine.
5. Verify the reason for using the LO/TO procedure has been solved. For example, if the
reason for initiating the LO/TO procedure was a screwdriver that fell into the hopper causing the
doser to stop, verify that the screwdriver has been removed. Once verified that the problem is
solved, follow the instructions in the “Starting the Machine”section of this manual.

•The Emergency Stop button is used if the machine must be shut down immediately.
•If any event occurs that could cause harm to personnel or equipment, then use the Emergency
Stop to shut down the machine.
•The Emergency Stop button is a push button. Once pushed, the button becomes locked in the
down position. The button must be rotated clockwise to reset. Once rotated, the button will pop
outward to its ready state. The display on the machine will show the “Reset Screen.” See Reset
Screen section for instructions on how to use the machine again.
•NOTE: When the machine is in idle, such as between cleaning cycles, the machine has full power
to all functions and motors.
•NOTE: When the Emergency Stop has been activated, there is only power going to the control
board and safety relay. Nothing on the machine will operate until the emergency stop has been
reset.
Reset Screen
•The reset screen appears if the Emergency Stop Button has been depressed (activated) or if the
safety grate has been opened.
•If an emergency has occurred in which the Emergency Stop button has been depressed (activated)
a. Correct any issues that initially caused the emergency.
b. When the issue(s) have been corrected, reset the Emergency Stop button by following
the instructions in the Emergency Stop section of this manual.
c. Press the rotary encoder dial on the reset screen as shown above. This will cause the
machine to go through a calibration sequence that lasts about (15) seconds. It will then
return to its last mode of operation prior to shut down.
•If the Safety Grate has been opened, close it. Then, press the rotary encoder dial on the reset
screen as shown above. This will cause the machine to go through a calibration sequence that lasts
about (15) seconds. It will then return to its last mode of operation prior to shut down.
