be kept dry and off 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.
Ensure that the extension cord is properly sized for the machine electrical
requirements.
Always switch off the main disconnecting switch, or unplug the blaster power cord,
bleed any pressure, and disconnect the air supply when leaving the machine
unattended or shutting down. Reel the power cord up to the machine and place a
locking device over the plug of the unit when Lockout Tagout is necessary.
Ensure all machine covers are in place before operating the machine.
Dry ice blasting may create electrostatic discharges which may harm personnel. Ensure
that the surfaces being cleaned are properly grounded with the supplied grounding
cable.
• Throughout this manual, Lockout Tagout will be referred to in instances when power must be
removed from the machine.
• There are universally accepted basics to this procedure. The minimum steps are listed below but
may not be limited to these steps; each individual entity owning and/or operating a machine
may have their own additional procedures.
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 the power cord within visual distance of the machine.
c. Turn off the compressed air supplying the machine.
d. Turn the air bleed knob on the right side of the machine to the open position.
