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 flow 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 fixed 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/m
3
(fine 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 specific 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 CO
2
pellets 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
airflow. 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.
