Danger
Risk of suffocation on account of carbon di-
oxide. The carbon dioxide content in the air
at the place where the machine is used will
increase when the machine is running. En-
sure adequate ventilation at the place of
use; if possible, use an alarm to warn per-
sons. Symptoms of high levels of carbon di-
oxide in the air that is breathed in:
– 3...5%: headache, faster breathing.
– 7...10%: headache, nausea and per-
haps even unconsciousness.
If any of these symptoms occur, please
switch off the machine immediately and get
a breath of fresh air and improve the venti-
lation before starting work again with the
machine.
Follow the safety specifications of the man-
ufacturer of carbon dioxide.

ture of -79 °C. Never touch dry ice or cold
parts of the machine without appropriate

pellets. Inspect the pellet ejector for cleanli-
ness prior to taking it into operation. Do not
