The owner of this machine is responsible for verifying the operator of this machine is properly
trained and understands the contents of this manual.
About The PLT 60
This machine combines patented technology in a lightweight and compact design that gives the
operator unparalleled control for dry ice cleaning and other applications.
yThe Advanced Air-Flow System reduces pressure loss as the air ows straight through the
system which also decreases sublimation and loss of the dry ice particles.
yThe Blast Pressure Control System can be regulated digitally from the 7” HMI color screen on
the control panel or certain applicators.
yThe SureFlow System with Dynamic Agitation is designed to keep warm air, moisture and
debris out of the hopper while keeping the dry ice owing. The level of dry ice in the hopper
can be monitored from the HMI screen of the control panel or certain applicators.
yThe Advanced Direct Drive Feeding System is a two-stage feeding system that improves feed
rate consistency and maximizes dry ice particle integrity.
Environmental Impact
Dry ice is a safe, clean and non-toxic medium approved by the EPA, USDA and FDA. The dry ice used
in this machine is made from reclaimed CO2 generated from other industrial processes.

Safety
General Safety Guidelines
This machine is designed to comply with international design standards and the European
Machinery Directives. Therefore, using the machine does not pose a risk to the operator when the
instructions in this manual are followed carefully. However, certain precautions must be followed
during its use. To understand all the necessary precautions, the machine operator must read the
entire manual before operating or performing maintenance on the machine.
Operation and maintenance should only be performed by authorized and trained personnel. Below
are some basic safety guidelines:
yFollow local governing codes to ensure a minimum standard of safety.yWear protective gloves, eye protection and hearing protection.yOperate the machine in a well-ventilated work area.yFollow the prescribed maintenance schedule (see “Maintenance” on page 35).yStart up and shut down the machine according to the instructions in this manual.yDo not operate a machine that is damaged or in disrepair. yDo not store objects on top of machine hopper.
CO2 Safety
This machine uses dry ice (CO2 in solid form). The temperature of dry ice is -78.9°C (-109°F). Avoid
coming into direct contact with dry ice as it may cause severe tissue damage.
Study the material safety data sheet (MSDS) of dry ice (CO
) supplied with the delivery of dry ice and
2
follow all the recommendations and guidelines listed therein.
Operate the blaster in a well-ventilated work area with continuous CO
-level monitoring. The eects
2
of CO2 are entirely independent of the eects of oxygen deciency. Therefore, CO2 concentrations
at 3-5% causes headaches, fast breathing and discomfort while higher concentrations may cause
unconsciousness, suocation or respiratory arrest. The legal exposure limit set by OSHA is a 0.5%
average over an 8-hour workday and the acute (15 minute) exposure limit set is 3.0%.
Always use a CO
monitoring/alarm system when working with machinery that emits CO2 in a
2
conned room/space.
Electrostatic Discharge
Dry ice blasting may create electrostatic discharge(s). This machine is tted with eective
electrostatic dischargers to prevent injury or damage. Also, the machine must be plugged into a
properly grounded electrical outlet.
It is recommended to avoid operating the machine near explosive or ammable material. Also, use a
plastic shovel when handling dry ice to eliminate any additional static electricity.

maintenance personnel should familiarize themselves with these safety labels and warning signs.
Replace any safety labels or warning signs if they become damaged, missing or illegible.
Cautions and Warnings
Please review the following cautions and warnings before operating or performing maintenance on
the machine.
CAUTION Read the instructions before using the machine. Only qualied personnel
should operate the PLT 60.
WARNINGEnsure adequate ventilation when operating this equipment to prevent the
build-up of carbon dioxide gas. If used indoors or other conned space, a CO
detector should be used to monitor for excessive unsafe levels of CO2 gas and
provide a suitable warning.
2
WARNINGEnsure that expended dry ice pellet emissions are not in the vicinity of air
ventilation.
WARNINGThis 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 aect the safety of the machine.
WARNINGHigh pressure jets can be dangerous if subject to misuse. The jet must not be
directed at persons, live electrical equipment or the machine itself.
WARNING Do not use the machine within range of persons unless they wear the
personal protective equipment (PPE).
WARNINGDo not direct the blast stream against yourself or others in order to clean
clothes or foot-wear.
WARNING High pressure cleaners shall not be used by children or untrained personnel.
5
WARNING High pressure hoses, ttings and couplings are important for the safety of the
machine. Use only hoses, ttings and couplings recommended by Cold Jet.
WARNING To ensure machine safety, use only original spare parts from Cold Jet or
approved by Cold Jet.
WARNING The applicator and applicator hose contain electrical connections. Do not
immerse in water.
WARNINGDo not use the machine if a supply cord or important parts of the machine are
damaged, (e.g. safety devices, high pressure hoses, applicator).
WARNINGInadequate extension cords can be dangerous. If an extension cord is used, it
shall be suitable for the environment in which it is used. If used outdoors the
connection has to be kept dry and o the ground. It is recommended that this
is accomplished by means of a cord reel which keeps the socket at least 2.4
inches (60 mm) above the ground.
WARNINGAlways switch o the main disconnecting switch, or unplug the blaster power
cord when leaving the machine unattended.
